Disaster Recovery (DR)Preparation

We do Oracle10g CRS (no _HACMP_) on 2xNodes AIX5.3 connected to FC SAN
DS4800 to serve our members which is a real time application.we
planning to do a Disster Recovery plan for this service,DR plan need to
recover 1 hour max time, the site will be about 35Km away,system must
be restored to the last transaction, on the backup site we are thinking
to palce the same identical hardware of our Production, AIX Servers and
SAN DS4800Our data will be mirrored across a WAN link E1.

Is there anyone that have some experience of Veritas, TSM or STORIX for
DR.

what about HACMP/XD GLVM over a WAN lines (T1,E1 or E3)....
for failover and keeping data on both sites sync'd.

What about using a standby instance in "Instant Protection" or
"Guaranteed Protection" mode at the standby site? Redo info would then
be automatically shipped over to the DR Site and no need for HA/XD or
remote mirror on the DS4800, unless you are required to mirror other
filesystem stuff.

If you need 1 hour recovery time, its suggested you use RDF or Metro
Mirror (SAN replication). TSM restore would just take too long,
depending on your tape+library+drive+amount of data.

You should also consider using GLVM (Part of AIX 5.3 now).
