Replicated/Mirrored Database Configuration
Hello,
Has anybody configured JAMES to work with the mailstore database being
replicated? The replication is for a disaster recovery site, that may
at times be the "live" server, and I need to allow for some overlap.
Thank you,
Bill

Atm, We don't have a distributed message UID generation/lookup, so
running two simultaneous James instances to server IMAP will not work.
Thx, Eric

Well, I'm particularly concerned with the individual Mail Message UID.
It is entirely possible that both the Prod and the DR machines could be
running simultaneously, and we could get some overlap in UID's.
We cannot configure this with only one database backend like I've seen
your cluster configurations.

Hi Bill,
I haven't, but if you replicate on database level, it should be
transparent to James.
Maybe someone else?
Thx, Eric
