Reinstate the failed Primary as Standby Using Broker (DGMGRL)

How to Reinstate the failed Primary as Standby Using Broker (DGMGRL)- Without Rebuilding

Set the correct environment and issue the following command while connected to any database in the broker configuration, except the database that is to be reinstated:

DGMGRL> REINSTATE DATABASE db_unique_name;

The newly reinstated standby database will begin serving as a standby database to the new primary database.

Note:- Flashback must be on and Flashback logs must be accessible for the REINSTATE to succeed. If your database was in no flashback mode before the failover you need to rebuild it manually from current primary

DGMGRL> REINSTATE DATABASE APX1TP;
Reinstating database "APX1TP", please wait...
Oracle Clusterware is restarting database "APX1TP" ...
Continuing to reinstate database "APX1TP" ...
Reinstatement of database "APX1TP" succeeded

DGMGRL> show configuration;

How to Switch Log File from All Instances in RAC

<<Back to Oracle RAC Main Page Switch The Log File of All Instances in Oracle RAC. In many cases you need to switch the logfile of the database.

You can avoid this and switch logfile of all instances by just running the below command from any of the instance in RAC database SQL> ALTER SYSTEM SWITCH ALL LOGFILE; System altered.
