From Model

Step 1

- Using IDE open your model, upgrade your model, a xport configure file clTransport.xml will be generated in <your model>/config/clTransport.xml

   <?xml version="1.0" encoding="UTF-8"?>
   <openClovisAsp>
     <version v0="4.0.0">
       <multixport xmlns="multixport.ecore">
        <config>
          <default>TIPC</default>
        </config>
         <xports>
           <xport>
             <type>TIPC</type>
             <plugin>libClTIPC.so</plugin>
           </xport>
         </xports>
       </multixport>
     </version>
   </openClovisAsp>

Step 2

Edit content clTransport.xml with UDP default:

   <?xml version="1.0" encoding="UTF-8"?>
   <openClovisAsp>
     <version v0="4.0.0">
      <multixport xmlns="multixport.ecore">
         <xports>
           <xport>
             <type>UDP</type>
             <plugin>libClUDP.so</plugin>
           </xport>
         </xports>
         <multicast address="226.0.1.1" port="9595" />
         <heartbeat>
             <interval>3000</interval>
             <intervalLocal>3000</intervalLocal>
             <retries>5</retries>
         </heartbeat>
       </multixport>
     </version>
   <openClovisAsp>

UDP use multicast to notification component arrival and departure.

Step 3

Add 2 env variables into <model_dir>/src/target.env:

export ASP_UDP_SUBNET=<IP Range>/Length
export ASP_UDP_LINK_NAME=<your interface>

• Example:

export ASP_UDP_SUBNET=192.168.57.0/24
export ASP_UDP_LINK_NAME=eth0

Step 4

Before running ASP, should export/setenv 2 below variables:

export ASP_UDP_SUBNET=192.168.57.0/24 
export ASP_UDP_LINK_NAME=eth0

UDP without Auto IP address assignment

To use the UDP transport with the IP address, 'already configured' on a link, set these variables in your environment before starting SAFplus:

ASP_UDP_USE_EXISTING_IP=true
ASP_UDP_LINK_NAME=<link name, for example 'eth0'>

clTransport.xml should add static IP addresses for cluster:

    <peerAddresses port="6789">
       <peer addr="192.168.56.101" slot="1"/>
       <peer addr="192.168.56.102" slot="2"/>
    </peerAddresses>

UDP without Node Discovery (Multicast)

To use the UDP transport without node discovery, you must explicitly configure the static addresses and define variable environments ASP_UDP_USE_EXISTING_IP=true and ASP_UDP_LINK_NAME for getting ip addresses below.

<?xml version="1.0" encoding="UTF-8"?>
<openClovisAsp>
 <version v0="4.0.0">
   <multixport xmlns="multixport.ecore">
     <xports>
       <xport>
         <type>UDP</type>
         <plugin>libClUDP.so</plugin>
       </xport>
     </xports>
    <heartbeat>
         <interval>1000</interval>
         <intervalLocal>1000</intervalLocal>
         <retries>4</retries>
    </heartbeat>
    <peerAddresses port="6789">
       <peer addr="192.168.56.101" slot="1"/>
       <peer addr="192.168.56.102" slot="2"/>
    </peerAddresses>
   </multixport>
 </version>
</openClovisAsp>

From Image

Create a clTransport.xml like step 2 & 3 above and retarball your images.

Q&A

• Q: Is the SAFplus able to run as a user other than root?
• A: Only pre-requisites, configure interface name (ASP_UDP_LINK_NAME) with IP address (ASP_UDP_SUBNET.DEFAULT_NODEADDR) (Use DEFAULT_NODEADDR settings from asp.conf file)

Example:
 root:#ifconfig eth0 192.168.57.1
 user:#export ASP_UDP_SUBNET=192.168.57.0/24
 user:#export ASP_UDP_LINK_NAME=eth0
 user:#./etc/init.d/safplus start
