Fast-Start Failover is an Oracle Data Guard 10g Release 2 feature that automatically, quickly, and reliably fails over to a designated, synchronized standby database in the event of loss of the production database, without requiring manual intervention to execute the failover. In addition, following a fast-start failover, the original production database is automatically reconfigured as a new standby database upon reconnection to the configuration. This enables Data Guard to restore disaster protection in the configuration quickly and easily, returning the database to a protected state as soon as possible. This paper describes Fast-Start Failover and describes Maximum Availability Architecture (MAA) best practices for its use.
