WebSphere MQ for AIX Trace V6.0 - Middleware News

WebSphere MQ for AIX Trace V6.0 - Middleware News

Follow the instructions listed below to start, stop and format WebSphere MQ for AIX trace. Trace files are written to the directory /var/mqm/trace, so delete or relocate old trace files before beginning a new trace.

Start trace

for every WebSphere MQ process:

strmqtrc -e

Or start trace only for one queue manager:

strmqtrc -m MY.QMGR

Or start a high detail trace for one queue manager:

strmqtrc -t all -t detail -m MY.QMGR

Or start a high detail wrapping trace and limit the file size to 5MB :

strmqtrc -l 5 -t all -t detail -m MY.QMGR

End all tracing:

endmqtrc -a

Format the trace files:

dspmqtrc *.TRC

Or format wrapping trace files:

dspmqtrc *.TRC *.TRS

The trace formatter program converts binary files named AMQppppp.TRC (where ppppp is the process identifier or pid which created the file) into readable files named AMQppppp.FMT.

If you used a wrapping trace, then each time a .TRC reaches the size limit MQ renames it to a .TRS extension and starts a new .TRC file. The trace formatter can convert both files to a single formatted file, but only if you format the .TRC and .TRS files at the same time, as shown above.
