oracle10g rac 零宕机修改public ip&vip

浏览数：30 / 时间：2015年06月12日

先修改1节点的

1.修改ocr中public的信息

[oracle@rac1 ~]$ oifcfg delif -global eth0
[oracle@rac1 ~]$ oifcfg setif -global eth0/172.168.1.0:public
[oracle@rac1 ~]$ oifcfg getif
eth0 172.168.1.0 global public
eth1 192.168.1.0 global cluster_interconnect

2. 停止1节点nodeapps资源

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

3.修改主机ip

[oracle@rac1 ~]$ oifcfg iflist
eth0  172.168.10.0
eth1  192.168.1.0
[root@rac1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

修改/etc/hosts文件中1节点的public ip和vip

[root@rac1 ~]# vi /etc/hosts
#public ip
192.168.0.10 --> 192.168.1.10
#vip
192.168.1.20 --> 192.168.1.20

[root@rac2 ~]# vi /etc/hosts
#public ip
192.168.0.10 --> 192.168.1.10
#vip
192.168.1.20 --> 192.168.1.20

重启网络服务

[root@rac1 ~]# service network restart
[oracle@rac1 ~]$ oifcfg iflist
eth0  172.168.1.0
eth1  192.168.1.0

4. 修改vip

[oracle@rac1 ~]$ su                                                                   
Password:                                                                             
[root@rac1 oracle]# srvctl modify nodeapps -n rac1 -A 172.168.1.20/255.255.255.0/eth0

5. 修改监听文件

$ vi $ORACLE_HOME/network/admin/listener.ora

6. 启动nodeapps资源

[oracle@rac1 ~]$ srvctl start nodeapps -n rac1

监听资源没有起来，可以看到其他资源均正常启动

[oracle@rac1 admin]$ crs_stat -t

7. 手动启动监听

[oracle@rac1 admin]$ lsnrctl start

8. 动态监听注册

[oracle@rac1 admin]$ sqlplus / as sysdba

9. 启动监听资源

[oracle@rac1 ~]$ crsctl start resources ora.rac2.LISTENER_RAC2.lsnr
Starting resources.
Successfully started CRS resources

10. 再次查看状态,已全部启动

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