Chapter 1

Introduction to OpenClovis IDE

OpenClovis Integrated Development Environment (IDE) is designed to simplify and accelerate the development of application service platforms for the telecommunication market place. Coupled with the OpenClovis ASP,this intuitive software solution streamlines the process of specifying the information model, High Availability (HA) aspects and the communication infrastructure of a system. OpenClovis IDE stores all information describing a project in well defined XML files that can be modi?ed by the user. Modeling of system resources and relationships are speci?ed using a graphical UML editor. This chapter familiarizes you with the main concepts and features of OpenClovis IDE.

Basic Concepts

OpenClovis IDE Features

OpenClovis Value Proposition

1.1 Basic Concepts

OpenClovis IDE is an Integrated Development Environment (IDE) designed to simplify and accelerate the development of Telecom application software over OpenClovis platform. It provides a simple and powerful mechanism with easy drag-and-drop features, to create Resources and Components and define their attributes and relationships between them. OpenClovis IDE enables you to capture this model through UML notations and then save them as XML files.

Openclovis IDE is built using the Eclipse platform, hereby it inherits some functionality from it. It has a modeling framework and code generation facility for building tools and other applications based on a structured data model, from a model specification described in XML

This document refers only to the features of the OpenClovis IDE product and not those of the Eclipse platform.

OpenClovis IDE enables you to rapidly create a model of the Resources and generates customized code for OpenClovis. Apart from enabling to easily generate code, it also provides the capability to compile and deploy the code to the target system under development.

OpenClovis IDE allows you to model the following elements:

Physical Resources
Logical Entities

OpenClovis IDE provides two basic views of the system; physical (or resource) view and logical (or component) view. These two views are linked with each other.

Physical (or resource) view: The physical (or resource) view allows the modeling of the physical containment aspects of the system, working with chassis, blades, daughter cards, network ports, other physical devices, and software entities running on such cards and devices. The physical containment hierarchy is used to define the Managed Object(MO)tree and to derive the MO path (addressing) information.

Logical (or component) view: The logical (or component) view is a service availability view of the system, using concepts such as cluster, nodes, service units, service groups, service instances, component service instances, proxy components, non-proxy components, and proxied components.

1.1.1 Information Modeling Using IDE

The OpenClovis Information Model is a generic framework or an abstract representation of the entities in a managed environment. The OpenClovis IDE enables you to build an Information Model using UML notation.
An Information Model (IM) presents a unified view of different components of a system and abstracts hardware and software running on a system, from an end user. IM provides a unified view and association of all the physical and logical objects in the managed environment.
The advantages of Information Modeling are:

Managed Objects: Allows the definition of MOs for a OpenClovis-based system covering chassis management, devices, alarms, faults, component states, and provisioned attributes of OpenClovis components and customer applications.

Strong integration with system model: Information model is created as the user is working on the system model. For instance, when an alarm is defined for a physical or logical component, the related alarm MO attributes are automatically added to the information model. *

SNMP MIB import: To speed up MO definition and/or to design an information model that is compliant with existing models,one or more SNMP MIB files can be imported in to a OpenClovis IDEproject. The user can select one or more objects from the MIB tree and add them to an MO class definition. MIB attributes will become MO attributes with the same name, type, and access mode. To maintain compatibility with the MIB, SNMP OIDs are preserved and attribute names, type, and access modifiers can be locked to prevent deviation from the imported model. SNMP traps can be added as alarms. If needed,proprietary attributes can be added to an imported object, resulting in a new object class.

SNMP MIB export: Parts of or the entire newly defined information model can be exported as new, proprietary MIB(s).

OID/MOIDmapping: OpenClovisIDE generates the necessary bi-directional mapping between the OIDs used by the SNMP agent and the MOIDs used by OpenClovis COR OpenClovis IDE.

For information about building a sample model using OpenClovisIDE,see OpenClovis Sample Application Tutorial .

1.2 OpenClovis IDE Features

OpenClovis IDE provides the following important features:

Modeling: Modeling is performed using the Resource Editor and Component Editor pane, along with the definition of the relationship, and its validation. The properties of each of these resources are also set during the development of the Information Model.

Configuration: Configuration is related to the configuration of modeled entities, OpenClovis components, alarms set for the resources, generated source code,and the generation of the configuration files needed for OpenClovis ASP customization, including build-time, boot-time, and run-time configuration files.

Boot and run-timeconfiguration: OpenClovis IDE generates the various XML files used by OpenClovis. Boot-time configuration includes boot-levels, services to start per boot level, and node role profiles (personalities).

Code generation for OpenClovis customization: To facilitate build-time customization for OpenClovis, OpenClovis IDE generates C header files to be linked with OpenClovis libraries to result in customized OpenClovis server executables. During code generation,the correct files are generated in the predefined directories and file structures.

Application stub generation: OpenClovis IDE also generates application skeletons (stub code) for EOnized customer applications.

Eclipse based IDE for System and Information Modeling: Powerful,Eclipse based graphical user interface for system modeling, information modeling, and ASP-based product development.

UML Based: Model components and their relationship such as containment, aggregation, and inheritance, are edited using a graphical UML editor.

Projects Based: Modeling work files are organized into projects. Many model artifacts are reusable across projects.

XMI import: UML models (if satisfying certain restrictions) can be imported from other tools using XML Metadata Interchange (XMI) compliant files.

Integrate with other IDE Tools : Due to its Eclipse based nature, IDE can be integrated with other Eclipse based IDEs.

Template support: A library of pre-defined model fragments (templates) are provided, jump-starting the system modeling work when working with common objects such as standard chassis, system controller cards, line cards. For specific hardware models (chassis and cards) a palette of fully detailed and complete object models are available.

The following are a few additional features provided by the OpenClovis IDE:

Facilitates easy drag and drop of resources and components.

Validation of a model. View the existing projects in the OpenClovis IDE Workspace.

Importing OpenClovis IDE Projects.

View a MIB File through the OpenClovis MIB explorer.

Generation of source code and configuration files.

Outline view for editors.

CHAPTER 2

Getting Started

This chapter provides information to launch and access IDE, create a workspace, and a new project.

Key Topics:

Creating Project Area
Launching OpenClovis IDE and setting Up My Workspace
Creatin OpenClovis IDE Project
Setting Project Properties

2.1 Creating Project Area

After installation, create a new project area at /home/clovis/projectarea1 by executing the command:

<install_dir>/6.1/sdk/bin/cl-create-project-area /home/clovis/projectarea1

This will prepare /home/clovis/projectarea1 for use with the OpenClovis IDE and SDK.

A project area allows you to create and develop one or more system models with the required ASP-based components. The project area can hold multiple models and you can switch between these models. All the models in the same project area share the same ASP source tree,there by any modifications to the ASP source tree, are re-used across all the projects that are available in the project area.

After creating a new project area, you can create one or more system models with the required ASP based components.

2.2 Launching OpenClovis IDE and Setting Up My Workspace

You launch the OpenClovis IDE from the command line. If you chose to create symbolic links during installation you can simply enter cl-ide from any directory. If you did not create symbolic links during installation you can either:

Add the installation directory to the shells search path and then launch the IDE. For example with a bash shell,

   # export PATH=$PATH:$install_dir/6.1/sdk//bin 
   # cl-ide 
or

Execute the command

    # <install_dir>/6.1/sdk/bin/cl-ide

The splash screen for SAFplus Platform IDE is displayed

SAFplus Platform IDE Opening Screen

The Workspace Launcher window is displayed

SAFplus Platform IDE Workspace Launcher

Enter the location of the workspace and click OK. The value in this field will de- fault to the ide_workspace directory below the last project area that was created

using the cl-create-project-area command. If you wish to use a differ- ent workspace then select the ide_workspace directory under any other valid project area.

To set the selected workspace as the default, select the Use this as the default and do not ask again checkbox.

SAFplus Platform IDE Welcome Screen

If the error Workspace already in use is displayed when launching the OpenClovisIDE check the processes that are running. If the Eclipse process is running, then terminate the Eclipse process and re-launch OpenClovis IDE.

2.2.1 Understanding My Workspace

The Clovis Workspace pane displayed on the left side of the OpenClovis IDE window lists the projects that belong to that workspace in an alphabetical order. It also displays the defaul tfolders and files that are generated for every project. The generated files include OpenClovis configuration files, UI model files, templates, and scripts.

These files MUST NOT be modified as this may lead to unexpected result and the model may become invalid.

The Open Clovis configuration files are not visible in the general project view.

Initially, when you create a project, only the templates and idl folders are displayed in the Clovis Workspace pane. After the code generation step the src folder is also displayed. To display the other folders, click the arrow on the top right-corner of the Clovis Workspace pane and select Filters. The Navigator Filters dialog box is displayed. Clear the checkboxes for the folders that you need to view and click OK. If you clear all the checkboxes, then the folders shown in Figure OpenClovis IDE Workspace is displayed in the Clovis Workspace pane.

2.2.2 Viewing My Workspace

To view the workspace:

From the Window menu, click Show View, and then click Other. The Show View dialog box is displayed.
. Type the name in the text box or double-click Clovis and select Clovis Workspace.
. Click OK. The Clovis Workspace pane is displayed.

2.3 Creating OpenClovis IDE Project

To you create a project, you can start with a blank project or specify the resources and components using the wizard. If you start with a blank project, you need to use the Resource Editor and Component Editor Palettes to create your resources and components. The Wizard helps you to kick start a project by creating standard sets of objects based on the entry of a few key pieces of information.

To create a new OpenClovis IDE project:

1. From the File menu, point to New, and then click Project.... The New Project Wizard is displayed.

2. Type Clovis System Project in the text box or double-click Clovis, select Clovis System Project, and then click Next. The Clovis System Project window is displayed.

3. Enter the following information:

Project name: Name for your project.

Do not use spaces or special characters for the project name. The project name can be alphanumeric, but cannot start with a number. Select Use default to retain the default location of the project, or enter the location of the project contents.

SDK Location: Enter the location where the OpenClovis SDK was installed. This field is automatically filled if IDE is installed as part of OpenClovis SDK installation. This is usually <installed_directory>/6.1/sdk.

Project Area Location: Enter the location where the generated source code. and install images will be written. This field is automatically filled If IDE is installed as part of OpenClovis SDK installation.

Usualy this location will be created before start the IDE by using cl-create-project-area script. If not cl-ide script should create this location.

Python Location: This is the path of the python binary location that will help OpenClovis IDE in generating the code. Python 2.4.1 is required to be installed in the required location before using OpenClovis IDE to generate code. Python is usually located in /usr/bin folder. If Python is installed as part of OpenClovis SDK installation, then it is located at <installation_directory>/buildtools/bin.

Code generation mode: Select the code generation mode. Default value for this field is openclovis.

At any point from here on forward you can click Finish to create the project using the information that you have entered so far. If you choose to do this before getting to the end of the wizard you will need to create resources and components manually through the Resource and Component editors.

4. Click Next to specify the types and number of blades in your system. The Add New Blade Type window is displayed. Click Add to add a new blade type and enter it’s details.

Blade Type: Type of the blade. Select the type of the blade from the dropdown list.

Blade Name: Name for the blade type. This name must be unique within the model.

NumberofBlades: Number of blades of this type that will be present. For information about blade types refer to the Glossary.

5. Click Next to specify the SAF node types in the system. The Add New SAF Node Type window is displayed. Click Add to add a new SAF node type and enter it’s details.

6. Enter the following information:

Node Name: Name of the node type. This name must be unique within the model.

Node Class: Type of class to which the new node type belongs. Select one of the following options from the drop-down list:
- System Controller : Select System Controller if this node type will act as a System Controller.
- Payload Select Payload if this node type will act as a worker node, typically running application code.

For information about node and node class refer to the Glossary

7. Click Next to specify the SAF service types for the system. The Specify Program Names window is displayed. Click Add to add a new program (SAF Service Type) and enter it’s details.

8. Enter the following information:

Node Type: The type of node on which the program will run. Select from the list of node types defined on the previous page.

Program Name: Name of the program being defined. All elements of the SAF Service Type (service unit, service group, etc.) will be derived from this name.

9. Click Finish. The Resource and Component Editors display the specified blades and nodes along with their resources and components.

The Clovis Workspace pane lists the new project, its associated files, and directories. In this case,Sample Model is the name of the project. You can open and close projects in the Clovis Workspace by right-clicking and choosing Close/Open from the Clovis Workspace context menu.

2.4 Setting Project Properties

To set the properties for the project:

1. From the Project menu, choose Properties or right-click on the project and select Properties. 2. Select Clovis System Project. The Clovis System Project pane is displayed on the right-side. 3. Enter the following information:

Project Version: This is the version number of the project. This field is not editable.
Code generation Location: Location where you want to generate the source for your model.
Python Location: This is the path of the python binary location. Python is required by the OpenClovis IDE to generate code. Python is usually located in /usr/bin or in <sdk-dir>/build tools/bin if installed during ASP installation.

If you have specified the SDK, Project Area, and Python location while creating a new project,they will appear in the SDK Location,Project Area Location, and Python Location fields in the Clovis System Project window. If not, you need to specify these locations in this window before you generate the code.

Source Backup Mode: This option is used to indicate whether or not to backup the project’s existing source directory when new source code is generated. If the directory is not backedup then any manual changes that have been made to source ?les outside of the prescribed begin/end application code blocks or changes made to con?guration ?les will be overwritten. The possible values for this option are Always,Never,and Prompt. Prompt will ask the user each time that source code is generated.

Number of Backups: This option indicates how many number of source code back up should be preserved. Number should between 1 and 100. Default is 5.

Code generation mode: This option is used to select code generation option. IDE will generate the code with OpenClovis APIs If selected value is openclovis

IDE will not support code merging if a user switches between SAF and OpenClovis API code generation

Always override application code: Select this if you always want to overwrite existing model code with the code generated by the IDE. Note that with this setting you will lose any customization that you have made to IDE generated files.

Always merge application code: Select this if you always want to merge newly generated source code with the existing model code. With this setting all code between the prede?ned begin/end application code blocks will be preserved during code generation.

4. Click OK. The properties for the project are set.

When using the Export utility you may encounter an error indicating that resources are out of sync. To avoid this problem you need to configure the work space to refresh automatically. Do this by going to the ’Window | Preferences...’ dialog, navigating to the ’General –> Works pace’ pane, and clicking the check box titled ’Refresh automatically’. After applying this setting you should not longer receive the error

3.4 Using OpenClovis IDE Editors

OpenClovis IDE has two editors that allow you to model the resources and components. 
The two editors are:

Resource Editor

Component Editor

Manageability Editor

Performance Monitoring Editor

Resource and Component editors support scalable views of the class models to improve usability if you create a large model. All the objects are arranged row by row. The position for each object is based on the parent position. For example, if the parent object is placed in the first row, the child object is placed in the second row. Connection points for all edges will be rearranged based on the location of the source and target objects.

You can automatically arrange all the objects in the editors to provide a better layout. To do this, right-click in the Resource Editor or Component Editor, and click Auto Arrange. The objects are re-arranged

You can also collapse or expand the child objects that belong to a parent object. To collapse the child objects, right-click on the object and select Collapse. To expand the child objects, right-click on the object and click Expand.

In the Resource Editor you can create managed resources that are not related to any given blade or node and are directly linked to the chassy. For example, a distributed system consisting of many blades has some provisioned information that is system-wide and requires access from applications that reside on many blades.

3.4.1 Using Resource Editor

The Resource Editor is automatically displayed for a newly created project. A Resource Editor, by default, has a Chassis as a resource and helps you to:

Model the physical resources existing on a system.
Drag and drop(or use keyboard shortcut)to create all the resources to be managed using UML notations.
Double-click a resource to define its properties.
Specify the attributes Provisioning, Chassis Management, and so on.
Use a set of default, tailor-made resources in a Palette.
Use relation connectors to de?ne the relationship between the resources.

3.4.1.1 Resource Editor Palette

The Resource Editor Palette is displayed on the right side of the Resource Editor pane, when you select the Resource Editor tab. This Palette helps you to model there sources and define the relationship between there sources. The Palette comprises the following options with the keyboard shortcuts specified in brackets

Relationship
- Inheritance [Shift + I]
- Composition [Shift + C]
Resources
- Blade Type [Shift + B]
- Managed Resource [Shift + R

Space makes the editor go back to the Select mode.

The following table provides the representation of the various resource objects in UML in the Resource Editor.

Resource Object	UML Representation
Blade Type
Managed resource

Relationships:

Inheritance relationship indicates that one resource is created from another and therefore contains certain common features with the parent resource. Inheritance links generalized classes to their specializations. To create inheritance relationship between resources, click Inheritance in the Palette (or use keyboard shortcut) and create connection from one resource to another resource to inherit the pre-defined properties. The derived resource inherits only the attributes and not the alarms.

Composition relationship is a relationship where one resource consists or contains the other resource. To create Composition relationship, click Composition in the Palette (or use keyboard shortcut) and create connection from one resource to another resource. From a Physical perspective, a Chassis contains Blade Types that in turn, may contain Managed Resources.

3.4.1.2 Creating a Resource

You can create resources using the Resource Editor Palette or the Add New Blade wizard. To create a resource using the Resource Editor Palette:

Click any Resource in the Palette.
Drag the cursor onto the Resource Editor area. The cursor has an additional rectangle and + symbol,indicating that you are ready to create a Resource class model in Editor.
Drop the object in the Resource Editor area. The object is displayed in the Editor. You can specify the name and set the properties for the resource by double clicking on it or by doing right click on it and selecting Properties.

3.4.2 Using Component Editor

The Component Editor is automatically opened for a newly created project. Component Editor is primarily designed to cater to SAForum speci?cations and helps you to:

Define a logical view between all resources that are modeled in the Resource Editor.
Make associations with the defined resources.

SAFplus Platform Component Editor

The Component Editor by default always contains a Cluster. A Cluster is the entire system, containing multiple nodes.

A component is the smallest logical entity on which a fault recovery can be performed. The component could be a process, many processes or hardware. It represents a set of resources to the Availability Management Framework (AMF). The resources represented by the component encapsulate specific application functionality. This set can include hardware resources, software resources, or combinations of the two.

In the Clovis Workspace, a component is classified as a SA Forum Component or a Non-SA Forum Component.

3.4.2.1 Component Editor Palette

The Component Editor Palette is displayed on the right side of the Component Editor pane. This Palette helps you to model the components and define the relationship between the components.

To add an object (Node, SU, or Component) to the Component Editor, click the object in the palette and drag and drop (or use keyboard shortcut) the object in the Component Editor pane.

The Palette comprises the following options with the keyboard shortcuts specified in brackets:

Relationship
- Auto Relation [Shift + A]: drops a relationship edge between the components based on the type.
Node Hierarchy
- Node [Shift + N]: is the logical representation of a physical node.
- Service Unit [Shift + U]: is a logical entity that aggregates a set of components combining their individual functionalities to provide a higher level service.
- SAF Component [Shift + C]: is the smallest logical entity on which the Availability Management Framework performs error detection and isolation, recovery, and repair.
- Non-SAF Component[Shift+W]: are components that do not register directly with the Availability Management Framework. These components can be either Proxied or Non-Proxied depending on how they are associated with other objects in the editor. See Setting Non-SA Forum Component Details for more details.
Service Hierarchy
- Service Group [Shift + G]: is a logical entity that groups one or more service units to provide service availability for a particular set of service instances.
- Service Instance [Shift + I]: is the aggregation of component service instances.
- Component Service Instance [Shift + E]: represents the workload that the Availability Management Framework can dynamically assign to a component.

Assigning multiple name value pairs same CSI type will not be possible with current IDE.

The following table provides the UML representation of the various component objects in the Component Editor:

4.2.5 Associating Alarms

You have to define the alarms in the Alarm Profile window and then associate them to a resource and specify the generation rule for the alarm. For information about defining alarms, see Chapter 6 Defining Alarm Profiles. Association refers to associating the defined alarms to a particular resource. After associating the alarms to the resources, the generation rule has to be specified for the alarm to be generated.

To associate pre-defined alarms to a resource:

1. In the Resource Details window, double-click alarm Management and select Associate Alarms. The Associate Alarms pane is displayed on the right-side.

Associate Alarms

The alarms that are defined in the Alarm Profile window are listed under Available Alarms area.

2. Select the alarms that are applicable to this resource and click Add to move them under Selected Alarms for this resource.

Two alarms with the same probable cause cannot be associated to the same resource.

Add: This associates an alarm from the existing list to a resource.

Delete: This disassociates an alarm with a resource.

GenRule: Click this button to create a rule that defines the condition under which the selected rule will be generated. An alarm that does not have a Generation Rule associated with it will never be raised.

Suppress Rule: Click this button to create a rule that defines the condition under which the selected alarm will be suppressed.

For information about configuring the alarm rule, refer Configure Alarm Rule section.

Corresponding to the application that is managing the resource, the code for the associated alarms are generated in the cl<component_name>alarm-MetaStruct.c file located in the <projectarea_directory>/<model_name>/src/app/<component_name>/ directory.

4.2.5.1 Configure Alarm Rule

After you select the alarms that are to be associated with the resources you have to specify the alarm rule for the alarms to be raised/suppressed. The alarm rule can be a generation or a suppression rule. An alarm cannot be generated, if the alarm rule is not specified. Generation rule provides a mechanism to specify constraints on generation of alarms. Suppression rule specifies constraints on the suppression of alarms.

You can also specify a generation rule to model dependencies between alarms. A generation rule specifies the following:

Alarm to be generated
Dependent alarms
Condition that has to be satisfied for the alarm to be generated. This condition is specified as a logical relationship between the dependent alarms.

A suppression rule specifies the following:

Alarm to be suppressed
Dependent alarms
Condition that needs to be satisfied for the alarm to be suppressed. This condition is specified as a logical relationship between the dependent alarms.

An alarm rule can have a maximum of four alarms in an Alarm rule. An alarm rule can either have logical OR or logical AND operators but not both.

You can configure alarms in the Associate Alarms window.

Select the alarm for which you need to configure the generation rule/suppression rule and click GenRule or SuppressRule. The Alarm Rule dialog box is displayed.

From the Relation drop-down list, select the relation. Three relations are available:

CL_ALARM_RULE_NO_RELATION

CL_ALARM_RULE_LOGICAL_OR

CL_ALARM_RULE_LOGICAL_AND

Select the alarm(s) for which you need to apply the generation rule and click OK.

If you choose CL_ALARM_RULE_NO_RELATION, then you need to check only one of the alarms present under Select alarms for this rule. This alarm is the same alarm for which the generation rule/suppression rule is applied, that is the alarm that you selected under Selected Alarms while associating the alarms (in Figure Associate Alarms).

However, if you choose any of the other two relations, then you can select more than one alarm. Selected alarm should not be the same alarm for which the generation rule/suppression rule is applied, that is the alarm that you selected under Selected Alarms while associating the alarm (in Figure Associate Alarms).

CHAPTER 5

Defining Alarm Profiles

This chapter provides information about defining alarms to map to the resources. Any application can raise an alarm, on detecting an erroneous condition on a managed resource. You have to pre-define the variety of alarms to be raised in a system for different categories, probable causes, and severity types. All the categories and probable causes conform to the ITU-T X.733 standard. For each category, there is a different set of probable causes.

1. The alarms are defined in the Alarm Profile window. From the Clovis menu, click Alarm Profile... or press Shift+Ctrl+L on the keyboard to open the Alarm Profile window.

Alarm Profile

2. To create an alarm profile, click New and enter the following:

Severity: Select the Severity of the alarm from the list. The available options are:
- Critical
- Major
- Minor
- Warning
Specific Problem: An integer value providing more specific information about the alarm being raised.
Assert Soaking Time (Milliseconds): This is the time during which the alarm is observed before actually raising it as a genuine alarm.
Clear Soaking Time (Milliseconds): This is the time when the alarm is cleared.
Description: Enter any description for the alarm.

The alarm will be raised/cleared after the time interval specified in the Assert Soaking Time/Clear Soaking Time fields, for that particular alarm. If you want to raise the alarm instantly then the values of both the fields has to be 0.

3. Click OK. The alarms are saved.

A redundancy model associated with the SG defines how the service units in the group are used to provide service availability. A SG is defined at run time and dynamically populated with SUs as necessary.

A SG contains multiple SUs, all of which are functionally identical. Each SG follows rules that decide when to start SUs, stop SUs, assign, and remove work. An SG may have a preference for starting certain SUs first. There is no manual or boot-time starting of components unless the rules of the SG permit it.

For more information, refer Service Availability Forum Overview Document on the SA Forum Web site (www.saforum.org.)

Double-click a SG or right-click on it and select Properties. The Service Group Details swindow is displayed.

Enter the following information:

Name: Name for the Service Group (SG). You can enter only a valid string. It does not accept numerics, special characters, and spaces.
Redundancy model: The SUs within a service group provide service availability to the service instances that they support according to the particular SG redundancy model. The valid values are No Redundancy, 2N Redundancy, and M+N redundancy.
Delayed SG Instantiation Interval (milliseconds): The delay between the time the ASP comes up and this SG is started (instantiated).
Active SUs: Number of active Service Units (SUs). An Active SU is one that has been assigned "work" (i.e. an SI) and it is "doing the work" instead of "backing up" another SU.
Standby SUs: Number of standby SUs. A Standby SU is one that has been assigned as a backup for particular "work" that is active on another SU.
Inservice SUs: Number of In-Service SUs. This field allows the system to contain blades that do not have this SU running. For example, on a 3 blade system, setting this field to 2 would mean that 1 blade will not run the SU. This field can also be used to create "spares" or SUs that do not have any assignment ("active" or "standby") yet are ready to take an assignment (that is, the SU is running). For example, setting the "Assigned SUs" to 2 but setting this field to 3 will create 1 "spare" SU.
Assigned SUs: Maximum number of assigned SUs. The value should be 2 for the 2N Redundancy Model, or the sum of N+M in the N+M redundancy model.
Active SUs per SI: Number of active SUs per service instance. This is used to assign multiple SUs as "Active" to the same "work" (SI). For the 2N redundancy model, this must be 1. For example, in a 6+1 model, setting this to "2" would mean that 3 SIs are assigned "Active" to 3 pairs of blades.
Maximum active SIs per SUs: Maximum active service instances per SU. This is a opposite of the previous field, in that it allows you to assign multiple "Active" work to the same SU.
Maximum standby SIs per SUs: This field allows a single SU to act as a backup for multiple "Active" SUs. For example to implement 10+1 redundancy, this field must be 10. But to implement, say, 10+2 redundancy, setting this field to 5 would ensure that 5 SIs are assigned to each of the 2 backup blades (this assumes that "Standby SUs" is set to 2, and "Active SUs" is 10). Therefore, choosing a 2N redundancy model forces this field to be 1.
Component restart duration (milliseconds): (see below)
Maximum component restart count: These 2 fields control behavior during component failure. By setting these fields to non-zero, you may choose to have your component restart on failure and receive the same work (SI) assignments as it had before it failed. But if the component must be restarted "count" (see below) times within this time period, the fault is escalated to the SU level. For example, if the restart duration is 10000 (10 seconds) and the restart count is 5, then the system will try to restart the component 5 times. If these restarts occur in less then 10 seconds, then the fault is escalated to the SU level.
SU restart duration (milliseconds): (see below)
Maximum SU restart count:: The same restart logic as a component, but applied to an SU. For example, if you had 2 components associated with an SU then an SU restart would stop and restart both components (even if only 1 failed), and the original "work" reassigned. If the fault is escalated, then you get an SU failover (meaning that the work is assigned "Active" to the "Standby" SU).
SG fail-over duration (milliseconds): Specifies SG fail-over duration.
Maximum SG fail-over count: Specifies maximum SG fail-over count.
Admin state: Specifies the set administrative state and this also allows you to lock or unlock (start "LOCKED_A", stop "LOCKED_I", or assign work "UNLOCKED") an SG.
Loading strategy: Loading strategy to use when deciding how to assign SIs to SUs. Select one of the following options:
- Least SI per SU: In this strategy, the assignment algorithm tries to maximize the number of SUs assigned active and standby assignments, thus resulting in the least possible SI assignments per SU. This strategy is meaningful for the M+N redundancy model. (2N is a trivial case). This is the default strategy specified in the AMF specification.
- Least SU Assigned: In this strategy, the assignment algorithm tries to minimize the number of SUs that are assigned the active or standby SIs. This strategy is meaningful for the M+N redundancy model (2N is a trivial case) and is useful when assigning more SUs is costlier than adding new SIs to existing SUs and it is acceptable not to have the additional resiliency provided by not having the max possible number of SUs assigned.
- Least Load per SU: In this strategy, the assignment algorithm picks the SU with the lowest load to be the next candidate. The definition of load is intended to be customizable for a particular deployment.
- SI preference: In this strategy, the assignment algorithm tries to assign the SIs to the SUs based on the preference list associated with each SI. SIs with higher rank have first dibs. The preference is only for the active assignment and if the preferred nodes are not available, the algorithm defaults to LEAST_SI_PER_SU.
- User defined: This is intended to be an user customizable strategy that is plugged in during system deployment.
Auto repair: By default, it is marked as False. If set to true, then after a fail-over the AMS will repair the entity (i.e. restart the component – work assignments are not preserved) by itself without any administrative intervention. This can be used for software components. This is different then the "restart count" and "restart duration" fields because this field define actions taken AFTER a component fail-over. Note, a node fail-over requires administrative intervention to restart.
Collocation Allowed: If set to true, this parameter communicates to AMS that it can assign both active and standby SUs on the same node for a given SG. Currently, this is the default behavior. For example, when set to "true" this implements software-only redundancy (since your active and standby could be on the same node). Setting this to "false" implements both software and hardware redundancy.
Alpha factor: This property is only used for the M+N redundancy model. This allows AMS to assign standby assignments when the total number of assignable SUs is less then M+N. Alpha value is the percentage of the total available SUs which should be used for active assignments when the preferred configuration cannot be fulfilled. The possible value is between 1-100. The default value is 100.
Auto Adjust: This property is used to adjust the SG back to the most preferred assignments based on the SU rank.
Auto Adjust Probation(milliseconds): This is used to start a probation timer after the SU is repaired.
Reduction Procedure: This describes optimal assignments if the preferred number of its service units can actually be instantiated during the cluster startup. In the event that a service unit or a node fails to instantiate during cluster start-up or is administratively taken out of service, a reduction procedure is described in most of the redundancy models. The Availability Management Framework uses this reduction procedure to compute less optimal assignments before actually starting to assign the service instances.

Click OK. The properties for the SG is saved.

6.5 Setting SA Forum Component Details

Components must be designed so that the AMF dynamically assigns workloads to a component and chooses the role in which the component operates for a specific workload. Only local components that are under the direct control of the AMF can have a high level of integration with this framework. Such components are called SA Forum components. SA Forum component is capable of running OpenClovis services.

Each SA Forum component includes one or more processes that are linked to the AMF library. One of these processes registers the component with the AMF. This registered process provides AMF references to the availability control functions it implements. The AMF uses these control functions to direct component execution. For example:

Assigning workloads to the component
Removing workloads from the component
Assigning the High Availability state to the component for each workload

The registered process executes the availability management requests it receives from these control functions and conveys such requests to other processes and the hardware equipment of the local component, where necessary.

For more information, refer Service Availability Forum Overview Document on the SA Forum Web site (www.saforum.org.)

Double click the SA Forum Component or right-click on it and select Properties.

The SA Forum Component Details window is displayed.

6.5.3 Specifying Timeout Details

Operations such as instantiation, termination, and cleanup must be completed within the specified time frame for the corresponding components. The default timeout is 10000 milliseconds.

The Component Timeout Details window is used to specify the timeout details.

Enter the following information:

Instantiate timeout (milliseconds) - This is the time limit for the component instantiation to complete. For SA Forum components, it also includes the time required for the newly instantiated component to register with the Availability Management Framework. If the instantiation of the component does not complete in the specified time period, the error report is generated on the failed component and the cleanup operation is performed.
Terminate timeout (milliseconds) - This is the time limit for terminating the service provided by an instance of a component. The terminate operation stops the service in such a way that it could be resumed by another instance of the same component or another component with minimal disruption.
Cleanup timeout (milliseconds) - This is the time limit to complete the cleanup operation for a component. When recovering from errors, if a particular instance of the component is not terminated, the AMF forces a cleanup of the component.
CSI set timeout (milliseconds) - AMF assigns CSIs to the application components via a CSI set callback. This is the time AMF will wait for a response from the component for a previous CSI set call. If a response is not received or response indicates an error, AMF will declare an error on the component and take the necessary recovery actions. Multiple CSI set actions can be pending for a component at any given time. The component can send a response for each separately or all together but they should all be received within the specified timeout.
CSI remove timeout (milliseconds) - AMF removes CSIs from application components via a CSI remove callback. This is the time AMF will wait for a response from the component for a previous CSI remove call. If a response is not received or response indicates an error, AMF will declare an error on the component and take the necessary recovery actions. Multiple CSI remove actions can be pending for a component at any given time. The component can send a response for each separately or all together but they should all be received within the specified timeout.
Quiesing complete timeout (milliseconds) - AMF quiesces CSIs from application components via a CSI quiesce callback. This is done as a result of a graceful "shutdown" administrative operation that affects CSIs assigned to the component. This is the time AMF will wait for a response from the component for a previous CSI quiescing call. If a response is not received or response indicates an error, AMF will declare an error on the component and undertake appropriate recovery actions. Multiple CSI quiescing actions can be pending for a component at any given time. The component can send a response for each separately or all together but they should all be received within the specified timeout.
Proxied component instantiate timeout (milliseconds) - This is the time limit for the proxied component instantiation to complete.
Proxied component clean up timeout (milliseconds) - This is the time limit to complete the cleanup operation for a proxied component.

6.6 Setting Non-SA Forum Component Details

A Non-SA Forum Component is an entity that does not register directly with the AMF. Because of this they do not normally perform as efficiently in the areas of workload assignment, error detection, and recovery. Non-SA Forum Components are normally used only to link legacy applications to the AMF. There are two kinds of Non-SA Forum components. These are proxied and non-proxied.

Proxied Non-SA Forum Components are registered with the AMF by dedicated SA Forum components, which act as proxies between the AMF and the non-SA Forum components. These dedicated SA Forum components are called proxy components. The AMF manages the proxy component, calling its initialization routine, assigning it work, etc. The proxy component is responsible for conveying requests made by the AMF to its proxied components.

Non-Proxied Non-SA Forum Components have a less formal relationship with the AMF. For these components the role of the AMF is limited to the management of the component lifecycle. The AMF instantiates these components when the component needs to provide a service and terminates them when the component must stop providing the service.

For more information, refer Service Availability Forum Overview Document on the SA Forum Web site (www.saforum.org.)

CHAPTER 7

Configuring ASP Components

This chapter provides information to configure the OpenClovis ASP components within OpenClovis IDE using the "ASP Component Configuration" dialog box. These settings are separated into two categories: build time and boot time settings.

Key Topics:

Configuring Build Properties

Configuring Boot Properties

Build time settings are stored in the compileconfigs.xml file in the project’s config directory. These settings are used at compile time and changes to this file require a recompile and a redeployment to take effect .

Boot time properties are stored in .xml files in the project’s config directory. These files are clLog.xml, clSlotInfo.xml, and clGmsConfig.xml. These files are read at boot time and can be changed on the target system without requiring a recompile. ASP should be restarted on the target system when changes are made to these files.

From the Clovis menu, click ASP Component Configuration or press Shift+Ctrl+Y on the keyboard. The ASP Component Configuration window is displayed.

Maximum Shared Memory Pages: Maximum Number of shared memory pages (used for log write at the client side, these records are flushed to the actual file by the log server based on flush interval or flush frequency). If you want to use records of large size then you may need to increase this shared memory size.

Maximum Records In Pocket: The maximum number of records which log server picks at one time from the shared memory and sends the records for flushing to the actual file.

Perennial Streams Data - Click Edit to edit the Perennial Streams Data. The Stream Details window displays a list of Stream Types and their properties.

There are two pre-created perennial streams, app and sys. These log streams are created and opened automatically when ASP starts and are available as long as ASP is running. The sys stream is used by ASP system components for logging messages and information. The app stream is meant for use by application components for logging messages and information.

You cannot create new perennial streams.

Enter the following information:

Stream Name: Name of the stream.

File Name: Log file name to be associated with a particular log stream.

File Location: Location of the log file that can be defined by the user. The path can either be absolute (beginning with a /) or relative. If relative it will be placed in the specified directory under the ASP install directory. Additionally, this field must start with either a period (.) or an asterisk (*) followed by a colon (:). A period indicates that the log file should be written to the local machine. An asterisk indicates that the file should be written to the system controller.

File Unit Size (bytes): Size of the log file in bytes.

Record Size (bytes): Indicates the log record size in bytes.

File Full Action: Action to be taken when the file is full (WRAP, ROTATE, HALT).

Flush Interval(nanoseconds): The interval after which log records should be flushed to the log file. Log server choose the lower value out of ’flush frequency’ and ’flush interval’.

SysLog: Specify Yes for standard log.

Precreated Streams Data - Click Edit to edit the Precreated Streams Data. The Stream Details window is displayed. To create a new Stream Type, click New.

In addition to the perennial log streams described above you can create custom log files known as Precreated Streams. These streams can be used by applications to log error messages and information. Using multiple precreated streams, related information can be segregated into separate log files.

Enter the following information:

Stream Name: Name of the stream.

File Name: Log file name to be associated with a particular log stream.

File Location: Location of the log file that can be defined by the user.

File Unit Size (bytes): Size of the log file in bytes.

Record Size (bytes): Indicates the log record size in bytes.

File Full Action: Action to be taken when the file is full (WRAP, ROTATE, HALT)

Maximum Files Rotated: Maximum Number of files needs to be rotated when the File Full Action is ROTATE. This argument has to be set to 0 when file full action is WRAP or HALT.

Flush Frequency: The frequency of flushing the records to the log file. This takes a number and it means that after that number of records are written to the shared memory, the records should be flushed to the log file.

Flush Interval(nanoseconds): The interval after which log records should be flushed to the log file. Log server choose the lower value out of ’flush frequency’ and ’flush interval’.

SysLog: Specify Yes for standard log.

Stream Scope:This field determines the visibility of a stream. Stream scope takes following two values : [1] GLOBAL [2] LOCAL. Stream having GLOBAL scope has visibility across the cluster i.e. any process present in the cluster can use this stream for logging.

CHAPTER 8

Configuring AMF

This chapter provides information on creating the instances of the entities defined in the Component Editor using AMF Configuration. All the nodes and service groups in the system are instantiated using Availability Management Framework (AMF) Configuration. You can also configure the instance level parameters which are used by AMF.

AMF Configuration is a combination of AMS Configuration and CPM Configuration.

Key Topics:

Configuring AMF

Configuring CPM

From the Clovis menu, click AMF Configuration or press Ctrl+Shift+F on the keyboard to open the AMF Configuration window.

AMF Configuration

The Apply button will save all changes made since the dialog was opened or the Apply button was last clicked, leaving the dialog open.

The OK button will close the dialog saving all changes made since the dialog was opened or the Apply button was last clicked.

The Cancel button will close the dialog discarding all changes made since the dialog was opened or the Apply button was last clicked.

8.1 Configuring AMF Using the Wizards

The AMF configuration dialog provides two wizards which can help in creating the initial AMF instance model. Once an instance model has been created using the wizards it can be customized and maintained manually. To create an instance model using the wizards, first use the Node Creation Wizard to create the appropriate Node instances and then use the Service Group Creation Wizard to fill out the rest of the instance tree associating the newly created Service Group instances with the existing Node instances.

8.1.1 Node Creation Wizard

To access the Node Creation Wizard double-click AMF Configuration tree element in the left-hand pane and then click on the Node Instance List element. The Node Creation Wizard page is displayed.

Node Creation Wizard

The following values may be entered.

Node Type: Select the type of node to create. The list contains all of the node types defined in the component editor.

Blade Type: Select the type of blade to create. The list contains all of the blade types defined in the resource editor.

Node Count: Enter the number of node instances to create.

The Service Group table lists the Service Groups defined in the model and their redundancy models. You can use this information to help decide how many node instances to create.

Clicking the Create Instance Tree button will create the given number of node instances of the given type. Each node instance will be associated with the given blade type.

The total number of node instances associated with a given blade type may not exceed the Maximum Instances value entered for the blade type in the resource editor.

The number of node instances entered is usually equal to the total number of active and standby service units for all of the service group types associated with the selected node type in the component editor.

8.1.2 Service Group Creation Wizard

To access the Service Group Creation Wizard double-click AMF Configuration tree element in the left-hand pane and then click on the Service Group List element. The Service Group Creation Wizard page is displayed.

The following values may be entered.

Service Group Type: Select the type of service group to create. The list contains all of the service group types defined in the component editor.

Associated Node Instances: Select the existing node instances with which to associate the newly created service group instance.

Clicking the Create Instance Tree button will create a new service group instance along with its contained service instances and component service instances. It will also create a service unit instance and corresponding component instance under each of the associated node instances. Each service unit instance created will be associated with the newly created service group instance.

The number of service instances created below the service group instance will be based on settings made to the service group type in the component editor. The calculation is based on the number of active service units divided by the maximum number of active service instances per service unit.

The number of node instances selected must either be one or the total number of active and standby service units defined for the selected service group type in the component editor.

8.2 Configuring AMF Manually

AMF Configuration allows you to configure the following:

Node Instance List

CHAPTER 9

Configuring and Allocating Memory Configuration Profiles

This chapter provides information about configuring and allocating memory configuration profiles to the various ASP components and the user-defined EOs.

Key Topics:

Defining Memory Configuration Profiles

Assigning Memory Configuration Profiles to Components

9.1 Defining Memory Configuration Profiles

The memory configuration profiles are defined in the EO Definitions window. You can also use the default memory configuration profiles.

From the Clovis menu, click EO Definitions to open the EO Definitions window.

Memory Configurations

You can specify the following types of memory profiles:

Heap

Buffer

9.1.1 Creating Heap Memory Profile

Heap memory is used for dynamic memory allocation. Memory is allocated from a large pool of unused memory area called the heap. The size of the memory allocation can be determined at run-time. Heap includes all the pools of various chunk sizes.

To create a Heap memory profile:

1. In the EO Definitions window, double-click Memory Configuration in the left pane. Right-click Heap Config List and select New.

2. Enter the following information:

Name: Name for the heap memory profile.
Mode: Type of the heap allocation mode. The options available are:
- NM: This is the Native C Mode. In this mode, all requests are served by calling the OS memory allocation interface. It maps to the memory APIs provided by libc.
- PAM: This is the Pre Allocated Mode. It is the OpenClovis provided implementation of the memory management library. A large chunk of the memory is pre-allocated during component initialization. The memory space is divided into pools of diverse memory chunks and serves runtime dynamic memory allocation requests.
- CM: This is the Custom Mode. You can plug-in customized memory management library calls.
Lazy Mode : Configure the pool in lazy mode for pool expansion. When a pool exhausts its current allocation, it can still grow provided the dynamic memory space or the pool upper limit is not reached. It expands or grows by the increment size specified for the pool. In Lazy Mode, the incremented pool does not initialize until an allocation is made from that pool. In normal mode, the incremented pool initializes as soon as it is acquired by the memory management library.

Set the option to true or false.

Pool:Click Edit to enter the pool details.ThePool Detailswindow is displayed.

You can specify the pool details only if the allocation mode type is PAM.

Click New and enter the following information:

- Chunk Size: Piece of memory within the pool.
- Initial Size: Initial pool size for each pool.
- Increment Size: When the pool usage exceeds the initial size, the pool size grows by the increment size, unless the upper limit is already reached or the dynamic memory space is reached.
- Maximum Size: Maximum pool size for each chunk size.

If the memory usage exceeds the initial pool size, the memory manager requests for more memory (using the configured increment) from the system as long as the new pool size or the total dynamic memory usage does not exceed the specified upper limits.

The values are expressed in bytes.

Click OK The pool details are saved.

3. Click OK to save the memory profile.

9.1.2 Creating Buffer Memory Profile

The Buffer Memory provides buffers that can expand or shrink dynamically based on application requirement. The Buffer Memory is designed to provide an efficient method for management of user space buffer by avoiding data copy. It stores data for quick, temporary access.

The Buffer memory enable you to perform various functions such as, creating or deleting a message, and reading, writing and trimming the number of bytes from a message.

To create a Buffer memory profile:

1. In the EO Definitions window, double-click Memory Configuration in the left pane. Right-click Buffer Config List and select New.

2. Enter the following information:

Name : Name for the buffer memory profile.
Mode: Type of the heap allocation mode. The options available are:
- NM
- PAM
Lazy Mode : Set this option to true or false.
Pool : Click Edit to enter the pool details. The Pool Details window is displayed.

Click New and enter the following information:

- Chunk Size : Piece of memory within the pool.
- Initial Size : Initial pool size for each chunk size.
- Increment Size : When the memory usage exceeds the initial size, the chunk size grows by the increment size, unless the upper limit is already reached.
- Maximum Size : Maximum pool size for each chunk size. Click OK. The pool details are saved.

3.Click OK to save the memory profile.

9.1.3 Setting the Total Dynamic Memory Space, Watermarks, and Actions

You can specify the total memory usage space and also set three levels of watermark on the total memory consumption for each component instance. For each watermark the following attributes are configurable:

Lower Limit Value for downward crossing
Upper Limit Value for upward crossing
Set of actions to be executed in case the threshold limit is crossed. The actions include event posting, logging, notifications, and alarm generation.

For example, when 80% watermark is reached, a log message is logged.You can further alter the watermarks during run-time using MO instances that are associated with the software component instances.

To set the memory space:

1. In the EO Definitions window, double-click Memory Configuration in the left pane. Right-click Memory Config List and select New.

2. Enter the following information:

Name: Name for the memory profile.
Process Upper Limit: Upper limit for the total memory consumption.

Double-click the profile to display the three levels of watermark:

- High Water Mark
- Medium Water Mark
- Low Water Mark

3. Click on each Water Mark and enter the following information:

Low Limit: Memory limit value for downward crossing in bytes.
High Limit: Memory limit value for upward crossing in bytes.

4. Double-click each Water Mark to specify one or all of the following actions:

- Event
- Log
- Custom

Memory Config List Water Mark Event Action

5. Click Event and select true or false from the drop-down list. If it is set to true , event is enabled. Similarly, you can enable Log and Custom actions. 6. Click OK to save the memory profile.

9.2 Assigning Memory Configuration Profiles to Components

3. Enter a name for the template group and click OK. The name is displayed in the Manage Template Group(s) window and it is available under the templates folder in the Clovis Workspace Pane.

Click Rename to rename the selected template group.

Click Remove to remove the selected template group.

10.2 Using Template Groups

After you have completed creating the template group, you can assign it to the various SA Forum components in the Component Editor. By default, the default template group is associated to the components. You can also associate the user defined template group.

To assign the template group to the SA Forum component:

1. From the Clovis menu, click Associate Template Group or click the icon on the toolbar. The Associate Template Group window displays all the SA Forum components in the Component Editor to which you can assign the template group.

Associate Template Group

2. Select the template group from the list and click OK. The template group is assigned to the SA Forum component.

10.3 Modifying Template Groups

After creating template groups, you can customize the template groups per model as well as per application. All the templates will be availabe under templates folder. If you want to use the modified template files for entire model, modify the template files which are under templates/default. If you want to use the modified template files for any one of the application, modify the template files which are under templates/<TemplateGroupName>.

templates folder contains two type of templates:

python template files

.c and .h files.

Most of the python template files have two type of template static and runtime. static python templates are simply copied in some of the .c or .h files through python script at the time of code generation. static python templates are looks like:

headerTemplate = Template("""\ ClRcT clProvRead(CL_OM_PROV_CLASS* pThis, ClHandleT txnHandle, ClProvTxnDataT* pProvTxnData) { ClRcT rc = CL_OK; return rc; } """)

runtime python templates are copied in some of the .c or .h files with some modifications through python script. Modifications will happen based on some xml entries. runtime python templates are looks like:

headerTemplate = Template("""\ ClRcT cl${compName}${res}ProvRead(CL_OM_PROV_CLASS* pThis, ClHandleT txnHandle, ClProvTxnDataT* pProvTxnData) { ClRcT rc = CL_OK; return rc; } """)

Values for compName and res will be substituted through python script at the time of code generation.

All the .c and .h files will be copied to app/<CompName> folder at the time of code generation.

10.3.1 Adding Application Code Blocks

If you want to use same TemplateGroup for multiple applications and also you want to write some apllication code in generated source files, identify the blocks in template(s) which you will modify after generating the source. Insert this tag in each blocks,

# ---BEGIN_APPLICATION_CODE---

# ---END_APPLICATION_CODE--

or

/* ---BEGIN_APPLICATION_CODE--- */

/* ---END_APPLICATION_CODE--- */

This code blocks will be used to identify the user code. After generating source you can use this blocks to add your application code. Next time when you generate source all the code with in the blocks will be moved in to newly generated code.

CHAPTER 11

Defining IDL

This chapter provides information about creating the IDL XML file that is used to generate marshalling and unmarshalling code for communication between two or more components.

The OpenClovis Interface Definition Language (IDL) is a library used by all components to communicate efficiently with other components. Using IDL, OpenClovis ASP services can communicates across different endian and mixed mode (32-bit and 64-bit architecture) machines.

IDL generated code is a wrapper over RMD and supports RMD functionality to provide communication across components. RMD consists of an engine which provides the ability to invoke methods from one component to another component. By defining an IDL, the XML file is created which is read by the Python script and the C code is generated. The created XML file is located in your workspace and the generated C code is located in the <projectarea_directory>/<model_name>/src/app/idl folder. You can customize this XML file for your specific requirements.

Each component may define a set of operations associated with it. The RMD calls are defined through the functions defined in the component. The component from where the call or request is invoked is called the source and the component that receives the request is called the destination. When a remote call is invoked, the RMD sends a message to the destination using the underlying IOC transport layer. The component that receives the request invokes the function that is being requested.

Components can expose different types of services. Services of one component are grouped under service group. Each service has a operation group that logically separates the functions of a service. Hence, to define an IDL, you have to create the service group list that consists of services, operation groups, and the associated arguments. You can also create the data types required for the arguments such as structures, unions, and enumerations.

Key Topics:

Defining Service Group List

Creating User Defined Data Types

11.1 Defining Service Group List

A Service Group List comprises the following:

Service Groups
Services
Operation Groups
Operations

To define the Service Groups:

1. From the Clovis menu, select Remote Method Definitions or press Shift+Ctrl+I on the keyboard. The RMD window is displayed. In this window, you can specify the services for each component.

2. Right-click Service Group List and select New to create a new service group. Select the service group from the drop-down list.

This list displays the list of service group provided for all the components.

3. Double-click the newly created service group to display the Service List.Right-click and select New.

Enter the following information:

Service Name: This is the name of the service in which the operations of the service resides. Enter a valid C identifier.
Use Native Table: If a component is providing service to other component(s), the native (default) table is used. Select true or false from the drop-down list. If you set this to true , the default table is used. If it is set to false , another table is generated automatically by IDL. This is typically used when the response message is sent by invoking an operation on a caller.

4. Double-click the created service to display the Operation Group List. Right-click and select New to create a new operation group.

Enter the following information:

Operation Group Name: This is the name for the operation group that consists of the functions. You can define more than one operation group to logically separate the functions for a service. Enter a valid C identifier.

5. Double-click the created operation group to display the Operation List.Right-click and select New to specify the operations or functions.

Enter the following information:

Operation Name: Name for the operation or function associated with the component to which RMD calls can be made. Enter a valid C identifier.
Arguments: Click Edit to enter the argument details for the operation. Argument is similar to a data member. Argument details consists of the input or output parameters associated with this operation. The Argument Details window is displayed. Click New to create a new argument.

Enter the following information:

Parameter Type: Type of the parameter for the argument. Select the parameter type from the list. The options available are:
- CL_IN: This argument parameter is an input to the operation.
- CL_OUT: This argument parameter is used to return the value back to the caller.
- CL_INOUT: This argument parameter is an input to the operation and is also used to return the value back to the caller.
Name: Name of the argument. Enter a valid C identifier.
Data Type: Data type for the argument. Select the data type from the list.

The pre-defined data types available are:

- ClInt8T
- ClUint8T
- ClInt16T
- ClUint16T
- ClInt32T
- ClUint32T
- ClInt64T
- ClUint64T
- ClCharT

You can also have user defined data types like Structures, Unions, or Enumerations. For information about creating user-defined data types, see Creating User Defined Data Types section. After you create the user-defined data type, they will appear in this drop-down list.

Pointer: If the argument is of pointer type, select the level of indirection. The available options are:
- None
- Single
- Double

All CL_OUT type of argument must be either single or double pointer. CL_IN or CL_INOUT argument type cannot be a double pointer.

Length Variable: If the argument is of the pointer type, select another argument that contains the length of the data pointed by this argument. The default value is None. If you create other arguments, they appear in this list.

You can specify the Length Variable when the argument type is a single pointer or when the argument type is CL_OUT and is a double pointer. If the argument is of the pointer type and length variable is None , the length of the data pointed is of the defined data type within the argument.

6. Click OK. The Arguments Details window closes.

7. Click OK. The IDL is saved and the XML file is located in the idl folder in your workspace.

11.2 Creating User Defined Data Types

IDL uses XDR representation to Marshall application data while transferring it to another component. Therefore, IDL requires the application to specify the data structures to be transferred through RMD, so that it can generate XDR functions required to marshal/un-marshal these data structures. Marshaling is the process of converting the native data to XDR format and un-marshaling is retrieving the data back to native format. You can define the following user-defined types for each component:

Structures

Unions

Enumerations

11.2.1 Defining Structures

Structures are similar to structures in C. Therefore, every defined structure is composed of data members. You can define two structures separately and embed one inside another as a data member.

You can define structures in the RMD window. Right-click on the Struct List tand select New. STRUCT0 is created by default under Struct List.

Enter the following information:

Name: This is the user-defined structure name. Enter a valid C identifier. When you rename the structure, the new name replaces the default name on the left pane.

Struct Member: Click Edit to specify the data member details. The Data Member Details window is displayed. Click New to enter a new data member.

Enter the following information:

1.Name: :Name of the data member of the structure. Enter a valid C identifier.

2.Data Type: Data type of the structure member. This can be a pre-defined data type or a user-defined type. Select the data type from the drop-down list. It is the your responsibility to ensure that there are no circular inclusions. Circular inclusions occur when two or more user-defined data types include each other in their respective definitions in such a way that it creates a cyclic dependency among st the involved user-defined data types.

3.Pointer: Select the value from combo-box to specify whether the structure member is a pointer or not. When Single is selected, it means that the data member is a pointer to the specified data type. The options available are:

None
Single

4.Length Variable: If the structure member is not a pointer, select None. Otherwise, select the name of the other member in this structure that contains the length of the data pointed by this member. This attribute should be specified only if the pointer type is set to Single. This attribute specifies which data member in the structure will contain the number of elements being pointed to. When none is specified for a pointer type data member, it is assumed that a single element is being pointed to.

5.Multiplicity: Defines the number of elements in the array. Used only if the attribute is an array. This attribute must not be specified along with the pointer attribute.

Click OK. The data member details are saved and the Data Member Details window closes.

Generate Definition: Select this option to specify the definition for the user-defined data type. If you select true, Include Header File Path option is disabled and definition will be generated during code generation. If set to false, you must provide the path for the .h file that has the definition.

Include Header File Path: Click Edit to include the path. Specify the path for appropriate .h file and click OK. If you select Generate Definition as false, then you must provide the path.

Click OK. The structure is created.

11.2.2 Defining Union

These are defined similar to structures. The difference is in terms of the interpretation and generation.

You can define unions in the RMD window. Right-click on the Union List and select New to create a new union. UNION0 is created by default under Union'List'.

Enter the following information:

Name: This is the union name. Enter a valid C identifier. When you rename the union, the new name replaces the default name on the left pane.
Union Member: Click Edit to specify the data member details. The Data Member Details window is displayed.

Enter the following information:

- Name: :Name of the data member of the union. Enter a valid C identifier.
- Data Type: Data type of the union member. This can be a pre-defined data type or a user-defined type. Select the data type from the drop-down list. It is the your responsibility to ensure that there are no circular inclusions. Circular inclusions occur when two or more user-defined data types include each other in their respective definitions in such a way that it creates a cyclic dependency among est the involved user-defined data types.
- Pointer: Select the value from combo-box to specify whether the union member is a pointer or not. When Single is selected, it means that the data member is a pointer to the specified data type. The options available are:
  - None
  - Single
- Length Variable: If the union member is not a pointer, select None. Otherwise, select the name of the other member in this union that contains the length of the data pointed by this member. This attribute should be specified only if the pointer type is set to Single. This attribute specifies which data member in the union will contain the number of elements being pointed to. When none is specified for a pointer type data member, it is assumed that a single element is being pointed to.
- Multiplicity: Defines the number of elements in the array. Used only if the attribute is an array. This attribute must not be specified along with the pointer attribute.

Click OK. The data member details are saved and the Data Member Details window closes.

Generate Definition: Select this option to specify the definition for the user defined data type. If you select true, Include Header File Path option is disabled and definition will be generated during code generation. If set to false, you must provide the path for the .h file that has the definition.

Include Header File Path: Click Edit to include the path. Specify the path for appropriate .h file and click OK. If you select Generate Definition as false, then you must provide the path.

Click OK. The union is created.

11.2.3 Defining Enumeration

Enumerations are similar to enums in C. You can define enumerations in the RMD window. Right-click on the Enum List and select New to create a new enum. ENUM0 is created by default under Enum List.

Enter the following information:

Name:This is the enumeration name. Enter a valid C identifier.

Enum Member:Click Edit. TheEnum Member Detailswindow is displayed. Click New to create new enumeration data member.

Enter the following:

1.Name: Name of the data member of the enum. Enter a valid C identifier.

2.Value: Value for the data member. Click OK. The data member details are saved and the Enum Member Details window closes.

Generate Definition: Select this option to specify the definition for the user defined data type. If you select true, Include Header File Path option is disabled and definition will be generated during code generation. If set to false, you must provide the path for the .h file that has the definition.

Include Header File Path: Click Edit to include the path. Specify the path for the appropriate .h file and click OK. If you select Generate Definition as false, then you must provide the path.

Click OK. The enumeration is created.

CHAPTER 12

Generating Source Code

This chapter provides information about generating the source code after you have completed building the model.

To generate the code, in the OpenClovis IDE window, from the Project menu, click Generate Source. On successful generation of the source code, a message is printed on the Console pane at the bottom of the OpenClovis IDE window.

Code Generation Confirmation Message

The generated source code is located at <projectarea_directory>/<model_name>/src directory. The projectarea_directory is specified in the Clovis System Project window.

As source code is generated it is copied, along with various configuration files from the IDE model to the ASP model. Although not recommended, you may have made some manual changes to these ASP configuration files. You may also have made changes to generated source code outside of the prescribed begin/end application code blocks. The process of generating code will overwrite these changes. The IDE provides you an opportunity to backup these files before they are overwritten during code generation. Depending on your project settings you may see the following dialog.

Yes: Backs up the existing source and configuration files into the directory specified and then proceeds with code generation.

No: Proceeds with code generation without backing up the source and configuration files.

Cancel: Stops code generation without making any changes.

Never show this dialog again: Selecting this check-box will persist the selection made with the Yes or No buttons as a project property and always use this option when generating source code.

Only one backup version of a project’s directory directory is maintained.

If you have selected Never show this dialog again but want to now change the backup mode you can do this through the Project Property dialog. See the section Setting Project Properties.

12.1 Merging User Application Code

When you generate the code for the model which already has the user code, IDE will find the diff for generated code with existing user code and display the list of modified files in the Merge window.

Merge: Select files in the list and click Merge button. All user code placed within the following blocks will be moved into the newly generated code.

---BEGIN_APPLICATION_CODE---

---END_APPLICATION_CODE---

Override: Select files in the list and click Override button. all user code will be overridden by generated code.

Override All: This will override all the user code.

Always wants to override application code: Select this option if you want to override application code every time.

Always wants to merge application code: Select this option if you want to merge application code every time.

12.2 SNMP auto code genaration

If you have SNMP sub-agent in your model and you want to use SNMP auto code generation, before generating source code you need to enter MIB directories location and module name in SNMP Properties Dialog for SNMP sub-agent component. For more information, see Setting SNMP sub-agent Properties section in Chapter 7, Setting Component Properties.

CHAPTER 13

Building the Project

Building the project takes the generated source code files and uses them to build the project executable file. This executable is located in the target folder in the '<projectarea_directory>/<model_name>/src directory. To build the project select the Project > Build Project menu item. The Build Configuration dialog appears.

Build Configuration Details

Enter the following information:

Use pre build SAFPlus: Select this checkbox to use prebuilt ASP libraries. When checked the field to the right will become enabled. This field holds the location of the pre build SAFPlus libraries. To get more information about pre-building ASP libraries, see OpenClovis SDK User Guide .

With cross build: Select this check box to build the code for another CPU. Also select the CPU from the drop-down list.

This option is only available if you have installed cross-build tool chains during the installation process.

With Kernel build: Select this check box to build the code for another Kernel version. Also, specify the CPU in the text box.

Include SNMP for North Bound Access: Select this checkbox to include SNMP libraries. If you do not include SNMP build, it does not build the SNMP server in ASP and the SNMP agent in the model. If your model has SNMP dependencies, then this should be turned on to compile and link with the installed SNMP utilities.

Include Chassis Manager for HPI Access: Select this checkbox to include Chassis Manager (CM) component. This is used to build ASP for an ATCA environment where there is a Shelf Manager that communicates through the Hardware Platform Interface (HPI).

Select an option from the drop-down menu. The options available are radisys and openhpi.

The Include Chassis Manager for HPI Access checkbox is only enabled if a Platform Support Package is installed within the project’s configured SDK location.

Force Configure: Select this check box to forcefully configure the project before build.

Click OK to build the project.

When complete a build output message is printed on the Console pane at the bottom of the OpenClovis IDE window.

Project building and image generation (explained in the following section) can also be accomplished from the Linux command line. For more information on the command line based process, see the respective sections of the OpenClovis SDK User Guide : Building ASP and ASP-based Systems and Deploying and Running OpenClovis ASP on a Target System.

CHAPTER 14

Making Project Images

Making project images takes the project executable that was created during build project and packages it for deployment in a specific environment. To make the project images select the Project > Make Images menu item. The Make Images Configuration dialog appears with three tabs.

General tab is used to indicate information about the environment on which the images will be deployed. This information is used to tailor the images to run on that environment.

Create Node Specific Images: This check box indicates whether to create node specific images or single image for all nodes.

Package Images into Tarballs: This check box indicates whether to package the images into tarballs.

Node Instance Information: This table contains a row for each node instance that was defined in the model. The values in the rows are used to specify how the node instance will be deployed on the ASP cluster.

1.Node Instance: This read-only field displays the name of the node instance.

2.Slot Number: This value represents the slot in the chassis on which the node instance will run. This field is a drop down list of slot numbers. The values in this list are determined by the ’Number of slots’ field in the Chassis Resource Details dialog in the Resource Editor.

3.Network Interface: This value indicates the port on the target blade that the node instance will use to communicate to other blades in the chassis.

Chassis Management tab is used to indicate how the nodes in the ASP cluster will communicate with the chassis management module if the project has been set to include chassis management for HPI access during the build process.

These fields will be disabled if the project is not configured to include chassis management.

Module IP: This value is the IP address of the target chassis management module. Required if the project is configured to include chassis management.

Authentication Type: This value indicates the method of authentication that will be used when logging into the chassis management module. This field contains a drop-down list of values.

Username: This value represents the user name of the acount that will be used when logging into the chassis management module.

Password:This value represents the password of the acount that will be used when logging into the chassis management module.

3rdParty tab is used to add bin and lib files for the 3rd party components. These added files will be included in final images.

These controls be only enabled if a component in the model has been configured as a 3rd party component.

Add Bins...: This control is used to add 3rd party component’s binary files.

Delete Bins: This control is used remove the binary files from existing List.

Add Libs...: This control is used to add 3rd party component’s library files.

Delete Libs: This control is used remove the library files from existing List.

TIPC Specific: Inter process communication

Trap IP: This value specifies where the SNMP sub-agent will send traps at runtime. This field is optional but if specified must be a valid IP address.

TIPC Net ID: This value represents a unique identifier used by TIPC to set up interprocess communication across the deployed OpenClovis ASP cluster. This is an unsigned 32-bit integer, and should be unique for every model that is deployed. This will allow multiple models/clusters to run within the same network LAN without interference.

UDP Specific: This Provides Transport Layer Facility

Image generation can also be accomplished from the Linux command line. For more information on the command line based process, see the section Deploying and Running OpenClovis ASP on a Target System in OpenClovis SDK User Guide

CHAPTER 15

XML Representation of the Model

The OpenClovis IDE helps you to build the Clovis Information Model (IM) and subsequently generate code and configuration files. The information required by the IDE is stored in well-defined XML files which conform to a published schema. This document describes the organization and content of these XML files which are part of the OpenClovis project that can be read by the IDE. This document along with the XML schemas should provide you with the insight into creating a project and populating the corresponding XML files.

Key Topics :

Overview

File Organization

File Specification

This document does not describe the individual XML attributes/elements that go into the files. For information about the configurable fields, refer to the relevant chapters within this guide.

15.1 Overview

The Model for an IDE project is stored in XML files in an open and well-defined format. The OpenClovis IDE is able to import any project model that conforms to the schema and organization of the project files as described in this chapter. These files can be generated by you using any tool of your choice and you can subsequently import and manipulate the project through the IDE.

It is your responsibility to ensure that the information contained in the files is consistent and valid. There should not be any incorrect references or erroneous information in the files as this will lead to incorrect behavior of the IDE as well as failure to import the model.

The schema for all the project XML files is also provided in .xsd form with comments to help you in creating the XML files.

If you need to store your project in the version control system (example, SCM), the complete project workspace directory has to be stored. The relevant project XML files are explained in the later part of this chapter.

15.2 File Organization

The organization of the set of project files for each individual project must be as shown in Figure Directory Organization.

If you have used another tool to create the project, you need to import your project into OpenClovis IDE.

Directory Organization

The information is provided in different files in different directories as illustrated in Figure Directory Organization.

CHAPTER 20

Glossary of Terms

Alarm An alarm is a warning about the abnormal conditions of Managed Object (MO).

An alarm always does not represent an error.

Alarm Lifecycle The Alarm Managed Service Object (MSO) associated with an MO depicts the lifecycle of an alarm as:

An alarm is raised by the alarm service, if the abnormal condition relating to the alarm persists for a time, at least equal to the soaking interval specified. This alarm may be cleared by:

1.The alarm service, when it gets a notification from the MO that the abnormal condition which caused the alarm has been cleared.

2.An explicit command from an operator using the management interface.

3.RESET, if the MO is hardware, and RESTART, if the MO is software Execution Object (EO).

Alarm Manager The alarm manager enables configuring and handling of alarms. It provides support for alarm soaking, masking, alarm hierarchies, retrieving previous alarm conditions, and correlation of the alarms before publishing.

Alarm Masking Multiple alarms can be raised in a system. Alarm-masking is a procedure that enables the alarm service to publish the alarms with high priority for fault recovery.The current alarm-masking logic implies that all MOs are organized in a fault containment hierarchy which represents the relationship "is physically contained in" for hardware and "runs on" for software. The alarm-masking algorithm masks all alarms of the same or lesser severity level within any sub-tree in the hierarchy.

Alarm Service The OpenClovis alarm service implements a generic engine to process abnormal conditions reported by managed resources. The process includes identifying the alarm type and its severity level and determining whether an alarm has to be raised after running it through soaking and masking procedures.Potential subscribers for alarm events are - OpenClovis Fault Management Service, OpenClovis Availability Management Service and other agents like SNMP, CLI, and so on for reporting alarms to external managers.

Alarm Severity The alarm severity specifies the condition of the service provided by the MO. The severity levels can be critical, major, minor, warning, or cleared and indeterminate (CCITT X.733). The cleared and indeterminate level indicates clearing of one or more previously reported alarms. The critical and major alarms are service-affecting alarms.

Alarm Soaking Soaking is the time defined for extreme conditions before reporting as an alarm. Alarm soaking is possible when a managed resource provides a pair of notifications - one for the occurrence of an extreme condition and another for clearing of the extreme condition. Soaking avoids raising an alarm unless the extreme condition of the alarm persists for a period of time. Sometimes, you may not get a notification for clearing of an extreme condition. In such cases, a poll mechanism can be used to see if the alarm condition is still present after the soaking interval.

Application An Application is customer software built using OpenClovis infrastructure that provides services to the end users. For instance: A SIP server customer application.

ASP Console A command-line Interface for debugging allows access to the managed object repository for creating, deleting and otherwise manipulating objects. ASP Console also provides viewers for system log and trace data as well as interfaces to individual EOs to view and modify their private (non-persistent) data.

Attributes Attributes are the characteristics or parameters of a Managed Object.

Availability Management Framework (AMF) AMF is a software entity that provides a framework for high availability of applications in a system. It is responsible for instantiating and managing all the OpenClovis ASP services. It executes configured recovery actions on the failure of application components. The AMF is built with the close association of two OpenClovis ASP components: Component Manager and the Availability Management Service (AMS).

Blade A blade is a single board computer that is a Field Replaceable Unit (FRU). It can be plugged into a chassy.

Boot Level OpenClovis ASP services and customer applications are mapped to different Boot Levels. The Boot Management Service starts these services (applications) when it reaches the specified BOOT LEVEL. The BMS can be constrained to boot-up only to a specified BOOT LEVEL.

BOOT_LEVEL is conceptually similar to the run_level concept in Unix.

Boot Management Service OpenClovis Boot Management Service provides the support for starting or shutting down of the OpenClovis ASP services and customer applications on a OpenClovis ASP managed platform. The Boot service assumes that an OS has already been booted-up in the target environment. While starting or shutting down a system, the BMS has several BOOT LEVELS in sequence. At each level, certain services (applications) are started or shutdown.

Boot Profile The boot profile defines a particular type or a particular mode of boot configuration. The list of services performed can be different for different profiles. This helps in obtaining different configurations containing different set of boot levels and different Service Units assigned to them.For Instance, a profile named debug can define a boot configuration, which can be helpful in debugging the boot up process, whereas a profile named production can be used when the desired configuration for normal deployment boot needs to be specified.

Chassis Management Service OpenClovis Chassis Management Service provides support for resource discovery, sensors, and controls on chassis-based hardware platforms. The platforms can be standard-based (ATCA, BladeCenter and so on) or proprietary. The Chassis Management Service can be customized for any platform by providing the platform specific plug-ins.

Checkpoint Service (CPS) CPS provides synchronization of run-time data and context to ensure a seamless failover or switchover of applications. It allows the application to store its internal state and retrieve the information. It also provides a facility for processes to record checkpoint data incrementally and supports nontransparent mode of Checkpointing.

Clovis Object Repository (COR) Clovis Object Repository (COR) is an inmemory object-oriented hierarchical distributed repository of Managed Objects (MO). COR contains the description of each MO and relationships between different MOs. Multiple relationships - hierarchical containment and inheritance - are supported. COR provides Object lifecycle management, transactions on multiple objects, object change notification, object change propagation and other services. The OpenClovis ASP instances on the System Directors has an instance of the Clovis Object Repository associated with it. The CORs on both the System Directors are always in-sync to provide high availability.

Cluster A cluster is a collection of cluster nodes that may change dynamically as nodes join or leave the cluster.

Cluster Node A cluster node is the logical representation of a physical node.

Component A component is the logical entity that represents a set of resources to the Availability Management Framework. The resources represented by the component encapsulate specific application functionality. This set can include hardware resources, software resources or a combination of the two.A component is the smallest logical entity on which the Availability Management Framework performs error detection and isolation, recovery, and repair.

Configuration Attributes Configuration attributes are the means by which system management applications provide input on the desired sets of attributes and their handling that an Object Implementer (OI) should implement.

COR Persistence The Clovis Object Repository may be persisted using a persistent database. The effect of this is as follows: When a OpenClovis ASP instance boots up, COR reads the database and restores the persisted state to each MO. This state is used, for example, by the provisioning service to provision all objects on boot-up.

DBAL Provides a standard interface for any OpenClovis ASP infrastructure component or application to interface with the commonly used relational. DBAL currently supports GNU Database Manager.

Default Boot Level During startup, the Component Manager boots the components to a boot level called default boot level as specified in the deployment configuration file. All the components specified up to and including the default boot level are started.

EO Management service The OpenClovis Execution Object (EO) Management Service monitors the health and controls the state of all Execution Objects in the system. State control includes the ability to start, stop, suspend, resume, kill and restart an EO.

EOID Identifier for execution object (EOID is unique within a OpenClovis ASP instance).

Error Error is the deviation in the system state or behavior as a result of the use of incorrect data or signal.

Erroneous Condition A condition which the application needs to notify the north bound entity.

Event Events are means by which data may be exchanged between event publishers and event subscribers. An event is characterized by an event channel and event ID.

Event Filter These are filters used by an EO to specify the events it is interested in.

Event Manager The Event Manager provides a distributed service infrastructure for event notification across multiple blades. It is based on the publisher subscriber programming model, which decouples senders and receivers both in space and time. An event dispatcher resides on each node, which handles local subscriptions and forwards all events to the respective clients and all peer event dispatchers.

Event publisher An EO that publishes an event.

Event Service A OpenClovis ASP service that provides a mechanism to publish or subscribe communication based on event channels and asynchronous communication between publishers and subscribers.

Execution Object The motivation for the OpenClovis EO is to provide execution contexts independent of process architecture in any OS.Execution objects are programs that implement management interfaces (mandated by OpenClovis ASP).

These programs allow them to be managed in a OpenClovis ASP environment. (Refer to EO Management Service, for details of management functions).EOs may use services provided by other EOs (For example, Checkpointing service). If so, they need to implement client interfaces for the service in question.EOs may provide services to other EOs. In this case they need to implement the service interface.EOs may be made visible to an external manager by representing them as MOs.

Failure A failure in a system occurs when the consumer (human or non-human) of a service is affected by the fact that the system has not delivered the expected service. It is a reflection of unacceptable or incorrect results delivered by a system with respect to a specification. It is an unexpected behavior perceived by the consumer or user of a service. Fault A fault is a Physical or algorithmic cause of a malfunction. Faults manifest themselves as errors.

Fault Diagnosis Fault Diagnosis is the process of determining the cause of a fault. Fault diagnosis is provided to the granularity of an FRU to support maintainability or serviceability. Fault Management Service OpenClovis FMS provides a framework for fault management, including fault diagnosis and progressive recovery. Standard recovery methods for software exceptions are available. You can plug-in custom fault recovery methods.

Fault Manager The Fault Manager manages faults in a system and initiates actions. It can handle various user-defined run-time faults, including hardware and software faults. It can prioritize faults to ensure that the critical faults are addressed before the normal or the low-priority faults.The Fault Manager client library notifies alarms to the Fault Manager server located on the same node. The actions to be taken on receiving a fault are controlled by the FM policy associated with the faults.

Field Replaceable Unit (FRU) Field Replaceable Unit is the hardware element of a system that can be replaced by a similar element in the field.

Group Membership Service (GMS) Group membership service provides the facility of leader election. Any application or OpenClovis ASP service can register with GMS to keep track of information such as leader change and cluster membership change.

Hardware Abstraction Layer (HAL) Provides a uniform management interface to hardware peripheral devices via their respective device drivers. Device types include Framer, NP, ASIC, LIU, Switch chip, DSP, and so on. HAL supports the following interfaces: Access, Init, Open, Close, Control, Retrieve, Send, Receive, Download OpenClovis ASP. Customer applications are made entirely transparent to configuration changes in the underlying devices by the HAL.

Hardware Resource A hardware resource is a MO class corresponding to hardware objects present on the blade (example, port). Hardware resource can be within another hardware resource. For example, port on a blade.

Heartbeat Heartbeat is a message exchanged at regular intervals between two OpenClovis ASP instances. A missed heartbeat is the non-arrival of a heartbeat within a timeout period. A configurable number of missed heartbeats are taken to indicate that one of the two instances in question is no longer running or is incommunicable.

Heartbeat Service A service that runs on every OpenClovis ASP instance and monitors the health of other OpenClovis ASP instances using the heartbeats.

High Availability (HA) High Availability (HA) is used when referring to a system that is capable of providing service most of the time.

Intelligent Object Communication (IOC) OpenClovis Intelligent Object Communication (IOC) provides a transport and OS neutral, fault tolerant communication between OpenClovis Execution Objects using physical links available and user defined transports (E.g.: UDP, TCP, or Ethernet).

Interface Definition Language (IDL) IDL is a library used by all EOs to communicate efficiently across nodes. Using IDL, OpenClovis ASP services can communicate across endian machines and mixed mode (32-bit and 64-bit architecture).

IOC Address Address of a OpenClovis ASP (IOC) instance that maps to a transport address for each transport or physical link provided.

Link A link is a physical interconnection between nodes. Also referred to as physical medium.

Local Managed Object A managed object abstracting a local resource.

Local Resource A resource that is contained from a fault-containment point of view within a physical node. (Local resources can be software abstractions implemented by programs running on the node, or hardware attached to the node, or the node itself)

The definition is SA Forum defined.

Log service Log service collects, translates, and publishes log messages to record any significant event in the system. For example, operational state change of a component, managed object attribute value change, and so on.

Managed Object (MO) Managed Object provides an abstraction for the manageable properties of a resource in the system. MOs have attributes, support management operations, exhibit behavior and can emit notifications (CCITT X.700).Operations on an MO can be Create or Delete Instances; Get or Modify attributes; Action.Notifications emitted by an MO instance are instance created/deleted; report attribute change; class specific notification such as alarms.Attributes can be single valued, multivalued or grouped in an attribute group (Ex; Chassis attributes relating to blades may be grouped).

Managed Service Managed Services are the services or capabilities that are available within an MO, and provided either by MO, or by an MSP, which is a member of the MO. An MSP is an execution context that hosts the Managed Service and processes the service request.For example, the Blade MO can provide Configuration, Fault, and Performance Managed Services. And, the actual MSPs can be the Provision/Configuration Manager, Fault manager and Performance manager respectively. Managed Services include FCAPS (Fault, Configuration, Accounting, Performance, and Security), and other services such as Heartbeat and HA service.

Managed Service Object (MSO) MSOs encapsulate the attributes of a Managed Object specific to the particular service (MSP) they are associated with. (Ex: Alarm severity is an attribute related to the alarm service; it is a part of the Alarm MSO associated with any MO desiring an alarm service).

Managed Service Provider (MSP) The execution context that provides a managed service to an object is called the Managed Service Provider (MSP).The lifecycle of managed objects (creation, deletion...) is handled in the execution context of the COR EO. However, when an MO state is to be changed, the MSP interested in this change runs (prevalidate, update, post-validate) methods in a different execution context.

Management Information Base (MIB) Management Information Base is a data structure that holds information on how a system is configured or functioning.

Management Interfaces Methods available for managing a system at the boundary of the system and management middleware. In OpenClovis ASP, management interfaces (for different management protocols) are provided by the Mediation manager.

Mediation Library The Mediation Library mediates between management agents implementing standard protocols (such as CISCO CLI or SNMP) and the OpenClovis ASP to service management requests from respective (CLI, SNMP) management stations. Requests from outside the system are translated to requests on MOs and forwarded to the appropriate MO.

Message A message is a byte array of a certain size. In addition to the data contained in the byte array, a message also has a type, version, and priority.

Message Queue A message queue is a software abstraction for buffering messages. A message queue consists of a collection of separate data areas that are used to store messages of different priorities. Messages are read from, and written to, a message queue.

Message Queue Group A message queue group is a collection of message queues that are addressed as a single entity. A message queue group is global to a cluster, and it is identified by a unique name in the same name space used for the names of message queues. A message queue can be a member of different message queue groups. Messages sent to a message queue group are directed to one or more of the message queues in the group.

Middleware OpenClovis ASP is often referred to as a middleware. This is to reflect that OpenClovis ASP is a layer over the OS, providing system services and APIs to user applications. Applications must be written to OpenClovis ASP API’s (rather than directly to OS API’s) in order to be OS, database and hardware independent and to be manageable and available.

MO (Instance) Tree Managed Object Instance Naming Tree - The MO fault containment hierarchy (see OpenClovis Information Model) is used to name instances of objects. For example, in a chassis based system, an instance of a port could be located as follows: Chassis (0)/Blade (3)/Port (2).

MOID Managed Object Identifier - The MOs have unique global handles associated with them within the system, and using these handles one can address the MOs. The COR handle uses a pair of object class index and object instance index. Object class index uniquely identifies a managed object class and managed object instance index uniquely identifies an instance of a managed object within that class.

Name Service The name service facilitates location transparency to the communicating objects by allowing use of object name instead of location specific address. The name service provides name to IOC address translation. A name is userdefined data.

Node A node is a blade, a stand-alone PC, or a daughter card that runs the AIS services and can become a member of the cluster.

Node Class The following types of node class are available:

SAF Class A: System Controller: These cards act as chassis managers or system controllers, and are either standalone or run only OpenClovis controller functions. Customer applications will typically not run on a Class-A card as the intent is to keep them stable and working in a system over a long interval. The Class-A cards are the primary physical link for any external management entity such as EMS. A Class-A blade can assume access to persistent storage on the blade or within the system.

SAF Class B: System Controller: There are two subtypes within this profile. They are Class-B1 and Class-B2. Class-B1 cards support only OpenClovis master functions. OpenClovis controller functions are located on a separate Class-A card. Class-B2 cards contain both master and controller functions and there is no separate Class-A card in the system. Class B1 blades may or may not have access to local persistent storage and hence must not assume the same while Class-B2 cards may assume access to local persistent storage. Class-B cards may also contain application functions.

SAF Class C: Payload: This actually defines a set of card profiles, each of which can contain a different set of OpenClovis functions. However, the common link between all is that they cannot have OpenClovis master or controller functions and are only participants in a OpenClovis system. Class-C blades may or may not have local persistent storage and hence must not assume the same.

SAF Class D: Non-ASP Node: OpenClovis is aware of these blades in the system and must manage them, whereas no OpenClovis components run on this blade.

Node Profile Node Profile describes the list of services that can be run on this node and the various attributes of these services. It also describes the characteristics of the node with respect to its role in the chassis. A node can either behave as a Controller Node for the complete chassis or as a normal processing node in the chassis.

Notification Managed Objects emit notifications. Notifications emitted by an MO instance are instance created/ deleted; report attribute-change; class-specific notification such as Alarm (Also referred to as COR notification).

OAMP Refers to Operations, Administration, Maintenance and Provisioning.

Object Implementer Services and applications that implement the Information Model Management (IMM) objects are called Object Implementers.

Object Manager Object Manager (OM) is a library which provides some of the object oriented features like inheritance and function overriding to be used by OpenClovis ASP services or user applications in C language. Using Object Manager library one can create a class, which has data members and member functions. A base class can be inherited to form a derived class. The derived class has data members as well as the member functions of the base class. The functions can be overridden in the derived class. Object manager library provides functionality to create such base classes, derived classes and create instances of such classes. The object manager library also provides APIs to maintain association between these OM objects and COR objects.

OM Objects Managed Objects encapsulate data and behavior (have attributes and methods). The public attributes of an MO associated with a specific (service) capability of the managed object are segregated into MSOs. Behavior and private data associated with the capability is encapsulated in a corresponding OM Object.While the MO and the MSOs are persistent in the COR database, associated OM Objects are created by the interested MSPs and follow the MSP lifecycle. (For example, if the alarm service is brought down for some reason, the Alarm OM objects will also be deleted).

OpenClovis ASP Services OpenClovis ASP services are Execution Objects that provide core-underlying services for OpenClovis ASP and applications.

OpenClovis IDE This Is a Graphical User Interface (GUI) tool designed to simplify and accelerate the development of System Infrastructure Software for Telecom and other networking products. It enables the customer to rapidly create an information model of the Resources that will be required to manage. It generates customized code for OpenClovis ASP, a flagship product of OpenClovis Inc.The OpenClovis IDE is built on the Eclipse Modeling Framework (EMF). It provides two important features: Modeling and Configuration. It allows you to model the following elements: Physical Resources and Logical Entities.

OpenClovis Information Model The OpenClovis Information Model (IM) is a generic framework or an abstract representation of the entities in a managed environment. It provides a way of describing the characteristics of the network element for which the infrastructure software is being implemented. IM provides a unified view and association of all the physical and logical objects in the managed environment. Information Modeling transports the current content or state of a OpenClovis Object such as a blade, port, or any other logical object between different Execution Objects.

Operating System Abstraction Layer (OSAL) The OpenClovis Operating System Abstraction Layer provides commonly used APIs to abstract OS services for OpenClovis EOs and customer applications.The basic OS services include the following:

Memory Management, Timer Management, Executive Task/Process/thread Management, Signal/Event Management, Resource Management, Messaging services, RTOS task profiling services, synchronization and semaphore management.

OSAL enables one to easily port the OpenClovis ASP and OpenClovis ASPenabled customer applications onto new RTOS environments.

Physical Node A physical node is a particular type of resource that can run a single instance of the operating system and OpenClovis ASP software. (Example, a blade with a general purpose CPU). Physical nodes may be interconnected via some form of communication medium (Example, multiple blades via a chassis backplane).

This is consistent with SA Forum definition Process Model. The process model describes how OpenClovis ASP service EO’s and user application EO’s map to processes in a specific operating system. (Example: in the multi-process version of Release 1.0 for Linux, all OpenClovis ASP EOs run in a single Unix process and user application EOs may be combined in one or more processes).

Pre-provisioning Normally, the provisioning of an object corresponding to an FRU occurs when that FRU is present. However, pre-provisioning takes place when an MO exists and the FRU is absent. Scenarios where this occurs:

A blade lost power or was extracted from the chassis after being provisioned.

A user pre-provisioned a blade in the Provision Manager’s database in the absence of a blade.

When the blade becomes active, the provisioning service on the System Controller verifies the provisioned data against the properties of the blade and pushes the data down to the blade if the blade’s properties match; otherwise, an identity mismatch alarm will be raised and no data will be pushed down.

Provisioning Service The Provisioning service is an Engine that provisions any type of equipment and facility, virtual or physical in the most generic way. Provisioning is accomplished using the Provisioning EOs and provisioning MSOs.

Reboot Cold reboot occurs when a system is powered off and then powered on. In a warm reboot, the hardware remains powered on and provisioning is not disturbed; the OS is re-started.

Remote Method Dispatch Remote Method Dispatch is the foundation for all OpenClovis ASP client APIs. It implements remote procedure call semantics using both synchronous and asynchronous methods.

Resource A resource is any entity that can be managed by the OpenClovis ASP. A resource is either hardware equipment (for example, a blade) or a software abstraction implemented by programs running on that hardware (for example, a software process).

The OpenClovis resource definition corresponds to the SA Forum definition of resource.

Routing Table Based on the information in this table, IOC module selects a transport and the next IOC hop, to send a message towards its destination. Multiple routes (to the same destination) are required for fault tolerance.

Rule-Based Engine (RBE) Rule-Based Engine (RBE) provides a mechanism to create rules to be applied to the system instance databased on simple expressions. An expression consists of a mask and a value. These expressions are evaluated on user data and generate a boolean value for the decision.

Run Level Mechanism used to synchronize and order the execution of EOs within and across different OpenClovis ASP instances.OpenClovis EOs are configured to execute at some run-level; therefore, they can be controlled by the Boot Manager’s Run-Level Controller (RLC). For example, the Alarm Agent is configured at Level-2 after the Provisioning Agent, which is at Level 1. This implies that the Alarm Agent has some execution dependency on the Provisioning Agent and that there is some critical section in the Provisioning Agent’s initialization code that needs to execute first before the Alarm Agent can continue its execution.

Runtime Attributes Runtime attributes are the means by which Object Implementer (OI) reflect the current state of the attribute they implement in the information model. Run-time attributes are typically under the control of Object Implementer's.

SA-Aware Component An SA-aware component is a local component that supports the SA functionality provided by the Availability Management Framework and are under direct control of the Availability Management Framework. The Availability Management Framework directs operations to the component as to what it should do and when to do it. The component then reacts appropriately to these operations.

Service Service is the output of a system that meets the specification for which the system is devised.

Service ID Uniquely references a service (OpenClovis ASP or customer designed). Shelf It is a structure/frame where one or more chassis are mounted.

Simple Network Management Protocol (SNMP) Simple Network Management Protocol (SNMP) is a sub-agent, which provides the flexibility to manage platform and non-platform hardware, the OpenClovis ASP model, and the alarms present in the system. Using SNMP, you can manage the attributes of an MO that includes run a get, set, or notification.

Software Resource A software abstraction implemented by programs running on a hardware resource (example, a software process) is called a software resource.

System The system consists of a collection of physical nodes and programs running on those nodes (Ex: A chassis with multiple blades and running software programs).

System Log A persistent file that records the significant events occurring in the system. Typical entries include events related to boot-up, shutdown, errors, recovery, operator commands, operator log-on and log-off. Each log entry contains a timestamp, reporting entity, affected entity, and severity code and operator identity (if applicable).

Transaction Manager Transaction Manager provides a library for resource managers to use transaction semantics to manage distributed data. Any component, that needs to be part of transactions can link with this library and act as a resource manager. The transaction manager automatically tracks participants and provides ACID semantics to ensure that all participants are updated properly, or will rollback to previous state assuring data integrity despite component failures.

Transactions OpenClovis ASP supports transactions in the following sense:

Any service that changes the state of managed objects may provide three methods: pre-validate (), update () and post-validate (). All these methods must be successfully executed for the transaction to be complete. The affected MO state is also updated in the persistent COR database as part of the transaction. (Rollback is currently not supported).

OpenClovis ASP also supports nested transactions. A list of EOs (called station list) may be associated with each MO/MSO. Each EO in the list may provide the three methods listed above. The nested transaction is implemented as follows: The list is traversed top down and the pre-validate method of each successive EO is executed. When the last EO in the list is reached, the update and post validate methods of that EO are executed and now control returns to successive EO’s up the list with the update and post methods being executed in each case. The transaction is considered successful if no error is reported by any method executed as part of the transaction.

Transport OpenClovis term for user (system developer) provided communication facility, which provides IOC access to the physical medium.
