Large Pool is an optional memory structure used for the following purposes :-
(1) Session information for shared server
(2) I/O server processes
(3) Parallel queries
(4) Backup and recovery if using through RMAN.
The role of Large Pool is important because otherwise memory would be allocated from the Shared pool. Hence Large pool also reduces overhead of Shared pool.
