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.
