  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
