Resolution:
Real Application Clusters (RAC) environments are functionally equivalent to single-instance Oracle database configurations. In other words, you do not need to make code changes to deploy applications on Real Application Clusters if your applications ran efficiently on single-instance Oracle configurations. So a scalable application on a single node Oracle server will be just as scalable on a multi-node ORAC.  

Connecting clients to Oracle cluster database is the same as connecting to a single Oracle database.  No changes are needed to move clients from single database to Oracle cluster database based Oracle databases.  This makes migrating to Oracle cluster database easier.

As far as we know there are no known issues with the use of Oracle RAC with BWC and/or IC.
Please NOTE that no testing with RAC has ever been done by our QA team.

From quick reading of materials on the Oracle site, we do not see anything that indicates that RAC FAN will cause the application to fail if the notification messages of available resources are not used.  We believe that since we connect to the database instance, the use of RAC should be transparent to BWC/IC.

Is Oracle10g RAC supported with BWC 5.3.0?
