Actually, even something like Hp's ServiceGuard is not so graceful, depending on the app using the database. I have had a database fail and know one know and a different database fail and everyone know. You really have to take into account with the app that it might lose connection. You need to code in retries and all that stuff. If you get it coded in such a way that it can handle a 5 minute interruption then all is good.

When you CAN do the graceful failover, it's a lovely thing :) Rachel __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!
