Pete, I've implemented a very similar solution recently for BEA-based application. Two database servers, Multi-master replication between two databases, 1 minute propagation interval. Works great on our hardware, which was designed for the purpose and is pretty fast. Small transactions - OLTP stuff - seem to replicate well. The same can not be said for large DML operations. So far, I've been unable to tune replication so that it is capable of propagated batch type changes for large amounts of data - the receiving site seems to be converting the DML based on internal algorithm, which throws my indexing approach out of the window. Oracle Support has been of no help, other then suggesting different indexing for failover site.

Straight forward installation, both boxes on the same subnet on their own dmz. The servers will be located on the same rack in the computer room. Very few tables storing data from an application that is tracking click through data. Does anyone see any flaws with the basic plan? Any hidden 'features' that we may run into?
