RAC IP 但是它涉及到。OCR 稳定第一。在做之前，要手动的进行一个备份， OCRBlog和的备份与恢复

另外Public/PrivateCRS
实验平台：
一． 停止oracle相关的所有进程, 包括数据库, asm, node application, crs本身.
1.1
[root@raw1 bin]# ./crs_stat -t
------------------------------------------------------------
ora.raw.dmm.cs applicationOFFLINEOFFLINE

1.2
1.3 [root@raw1 bin]# ./srvctl stop asm -n raw1
1.4
[root@raw1 bin]# ./srvctl stop nodeapps -n raw2
1.5
[root@raw1 bin]# /etc/init.d/init.crs stop
Stopping resources.
Stopping CSSD.
Shutdown request successfully issued.
Shutting down Oracle Cluster Ready Services (CRS):
Successfully stopped CRS resources
Shutting down CSS daemon.
Shutdown has begun. The daemons should exit soon.
2.1 [root@raw1 bin]# vi /etc/hosts
# that require network functionality will fail.
10.85.10.221 raw2
192.168.1.221 raw2-priv
10.85.10.223 raw2-vip
在两个节点上分别修改eth0和eth1地址：
DEVICE=eth0
IPADDR=10.85.10.219
ONBOOT=yes
[root@raw2 ~]# more /etc/sysconfig/network-scripts/ifcfg-eth0
BOOTPROTO=static
NETMASK=255.255.255.0
GATEWAY=10.85.10.253
DEVICE=eth1
IPADDR=192.168.1.219
ONBOOT=yes
[root@raw2 ~]# more /etc/sysconfig/network-scripts/ifcfg-eth1
BOOTPROTO=static
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
2.3 [root@raw1 ~]# service network restart
在两个节点启动crs, 并关闭随crs启动的应用程序
/etc/init.d/init.crs start
[root@raw2 ~]#Startup will be queued to init within 90 seconds.
由于oracle所有应用设置为自动启动, 所以在crs启动时会试图启动所有的服务, 但是在对oracle相关的ip地址进行设置时需要crs处于运行状态. [root@raw1 bin]# ./srvctl stop asm -n raw2
[root@raw1 bin]# ./srvctl stop nodeapps -n raw1
[root@raw1 bin]# ./crs_stat -t
------------------------------------------------------------
ora.raw.dmm.cs applicationOFFLINEOFFLINE

ora.raw1.gsdapplicationOFFLINEOFFLINE
ora.raw1.vipapplicationOFFLINEOFFLINE
ora....W2.lsnr applicationOFFLINEOFFLINE
ora.raw2.onsapplicationOFFLINEOFFLINE
3.2 注： 如果修改的网段相同，可以不做这一步。
查看当前配置：
eth010.85.10.0globalpublic
[root@raw1 bin]# ./oifcfg delif -global eth0
[root@raw1 bin]# ./oifcfg getif
重新添加
10.85.10.0:public
192.168.1.0:cluster_interconnect
eth010.85.10.0globalpublic
[root@racnode2 bin]# ./oifcfg iflist
eth1192.168.0.0
eth3192.168.200.0
eth5192.168.200.0
这里地址最一个为代表的是一个网段。否在在启动时网络地址和网络接口操作中出错 [7]
修改VIP
[root@raw1 bin]# ./srvctl modify nodeapps -n raw2 -A 10.85.10.223/255.255.255.0/eth0
3.4 [root@raw1 bin]# vi/u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
/u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora.raw1
LISTENER_RAW1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =)
注意：如果你使用了ocfs，修改ocfs配置文件(/etc/ocfs/cluster.conf),验证修改后是否可用。
3.5 [root@raw1 bin]# ./srvctl start nodeapps -n raw1
[root@raw1 bin]# ./srvctl start asm -n raw1
[root@raw1 bin]# ./srvctl start instance -d raw -i raw1
[root@raw1 bin]# ./crs_stat -t
