Use the z/OS DUMP command

To resolve a problem, IBM can ask you to create a dump file of the queue manager address space, channel initiator address space, or coupling facilities structures. Use this topic to understand the commands to create these dump files.

We might be asked to create dump file for any or several of the following items for IBM to resolve the problem:

Main IBM MQ address space
Channel initiator address space
Coupling facility application structure
Coupling facility administration structure for the queue sharing group

Figure 1 through to Figure 5 show examples of the z/OS commands to do this, assuming a subsystem name of CSQ1.
