　　INITORAL.ORA配置:

　　SGA=db_block_buffers*db_block_size+share_pool_size+log_buffers+sort_arer_size+1m

　　=1/3--1/2

　　以128M为例:

　　DB_BLOCK_BUFFERS=16000(db_block_size=2k)

　　SHARE_POOL_SIZE=30720000(服务器要增大10倍)

　　LOG_BUFFERS=655360

　　SORT_AREA_SIZE=327680(服务器要增大100倍)----------添加

　　GLOBAL_NAME=FALSE

　　ROLLBACK_SEGEMENTS=(RB1,RB2)//一般大型数据库要建立6-8个回滚段

　　添加:

　　DML_LOCKS=1000

　　OPEN_CURSORS=200
