Re: Controlling the execution sequence of dependant jobs in JES2

For the longest time before we moved the application to a scheduler we had a

got around this by simply setting the priority of all input jobs to be the same
priority ($TJ1-9999,P=10) which meant that all the jobs ran in the order we
needed. It could be further qualified to specify a job mask $tJ1-
9999,JM=MYJOBS* if needed.
It wasn't ideal but it worked for us for several years.

Is it possible that this worked for you because you also had
CNVTNUM=1?

And some questions:

If CNVTNUM>1, do the multiple converters operate asynchrously, so
that even "hundreds of jcls within the one deck" could run out of
order?

If the jobs are submitted with TYPRUN=HOLD and released later, will
they run

o In order of release?

o In order of conversion?

o Other (specify)?

Might a program use the SDSF API to detect when each job was converted,
and submit each only after conversion of its predecessor completed?

I know, I'm close to suggesting a RYO scheduler. But ISVs are
compelled to resort to such things when they can't count on
all customers' having a needed utility.

Is there, perhaps, a simple scheduler available from CBTTAPE? A
Google search suggests:

//*+File 332: Automatic Job Scheduler in MVS JES2 environment * DOC FILE

And, ironically:

//*+File 388: David Cole's Job Scheduler package * DOC FILE

(Is there a better way to find abstracts of CBTTAPE programs than
by dowloading and browsing each?)
