一、环境概述
当前Oracle 11g RAC集群为两节点集群，现计划为该集群增加一个节点。
1.1 现有集群节点信息
1.2 新增节点信息
1.3 环境准备
系统设置：新增节点部署和原集群节点相同操作系统并完成网络等相关配置。
用户及属组：新增节点参照原集群节点创建相同用户及组
环境变量：新增节点参照原集群节点配置了oracle及grid用户环境变量
ASM存储：新增节点参照原集群节点配置多路径并配置了ASM磁盘
节点互信：新增节点oracle及grid用户已配置和原集群节点SSH互信
二、添加节点
2.1 验证新增节点配置
-- 以下操作在现有集群某节点操作，grid用户执行
[root@host210 ~]# su - grid
[grid@host210 ~]$ olsnodes -s -t
host210 Active Unpinned
host211 Active Unpinned
[grid@host210 ~]$ cluvfy comp peer -n host212
-- 上述命令输出结果如下
