在做操作之前需要手工備份OCR，這樣即使修改失敗，也能還原回來

對IP 地址做如下修改：

192.168.72.30 rac1 -----&gt192.168.72.70

192.168.72.40 rac2 -----&gt192.168.72.80

192.168.72.31 rac1-vip ------&gt192.168.72.71

192.168.72.41 rac2-vip ------&gt192.168.72.81

10.10.10.30 rac1-priv ------&gt11.11.11.70

10.10.10.40 rac2-priv -------&gt11.11.11.80

一．停止oracle相關的所有程式, 包括資料庫, asm, node application, crs本身.

1.1 檢視當前系統上crs執行的狀態

[root@rac1 oracle]# 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

1.2 關閉資料庫

　　[root@raw1 bin]# ./srvctl stop database -d raw

1.3 關閉asm例項

[root@rac1 oracle]# srvctl stop asm -n rac1

[root@rac1 oracle]# srvctl stop asm -n rac2

1.4 關閉其他應用程式

[root@rac1 oracle]# srvctl stop nodeapps -n rac1

[root@rac1 oracle]# srvctl stop nodeapps -n rac2

1.5 關閉crs後臺程式, 在作業系統一級中止執行的crs後臺程式, 必須在所有節點上執行.

一節點：

[root@rac1 oracle]# /etc/init.d/init.crs stop

Shutting down Oracle Cluster Ready Services (CRS):

Sep 22 11:14:22.759 | INF | daemon shutting down

Stopping resources. This could take several minutes.

Successfully stopped CRS resources.

Stopping CSSD.

Shutting down CSS daemon.

Shutdown request successfully issued.

Shutdown has begun. The daemons should exit soon.

二節點：

[root@rac2 oracle]# /etc/init.d/init.crs stop

Shutting down Oracle Cluster Ready Services (CRS):

Sep 22 11:15:00.995 | INF | daemon shutting down

Stopping resources. This could take several minutes.

Successfully stopped CRS resources.

Stopping CSSD.

Shutting down CSS daemon.

Shutdown request successfully issued.

Shutdown has begun. The daemons should exit soon.

二修改作業系統的ip設定

2.1 修改 /etc/hosts 檔案。保持2個節點的一致

[root@rac1 oracle]# cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

192.168.72.70 rac1

192.168.72.80 rac2

192.168.72.71 rac1-vip

192.168.72.81 rac2-vip

11.11.11.70 rac1-priv

11.11.11.80 rac2-priv

2.2 在兩個節點上分別修改eth0和eth1地址：

一節點eth0：

[root@rac1 oracle]# more /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

BROADCAST=192.168.72.255

HWADDR=00:0C:29:C8:3D:94

IPADDR=192.168.72.70

NETMASK=255.255.255.0

NETWORK=192.168.72.0

ONBOOT=yes

TYPE=Ethernet

USERCTL=no

IPV6INIT=no

PEERDNS=yes

二節點eth0：

[root@rac2 oracle]# more /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

BROADCAST=192.168.72.255

HWADDR=00:0c:29:37:d0:3a

IPADDR=192.168.72.80

NETMASK=255.255.255.0

NETWORK=192.168.72.0

ONBOOT=yes

TYPE=Ethernet

USERCTL=no

IPV6INIT=no

PEERDNS=yes

一節點eth1：

[root@rac1 oracle]# more /etc/sysconfig/network-scripts/ifcfg-eth1

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]

DEVICE=eth1

ONBOOT=yes

BOOTPROTO=none

IPADDR=11.11.11.70

NETMASK=255.0.0.0

HWADDR=00:0C:29:C8:3D:9E

USERCTL=no

IPV6INIT=no

PEERDNS=yes

TYPE=Ethernet

二節點eth1：

[root@rac2 oracle]# more /etc/sysconfig/network-scripts/ifcfg-eth1

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]

DEVICE=eth1

ONBOOT=yes

BOOTPROTO=none

IPADDR=11.11.11.80

NETMASK=255.0.0.0

HWADDR=00:0c:29:37:d0:44

TYPE=Ethernet

USERCTL=no

IPV6INIT=no

PEERDNS=yes

2.3 在兩個節點上分別重啟網路服務，使修改的IP生效。

[root@rac1 ~]# service network restart

[root@rac2 ~]# service network restart

三．啟動crs, 設定oracle中ip地址相關的設定.

　　3.1 在兩個節點啟動crs, 並關閉隨crs啟動的應用程式

[root@rac1 ~]# /etc/init.d/init.crs start

Startup will be queued to init within 30 seconds.

[root@rac2 ~]# /etc/init.d/init.crs start

Startup will be queued to init within 30 seconds.

由於oracle所有應用設定為自動啟動, 所以在crs啟動時會試圖啟動所有的服務, 但是在對oracle相關的ip地址進行設定時需要crs處於執行狀態. 但是資料庫, asm和node application處於停止狀態, 在一個節點執行以下命令：

[root@rac1 admin]# ./srvctl stop database -d orcl

[root@rac1 admin]# srvctl stop asm -n rac1

[root@rac1 admin]# srvctl stop asm -n rac2

[root@rac1 admin]# srvctl stop nodeapps -n rac1

[root@rac1 admin]# srvctl stop nodeapps -n rac2

[root@rac1 admin]# crs_stat -t

Name Type Target State Host

------------------------------------------------------------

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 使用oifcfg修改網路卡設定, oifconfig可以用來設定和檢視網路卡使用的方式.

注：如果修改的網段相同，可以不做這一步。

-- 檢視當前配置：

[root@rac1 oracle]# oifcfg getif -global

eth0 192.168.72.0 global public

eth1 10.0.0.0 global cluster_interconnect

-- 刪除當前配置

[root@rac1 oracle]# oifcfg delif -global eth0

[root@rac1 oracle]# oifcfg delif -global eth1

[root@rac1 oracle]# oifcfg getif

-- 重新新增

[root@rac1 oracle]# oifcfg setif -global eth0/192.168.72.0:public

[root@rac1 oracle]# oifcfg setif -global eth1/11.11.11.0:cluster_interconnect

[root@rac1 oracle]# oifcfg getif

eth0 10.85.10.0 global public

eth1 192.168.1.0 global cluster_interconnect

[root@rac1 oracle]# oifcfg iflist

eth0 192.168.72.0

eth1 11.0.0.0

注意：這裡IP 地址最一個為0. 代表的是一個網段。修改的時候要切記。否在在啟動OCR 時會報如下錯誤：

[ CRSOCR][4054413904] OCR context init failure. Error: PROC-44: 網路地址和網路介面操作中出錯網路地址和網路介面操作錯誤 [7]

3.3 修改VIP

[root@rac1 oracle]# srvctl modify nodeapps -n rac1 -A 192.168.72.71/255.255.255.0/eth0

[root@rac1 oracle]# srvctl modify nodeapps -n rac2 -A 192.168.72.81/255.255.255.0/eth0

3.4 設定listener.ora和tnsnames.ora, 檢查這些檔案中是否有指定原來ip的地方, 修改為更改後的ip地址。

[root@rac1 admin]# more listener.ora

# listener.ora.rac1 Network Configuration File: /oracle/app/product/10.2.0/db_1/network/admi

n/listener.ora.rac1

# Generated by Oracle configuration tools.

LISTENER_RAC1 =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521)(IP = FIRST))

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.72.70)(PORT = 1521)(IP = FIRST))

)

SID_LIST_LISTENER_RAC1 =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /oracle/app/product/10.2.0/db_1)

(PROGRAM = extproc)

)

注意：如果你使用了ocfs，修改ocfs配置檔案(/etc/ocfs/cluster.conf),驗證修改後是否可用。

3.5 啟動node applications, asm, 資料庫

[root@rac1 admin]# srvctl start nodeapps -n rac1

[root@rac1 admin]# srvctl start asm -n rac1

[root@rac1 admin]# srvctl start nodeapps -n rac2

[root@rac1 admin]# srvctl start asm -n rac2

[root@rac1 admin]# 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....C2.lsnr application ONLINE ONLINE rac2

ora.rac2.ons application ONLINE ONLINE rac2

3.6 確認IP, 修改完成。
