How you route work items for a high availability resource to a different application server during runtime depends on how your application server environment is configured.
Why and when to perform this task
You might need to perform this task if you have to change the application server that is handling work items for a high availability resource, such as the service integration bus. For example, if a core group includes a cluster of application servers, and a messaging engine is configured for that cluster, any of the servers in that cluster can handle work items for the messaging engine. However, if the high availability group with which the messaging engine is associated is governed by a One of N policy, only one of these application servers can be active at a given point in time.If you are using the WebSphere Application Server default configuration for a high availability environment, you can change the application server that is handling the work items for a high availability resource. This change can be performed as a run-time operation (the change exists only in memory) or it can be done as a permanent configuration change. To make this change a permanent configuration change, perform one of the following steps:
Steps for this task
For example, to change which server is handling the work items for the service integration bus, create a preferred servers list for the Default SIBus Policy, which is the default policy for the service integration bus high availability group.
For example, to move a messaging engine, create a new policy for the messaging engine high availability group that has Static as the policy type. The match criteria for this policy must include at least two of the properties that are contained in that high availability group name. The two property match will cause the new policy to be used instead of the default policy for this group.
IBM_hc=AcceptanceCluster,WSAF_SIB_BUS=SSS_Bus,WSAF_SIB_MESSAGING_ENGINE=AcceptanceCluster.000-SSS_Bus,temp_property=WSAF_TEMP,type=jms
WSAF_SIB_MESSAGING_ENGINE=AcceptanceCluster.000-SSS_Bus type=jms
Result
New work items for the high availability group are now routed to a different server.
