RE: File Trigger Performance -- MIDRANGE-L

I would also avoid *CALLER. Because multiple job can initiate the trigger so may have several activation group. Probably not a big deal though.

If you are willing to change the code of the trigger program, here is a suggestion:
- Add a table to the program that hold the jod id (number, name ...) and it's type (batch/interactive)
- When the trigger is called, check to see if the job is already in the table
- if so, retrieve the type of job from the table
- if not, call the API to retrieve the type of the job and add this information to the table

This way you will call the API just once per job instead of once per read. My guess is that is where you will get the best performance boost.

Denis,

Thanks .... would the activation group setting of *CALLER work as well?
When I display the *PGM now it reads QILE for the activation group.

I have a customer using one of our products that employs a physical file
trigger program for READ. The trigger program is an ILE program that
starts up in a CLLE. The first steps in the CLLE are to retrieve the run
status (batch or interactive) and then check a setting in a data area. If
the job is running in batch and the setting from the data area tells the
program to ignore batch reads, then a RETURN is immediately issued.

Seems easy enough, but the customer is reported very poor performance now
on batch applications.

Any ideas?
