Re: estimating RGZPFM runtime

Ummm... In the limited stuff I do, I've always joined the after image to the before image on after journal sequence number = journal sequence number -1.

I kind of always assumed that the Journal logic would write both records simultaneously and thus they would have adjacent journal sequence numbers.

Seems to work in practice, but we have a P05 Power 6 that maybe isn't fast enough to cause any problem.

You lost me at your first statement.

I am thinking that you HAVE to rely on RRN when processing the journals. How else can you compare the BEFORE & AFTER images and be sure that you are comparing the same entity?
