Trigger question

[K.Forsythe]

I am not sure, as I have avoided read Triggers. I was told by a trusted source that creating even one read trigger on the system requires a change in the way the OS handles I/O and dramatically reduces system performance. Perhaps that has been corrected since then? My expectation is that the changes are not passed back to the program which originally caused the trigger to execute. Anyone know for certain?

Trigger question

It seems to me, anyway, that IBM's documentation on triggers is rather light. I couldn't find an answer to this question. If I have an *AFTER *READ trigger, with ALWREPCHG(*YES), and I make a change to the data in the record buffer in the trigger program, are those changes in the record passed on to the program reading and calling the trigger?

Trigger question

I tried this last week. changes are not passed back to the program which originally caused the trigger to execute. ALWREPCHG has no impact on *read event
