Use the mqsireadlog command to access the trace information that is recorded by the user trace facilities.
mqsireadlog IB9NODE -u -e default -o trace.xml
where:-u specifies user trace
-e specifies the integration server (in this case, the default integration server)
-o specifies the output file (in this case, trace.xml)
This sends a log request to the broker to retrieve the user trace log, and stores the responses in the trace.xml file. The trace.xml file is created in the directory in which the command was run. You can view this file using a plain text editor.
