Clearing old information from trace files

If the component that you are tracing has stopped, you can delete its trace files from the log subdirectory of the WebSphere® Message Broker home directory.

If you are tracing an execution group, you can use the -r parameter of the mqsichangetrace command to reset (clear) the trace log (the -r parameter can be specified only if you specify the -e parameter). You might do this, for example, when you start a new trace to ensure that all the records on the log are unique to the new trace.

Example: clearing the user trace log for the default execution group

To clear the user trace log for the default execution group, on distributed systems, enter the command: mqsichangetrace WBRK_BROKER -u -e default -r where:

WBRK_BROKER specifies the name of the broker
-u specifies user trace
-e specifies the execution group (in this case the default execution group)
-r clears the trace log

z/OS platform On z/OS®, enter the command F MQP1BRK,ct u=yes, e='default', r=yes
