Activation Groups

[Ralph Porter]

Hi,

I came across a situation on our system which is causing me some
confusion and initially a little panic! here it is:

We have an override to a file (OVRDBF) in an OPM CLP scoped to
*ACTGRPDFN
the CLP runs in the default activation group.

A call is placed to an ILE RPG program that runs in ACTGRP(*NEW)

The ILE RPG program uses the overidden file hence the override is in
place, whilst relieved, I really don't understand why, can anyone
explain.

Has there ever been anything so complicated to understand!

Thanks,

Ralph.

You should scope to *JOB and wont run in to problems.

Have a look at the job while it is running, especially to the activation
groups,
you'll be surprised to see two default groups!

The scope of the override with ovrscope(*actgrpdfn), when created by a
program runnin gin the default activation group is *calllvl. All OPM
programs run in the defualt activation group, so your orverride is scoped to
call-level of the OPM CL program. That is why the override is visible to
the ILE RPG program.

Why is it complicated? Backwards-compatibility. OPM exists so programs
migrated from pre-ILE will run the same, more or less, as the did in the
pre-ILE world. The best path to simplification is to convert all OPM to
ILE. Mixing OPM and ILE in your application is the most complex approach.

I sure wish they would have done the same thing for the open scope of
OPNQRYF. That's bit me in the butt more than once.

I didn't say that anything surprised me.
