Formatting and identifying the control block information
After capturing a trace, the output must be formatted and the IBM® MQ control blocks identified.
Formatting the information
To format the user parameter data collected by the global trace, use either the batch job shown in Figure 1 or the IPCS
GTFTRACE USR( xxx )
command, where xxx is:- 5E9
- To format information about control blocks on entry to IBM MQ MQI calls
- 5EA
- To format information about control blocks on exit from IBM MQ MQI calls
- 5EE
- To format information about IBM MQ internals
You can also specify the
JOBNAME( jobname )
parameter to limit the formatted output to specific jobs.
Identifying the control blocks associated with IBM MQ
The format identifier for the IBM 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 IBM MQ
- CSQW072I ENTRY: MQ user parameter trace
- CSQW073I EXIT: MQ user parameter trace
