Switchover_status is not allowed in standby

Hi folks,

i have configured standby database for oracle 11g (11.2.0.1.0) on AIX 6.1 .i have not check the switch over or failover , as the primary database is Production

but when i checked

@Primary side:

SQL> select switchover_status from v$database;

SWITCHOVER_STATUS
--------------------
TO STANDBY

SQL> select max(sequence#) from v$archived_log where applied='YES';


MAX(SEQUENCE#)
--------------
2563

@Standby Side


SQL> select switchover_status from v$database;


SWITCHOVER_STATUS
--------------------
NOT ALLOWED


SQL> select max(sequence#) from v$archived_log where applied='YES';


MAX(SEQUENCE#)
--------------
2563


but i google about SWITCHOVER_STATUS is NOT ALLOWED but it says
NOT ALLOWED - Either this is a standby database and the primary database has not been switched first, or this is a primary database and there are no standby databases.

i have checked the DR syn is fine ,RFS is working fine , archive are being applied on DR


so please let me know in future if business permits can i switch over and do the testing and switch back to primary with the same setting.

appreciate your prompt response .


Regards.

You should make sure that you have both online redo logs and standby redo logs.

switchover_status not allowed on the standby can be.
If you are sure logfiles are applied then switchover still be possible.
You should worry if the status ‘NOT ALLOWED’ would be not on the primary database as that would mean there are no other databases.
When I builded my production site I at the same time builded my standby dataguard. Before put it into production I tested the switchover several times. It worked although the status on the standby gives me ‘NOT ALLOWED’.
Most important things are:
Check the standby alertlog file if the archive log files are really applied. Media recovery has to take place.
Use the dataguard manager:
