If there is a core group policy that is associated with a cluster, but that is not associated with any messaging engine in the cluster, and you are using messaging engine policy assistance, you can identify and delete that policy.
Use this procedure when you are creating or maintaining a cluster bus member and messaging engine policy assistance is enabled, but there are warning messages that a core group policy is redundant. This message indicates that the core group policy is associated with a cluster through its match criteria, but it is not associated with any messaging engine that is currently in the cluster.
When you use messaging engine policy assistance, the required associations are created automatically and you do not have to create or manage core group policies directly. A redundant core group policy might occur if messaging engine policy assistance is disabled and you remove a messaging engine without deleting its associated core group policy, or create a core group policy that is not associated with a messaging engine.
