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為例：
db_block_buffers=16000（db_block_size=2k）
share_pool_size=30720000(服務器要增大10倍)
log_buffers=655360
sort_area_size=327680(服務器要增大100倍)－－－－－－－－－－添加
global_name=false
rollback_segements=(rb1,rb2)//一般大型數據庫要建立6－8個回滾段
添加：
dml_locks=1000
open_cursors=200
