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
