An Oracle administrator is preparing a RMAN recover script using PowerProtect Data Manager. What is the default installation location of the DD Boost library file?

When integrating PowerProtect Data Manager with Oracle RMAN, the DD Boost library file (libddobk.so or ddobk.dll) is required for communication. The PowerProtect Oracle RMAN agent installation creates a specific directory structure. The default environment variable pointing to this installation root is $RMANAGENTHOME. The library file itself is located within the lib subdirectory of this home directory. Therefore, the correct path specified in RMAN scripts is $RMANAGENTHOME/lib.

A. $ORACLEHOME/lib is the location for Oracle's native libraries, not for third-party components like the DD Boost agent library.
C. $RMANAGENT/lib is an incorrect and non-standard environment variable. The officially documented variable includes HOME.
D. $ORACLEAGENTHOME/lib is not the standard environment variable used for the PowerProtect RMAN agent installation directory.
