今天试了一下在10g rac下改IP,下文为wj整理的:

环境：

OS：Red Hat Linux AS4
DB：10gR2 RAC
 

测试内容：

RAC1上：
公网IP由：
134.96.39.188      rac1
更改为：
134.98.83.58      rac1
 
VIP地址由：
134.96.39.186        rac1-vip
更改为
134.98.83.242        rac1-vip
 
RAC2上：
公网IP由：
134.96.39.189       rac2
更改为：
134.98.83.59        rac2
 
VIP地址由：
134.96.39.187           rac2-vip
更改为：
134.98.83.243       rac2-vip
 

1、停CRS

[oracle@rac1 bin]$ crs_stat -t
Name          Type          Target   State    Host

[oracle@rac1 bin]$ crs_stop -all

[oracle@rac1 bin]$ ps -ef|grep pmon
oracle  30354 21199 0 14:01 pts/3   00:00:00 grep pmon
[oracle@rac1 bin]$
 

2、修改两台机器的/etc/hosts文件

以下是修改后的结果：
[oracle@rac1 ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1      localhost
134.98.83.57   rac1.oraclefocus.com   rac1
134.98.83.242  rac1-vip.oraclefocus.com       rac1-vip
#10.1.9.212   rac1.oraclefocus.com   rac1
#10.1.9.242   rac1-vip.oraclefocus.com       rac1-vip
10.10.10.31    rac1-priv.oraclefocus.com      rac1-priv
134.98.83.58   rac2.oraclefocus.com   rac2
134.98.83.243  rac2-vip.oraclefocus.com       rac2-vip
#10.1.9.213   rac2.oraclefocus.com   rac2
#10.1.9.243   rac2-vip.oraclefocus.com       rac2-vip
10.10.10.32    rac2-priv.oraclefocus.com      rac2-priv
 

3、修改listener.ora文件

 

4、在系统设置中修改网卡eth0的IP，子网掩码，网关，并重新激活

以RCA1上为例，将eth0的相关IP更改如下
原：IP：10.1.9.212   子网掩码：255.255.255.0   网关：10.1.9.1
新：IP：134.98.83.57 子网掩码：255.255.255.224 网关：134.98.83.1
 
这里需要注意，若原eht1无子网掩码，需要加上，设成:10.10.10.1，否则一些CRS服务无法启动
开始没有加上,发现只有少数几个起来了,加上后就可以正常启动了
 
 

5、更改PUBLIC网卡设置

以ROOT用户执行
[root@rac1 bin]# pwd
/u01/app/oracle/product/10.2.0/crs_1/bin
[root@rac1 bin]#
[root@rac1 bin]# ./oifcfg getif
eth0 10.1.9.0 global public
eth1 10.10.10.0 global cluster_interconnect
[root@rac1 bin]#
 

5.1删除原的PUBLIC网卡设置

[root@rac1 bin]# ./oifcfg delif -global eth0
[root@rac1 bin]# ./oifcfg getif
eth1 10.10.10.0 global cluster_interconnect
[root@rac1 bin]#
 

5.2设置新PUBLIC网卡地址

[root@rac1 bin]# ./oifcfg setif -global eth0/134.98.83.0:public
[root@rac1 bin]# ./oifcfg getif
eth0 134.98.83.0 global public
eth1 10.10.10.0 global cluster_interconnect
[root@rac1 bin]#
 

6、更改VIP配置

在两个节点上分别运行：
[root@rac1 bin]# ./srvctl modify nodeapps -n rac1 -A 134.98.83.232/255.255.255.224/eth0
[root@rac1 bin]# ./srvctl modify nodeapps -n rac2 -A 134.98.83.233/255.255.255.224/eth0
 

7、重启CRS

[root@rac1 bin]# ./crs_start -all
[root@rac1 bin]# ./crs_stat -t
Name          Type          Target   State    Host
------------------------------------------------------------
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
ora.racdb.db    application   ONLINE   ONLINE   rac2
ora....d1.inst application   ONLINE   ONLINE   rac1
ora....d2.inst application   ONLINE   ONLINE   rac2
 
[root@rac1 bin]# ps -ef|grep pmon
oracle  25377    1 0 16:46 ?       00:00:04 asm_pmon_+ASM1
oracle  25980    1 0 16:47 ?       00:00:04 ora_pmon_racdb1
root    12077 28069 0 17:41 pts/3   00:00:00 grep pmon
 
[root@rac2 bin]# ps -ef|grep pmon
oracle  31746    1 0 17:14 ?       00:00:02 asm_pmon_+ASM2
oracle   7051    1 0 17:22 ?       00:00:02 ora_pmon_racdb2
root    24145 24109 0 17:41 pts/3   00:00:00 grep pmon
至此，IP修改完成
