Hi Matthew, I suspect that the libobk.so file is there as Netbackup was being 
used previosuly to backup this server so perhaps netbackup placed the file 
there. 
   
  I have renamed the file and then created the link required by networker. When 
i attempt to run a backup i get as far as the RMAN script and the backup fails 
with an error of "ORA-27211: Failed to load Media Management Library". 
   
  I have also tried initiating each command using RMAN rather than a networker 
scheduled backup but i receive the same error.
   
  Do you think that the incorrect libobk.so is loaded in memory by netbackup 
and therefore the link to the networker libobk.so is not being used and the 
incorrect library is being loaded?
   
  Do you think that a restart of the Oracle services will resolve this? 
   
  Thanks again, Mark

If you have oracle processes currently running then it can create
problems. If you can shut down the oracle proccesses, just remove the
file and create the link. 

It's possible that someone create a hardlink rather than a softlink (ln
rathern than ln -s) which means the file is referenced directly from
both locations. This can only happen if the oracle software is installed
on the same volume as /usr/lib.

Subject: [Networker] Oracle module file libobk.so already exists

Hi, i have just installed the oracle 4.5 module on a solaris 9 64 bit
server running oracle 9.2 32 bit. I have just tried to create the link
from /usr/lib/libnwora.so to libobk.so (located in the oraclehome/lib
directory).

The libobk.so file already exists so my link creation has failed. The
existing libobk.so file is not a link. I am not sure how this file got
there and if i can remove it. Can i remove this file from this directory
and then create the link? 

Thanks, Mark
