Time for action – enabling Active Data Guard using broker

If Data Guard is managed using a broker, it is always simple and even easier to manage it from Oracle 11gR2. When both broker and MRP are running on the standby, you can open the database at any time for reporting purposes.

1. Check the configuration and state of the database 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
   DGMGRL>
   
   SQL> select db_unique_name,open_mode from v$database;
   DB_UNIQUE_NAME  OPEN_MODE
   --------------- --------------------
   INDIA_UN        MOUNTED
   SQL>
   SQL> !ps -ef|grep mrp
   oracle    4686     1  0 16:31 ?        00:00:00 ora_mrp0_INDIA
   oracle    4815  3948  0 16:35 pts/1    00:00:00 /bin/bash -c ps -ef|grep mrp
   Open Database for the use of Active Data Guard
   SQL> alter database open read only;
