I have been given the task of designing a way to prevent batch jobs from
filling up our spool packs. The main culprits are traces with large input
files that result in 10's of millions of lines of trace data on the spool
volumes. The DD names for these is usually SYSOUT so it appears the best
solution is to use SMF exit IEFUSO.  I see in IESUSO the Common Exit
Parameter Area which has some fields I need:   LPAR in the SID field, a
JOBNAME field and most importantly the JOBCLASS field. The JOBCLASS is
important because the limits are to be enforced on test jobs on and that
will be determined by the JOBCLASS the job is running in. This is what my
questions are:

1.) I also need the logon id the job is running under. We will allow even
test jobs with certain logon ids to continue on. Can I get to that in
IEFUSO somehow?

2.) Can I put a WTO to the SYSLOG from this exit? This exit is not going to
cancel the job. It will put a message to SYSLOG and the automation's
software will do that if further examination determines that should be
done.

3.) The exit has a field that is used to pass back a SYSOUT limit
extension. I don't really want to do that. What happens if I don't do
anything with that field.

I also considered JES2 EXIT 9.  The manual says EXIT 9 is not used for jobs
that exceed OUTLIM values and to use IEFUSO.

Thank You,
