Re: Log all PF changes?

[Charles Wilt <charles.wilt@xxxxxxxxx>]

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...
