Oracle sga allocation

ORACLE 8.0.XSGA = (db_block_buffers * block size) + (shared_pool_size + large_pool_size + log_buffers) + 1 MBORACLE 8.1.XSGA = (db_block_buffers * block size) + (shared_pool_size + large_pool_size + java_pool_size + log_buffers) + 1 MBIn theory, SGA accounts for 1/2 of the OS physical memory-1/3. We can adjust it as needed.I recommend SGA = 0.45 * (OS RAM)Assume that the server runs ORACLE 8.1.X, the OS memory is 2 GB MEM, and db_block_size is 8192 bytes,Except for running ORACLE databases, ther
