RE: Passing data structure to batch job

Mark,
This new process is an extension to existing work.
The part that's in production currently runs in a single-thread job queue that is for jobs that don't take too long. The job provisions a service order to the telecom switch equipment. Now I need to further provision that same order to some other equipment that requires access via web services, and they take some time. It seems that since the first job has already collected some details about the service order that will be needed by the new job, I should utilize that and pass it to the long-running process, rather than have to go rediscover it all.

Hi, Michael:

Since the first job is already running in batch, why needlessly
complicate matters by spawning several additional batch jobs? That
introduces all sorts of additional problems. How will the first job know when the other jobs have completed? How will they get back any results? etc.

Just call these other program(s) directly from the first program. That way, you can easily pass whatever data structures are needed, etc., with no worries due to the vagaries of the command parsers and quoting and all that stuff that happens when you need to cross a job boundary (e.g.
via SBMJOB).

Hope that helps,

Mark S. Waterbury

Never tried this before: I have a sqlrpgle program running in batch that needs to submit another program to batch and pass a data structure to that new job. The original job executes in just a few seconds, the new job executes calls to web services that take maybe 45 seconds each to return results, so I'm reluctant to burden the original job with that kind of wait. I normally use a call to QCMDEXC to launch (via sbmjob) such a job from RPG, but my question is more about passing a data structure ( like I'd do in a prototyped call ). Is a data queue required here? ...I have no experience with those.
(Extra points to a response that say's "it's easy") Thanks.
