How to Switchover From Primary Database to Standby database by Data Guard Broker using DGMGRL| Switchback from Standby Database to Primary Database.

A database can be in one of two mutually exclusive modes (primary or standby). These roles can be altered at runtime without loss of data or resetting of redo logs. This process is known as a Switchover.

You can switch a database from the primary role to the standby role, as well as from standby to primary. This is known as a database switchover, because the standby database that you specify becomes the primary database, and the original primary database becomes a standby database. There is no loss of data, the data is consistent between the original primary database and the new primary database after the switchover completes.
