After executing a backup on standby site, sometimes, the snapshot controlfile is changed to the primary site configuration and next backup fails with:
RMAN error stack as below
RMAN-03009: failure of Control File and SPFILE Autobackup command on c1 channel at 05/22/2012 02:30:08
ORA-01580: error creating control backup file +DATA/gmfcdwp_tel/controlfile/snapcf_gmfcdwp.f
ORA-17502: ksfdcre:4 Failed to create file +DATA/gmfcdwp_tel/controlfile/snapcf_gmfcdwp.f
ORA-15173: entry 'gmfcdwp_tel' does not exist in directory '/'
Here DB_UNIQUE_NAME of primary DB is gmfcdwp_tel and DB_UNIQUE_NAME of standby is gmfcdwp_lvt.
Backups ran fine using catalog from standby site but sometimes while taking snapshot controlfile it fails saying directory doesn't exist .
