Reinstate a Database

This topic describes how to reinstate a failed database as a standby database in a Data Guard group using Oracle Base Database Cloud@Customer.

Before you begin, review the following:

• After you fail over a primary database to its standby database, the standby database assumes the primary role, and the former primary database is marked as a disabled standby.

• After you fix the cause of the failure, you can reinstate the former primary database as the standby database for the current primary database.

Before you begin, perform the following steps:

• on the database host, stop the database and start it in MOUNT mode:

  srvctl stop database -d db-unique-name -o abort
  srvctl start database -d db-unique-name -o mount

Procedure

Perform the following steps in the Console.

1. On the Data Infrastructures list page, select the Data Infrastructure that you want to work with. If you need help finding the list page or the Data Infrastructure, see List Data Infrastructures.

2. On the Data Infrastructure details page, select the VM Cluster tab to view the list of all VM Clusters.
3. On the VM Clusters tab, select the VM Cluster that you want to work with.

4. On the VM Cluster details page, select the Databases tab to view the list of all databases.

5. On the Databases tab, select the Database that you want to work with.

6. On the Database details page, select Data Guard Group.

7. For the database you want to reinstate, from the Actions menu, select Reinstate.

8. In the Reinstate database panel, enter the database administrator password, and then select Ok.

After the operation completes successfully, the database is reinstated as the standby database in the Data Guard Group.
