Time for action – switchover with a logical standby using broker

Perform the following steps to change the roles of the primary and logical standby databases:

1. Check the configuration of Data Guard. In the broker's configuration, we have one primary database and one logical standby database already configured. Ensure that the status is SUCCESS before performing a switchover as shown in the following code:

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

2. Perform a switchover using the DGMGRL command. Before performing switchover, connect to the DGMGRL utility using the complete username and password of the SYS user instead of connecting with / as shown in the following code:

   DGMGRL>  connect sys/*******
   Connected.

   Once authenticated, initiate the switchover with the following command as shown in the screenshot...
