在 RHEL5 上配置 Oracle 10g Data Guard

一、环境配置主库SID(ddd)Global Database Name(ddd)Service Name(ddd)Net Server Name(ddd)IP：192.168.0.102DB：Oracle Databa

一、环境配置
主库SID(ddd)
Global Database Name(ddd)
Service Name(ddd)
Net Server Name(ddd)
IP：192.168.0.102

DB：Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
OS：rhel5

备库SID(ddd)
Global Database Name(ddd)
Service Name(ddd)
Net Service Name(dddsby)
IP：192.168.0.109

DB：Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
OS：rhel5

Primary为正在使用的生产数据库，standby安装oracle软件，，但不建立数据库。

二、 建立物理备用数据库
1． 准备主库的oracle环境：
编辑oracle用户的~oracle/.bash_profile文件，oracle相关环境变量如下：
export ORACLE_BASE=/oracle
export ORACLE_HOME=/oracle/product/10g
export ORACLE_SID=ddd
export PATH=$ORACLE_HOME/bin [点击图片可在新窗口打开] PATH
export TNS_ADMIN=$ORACLE_HOME/network/admin
export LANG=zh_CN
#export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export NLS_LANG=”SIMPLIFIED Chinese_CHINA.ZHS16GBK”

2． 修改主库为归档模式
建立归档目录：
mkdir -p /oracle/oradata/arch
修改归档模式：
alter database force logging;
archive log list;
create pfile from spfile;
编辑$ORACLE_HOME/dbs/initddd.ora
主库文件配置如下 [点击图片可在新窗口打开] 红色部分为要修改的参数)
