Replication happens in discrete chunks and there is a distinct possibility
of losing data if replication was used in banks. Banks and other financial
institutions are using OPS with EMC or DiskShark (IBM) based remote
replication
facilities. I know that Oxford Health Plans uses 4-way parallel server for
both data safety and performance reasons.

Thanks. If anyone else knows of anything out there for really high volume
replication over
a WAN it would be appreciated. I was under the impression that banks, credit
card companies, and
telephone companies were replicating there data using Oracle but it doesn't
look like it.
Anyone know what they are using? It also seems like for certain apps they
would have to
use synchronous replicatiion. Has anyone had any experience with Clustra?

it looks like it will be kewl to flip between primary and standby WITHOUT
rebuilding :)
