Description:

Session #1 is an initial session, mainly used for starting the RMAN command and getting a status of Oracle with session #5.

Session #2 is a job control session under Oracle SBT (Serial Backup Tape) library, which starts actual data transfer and checks catalog information. When a backup job is initiated from the RMAN command instead of the Media Server, this session becomes an initial session instead of session #1.

Session #3 and #4 are actual data transfer sessions using the Network Data Management Protocol (NDMP) between the Media Server and the Oracle SBT library. NDMP uses two sessions, session #3 is a control session and session #4 is a data transfer session.
