Removing a Coupling Facility structure

To remove a Coupling Facility structure, follow this procedure:

• Use the following command to get a list of all the queues using the Coupling Facility structure that you want to delete:

  DISPLAY QUEUE(*) QSGDISP(SHARED) CFSTRUCT(structure-name)

• Delete all the queues that use the structure.

• Stop and restart each queue manager in the queue-sharing group in turn to disconnect WebSphere MQ and DB2 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.)
