A queue manager can make a fresh start in a cluster. This is unlikely to be necessary in normal circumstances but you might be asked to do this by your IBM Support Center. You can issue the"REFRESH CLUSTER" command from a queue manager to remove all cluster queue-manager objects and all cluster queue objects relating to queue managers other than the local one, from the local full repository. The command also removes any auto-defined channels that do not have messages on the cluster transmission queue and that are not attached to a full repository queue manager. Effectively, the REFRESH CLUSTER command allows a queue manager to be cold started with respect to its full repository content. (WebSphere MQ ensures that no data is lost from your queues).
