When protecting Oracle databases with PowerProtect Data Manager, the system utilizes a dedicated RMAN Agent installed on the Oracle server. This agent facilitates the communication between Oracle's Recovery Manager (RMAN) and the PowerProtect DD storage system via the DD Boost protocol.
Installation Path: By default, the PowerProtect Data Manager RMAN agent is installed in the
/opt/dpsapps/rmanagent directory on Linux/Unix systems.
The Library File: The DD Boost library file (typically named libddobk.so on Linux or libddobk.dll on Windows) is the interface that RMAN calls to send data to the protection storage.
Environment Variables: In the RMAN script, the SBT_LIBRARY parameter must point to the location of this file. Within the PPDM environment, the directory is referenced using the variable
$RMAN_AGENT_HOME/lib.
Ensuring that the RMAN script correctly points to this path is essential for the "SBT_TAPE" device type to initialize correctly and establish a session with the PowerProtect DD.
