RE: What's the fastest way to submit jobs from RPG?

First change I made was to make the file input primary.

Any time I've had these sorts of performance issues I've only ever found two
things that have helped.

The most bang for the buck comes from removing the K and processing records
in arrival sequence.  This is not always possible,  but too many times I
have seen people process 100% of the records, yet insist the records must be
processed in keyed sequence.

The second method may no longer be as effective as it once was.  Use IP
sequencing and use matching records.  Use the cycle as designed.  Organizing
the files in index order first might also be useful.

Please, no squeals and yelps.  The cycle and matching records is fast.  If
he's looking at an 83 day job, he needs to find 90+% improvements and those
two suggestions often yield those sorts of results.

Hi folks,

Program A reads a file and for each record submits about 20 jobs to batch to
update totals further up the hierarchy of records in the file. The batch
jobs are going to a dedicated jobq/subsystem which can have up to 25 active
jobs. At the moment no more than 3 or 4 jobs are active at a time because
Program A is not submitting them fast enough. We have tried submitting the
jobs directly from the RPG program using QCMDEXC and by calling a CLP to
submit them (contrary to (my) expectations, calling the CL was faster). At
the speeds we are seeing at the moment it would take 83 days of continuous
processing to complete the job (we are talking about millions of records).
Is there a way to speed up submission of the batch jobs from program A?

TIA

Martin
