Time for action – changing the protection mode with Data Guard broker

Now execute the following steps in order to use Data Guard broker commands for changing the Data Guard protection mode:

1. We now have Maximum Performance as the default protection mode in our configuration. Let's check it through DGMGRL. We can connect the interface from the primary or standby as follows:

   $ dgmgrl
   DGMGRL for Linux: Version 11.2.0.1.0 - 64bit Production

   Welcome to DGMGRL, type "help" for information.
   DGMGRL> CONNECT /
   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

2. Try to convert the configuration from Maximum Performance to the Maximum Availability mode as shown in the following command line:

   DGMGRL> EDIT CONFIGURATION SET PROTECTION MODE AS MaxAvailability;
