I am rying to change my backup to go directly to tape and
I am encountering the error below. Has anybody see this
type of error before and if so how can it be fixed?

Is RMAN trying to load a shared library?

Thanks to all who answer

Thanks, it sounded like I was missing a shared library but
was not 100% sure since this is my first time setting this up.

You have to buy the MML for your tape management software.
In your case, it is TDPO (Tivoli Data Protection for Oracle). Ask your IBM contact.
With it comes a manual that gives you how to create the shared library and to link it with RMAN.

I found the problem for those of you who are interested


My LD_LIBRARY_PATH was set like this:

echo $LD_LIBRARY_PATH
/u01/app/oracle/product/11g/lib:/u01/app/oracle/product/11g/rdbms/lib

Therefore it could not find the libobk.a library.. So I created
a link in $ORACLE_HOME/lib to point to the actual library.

$ pwd
/u01/app/oracle/product/11g/lib


$ ls -tlr libobk.a
lrwxrwxrwx    1 root     system           17 Nov 14 13:02 libobk.a -> /usr/lib/libobk.a
