Oracle 19c backup fails : ORA-00245: control file backup failed; in Oracle RAC, target might not be on shared storage

 

Error:

ORA-00245: control file backup failed; in Oracle RAC, target might not be on shared storage

Solution:

Enable shared control file:

1.    Configure the snapshot controlfile to a shared disk like (ACFS/NFS/DNFS):

RMAN> CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/SHARED_Folder/snapcf_KRISHNA.f';

2.    In case of ASM use

RMAN> CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+ASM_DATA/snapcf_CNTRL.f';
