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.

Subject: RE: Capacity Planner from OEM VS Statspack
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 :-(
