Enable Autonomous Data Guard
By default and at no additional cost, Autonomous Database provides a local backup copy peer for each Autonomous Database instance. You enable Autonomous Data Guard by changing the disaster recovery type to use a standby database. Autonomous Data Guard provides a lower Recovery Time Objective (RTO), compared to using a backup copy peer, and provides for automatic failover to a local standby when the primary database is not available.
When you change your disaster recovery type to use a local standby database, you also have the option to add a second cross-region disaster recovery option, either a cross-region Autonomous Data Guard standby database or a cross-region backup copy peer.
Perform the following prerequisite steps as necessary:
-
Open the Oracle Cloud Infrastructure Console by clicking the next to Oracle Cloud.
-
From the Oracle Cloud Infrastructure left navigation menu click Oracle Database and then, depending on your workload, click one of: Autonomous Data Warehouse or Autonomous Transaction Processing.
-
On the Autonomous Databases page select your Autonomous Database from the links under the Display name column.
To change your disaster recovery type to add a local Autonomous Data Guard standby database:
Notes for changing the disaster recovery type to a local Autonomous Data Guard standby database:
-
Autonomous Database generates an Enable Autonomous Data Guard work request. To view the request, under Resources click Work Requests.
The work request may complete to 100% before you see Autonomous Data Guard in the DR Type column when you select Disaster recovery under Resources. The provisioning process takes several minutes.
-
While you add a local standby database, when the Lifecycle State field shows Updating, the following actions are disabled for the primary database:
-
Move Resource. See Move an Autonomous Database to a Different Compartment for information on moving an instance.
-
Stop. See Stop Autonomous Database for information on stopping an instance.
-
Restart. See Restart Autonomous Database for information on restarting an instance.
-
Restore. See Restore and Recover your Autonomous Database for information on restoring.
