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
