Autonomous Data Guard Switchover and Failover Operations

Describes switchover and failover operations with an Autonomous Data Guard standby database.

• Perform a Switchover

  When you perform a switchover, the primary database becomes the standby database and the standby database becomes the primary database, with no data loss.

• Automatic Failover with a Standby Database

  After you add a local Autonomous Data Guard standby database, the system monitors the primary instance and automatically fails over to a local standby database in certain scenarios.

• Perform a Manual Failover

  When Autonomous Data Guard cannot automatically fail over to a local standby database, if a local standby database is available you can perform a manual failover to make the local standby database the primary database.
