Autonomous Database New Feature 2020. Autonomous Data Guard.

Standby database is now supported in Autonomous Database. When you enable Autonomous Data Guard on ADB support only 19c and above version. (Except Always-Free Tier). If your primary database goes down, Autonomous Data Guard converts the standby database to the primary database with minimal interruption. After failover completes, Autonomous Data Guard automatically creates a new standby database.

Customer is able to perform a switchover operation, where the primary database becomes the standby database, and the standby database becomes the primary database.

The system creates a standby database that stays "connected" to the primary database and automatically refreshes its data from the primary database.

Autonomous Database does not provide access to the standby database.
