Re: Activation group for an AFTER external database trigger...

As I indicated if coming from outside you must use *caller and so ibm says
*caller so *caller it is but all of this has to do with error handling.
,After has already written the record. Unless you using commitment control
you are screwed in any case.

Alan,

I find it amusing that you find it amusing about commitment control. We
interface with other platforms (middleware Java and Oracle, for example)
and have many commitment control situations where data is written on one
side and doesn't get committed, on either side, until both sides
acknowledge that the data is correct and valid.

How would you propose such to occur without it? I'm always willing to
learn a new trick.

Thanks,

Steve

That is assuming you are using Commitment Control and who on the IBM i
uses commitment control? Almost none. If I was wanting to roll back
changes, I would simply use a Before Trigger and monitor for an error to
inform the user that the update did not occur. My opinion only.

The one scenario that I have run into where *Caller was mandatory is an
update coming from an external job (A PC job). The trigger call is from the
OS and the OS is running in default activation group.

A Trigger Program should always run in the *CALLER activation group!
Why? If you are working with commitment control, the default
commitment scope is *ACTGRP, i.e. a COMMIT and/or ROLLBACK will only
work properly within the same activation group.

Hi All, I've been trying find how to define the activation group on an
external (RPG) database trigger.
Should I be using ctl-opt actgrp(*new) orctl-opt actgrp(*caller)?

If anyone knows of a link to a reference that would be great too.

Thanks,

Rob
