好久没更新了，今天来一发，就写下最近做的一个操作，修改11g RAC的public ip 以及 virtual ip，命令同样适用于10g。
ifconfig -a
lsattr -El en1
以上为AIX的命令
linux可以用以下命令查看：
ifconfig
more /etc/sysconfig/network-scripts/ifcfg-eth0
db1:[/]#ifconfig -a

注：因为11g的RAC使用ASM来存放OCR和Votingdisk , 所以要修改相关的配置信息，就不能停止ASM实例。
具体的CRS的后台进程可以通过如下命令查看：crsctl stat res -t -init
l 注意打开rfc1323参数 (=1)
no -a |fgrep rfc1323
lsattr -El en14
lsattr -El en9
no -o -prfc1323=1
--查看配置：
$ oifcfg getif -global
en5 10.10.10.0 global cluster_interconnect
en9 192.168.131.0 global public
en1 10.10.130.0 global cluster_interconnect
# oifcfg delif-global en9
$ oifcfg setif-global en9/192.168.130.0:public
--确认
$ oifcfg getif-global
# srvctlconfig nodeapps -a
--验证VIP的状态：
$ crsctl statres -t
--确保相关资源已经offline，如果没有，手工stop一下：
$ srvctl stopinstance -d DB -n db1
$ srvctl stopvip -n db1 -f
--用root用户修改VIP 信息
# ./srvctlmodify nodeapps -n db1 -A
192.168.130.14/255.255.255.0/en14
# ./srvctlmodify nodeapps -n db2 -A
192.168.130.15/255.255.255.0/en14
--验证
# srvctlconfig nodeapps -a
$ srvctlconfig scan
scan可不改，会自动修改。
若没有自动修改，可参照以下步骤手动修改：
--准备修改，关闭相关服务：
$srvctl stopscan_listener
$srvctl stopscan
$srvctl statusscan
--用root进行修改：
# ./srvctlmodify scan -n db-scan
--检查修改结果：
# srvctlconfig scan
注意：与修改private ip，vip 不一样，修改scan ip
无需停止数据库实例，asm或者重启crs，相对比较简单。
# crsctl stopcrs
在所有节点执行。
--启动crs
# crsctl startcrs
# srvctl startscan
# srvctl startscan_listener
# srvctl startcvu
# ./crs_stat-t

一.IP 信息
| 原IP地址 | 新IP地址 | 说明 |
| 192.168.131.11 | 192.168.130.11 | scan ip |
| 192.168.131.13 | 192.168.130.12 | public ip |
| 192.168.131.14 | 192.168.130.13 | public ip |
| 192.168.131.23 | 192.168.130.14 | virtual ip |
| 192.168.131.24 | 192.168.130.15 | virtual ip |
二. OS层面网络配置
2.1. 查看网卡设备信息
--aixifconfig -a
lsattr -El en1
以上为AIX的命令
linux可以用以下命令查看：
ifconfig
more /etc/sysconfig/network-scripts/ifcfg-eth0
db1:[/]#ifconfig -a
en1:flags=5e080863,18c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>

tcp_nodelay Enable/Disable TCP_NODELAYOption True
tcp_recvspace Set Socket Buffer Space forReceiving True
tcp_sendspace Set Socket Buffer Space forSending True
thread off Enable/Disable threadattribute True
2.2.修改/etc/hosts （两个节点修改）
$ vi /etc/hosts127.0.0.1 loopback localhost # loopback (lo0) name/address
::1 loopback localhost # IPv6 loopback (lo0) name/address
#PublicNetwork
-- en14
192.168.130.12 db1
192.168.130.13 db2
#PrivateInterconnect
10.10.131.130 db1-priv
10.10.131.136 db2-priv
#PublicVirtual IP (VIP) addresses
192.168.130.14 db1-vip
192.168.130.15 db2-vip
192.168.130.11 db-scan
三.修改GRID网络配置
3.1.启动CRS后台进程，仅保留crs的后台进程
先开启crs再关闭相关资源# ./crsctlstart crs
--停止相关资源：
# srvctl stopdatabase -d db
# srvctl stoplistener
# srvctl stopscan_listener
# srvctl stopscan
# srvctl stopcvu
# srvctl stopnodeapps -n db1
# srvctl stopnodeapps -n db2
--检查资源状态：
# crs_stat -t

注：因为11g的RAC使用ASM来存放OCR和Votingdisk , 所以要修改相关的配置信息，就不能停止ASM实例。
具体的CRS的后台进程可以通过如下命令查看：crsctl stat res -t -init
3.2.修改publicIP（只需在一个节点上操作即可）
按新情况在主机层面修改网络（AIX系统需要注意）l 注意打开rfc1323参数 (=1)
no -a |fgrep rfc1323
lsattr -El en14
lsattr -El en9
no -o -prfc1323=1
--查看配置：
$ oifcfg getif -global
en5 10.10.10.0 global cluster_interconnect
en9 192.168.131.0 global public
en1 10.10.130.0 global cluster_interconnect
# oifcfg delif-global en9
$ oifcfg setif-global en9/192.168.130.0:public
--确认
$ oifcfg getif-global
3.3.修改VIP（只需在一个节点上操作即可）
--查看VIP 信息# srvctlconfig nodeapps -a
--验证VIP的状态：
$ crsctl statres -t
--确保相关资源已经offline，如果没有，手工stop一下：
$ srvctl stopinstance -d DB -n db1
$ srvctl stopvip -n db1 -f
--用root用户修改VIP 信息
# ./srvctlmodify nodeapps -n db1 -A
192.168.130.14/255.255.255.0/en14
# ./srvctlmodify nodeapps -n db2 -A
192.168.130.15/255.255.255.0/en14
--验证
# srvctlconfig nodeapps -a
3.4.修改SCANIP（只需在一个节点上操作即可）
--查看scan状态：$ srvctlconfig scan
scan可不改，会自动修改。
若没有自动修改，可参照以下步骤手动修改：
--准备修改，关闭相关服务：
$srvctl stopscan_listener
$srvctl stopscan
$srvctl statusscan
--用root进行修改：
# ./srvctlmodify scan -n db-scan
--检查修改结果：
# srvctlconfig scan
注意：与修改private ip，vip 不一样，修改scan ip
无需停止数据库实例，asm或者重启crs，相对比较简单。
3.5.重启clusterware（所有节点root执行）
--停止crs# crsctl stopcrs
在所有节点执行。
--启动crs
# crsctl startcrs
3.6.检查所有进程的状态
# srvctl startlistener# srvctl startscan
# srvctl startscan_listener
# srvctl startcvu
# ./crs_stat-t
3.7.修改tnsnames.ora
vi $ORACLE_HOME/network/admin/tnsnames.ora参考文档：
