If you are controlling the trace file from outside the session, you may be stuck. But if the session is issuing its own 'set sql_trace true' call, then you try to include a mechanism for getting it to do:

alter session set tracefile_identifier = 'something_new' on a regular basis. This causes the current trace file to close and a new trace file to open, with 'something_new' included in the file name.

I had given up on trace files a while ago...

I could NEVER format the trace files that went to SYSOUT=20 Finally in 8.1.7.4 we were about to write trace files to DASD I have not had any luck using tkprof to format these files though.

Also, after creating the tracefile, the trace file is not always = readable.
For some reason, the oracle service / database keeps am exclusive lock = on
the file and I cannot view it. Obvioulsy I cannot shutdown the database=20 just to release the lock.

Maybe I will try trace files again...=20 Will have to record time and date of trace, what I was doing and check = hours (days?) later to see if file lock has been released :-(
