目前环境是一个版本为oracle 10.2.0.5的双节点rac,hostname分别为racnode1,racnode2需要添加新节点racnode3。

os版本是oracle linux 5.7 x86_64
保证rac正常运行
配置public ip,private ip,vip,将这些信息配置到/etc/hosts文件中
192.168.1.51 racnode1
192.168.1.151 racnode1-vip
172.168.1.51 racnode1-priv
192.168.1.52 racnode2
192.168.1.152 racnode2-vip
172.168.1.52 racnode2-priv
192.168.1.53 racnode3
192.168.1.153 racnode3-vip
172.168.1.53 racnode3-priv
安装相关的rpm包,配置系统内核参数,我这里使用的是oracle linux5提供的的oracle-validated包进行安装配置
[root@racnode3 ~]# yum -y install oracle-validated
loaded plugins: rhnplugin, security
this system is not registered with uln.
uln support will be disabled.
setting up install process
package oracle-validated-1.1.0-15.el5.x86_64 already installed and latest version
同步各节点的时间,我这里使用的是ntp服务
[root@racnode3 ~]# crontab -l
*/5 * * * * /usr/sbin/ntpdate 0.asia.pool.ntp.org > /dev/null 2>&1
配置共享磁盘
