首先来看一下，使用到的命令
[root@node1 bin]# ./oifcfg -help
Name:
oifcfg - Oracle Interface Configuration Tool.
Usage: oifcfg iflist [-p [-n]]
oifcfg setif {-node <nodename> | -global} {<if_name>/<subnet>:<if_type>}...
oifcfg getif [-node <nodename> | -global] [ -if <if_name>[/<subnet>] [-type <if_type>] ]
oifcfg delif [-node <nodename> | -global] [<if_name>[/<subnet>]]
oifcfg [-help]
<nodename> - name of the host, as known to a communications network
<if_name> - name by which the interface is configured in the system
<subnet> - subnet address of the interface
<if_type> - type of the interface { cluster_interconnect | public | storage }
使用范例
查看网口信息
$ oifcfg iflist
ce0 172.25.0.0
ce0 172.25.198.0
ce1 10.0.0.0
查看私有网口信息
$ oifcfg iflist -p
ce0 172.25.0.0 PRIVATE
ce0 172.25.198.0 PRIVATE
ce1 10.0.0.0 PRIVATE
查看私有网口信息并显示掩码
$ oifcfg iflist -p -n
ce0 172.25.0.0 PRIVATE 255.255.0.0
ce0 172.25.198.0 PRIVATE 255.255.255.0
ce1 10.0.0.0 PRIVATE 255.255.255.0
查看当前节点的网口信息
$ oifcfg getif
eth0 192.168.0.0 global cluster_interconnect
eth1 192.168.2.0 global public
查看public类型的网卡
$ oifcfg getif -type public
eth1 192.168.2.0 global public
查看eth0的网卡信息
$ oifcfg getif -if eth0
eth0 192.168.0.0 global cluster_interconnect
查看node类型的配置信息，没有输出说明没有配置node类型
$ oifcfg getif -node czmmiao1
$ oifcfg getif -node czmmiao2
删除接口配置，需要切换到root用户
# ./oifcfg delif–global
添加接口配置，需要切换到root用户
# ./oifcfg setif -global eth0/192.168.1.119:public
# ./oifcfg setif -global eth1/10.85.10.119:cluster_interconnect
修改RAC ip实例
RAC 修改IP 这个操作本身也只有几步操作， 但是它涉及到OCR。 所以要格外小心。一般来说，如果不是必须要修改的话，尽量不要去修改OCR 的东西。 稳定第一。 在做之前，要手动的OCR 进行一个备份， 这样即使修改失败，也能还原回来。 OCR的备份。另外，Public/Private对应的的主机名不能更改，如果确实需要更改主机名，需要重新安装CRS。
实验对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个节点的一致
# 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
在两个节点上分别修改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
在两个节点上分别重启网络服务，是修改的IP生效。
raw1,raw2
# service network restart
启动crs, 设置oracle中ip地址相关的设置.
在两个节点启动crs, 并关闭随crs启动的应用程序
# /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.
由于oracle所有应用设置为自动启动, 所以在crs启动时会试图启动所有的服务, 但是在对oracle相关的ip地址进行设置时需要crs处于运行状态. 但是数据库, asm和node application处于停止状态, 在一个节点执行以下命令：
# ./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修改网卡设置, oifconfig可以用来设置和查看网卡使用的方式.如果修改的网段相同，可以不做这一步。该操作只在一个节点上进行即可
-- 查看当前配置：
# ./oifcfg getif -global
eth0 10.85.10.0 global public
eth1 192.168.1.0 global cluster_interconnect
删除当前配置
# ./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： 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]
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
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。
# 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),验证修改后是否可用。
启动node applications, asm, 数据库
# ./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
