PASE doesn't use prestart jobs by default, but you can tell it to.


http://www-01.ibm.com/support/knowledgecenter/api/content/nl/en-us/ssw_ibm_i_71/apis/qp2runpase.htm

I don't know if that is the exact link, but this has similar information.
If you go down to "usage notes" you will see:

---
QIBM_PASE_USE_PRESTART_JOBS

When this ILE environment variable is set to Y, IBM PASE for i runtime
uses prestarted jobs for child processes created by fork and for any job
started by the systemCL IBM PASE for i runtime function (to run a CL
command). You should add prestarted job entries (ADDPJE command) for
programs QP0ZSPWT (used by fork) and QP0ZSPWP (used by systemCL) to any
subsystem description that will run jobs that use this support.

That is the configuration I am attempting to use. I've created the
prestart job entries and I set that environment variable. It works, but it
only uses the jobs once, which really isn't the behavior we were after. We
were hoping it would use the 2 prestart jobs over and over.

I'm not aware of PASE using prestart jobs....

Where are you getting that impression from?

I am a bit confused on something.

I created pre-start job entries to handle PASE calls made in a

particular

subsystem. I was under the impression they would be reused, but it

appears

they end after 1 use. MAXUSE was left at the default of 200.

Am I missing something? I am not sure if this is a misunderstanding of

how

prestart jobs work or if I am seeing behavior that is not expected.

Scott

Klement had mentioned unpredictable behavior if I didn't "fork" and

setup

output descriptors. I am not sure if this falls in that category or

not.

The scripts I am running function just fine. All the jobs seem to be
completing normally when I look at the job logs.

Thanks for any help.
