ORA-27211: Failed to load Media Management Library

CAUSE
The problem is an environment problem. When the LD_LIBRARY_PATH is set and the vendors libobk is a part of that path when a channel is allocated within RMAN the library should dynamically load from the channels initialization call. This is not always the case and is known to Tivoli.
Tivoli has provided the following solution to this issue.
SOLUTION
This example is for an AIX platform.
To resolve this:
1) Link the TDP library file directly to the Oracle directory. The link would look like:
$ORACLE_HOME/lib/libobk.a -> /usr/tivoli/tsm/client/oracle/bin64/libobk64.a
2) Change the LIBPATH environment variable to include $ORACLE_HOME/lib before /usr/lib. If you have a LD_LIBRARY_PATH, ensure that this has the $ORACLE_HOME/lib before /usr/lib.
3) Ensure the SBT_LIBRARY parameter is not set
4) The Oracle instance may need to be restarted as it has been seen where the LIBPATH value was held in memory.
