Hi. I am a fresher in AS/400 and need a complete or as much as possible information on AS/400 batch processing. How it is done or how it works? How to initiate?

Thanks. We'll let you know when a new response is added.

Simply said, batch jobs are generally initiated with the SBMJOB command and they execute (like all jobs) within a subsystem.

Batch job differ from interactive jobs in that they require no user interaction and can be left to run on their own, whereas interactive jobs are tied to a workstation.

I would take a look at the IBM work management manual.

On a system with the configuration as delivered by IBM, one significant difference between batch and interactive jobs is that batch jobs run with a longer time slice than interactive jobs. This is adventageous to programs such as reports and nightly updates that require no operator interaction. This type of program runs more efficiently when submitted to batch. Another difference is that batch jobs typically execute at a lower priority. Again, this can be changed but its generally a good idea not fiddle with this too much. When jobs run in batch it gives your interactive users quicker response to screen changes, menu changes, program calls, etc. Unless you have an Enterprise class machine with all computing power available to QINTER, there is more computing power in batch. For example, less than 6% of the computing power of our machine is dedicated to QINTER.
