Sounds like a CL wrapper that self-submits and runs the program under a
specific job name is your best bet.

You can also have the CL check for & lock a specific object, either a data
area or the *PGM object itself to ensure that only one copy is active.

I need to be able to give operations a method of ending and starting a
particular program
If the program was already running - then I don't want multiple
occurrences in the mix - so therefore - don't submit a new job
If the program is NOT running - then I don't call ENDJOB etc.

Like I said - we don't have the source to the program(s) - so I cannot put
any changes within it

I also thought of a CL wrapper - for submitting the call of the program,
but I was hoping there was something to definitively tell me that a program
was running

There's no lock on a *PGM object when you run it...

AFAIK, there's no easy way to know if a program is currently being used.

QAUDJRN could track when it was started....

I suppose you could dump the call stack of every active job and look for
the program.

But for ILE, the program could still be active in a named group withing
appearing in a job's call stack.

What are you trying to accomplish?

Hi everyone
Before I forget, we are on V7r1

Does anyone know of a way/method/process/api etc, to determine if a
program is being run

I thought of using this SQL statement (below) into a file and then
interrogate that file I got this from this web site
http://ibm.biz/DB2foriServices under Work Management Services, but I
need to know the job name involved, and who to say the program is
running under a particular job name - or if that job name is in fact
running that program


SELECT JOB_NAME, SUBSTR(JOB_NAME,1,6) AS JOB_NUMBER,
SUBSTR(JOB_NAME,8,POSSTR(SUBSTR(JOB_NAME,8), '/')-1) AS JOB_USER,
SUBSTR(SUBSTR(JOB_NAME,8),POSSTR(SUBSTR(JOB_NAME,8),'/')+1) AS
JOB_NAME2 FROM TABLE (QSYS2.ACTIVE_JOB_INFO('NO','','','')) AS X


I then thought - well if the program is running, there has to be a
lock on that program So I thought of using WRKOBJLCK, an api, the
following SQL, also from the same web page, but who is to say the lock
is due to the program running

SELECT * FROM QSYS2.OBJECT_LOCK_INFO


I need this information so that I can see if the program needs to be
ended I don't have access to the source - so I cannot change it to set
a data area

Any and all help would be MUCH appreciated
