Identify the memory component from which memory may be allocated for:
Session memory for the shared serverBuffers for I/O slavesOracle Database Recovery Manager
(RMAN) backup and restore operations
A.
Large Pool
B.
Redo Log Buffer
C.
Database Buffer Cache
D.
Program Global Area (PGA)
The large pool is an optional area that, if created, will be used automatically by
various processes that would otherwise take memory from the shared pool.One
major use of the large pool is by shared server processes, . Parallel execution servers will
also use the large pool. In the absence of a large pool, these processes will use memory on the shared pool. This can cause bad contention for the shared pool: if shared servers or parallel servers are being used, a large pool should always be created. Some I/O processes may also make use of the large pool, such as the processes used by the Recovery Manager when it is backing up to a tape device
