So, what are journals really for? Rollback and commit or something else?

Hi,

the Journal Receiver will contain this information, but its
not to easy to get it. starting journaling does not touch
your applications and would be a good idea anyway.

what about adding the timestamp (or something like this),
filling it by trigger and letting your application work with
LFs ommiting this field with identical name s to now?

Subject: File transaction date

Hi,

I'm currently adding a date field to an old PF which will hold the
date that a transaction gets modified. The file has 3 or 4
mentions in
different RPG modules that get bound by copy to almost everything.
This results in having to recompile pratically the whole
system. The
job that migrates the file takes about 2.5 hours to run and
I need to
plan it in advance so noone is using the file when ir runs.
In other
words, it's a headache.

I don't know much about journals/receivers as they aren't
used here.
But aren't they designed for this kind of information? I'm also
thinking of the rollback feature that they permit. I've never used
that either. What kind of preparations do we need to think
about to be
able to switch to this kind of file management?
