14 JPA and OBAPI multi-cluster

In a multi-cluster environment, below JPA related changes should be implemented

• Go to Weblogic server
• Open config\META-INF\persistence.xml
• Append below configuration for all data-source

  <property name="eclipselink.cache.coordination.jms.host" value="t3://<WEBLOGIC-HOST-NAME OR IP>:<MANAGED-SERVER-PORT>/" />

  Replace with respective hostname or IP and Port no (this should be the managed server port number which hosts the JPA queues in the cluster)

Key pointers;

• Multi-cluster here refer’s to :
  • Single cluster with multiple nodes (2 or more physical servers hosting the OBAPI product)
  • 2 or more Weblogic cluster’s
• Ensure these (persistence.xml) changes are available to all Managed server by maintaining appropriate classpath
