Hi,
I want to know if there is a way in WMQI to retain the trace information
over a longer period. Let me explain it in detail.

I have a broker which has say 3 execution groups. I want to start
the trace utility at the start of the day on all these components and retain
all information till end of day and do some analysis.

Also, whenever there would be errors, I should be able to read and format
the same.

Currently, I set debug level trace on all execution groups and pump in messages to the broker. I kept losing information each time I do a mqsiread log and mqsiformatlog. Only the latest information is available in the fomatted file.

So, I tried with a -c 70000 as file size to the mqsichangetrace command.
This is causing the subsequent mqsireadlog to Abort after a while.

Please let me know the way to go about this and what options do I have.

This is a testing envrionment
on AIX and I don't care about file system space and performance of the broker by enabling trace at any levels.

Your help will be appreciated.
Thanks

What are the options you specify for mqsireadlog command? Please look in the Administration manual, there is some kind of restriction on the value you specify here, it's related to how you use the mqsireadlog command.
What is the exact error message you get when mqsireadlog command is Aborted? You can try using MQSI_UTILITY_TRACE and MQSI_UTILITY_TRACESIZE variables to trace the utility itself. For more information, please refer to Problem Determination Guide.

Also take a look at the options you specify on the mqsichangetrace command. The -r parameter will reset the log and discard all of the current trace entries.

Thanks for your pointers.
I was able to get what I wanted.

I used the following commands:

mqsichangetrace RS241SI1 -u -e Phase1 -r -l debug -m fast -c 1000000

mqsireadlog RS241SI1 -u -e Phase1 -f -o $TRACE_PATH/Phase1.xml

mqsiformatlog -i $TRACE_PATH/Phase1.xml -o $TRACE_PATH/Phase1.log

Thanks again for your help.

Regards.
