Oracle Error Description

ORA-00245: control file backup failed; target is likely on a local file system

Reason for the Error ORA-00245: control file backup failed; target is likely on a local file system

Failed to create a control file backup because some process signaled an error during backup creation. This is likely caused by the backup target being on a local file system so it could not be accessed by other instances. It can also be caused by other I/O errors to the backup target. Any process of any instance that starts a read/write control file transaction must have access to the backup control file during backup creation.
