Re: Identity Columns

Hi Dave,

As I said above.... Both *programs* run in QILE and end with *INLR.

The Service Program runs in *CALLER and *closes all files and cursors* of
which there are very few.

I don't think I've every seen a program opened in a named activation group
that stayed open after a RCLACTRGP.
That said, I always have a cleanup() routine in my service programs that
gets called when the program is done with it.
Cleanup() closes all open files, all open cursors and in some cases resets
global data which might have been designed to persist for a time.

RCLACTGRP was something we coded into the menu system at my last client
site to ensure everything was cleaned up because back at the menu system it
was possible to brand-switch which meant different library lists.
My current site doesn't consistently use a menu system though so I have to
take other measures to control things.

best regards,
Craig

My code also seemed to be working fine with RLA and generated always
columns until I did a couple of quick tests to make sure the named
activation group was being cleaned up, which involved switching library
lists and then I seemed to get the intermittent problem.

I noticed when switching environments and inserting records that it

seemed

to skip one identity value ( e.g the highest INT ID I had was 12 and it
would generated 14 instead of 13 as the next number )
I know this makes it sound like I've leaving something open but I'm sure

I

am not. Although there are 2 programs and a service program involved,

only

the service program does database I/O. Both programs run in QILE and end
with *INLR. The Service Program runs in *CALLER and closes all files and
cursors ( of which there are very few ) and the Activation Group is

being

reclaimed so I can't see what resource might be left around.

*INLR does nothing in a service program. So, unless there is an
explicit CLOSE of the file in your service program then the file is being
left open by the service program. Even reclaiming the activation group
does not close the file as far as the service program is concerned -- at
least, that is a problem I have encountered on a number of occasions. I
even reported an error I was seeing to IBM and they came back and said
"functioning as designed." They said the reclaim activation group was
"destroying" the control blocks associated with an open file but that the
RPG service program still thought the file was open and treated it as
such.


Sincerely,

Dave Clark
