Targeting the JMS Server to a Migratable Target

JMS-related services are hosted on individual server instances within a cluster and for these services, the WebLogic Server migration framework supports failure recovery with service migration, as opposed to failover. In a clustered server environment, a recommended best practice is to target the JMS server to a migratable target, so that a member server will not be a single point of failure. Therefore, the following prerequisite instruction is required if configuring The WebLogic Message Queue In A Cluster.

Note:

The instruction below assumes the WebLogic domain being configured has managed servers already created and assigned to a cluster parameter.

1. Launch the WebLogic Remote Console.
2. Configure the cluster migration basis to Consensus.
   1. In the NavStrip, click Edit Tree.
   2. In the Navigation Tree, expand Environment, expand Clusters, then click the cluster you created in your WebLogic domain.
   3. In the Content Pane, click Migration.
   4. On the Migration Basis list, select Consensus.
   5. Click Save.
3. Configure a migratable target for a managed server in the cluster:
   1. In the NavStrip, click Edit Tree.
   2. In the Navigation Tree, expand Environment, expand Migratable Targets, then click a managed server assigned to your cluster.
   3. In the Content Pane, click the General tab.
   4. On the Service Migration Policy list, select exactly-once.
   5. Click Save.
   6. Click the Migration tab.
   7. In the Constrained Candidate Servers section, select the servers and additional managed servers in the cluster you want to support failure recovery and click addToChosen.
   8. Click Save.
4. Click Click to view shopping cart actions, and select Commit Changes.
5. Restart the Admin server and the managed servers in the cluster for changes to take effect.
