Oracle 10g RAC 添加节点

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

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

# 
# An example would be:

# to bind /dev/raw/raw1 to /dev/sda, or 
#  ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"
