RAC *can* provide a higher level of availability. It isn't the complete answer, but offers a level of improvement. But one needs to consider the complete infrastructure for high availability(Web servers, app servers, db servers, storage, fiber switches, SAN, QFE's, HBA's,etc,etc)

Seems like someone made a critical tactical error in the heat of the moment.. It can happen to everyone as we have found that 64% of outages are *Human Errors* and not technology related..

I don't know whether this is true or not, but this case written here shows exactly why RAC does not give you real high availability, the database itself remains single point of failure.
