Configuring messaging engine failover for mixed version clusters

A messaging engine that is hosted on a WebSphere® Application Server Version 7.0 server cannot fail over to a messaging engine that is hosted on a WebSphere Application Server Version 6 server. If you have a cluster bus member that consists of a mixture of Version 6 and Version 7.0 servers, you must make sure the high availability policy is configured to prevent this type of failover.

About this task

To prevent failover of a Version 7.0 messaging engine to a Version 6 server, configure the high availability policy for the messaging engine so that the cluster is effectively divided into one set of servers for Version 6 and another set of servers for Version 7.0, and the Version 7.0 messaging engine is restricted to the servers at Version 7.0.

Procedure

Make sure that the high availability policy is configured to prevent Version 7.0 messaging engines from failing over to messaging engines hosted on a Version 6 server. For information about configuring messaging engines for high availability see Configuring high availability and workload sharing of service integration.
