Here we go. This process assumes the object in CPF1002 is in the job's
library list and that you know its type (*FILE, etc.). The basic steps
in a program that finds who has an object locked are listed below.
1. Create a user space. This will hold the list of jobs locking the
object. API QUSCRTUS.
2. Obtain a pointer to the user space. API QUSPTRUS.
3. List the jobs locking the object. API QWCRLCKI.
4. Retrieve the header information needed to step through the list.
5. Perform the steps you feel are necessary.
- If your job has the lock you can release it. This may be what you
6. Clean up your work object(s).
7. End the program.

Bear with me, I just started new job Monday, so I'm.. adjusting. :-)
I need to monitor a process that is kicked off by a homegrown CL
The process calls 3rd party apis to generate ASNs. (advanc ship notice)
The 3rd party apis can generate msg CPF4128, if 'something' it needs is
not available to it. (ie, user is using a file, for example)
I was thinking to monmsg for cpf4128 in the homegrown CL program.
Error message CPF4128 appeared during OPEN for file EDDALT (C S D F).
I'm not quite sure the best way to go about this but, I'm looking for
The best way to do this for this homegrown CL program, and probably
After that, be introducing the same technique into other similar
Does that help clarify?
Can we step back a from the problem a second? What exactly is it you
are trying to accomplish? Modify a program for production to
automatically monitor for a message and take some action?
