Experience with Oracle RAC

I’d be interested to hear your experience working with RAC with webMethods. Our DBAs are implementing RAC and I have questions on how webMethods (DataDirect Drivers) will respond to some of the RAC functions.

Also interested in any specific items you had to perform to make your implementation better.

Node to Node failover. - Any special configuration?
Cold backups - Reconnecting without errors or recovery after error?
