You can use Oracle Cloud Infrastructure events to respond when Autonomous Database changes its state due to a Backup-Based Disaster Recovery related event.

Autonomous Database events include the following:

• Begin manual failover
• End manual failover with failover result of success or failure.
• Begin switchover
• End switchover with switchover result of success or failure.

Based on events you can perform actions or send notifications. See Events and Notifications for a Standby Database for more information on using events and producing notifications.
