What is the tape backup client that you are using. Is it Legato or Tivoli or what?


Try this:

Shutdown all oracle instances.

rm $ORACLE_HOME/lib/libobk.so

On the above it is called so for shared object on Solaris.
Similarly figure out the object on HP

ln -s /usr/lib/libobk.so $ORACLE_HOME/lib/libobk.so

Restart all the instances.


If your tape client is some third party one then you might have to pass some parameters. Check your manual.


For example: on Tivoli Data Protection for oracle, you have to specify some environment variables for it to get to the tape drive.

Good luck,
