Restore a primary RAC using backup taken from physical standby RAC

 Hi,

 I would restore a primary RAC using backup taken from physical standby RAC .

According to doc, backup of datafile, control file in 11.2 should be interchangeable.

Does anyone have real experience about this case?

My proposed procedure is listed as following.

Any comment/suggestion would be much appreciated.

Thanks

Regards

Thomas

Procedure

Backup standby database:

rman target / 

set controlfile autobackup format for device type disk to "+FRADG";

backup database format "+FRADG" plus archivelog format "+FRADG" delete input;

Verify the backup

list backupset of database;

Switch the current log in primary database 

alter system archive log current; -- For RAC, just need to run on 1 node
