# ./oifcfg delif–global
添加接口配置，需要切換到root用戶
# ./oifcfg setif -global eth0/192.168.1.119:public
# ./oifcfg setif -global eth1/10.85.10.119:cluster_interconnect
RAC 修改IP 這個操作本身也只有幾步操作， 但是它涉及到OCR。 所以要格外小心。一般來說，如果不是必須要修改的話，儘量不要去修改OCR 的東西。 穩定第一。 在做之前，要手動的OCR 進行一個備份， 這樣即使修改失敗，也能還原回來。 OCR的備份。另外，Public/Private對應的的主機名不能更改，如果確實需要更改主機名，需要重新安裝CRS。
實驗對IP 地址做如下修改：
Public IP 10.85.10.119/121 -- > 10.85.10.219/221
Privite IP 192.168.1.119/121 -- > 192.168.1.219/221
Virtual IP 10.85.10.122/123 -- > 10.85.10.222/223
修改 /etc/hosts 文件。 保持2個節點的一致
# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
10.85.10.219 raw1
10.85.10.221 raw2
192.168.1.219 raw1-priv
192.168.1.221 raw2-priv
10.85.10.222 raw1-vip
10.85.10.223 raw2-vip
在兩個節點上分別修改eth0和eth1地址：
raw1
# more /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
IPADDR=10.85.10.219
NETMASK=255.255.255.0
ONBOOT=yes
GATEWAY=10.85.10.253
# more /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
IPADDR=10.85.10.221
NETMASK=255.255.255.0
ONBOOT=yes
GATEWAY=10.85.10.253
raw2
# more /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=static
IPADDR=192.168.1.219
NETMASK=255.255.255.0
ONBOOT=yes
GATEWAY=192.168.1.1
# more /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=static
IPADDR=192.168.1.221
NETMASK=255.255.255.0
ONBOOT=yes
GATEWAY=192.168.1.1
在兩個節點上分別重啓網絡服務，是修改的IP生效。
raw1,raw2
# service network restart
啓動crs, 設置oracle中ip地址相關的設置.
在兩個節點啓動crs, 並關閉隨crs啓動的應用程序
# /etc/init.d/init.crs start
Startup will be queued to init within 90 seconds.
# /etc/init.d/init.crs start
Startup will be queued to init within 90 seconds.
由於oracle所有應用設置爲自動啓動, 所以在crs啓動時會試圖啓動所有的服務, 但是在對oracle相關的ip地址進行設置時需要crs處於運行狀態. 但是數據庫, asm和node application處於停止狀態, 在一個節點執行以下命令：
# ./srvctl stop database -d raw
# ./srvctl stop asm -n raw1
# ./srvctl stop asm -n raw2
# ./srvctl stop nodeapps -n raw1
# ./srvctl stop nodeapps -n raw2
# ./crs_stat -t

使用oifcfg修改網卡設置, oifconfig可以用來設置和查看網卡使用的方式.如果修改的網段相同，可以不做這一步。該操作只在一個節點上進行即可
-- 查看當前配置：
# ./oifcfg getif -global
eth0 10.85.10.0 global public
eth1 192.168.1.0 global cluster_interconnect
刪除當前配置
# ./oifcfg delif -global eth0
# ./oifcfg delif -global eth1
# ./oifcfg getif
重新添加
# ./oifcfg setif -global eth0/10.85.10.0:public
# ./oifcfg setif -global eth1/192.168.1.0:cluster_interconnect
# ./oifcfg getif
eth0 10.85.10.0 global public
eth1 192.168.1.0 global cluster_interconnect
# ./oifcfg iflist
eth0 192.168.86.0
eth1 192.168.0.0
eth2 192.168.200.0
eth3 192.168.200.0
eth4 192.168.200.0
eth5 192.168.200.0
注意： 這裏IP 地址最一個爲0. 代表的是一個網段。 修改的時候要切記。 否在在啓動OCR 時 會報如下錯誤：
[ CRSOCR][4054413904] OCR context init failure. Error: PROC-44: 網絡地址和網絡接口操作中出錯 網絡地址和網絡接口操作錯誤 [7]
修改VIP
# ./srvctl modify nodeapps -n raw1 -A 10.85.10.222/255.255.255.0/eth0
# ./srvctl modify nodeapps -n raw2 -A 10.85.10.223/255.255.255.0/eth0
設置listener.ora和tnsnames.ora, 檢查這些文件中是否有指定原來ip的地方, 修改爲更改後的ip地址。
# vi /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
# listener.ora.raw1 Network Configuration File:
/u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora.raw1
# Generated by Oracle configuration tools.
LISTENER_RAW1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = raw1-vip)(PORT = 1521)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.85.10.219)(PORT = 1521)(IP = FIRST))
)
)
注意：如果你使用了ocfs，修改ocfs配置文件(/etc/ocfs/cluster.conf),驗證修改後是否可用。
啓動node applications, asm, 數據庫
# ./srvctl start nodeapps -n raw1
# ./srvctl start nodeapps -n raw2
# ./srvctl start asm -n raw1
# ./srvctl start asm -n raw2
# ./srvctl start instance -d raw -i raw1
# ./srvctl start instance -d raw -i raw2
# ./crs_stat -t
