Hi All,

I have one simple doubt having multiple job cards in single JCL.

1) Could anyone tell in which situations we require more job cards in a single jcl icon_question.gif

2) How many JOBCARDS at the maximum we can submit in single JCL?

Thanks & Regards,
Suresh.

I had to run several merva-queue-download jobs after some processing.
before I implemented the serveral jobcard solution, queues were downloaded one after another... some queues may take up to 2 hours to be printed so if all download jobs had to wait for this download job to finnish... of course you could roughly determine (by size of queue and what queue) which would take longer but it needed follow up...
after testing we realized we could download two queues from same merva-cics environment without problem
so I defined one JCL proc per queue and submit a 'global' jcl deck with minimum changes needed (two ispf change commands)...
that way we have up to 12 download jobs running... shorter ones do not wait on long running ones...
in short it runs more efficiently

that is one example...

q2 I think it is something like 255...

Hi Suresh,

I'd say that there is no numeric limit to the # of jobs you can submit. One limiting factor, of course, is the size of the Job Queue defined. There are probably other factors from which the job limit could be calculated.

Think of it. Jobs are submitted continually throughout the day by I/o cntl and other quarters. I've never heard of those processes stopped because a number limit has been reached.

Regards, Jack.
