The channel initiator trace

See Figure 4 for information about how to get a dump of the channel initiator address space. Note that dumps produced by the channel initiator do not include trace data space. Trace data space, which is called CSQXTRDS contains trace information. We can request this by specifying it on a slip trap or when you use the dump command.

To run the trace using the START TRACE command, see the WebSphere MQ Script (MQSC) Command Reference manual. We can set this trace to start automatically using the TRAXSTR queue manager attribute. For more information about how to do this, see the WebSphere MQ Script (MQSC) Command Reference.

We can display this trace information by entering the IPCS command:

LIST 1000. DSPNAME(CSQXTRDS)

We can format it using the command:

CTRACE COMP(CSQXssnm)

where ssnm is the subsystem name.
