Cause: The secondary database that your instance is
attempting to mount is not open and automatic mounting has
not been enabled.

Action: Manually mount and open the secondary database using
ALTER DATABASE <linkname> with the OPEN and MOUNT options.
Alternately, to allow your instance to automatically mount
and open secondary databases, set the AUTO_MOUNTING
parameter in the parameter file to TRUE.
