Yes, you will need to restart the oracle processes. The library is
loaded during startup.

        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
