Anyone use that with something to automate the parsing out the
before/after images?

Just a word of advice...

If you don't currently use journalling, and you want to start journally
for
just this one file...

Then sure, it would make for a quick and easy solution.

However, some things to think about
- How do you intend to display the journal entries? DSPJRN in an of
itself
is not very pretty. The table's data is just one big blob. It gets even
more complex when you have nullable fields and/or MINENTDTA() of other
than
*NONE.
- If you ever need journalling for something else such as commitment
control or HA, then you're going to have problems keeping receivers around
forever.

IMHO, planning on keeping journal receivers around forever is not a good
idea.

Consider instead a program that harvests the journal entries and stores
them someplace.
You may be able to start with the CMPJRNIMG command as laid out here:

Personally, if I really _HAVE_ to (for legal reasons) have a record of
changes forever; then I'd be looking at a third party compliance tool.

I'm sure there's more...

I need to keep a permanent log of all data changes in a particular PF. I
can think of two ways to accomplish this.

1. A DB2 journal with the receivers set to never expire.

2. A trigger that would write the before images to a separate PF.

I expect questions of "who changed what when" to be a weekly occurrence.

Either of those options sound better than the other? Anyone have a door
#3?
