Using the z/OS DUMP command

You might be asked to dump any or several of the following for IBM to resolve the problem:

• Main WebSphere MQ address space

• Channel initiator address space

• Coupling Facility application structure

• Coupling Facility administration structure for your queue-sharing group

Figure 2 through to Figure 6 show examples of the z/OS commands to do this, assuming a subsystem name of CSQ1.

The examples shown in Figure 3, Figure 4, and Figure 5 relate to z/OS only. For MVS, specify ALLPSA instead of PSA and SUMDUMP instead of SUM.
