Queue manager trace

The queue manager trace provides information about relevant queue manager functional and exceptional events. Use the trace under the direction of IBM® support personnel when problems are suspected in the queue manager area.

Turning on the queue manager trace

You can turn on the queue manager trace in two ways:

During IMS online initialization with the QMGR parameter in the DFSVSMxx IMS.PROCLIB member.
During online operation, with the /TRACE command.

You can specify trace output destination and tracing volume on both the QMGR parameter and the /TRACE command.

If you send output to the common trace table, you can format the table using the Offline Dump Formatter under IPCS, using either the VERBX command or the IMS Dump Formatter panels. If you send the output to an external data set, you can use the File Select and Formatting Print utility (DFSERA10) with exit routine DFSERA60 to format the trace entries.

To locate the queue manager trace in a formatted dump, look for eye catcher **QMGR. To locate the trace table in an unformatted dump, look for the trace identifier QM in the trace table header record.
