ORA-16789: Standby Redo Logs Not Configured

This is very common error which occur during the switchover the standby database in Dataguard Broker. In my case when i switchover to standby the error occur as below : 

C:\>dgmgrl
DGMGRL for 32-bit Windows: Version 11.2.0.1.0 - Production
Copyright (c) 2000, 2009, Oracle. All rights reserved.
Welcome to DGMGRL, type "help" for information.

DGMGRL> connect sys/xxxx@noida
Connected.

DGMGRL>  switchover to 'red';
Performing switchover NOW, please wait...
Error: ORA-16789: standby redo logs not configured
Failed.
Unable to switchover, primary database is still "noida"

This error generally occur because the Standby redo logs were not configured for the database.

Therefore,Standby redo logs are required when the redo transport mode is set to SYNC or ASYNC . Hence to solve this we have add standby redolog files on primary database . Below the command to this issue. 

On Primary Database: 

SQL> ALTER DATABASE add standby  LOGFILE GROUP 6  'C:\APP\NEERAJS\ORADATA\NOIDA\REDO06.LOG' size 50m ;
Database altered.

Now it's is not giving any further error .


Enjoy         :-)
