1.禁止相关CRS资源的启动,停止这些资源(vip,listener,scan,scan_listener,database)1.1 所有节点上禁止数据库启动,停止数据库

1.禁止相关CRS资源的启动,停止这些资源(vip,listener,scan,scan_listener,database)

1.1  所有节点上禁止数据库启动,停止数据库

[grid@rac1 ~]$ srvctl disable database -d racdb

[grid@rac1 ~]$ srvctl stop database -d racdb

1.2  禁止所有节点的LISTNER的启动,停止所有节点上的LISTENER

[grid@rac1 ~]$ srvctl disable listener

[grid@rac1 ~]$ srvctl stop listener

1.3  禁止所有节点的VIP的启动,停止所有节点上的VIP(注意:a.操作VIP的时候提供的/etc/hosts中配置的是VIP的名字;b.只有root用户才能DISABLE VIP资源)

[root@rac1 ~]# /u01/app/11.2.0/grid/bin/srvctl disable vip -i "rac1-vip"

[root@rac1 ~]# /u01/app/11.2.0/grid/bin/srvctl disable vip -i "rac2-vip

[grid@rac1 ~]$ srvctl stop vip -n rac1

[grid@rac1 ~]$ srvctl stop vip -n rac2

1.4  禁止所有节点的SCAN_LISTENER的启动,停止所有节点上的SCAN_LISTENER

[grid@rac1 ~]$ srvctl disable scan_listener

[grid@rac1 ~]$ srvctl stop scan_listener

1.5  禁止所有节点的SCAN的启动,停止所有节点上的SCAN

[root@rac1 ~]# /u01/app/11.2.0/grid/bin/srvctl disable scan

[grid@rac1 ~]$ srvctl stop scan

2.网络基础设施配置(交换机,路由器,,DNS)

这里要保证主机配置更改好能能够正长访问网络资源,DNS服务器中的相关条目要反映新的IP

3.操作系统网络配置修改(/etc/hosts,ifcfg-eth0,/etc/resolve.conf)

4.CRS 网络相关资源的重新配置和启动(集群的public网络和网卡设置,vip配置和LISTENER得启动,scan的重新配置和SCAN_LISTENER的启动)

第3步操作完成,配置生效后才能进行下面的操作;另外public ip,vip 不需要特别的配置,修改完/etc/hosts文件中的对应条目后

集群回自动使用新的IP,Oracle应该主要使用主机名来配置这些IP的;
