Before you begin
About this task
A queue manager can make a fresh start in a cluster. In
normal circumstances, you do not need to use the REFRESH CLUSTER
command.
Procedure
REFRESH CLUSTER
MQSC command
from a queue manager to remove auto-defined cluster queue-manager
and queue objects from the local repository. The command only removes objects that refer to other queue managers, it does not remove objects relating to the local queue manager. The command also removes auto-defined channels. It removes channels that do not have messages on the cluster transmission queue and are not attached to a full repository queue manager.
Results
Effectively, the REFRESH CLUSTER
command
allows a queue manager to be cold-started with respect to its full
repository content. IBM WebSphere® MQ
ensures that no data is lost from your queues.
