正在看的ORACLE教程是:oracle初始化参数设置。ALTER DATABASE DATAFILE'd:ORANTDATABASEUSER1ORCL.ORA' RESIZE 1000M;

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
