identifying WebSphere MQ control blocks, format identifier" /> Formatting the information

 

Formatting the information

To format the user parameter data collected by the global trace, use either the batch job shown in Figure 13 or the IPCS

GTFTRACE USR(xxx) command, where xxx is:

5E9

To format information about control blocks on entry to WebSphere MQ MQI calls

5EA

To format information about control blocks on exit from WebSphere MQ MQI calls

5EE

To format information about WebSphere MQ internals

We can also specify the

JOBNAME(jobname) parameter to limit the formatted output to specific jobs.

Identifying the control blocks associated with WebSphere MQ

The format identifier for the WebSphere MQ trace is D9. This value appears at the beginning of each formatted control block in the formatted GTF output, in the form: 

USRD9

 

Identifying the event identifier associated with the control block

The trace formatter inserts one of the following messages at the top of each control block. These indicate whether the data was captured on entry to or exit from WebSphere MQ
