Re: AW: Program runs once correctly, not again until signoff/signon

Thanks all.

It was activation group. I do not know if the PDM option supplied by
the vendor to compile was changed. , but, Default activation group
was NO and Activation group was *CALLER.

I left the CLLE compile options as is. For the called RPGLE, I added
actgrp(*NEW) to the H-spec.

Works now.

Twenty years ago, I worked on a Pr1me computer. They wee in the
process of rewriting their operating system from a rather unusual
assembly code to C. I stumbled onto a weird bug in a system command.
Run SPOOL -LIST to see what is printing and waiting. Run again and
get output from different command. Only fix was log off and on. They
did not have the same fix process that IBM had even back then.

Just shows how well even v5r4 was tested, based on few cumes being applied.

Actually, RCLRSC will remove both OPM and ILE programs if they are in
the default activation group.

The problem is service programs. Since RCLRSC does not understand
service programs, it'll see the open files and close them, but it'll
leave the service programs in memory, and the service programs won't
understand that their files have been closed. So next time they access
a file they'll end up accessing memory they aren't supposed to be using.
Usually, this causes them to crash with an ugly error.

ILE activation groups work MUCH better for ILE programs than the default
activation group. I don't understand why, after 18 years of ILE, there
are still people who do foolish things like run ILE programs in the
default activation group. Stubbornness never to learn anything new?!
What else could it be?

I assume the CL program is running in the default activation group and the
RPG (service) program is compiled with activation group *CALLER (so it also
runs in the default activation group).
The default activation group cannot be ended within a job, but only by
ending a job.
When executing the RCLSRC (reclaim resources) OPM programs are removed while
ILE programs are not. This may cause a lot of problems.
... avoid using RCLRSC at least if there are ILE (service) programs running
within the default activation group
