Oracle Cloud (DBaaS): Oracle Data Guard in Database Cloud Service ( DBCS )
Now in this this article we will show the necessary steps to perform Switchover, Failover & Reinstate Operations with the DBCS Console.
Performing a Switchover Operation
A switchover operation enables the primary database to switch roles with its standby database. There is no data loss during a switchover. After a switchover, each database continues to participate in the Oracle Data Guard configuration in its new role. A switchover is typically used to reduce primary database downtime during planned outages, such as operating system or hardware upgrades, or rolling upgrades of the Oracle database software and patch sets.
