Oracle10.2.0.4修改rac的ip

基本情况

数据库版本：oracle10.2.0.4

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
xxx.xxx.xxx.91 rac1
xxx.xxx.xxx.922 rac2
xx.xx.xx.91 rac1-priv
xx.xx.xx.92 rac2-priv
xxx.xxx.xxx.81 rac1-vip
xxx.xxx.xxx.82 rac2-vip
[root@rac2 ~]# vim /etc/hosts
127.0.0.1               rac2 localhost.localdomain localhost
xxx.xxx.xxx.91 rac1
xxx.xxx.xxx.922 rac2
xx.xx.xx.91 rac1-priv
xx.xx.xx.92 rac2-priv
xxx.xxx.xxx.81 rac1-vip
xxx.xxx.xxx.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

3.2 在两个节点启动crs, 并关闭随crs启动的应用程序

[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]

3.4 修改VIP
[root@rac2 raw]# srvctl modify nodeapps -n rac1 -A xxx.xxx.xxx.81/255.254.0.0/eth0
[root@rac2 raw]# srvctl modify nodeapps -n rac2 -A xxx.xxx.xxx.82/255.254.0.0/eth0

3.5 设置listener.ora和tnsnames.ora, 检查这些文件中是否有指定原来ip的地方, 修改为更改后的ip地址。
[root@rac2 ~]# vim /oracle/ora10g/product/db/network/admin/listener.ora

# listener.ora.rac1 Network Configuration File:
/u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora.rac1
# Generated by Oracle configuration tools.
LISTENER_RAC2 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip)(PORT = 1521)(IP = FIRST))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)(IP = FIRST))
    )
  )

SID_LIST_LISTENER_RAC2 =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /oracle/ora10g/product/db)
      (PROGRAM = extproc)
    )
  )


注意：如果你使用了ocfs，修改ocfs配置文件(/etc/ocfs/cluster.conf),验证修改后是否可用。

3.6 启动node applications, asm, 数据库
[root@rac1 bin]# srvctl start nodeapps -n rac1                              
[root@rac1 bin]# srvctl start nodeapps -n rac2
[root@rac1 bin]# srvctl start asm -n rac1
[root@rac1 bin]# srvctl start asm -n rac2
[root@rac1 bin]# srvctl start instance -d raw -i rac1
[root@rac1 bin]# srvctl start instance -d raw -i rac2

[root@rac2 ~]# crs_stat -t

Name           Type           Target    State     Host
------------------------------------------------------------
ora.jscn.db    application    ONLINE    ONLINE    rac2
ora....n1.inst application    ONLINE    ONLINE    rac1
ora....n2.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

五、修改“报主机不存在”

因为10.2.0.4RAC安装时候有bug，要指定LOCAL_LISTENER ，所以修改了ip以后，LOCAL_LISTENER 也要重新指定，

切记：这一步一定要做，不然远程不能登录
ALTER SYSTEM SET LOCAL_LISTENER = '(ADDRESS = (PROTOCOL = TCP)(HOST = xxx.xxx.xxx.81)(PORT = 1521))'  SID = 'jscn1';
ALTER SYSTEM SET LOCAL_LISTENER = '(ADDRESS = (PROTOCOL = TCP)(HOST = xxx.xxx.xxx.82)(PORT = 1521))'  SID = 'jscn2';
