I am trying to get a handle on this.  Where can I find out information
about remote journaling?  I have looked at the Backup & Recovery Guide
V4R4.  Has anyone here implemented remote journaling as part of a DR
plan?

>From a DR standpoint, can I rely on just applying journal entries from a
remote journal to get my local database back in sync?  Or is this just
going to be too slow and necessitate database replication on the remote
system?  Or is it, "It depends"?

I've seen information for the *NoMax product which, to the best of my
knowledge, uses OS/400's remote journaling to feed its applications to
replicate databases on the remote system(s).  Is there much advantage to
going with a third-party product like this when it *appears* to be a
somewhat simple task to do the replication via roll-your-own?

Am I correct in the understanding that if you set up remote journaling
with synchronous journal entry replication, that the source system's
application must wait until the target system has added the journal
entry to the remote journal?  If so, is this even usable from a
performance standpoint?  I would imagine that batch update jobs would
have horrendous performance.  What would happen if you lose
communications for several minutes?
