RE: Calling Program information

We journal everthing to be sent to a DR box.
Even with everything journalled the performance is very good with today's processors.
For 1 file. You won't even notice it.
You can restrict the size of that the journal will reach before the system detaches it and starts another and have some job remove detached journals.

I doubt the journal would get that large...

Think about it, assuming your Order file's record size + the journal entry data totals 500 bytes.

At one update a second, a day's worth of journal entries takes only
(500*60*60*24) = 43,200,000 bytes or 43.2 Megs.

If you got 1GB of spare disk space, you've got room for more than 20 days of journals.

Actually, IBM has a calculator you use to determine space requirements:

Performance might be more of an issue, since journaling without the use of commitment control has a negative impact on performance. But since you're only talking about a single file, I'd be willing to bet you won't notice it.

Heck if it were me, I'd look at journalling all my important files.

I've worked for small shops, medium shops, and large shops; journalling was used by all of them.

HTH,
Charles

I thought about journaling but the file is our Order file and it's constantly being updated.  The journal will get quite large quickly.  I only want data in the file when I know I have found a problem.  And, I may still go with journaling.  Especially since it looks like the information I'm looking for isn't available without it.

Thanks for your input.

Why not just journal the file? It gives you program name, user, time,
all sorts of useful info for this type of problem.

Does anyone know if any of the "Information" data structures has the
name of the program, if any, that called the program you're in?



I'm going to put a trigger on one of the files in our system to save a
record in a separate file anytime a record is deleted or a specific
field within a record is blanked out.  I'm tracking down the cause of
two separate issues here and it would be nice to be able to add a
field to the saved record that says what program called, or caused,
this trigger to run.



Thanks,
