Hi All,
We had an issue in which the files in /var/mqsi/common/log kept on increasing and filesystems got full. We found that trace was enabled for a flow. So we disabled the trace . Now I would like to know if it is ok to delete the files under /var/mqsi/common/log ? Will it corrupt broker files in any way?

please help

If there are large files related to a trace on a flow you can shrink them by:-

1) enable usertrace for the flow using the -r option on the changetrace command.
2) a second or so later, disable the usertrace.

That should shrink the files.

Personally, I wouldn't delete any files in that directory.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.

You can also adjust/help prevent the same problem re-occuring by using the -c flag on mqsichangetrace to limit the number of trace entries it pulls.

Thanks for the inputs. What about the files that already got created? Can we delete them? Is it ok to do that?

Probably not.

The statement from smdavies99 to use the -r option will *reduce the size* of the files.

I have ruthlessly deleted the log files out of /var/mqsi/common/log before when people have left on user trace and created humongous log files.

I haven't observed any adverse affects but YMMV.

You could always cat /dev/null > [huge log] to empty the file without actually deleting it.
