Time for action – switchover with a physical standby using broker

1. If the primary database is RAC and you perform switchover with the broker, it will shut down all the remaining instances except one; and if there are any issues in terminating the instances, the switchover will exit without success. So ensure that all the primary instances are down except the one.

2. Even though the broker will verify the state of the both the primary and standby databases, it's recommended to check the database state manually as follows:

   DGMGRL> show configuration;
   Configuration - PACKT
     Protection Mode: MaxPerformance
     Databases:
       turkey_un - Primary database
       INDIA_UN  - Physical standby database
   Fast-Start Failover: DISABLED
   Configuration Status:
   SUCCESS
   

3. Now connect to the DGMGRL and issue the command as shown in the following screenshot:

   

   Tip

   When performing a switchover, connect the database to the DGMGRL using a complete password such as connect sys/******, because DGMGRL doesn't support OS authentication...
