Oracle 10.2.0.4修改RAC的ip
Oracle 10.2.0.4修改RAC的ip
基本情况
数据库版本：Oracle 10.2.0.4
节点数：2
一． 停止oracle相关的所有进程, 包括数据库, asm, node application, crs本身.
1.1、关闭所有进程，crs_stop -all
2.2、 关闭crs后台进程, 在操作系统一级中止运行的crs后台进程, 必须在所有节点上运行.
[root@rac1 bin]# /etc/init.d/init.crs stop
Shutting down Oracle Cluster Ready Services (CRS):
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
Shutdown has begun. The daemons should exit soon.
[root@rac2 ~]# /etc/init.d/init.crs stop
Shutting down Oracle Cluster Ready Services (CRS):
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
Shutdown has begun. The daemons should exit soon.
1.3、验证进程是否全部关闭
[root@rac2 ~]# crs_stat -t
二、修改操作系统的ip设置
2.1、修改 /etc/hosts文件（所有的节点）
[root@rac1 ~]# vim /etc/hosts
127.0.0.1 rac1 localhost.localdomain localhost
172.20.225.91 rac1
172.20.225.92 rac2
10.73.5.91 rac1-priv
10.73.5.92 rac2-priv
172.20.225.81 rac1-vip
172.20.225.82 rac2-vip
[root@rac2 ~]# vim /etc/hosts
127.0.0.1 rac2 localhost.localdomain localhost
172.20.225.91 rac1
172.20.225.92 rac2
10.73.5.91 rac1-priv
10.73.5.92 rac2-priv
172.20.225.81 rac1-vip
172.20.225.82 rac2-vip
2.2、两个节点上分别修改eth0和eth1地址，重启使ip生效
三、修改存储链接
3.1 清除之前的链接（两个节点执行）
1）停止服务
service iscsi stop
2）去除挂载
iscsiadm -m node --op delete
3）重启服务
[root@rac1 ]# service iscsi restart
Stopping iSCSI daemon:
iscsid is stopped [ OK ]
Starting iSCSI daemon: [ OK ]
[ OK ]
Setting up iSCSI targets: iscsiadm: No records found!
[ OK ]
3.2重新链接
1）正确配置openfiler，请一定要严格按照文档，不要遗漏任何一步。
2）扫描
[root@100-201 ~]# iscsiadm -m discovery -t sendtargets -p 10.73.5.80
172.100.10.100:3260,1 iqn.2006-01.com.openfiler:LUN2
172.100.10.100:3260,1 iqn.2006-01.com.openfiler:LUN1
3）重启服务
service iscsi restart
四、启动crs，设置oracle中ip相关配置
3.1查看服务
[root@rac1 ~]# crs_stat -t
- Name Type Target State Host
- ------------------------------------------------------------
- ora.jscn.db application OFFLINE OFFLINE
- ora....n1.inst application OFFLINE OFFLINE
- ora....n2.inst application OFFLINE OFFLINE
- ora....SM1.asm application OFFLINE OFFLINE
- ora....C1.lsnr application OFFLINE OFFLINE
- ora.rac1.gsd application OFFLINE OFFLINE
- ora.rac1.ons application OFFLINE OFFLINE
- ora.rac1.vip application OFFLINE OFFLINE
- ora....SM2.asm application OFFLINE OFFLINE
- ora....C2.lsnr application OFFLINE OFFLINE
- ora.rac2.gsd application OFFLINE OFFLINE
- ora.rac2.ons application OFFLINE OFFLINE
- ora.rac2.vip application OFFLINE OFFLINE
[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.
3.3 使用oifcfg修改网卡设置, oifconfig可以用来设置和查看网卡使用的方式.
注： 如果修改的网段相同，可以不做这一步。
-- 查看当前配置：
[root@rac2 raw]# oifcfg getif -global
eth0 192.168.0.0 global public
eth1 10.10.10.0 global cluster_interconnect
-- 删除当前配置
[root@rac2 raw]# oifcfg delif -global eth0
[root@rac2 raw]# oifcfg delif -global eth1
[root@rac2 raw]# oifcfg getif
[root@rac2 raw]#
--查看当前网段
[root@rac1 ~]# oifcfg iflist
eth0 172.20.0.0
eth1 10.72.0.0
-- 重新添加
[root@rac2 raw]# oifcfg setif -global eth0/172.20.0.0:public
[root@rac2 raw]# oifcfg setif -global eth1/10.72.0.0:cluster_interconnect
[root@rac2 raw]# oifcfg getif
eth0 172.20.0.0 global public
eth1 10.72.0.0 global cluster_interconnect
[root@rac2 raw]# oifcfg iflist
eth0 172.20.0.0
eth1 10.72.0.0
注意： 这里IP 地址最一个为0. 代表的是一个网段。 修改的时候要切记。 否在在启动OCR 时 会报如下错误：
[ CRSOCR][4054413904] OCR context init failure. Error: PROC-44: 网络地址和网络接口操作中出错 网络地址和网络接口操作错误 [7]
