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。

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

[root@racnode3 ~]# cat /etc/udev/rules.d/60-raw.rules

# An example would be:
# ACTION==”add”, KERNEL==”sda”, RUN+=”/bin/raw /dev/raw/raw1 %N”
# 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”
# to bind /dev/raw/raw2 to the device with major 8, minor 1.
