1、首先确认RAC两个节点都能正常启动,并且各个服务online.
[root@rac2 ~]# crs_stat -t
Name Type Target State Host
------------------------------------------------------------
ora.devdb.db application ONLINE ONLINE rac2
ora....b1.inst application ONLINE ONLINE rac1
ora....b2.inst application ONLINE ONLINE rac2
ora....SM1.asm application ONLINE ONLINE rac1
ora....C1.lsnr application ONLINE ONLINE rac1
ora.rac1.gsd application ONLINE ONLINE rac1
ora.rac1.ons application ONLINE ONLINE rac1
ora.rac1.vip application ONLINE ONLINE rac1
ora....SM2.asm application ONLINE ONLINE rac2
ora....C2.lsnr application ONLINE ONLINE rac2
ora.rac2.gsd application ONLINE ONLINE rac2
ora.rac2.ons application ONLINE ONLINE rac2
ora.rac2.vip application ONLINE ONLINE rac2
[root@rac2 ~]#
2、使用srvctl stop依此停止数据库，app，asm ，注意不能用crsctl stop crs 停crs的服务。
[root@rac2 ~]# su - oracle
rac2->
rac2->
rac2-> srvctl stop database -d devdb
rac2-> srvctl stop nodeapps -n rac1
rac2-> srvctl stop nodeapps -n rac2
rac2-> srvctl stop asm -n rac1
rac2-> srvctl stop asm -n rac2
rac2-> crs_stat -t

rac2->
确认OCR中的配置接口
rac2-> oifcfg getif
eth0 192.168.2.0 global public
eth1 10.10.21.0 global cluster_interconnect
rac2->
修改OCR中的public IP
rac2-> oifcfg delif -global eth0
rac2-> oifcfg getif
eth1 10.10.21.0 global cluster_interconnect
rac2-> oifcfg setif -global eth0/192.168.11.0:public
rac2-> oifcfg getif
eth0 192.168.11.0 global public
eth1 10.10.21.0 global cluster_interconnect
rac2->
修改完毕。
rac2-> exit
[root@rac2 ~]# crsctl stop crs
Stopping resources. This could take several minutes.
Successfully stopped CRS resources.
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
[root@rac2 ~]#
[root@rac1 ~]# crsctl stop crs

[root@rac1 ~]#
改IP的时候主机可能会自动重启。
修改listener.ora
启动CRS并检查
[root@rac1 ~]# df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 2925300 2264168 512536 82% /

/dev/sda2 4293444 2500956 1618024 61% /u01
[root@rac1 ~]#
发现 ocfs 不能mount.
#ocfs2console
Configure node查看。发现IP地址还没有更改。
修改2台主机的/etc/ocfs2/cluster.conf
[root@rac2 ~]# cat /etc/ocfs2/cluster.conf
node:
ip_port = 7777
ip_address = 192.168.11.131
number = 0
name = rac1
cluster = ocfs2
node:
ip_port = 7777
ip_address = 192.168.11.132
number = 1
name = rac2
cluster = ocfs2
cluster:
node_count = 2
name = ocfs2
[root@rac2 ~]#
在两台主机上执行：
[root@rac2 ~]# /etc/init.d/o2cb unload

This will configure the on-boot properties of the O2CB driver.
The following questions will determine whether the driver is loaded on
boot. The current values will be shown in brackets ('[]'). Hitting
<ENTER> without typing an answer will keep that current value. Ctrl-C
will abort.

[root@rac2 ~]# srvctl modify nodeapps -n rac2 -A 192.168.11.32/255.255.255.0/eth0
启动后修改正常。
