Andy,

I think I found what was the problem: we were convinced that _every_ update
was supposed to be journaled, but apparently only updates that have a
different UB and UP image are written to the journal, and not those records
where the contents of the fields was not changed, or overwritten with the
same value it already contained.

So I guess it's not a hole in the reliability of journaling.

This said, however, I do believe that it would be better if there were an
option to include _all_ updates in the journal, similar to the TRGUPDCND
(*ALWAYS) keyword for ADDPFTRG.

Anyway, thanks to all those who responded.

Subject:  RE: CHGJRN


Peter,

What you are describing is very important.  While it may be necessary to
find a work-around, I would encourage you to open a problem with IBM.
Journaling is the basis for system recovery in a number of scenarios and
you have described a gaping hole in its reliability.  If a transaction
cannot be recovered or recreated using a journal, what good is the
database?  Unless journaling is ended, _all_ changes _must_ be
journaled.  If IBM thought they were doing a good thing by having the
CHGJRN command process asynchronously, perhaps they need to rethink.

Regards,
Andy Nolen-Parkhouse
