Hi Roger


I like that idea - I haven't checked enough code here to know, but I think we depend on existence only.


Regards
Vern

When I did a semaphore data area, I'd always populate it with the current job info - name, #, user, and any other pertinent info - maybe some parm/key value if applicable.

Just in case I needed to troubleshoot some conflict.

Perzackly, Jim - that's why I suggested QUSLJOB with a specific job name in the parameter - have know James too long, right?

Putting an *EXCL on a *PGM was suggested - I've never seen that work - just tried it with a simple program that sent an *INQ message in it, then locked it and called it. While waiting for a reply, I went to another job under my name in the same system, called the program, and i got the same *INQ message.


So locking the program didn't stop me from using it in a different job - would it block a different user? I can't test that here at the moment.



We often lock something like a *DTAARA to act as that semaphore, sometimes *EXCL, sometimes *EXCLRD, it appears in a quick iSphere search.


Cheers
Vern

All good stuff, however remember that James is sometimes running systems
that are not real current, so the SQL helpers that IBM has built may not be
available. Hence the semaphore.

Hi,

You could also execute the following SQL within CL

SELECT count(*) into :jobcount
FROM TABLE(QSYS2.ACTIVE_JOB_INFO()) B
WHERE JOB_NAME like '%Jobname%'

If you get jobcount = 0 then you are good ..

This won't work if the jobs that are no longer active still have spool
files.

Hi ,

I just do a WRKJOB jobname and then monmsg CPF1070

If the MONMSG catches CPF1070 (job not found) then I continue to submit the
new job...
