Re: Trigger techniques

Anyone care to share what they do to facilitate being able to bring a new version of a trigger program into use.

For performance reasons we don't want to set on LR on each call - but how do you make sure that it gets refreshed when a new version is available? I can think of a number of options but each one I come up seems to have its own issues.

Very simple.

If a trigger program is active, the job(s) in which it is active have a lock on it.

Simply put, you CAN'T update it while it's active.

You could, however, set up a *DTAARA, and a check for it every time the trigger is invoked, such that LR is set on whenever the trigger sees a particular value in the *DTAARA.

Or you can just forcibly torpedo all jobs with a lock on the trigger program.

Given that we use triggers for data propagation and for workflow scripting, I know something about them.
