Stop and restart each queue manager in the queue-sharing group in turn
to disconnect WebSphere MQ and DB2(R) from the structure and delete information about it.
(You do not need to stop all the queue managers at once; just one at a time.)
Remove the structure definition from your CFRM policy data set and run
the IXCMIAPU utility. (This is the reverse of customization task 10 (set up
the Coupling Facility) described in the WebSphere MQ for z/OS System Setup Guide.)
