Yes, Chandra, that's exactly what I was looking for. I just didn't have
the right title. Excellent!

May be he was referring to Oracle RAC Extended Cluster. Please see -
http://www.oracle.com/technology/products/database/clustering/pdf/Extend
edRAC10gR2.pdf to start with and for more information on Extended
Clusters.

Subject: RAC Geographical Architecture
I recently attended the Oracle RAC class, and in the class, it was
claimed that 10gR2 removes any geographical limitations on the
implementation of RAC nodes. In other words, as long as your network is
robust enough, your servers could be located many miles apart (whereas,
in Oracle 9i, there was a 500 foot limit using fibre-optic connections).
I can't seem to find any documentation of this. The Oracle consultant
that helped teach the class claimed this was already being done at
various customer shops, but he didn't recommend it because of network
reliability issues, but that the future may make it more viable.
Can anyone on the list make the claim they are doing this?
Are they also mirroring datafiles geographically?
What technology supports this?
Does anyone have any comments on whether this is a valid architecture?
