The shared pool in the SGA consists of a library cache, a dictionary cache (Dictionary cache), a buffer for parallel execution messages, and a control structure. The size of the Shared POOL is determined by the parameter shared_pool_size. 9i, the default value of this parameter is 8M under 32-bit system, and the default value of 64-bit system is 64M. The maximum is 4G. 10g can be adjusted automatically by Sga_target parameters. Memory management for
