In previous database releases, a database administrator (DBA) was required to
manually specify different SGA component sizes by setting a number of initialization
parameters, including the SHARED_POOL_SIZE , DB_CACHE_SIZE , JAVA_POOL_
SIZE, and LARGE_POOL_SIZE parameters. Oracle Database 10g includes the
automatic shared memory management feature which simplifies the SGA memory

various subcomponents to ensure mo st effective memory utilization.
