Re: Triggers & AGs

[David Morris <dmorris@xxxxxxxxxxxxx>]

Jon, and others,

After receiving conflicting replies I decided to try some tests.  It appears 
that system programs are ignored when the activation group for *CALLER programs 
is set.  This is very good news in our environment.  We have been specifying 
*CALLER for all programs and service programs.  I spent a few hours looking but 
have yet to find a line in a manual that says something like "programs created 
with ACTGRP(*CALLER) and invoked by system state programs will derive their 
activation group from the prior user state program on the stack".

I guess the key word in the following text taken from the ILE concepts manual 
is "Originates".  

"ILE programs and ILE service programs can be activated in the OPM default 
activation groups if two conditions are satisfied:

The ILE programs or ILE service programs were created with the activation group 
*CALLER option.

The call to the ILE programs or ILE service programs originates in the OPM 
default activation groups."


Thanks for your patience,

David Morris

You are correct - you should also be aware that by using *CALLER you have
opened up the possibility that the trigger program can have multiple
invocations active at any one time (i.e. one in each AG - including the default
- that it gets called in).  This may not be what you want.
