The following topic provides information about JMS resource adapter behavior during WebLogic Server service migration.
If a WebLogic JMS server is configured to use a migratable target, a JMS resource adapter instance reconnects to the migrated WebLogic JMS service after a service migration is completed.
Note:
WebLogic JMS service migration provides high availability for JMS services, but it does not provide load balancing.
See Migratable Services in Administering Clusters for Oracle WebLogic Server for more information.
Note the following details regarding how the JMS resource adapter handles inbound and outbound communication during JMS service migration:
Inbound communication
During JMS service migration, the JMS resource adapter closes existing WebLogic JMS connections and sessions. New connections and sessions are created that point to WebLogic Server instance where the JMS server and its distributed destination members have migrated.
Outbound communication
During JMS service migration, the distributed destination members of a failed WebLogic Server instance are migrated to an available WebLogic Server instance.The WebLogic JMS client associated with the JMS resource adapter detects the migration and redirects JMS operations to the new migrated destination members.
