Controlling WebSphere MQ trace

To control the WebSphere MQ trace data collection at start up, specify values for the parameters in the CSQ6SYSP macro when you customize WebSphere MQ, see Using CSQ6SYSP for details.

We can control WebSphere MQ tracing when the queue manager is running with these commands:

We can chose the destination to which trace data is sent. Possible destinations are:

SMF

System Management Facility

GTF

Generalized Trace Facility (accounting trace only)

SRV

Serviceability routine for diagnostic use by IBM service personnel

For daily monitoring, information is sent to SMF (the default destination). SMF data sets usually contain information from other systems; this information is not available for reporting until the SMF data set is dumped.

We can also send accounting trace information to the GTF. This information has an event identifier of 5EE. The WebSphere MQ for z/OS Problem Determination Guide describes how to deal with WebSphere MQ trace information sent to the GTF.

For information about WebSphere MQ commands, see the WebSphere MQ Script (MQSC) Command Reference manual.
