修改10g RAC public or private or virtual IP [Oracle]

首先启动HACMP,smit clstart

#su - oracle

rac2-> oifcfg getif
en0 192.168.192.0 global public
en1 10.10.10.0 global cluster_interconnect

rac1-> oifcfg getif
en0 192.168.192.0 global public
en1 10.10.10.0 global cluster_interconnect
修改操作只需在一台主机上进行。

rac1-> oifcfg delif -global en1
rac1-> oifcfg getif
en0 192.168.192.0 global public
rac1-> oifcfg setif -global en1/10.10.21.0:cluster_interconnect
rac1-> oifcfg getif
en0 192.168.192.0 global public
en1 10.10.21.0 global cluster_interconnect
在rac1上修改后，在rac2上查看ip地址，已经被修改过。

rac2-> oifcfg getif
en0 192.168.192.0 global public
en1 10.10.21.0 global cluster_interconnect
rac2->

1.确认OCR中的配置接口
[oracle@rac1 ~]$ oifcfg getif
eth0 192.168.163.0 global public
eth1 10.10.10.0 global cluster_interconnec

2.修改OCR中的public IP
[oracle@rac1 ~]$ oifcfg delif -global eth0
[oracle@rac1 ~]$ oifcfg setif -global eth0/192.168.11.0:public
[oracle@rac1 ~]$ oifcfg getif
eth0 192.168.11.0 global public
eth1 10.10.10.0 global cluster_interconnect

3.修改OCR中的private IP
[oracle@rac1 ~]$ oifcfg delif -global eth1
[oracle@rac1 ~]$ oifcfg setif -global eth1/10.10.21.0:cluster_interconnect
[oracle@rac1 ~]$ oifcfg getif
eth0 192.168.11.0 global public
eth1 10.10.21.0 global cluster_interconnect

4.修改各node的IP和/etc/hosts
rac1
192.168.11.11/255.255.255.0/192.168.11.10
10.10.21.11/255.255.255.0

rac2
192.168.11.12/255.255.255.0/192.168.11.10
10.10.21.12/255.255.255.0

192.168.11.11 rac1
192.168.11.12 rac2
10.10.21.11 rac1_priv
10.10.21.12 rac2_priv
192.168.11.31 rac1_vip
192.168.11.32 rac2_vip

5.修改listener.ora

6.启动CRS并检查
[root@rac1 ~]# /etc/init.d/init.crs start
Startup will be queued to init within 90 seconds.

[root@rac2 ~]# /etc/init.d/init.crs start
Startup will be queued to init within 90 seconds.

[oracle@rac1 ~]$ crsctl check boot

[oracle@rac1 ~]$ crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy

7.修改VIP IP
[oracle@rac1 ~]$ srvctl stop database -d racdb
注：从10.2.0.3开始 VIP与database or asm 没有依赖关系

[oracle@rac1 ~]$ srvctl stop nodeapps -n rac1
[oracle@rac1 ~]$ srvctl stop nodeapps -n rac2

[root@rac1 bin]# ./srvctl modify nodeapps -n rac1 -A 192.168.11.31/255.255.255.0/eth0
[root@rac1 bin]# ./srvctl modify nodeapps -n rac2 -A 192.168.11.32/255.255.255.0/eth0

8.启动相关资源
[oracle@rac1 ~]$ srvctl start nodeapps -n rac1
[oracle@rac1 ~]$ srvctl start nodeapps -n rac2
[oracle@rac1 ~]$ crs_start ora.racdb.db
Attempting to start `ora.racdb.db` on member `rac1`
Start of `ora.racdb.db` on member `rac1` succeeded.
[oracle@rac1 ~]$ crs_stat -t
Name Type Target State Host
