I saw a good example of this at an OpenWorld session this year. The
presentors had built a "logical" database spread across three physically
separate sites. Each site used RAC for its database and application
servers, and the databases were kept in sync using advanced (multi-master)
replication. Web traffic to the app servers was managed using hardware load
balancers. Between the three sites, they've had 100% uptime for 5 years.
You can download the PDF of their presentation from Oracle's Openworld site.
It is titled "Database Consolidation for Enterprise Cost Reduction."
