正在看的ORACLE教程是:oracle初始化参数设置。 ALTER DATABASE DATAFILEd:\ORANT\DATABASE\USER1ORCL.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
