更改oracle RAC public ip,vip,scan ip和private ip
oifcfg - Oracle?接口配置工具
? 用法:? oifcfg iflist [-p [-n]]
??????? oifcfg setif {-node?| -global} {/:}...
??????? oifcfg getif [-node?| -global] [ -if?[/] [-type?] ]
??????? oifcfg delif [-node?| -global] [[/]]
??????? oifcfg [-help]
????????-?为通信网络所知的主机名
????????? -?系统中配置的接口的名称
?????????? -?接口的子网地址
????????? -?接口类型?{ cluster_interconnect | public | storage }
用例：
[email?protected]:/#oifcfg?getif -global
en0? 172.16.14.0? global? public
? ? ? ?en3? 1.1.14.0? global? cluster_interconnect
?
bash-2.03$ oifcfg iflist
ce0? 172.25.0.0
ce0? 172.25.198.0
ce1? 10.0.0.0
bash-2.03$ oifcfg iflist -p
ce0? 172.25.0.0? PRIVATE
ce0? 172.25.198.0? PRIVATE
ce1? 10.0.0.0? PRIVATE
bash-2.03$ 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
利用getif可以获取当前节点的配置：
bash-2.03$ oifcfg getif
ce0? 172.25.0.0? global? public
ce1? 10.0.0.0? global? cluster_interconnect
bash-2.03$ oifcfg getif -if ce0???????
ce0? 172.25.0.0? global? public
bash-2.03$ oifcfg getif -if ce1
ce1? 10.0.0.0? global? cluster_interconnect
利用oifcfg删除添加网络接口的时候，oracle用户的权限不够，需要切换为root用户执行：
bash-2.03# /data/oracle/product/10.2/crs/bin/oifcfg delif -global ce1
bash-2.03# /data/oracle/product/10.2/crs/bin/oifcfg setif -global ce1/10.0.0.0:cluster_interconnect
bash-2.03# /data/oracle/product/10.2/crs/bin/oifcfg getif -global??????????????????????????????????
ce0? 172.25.0.0? global? public
ce1? 10.0.0.0? global? cluster_interconnect

?? ??? ??? ??? ??? ?./srvctl start listener -n p570b
?? ??? ??? ??? ??? ?./srvctl start database –d gdcdc
?? ??? ?2.3.5 两边节点修改local_listener参数
?? ??? ??? ??? ??? ?该部分应该是在修改完VIP之后，重启数据库由oraagent自动注册进去。
?? ??? ??? ??? ??? ?Show parameter local_listener
?? ??? ??? ??? ??? ?NAME TYPE VALUE
?? ??? ??? ??? ??? ?------------------------------------ ----------- ------------------------------
?? ??? ??? ??? ??? ?local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD
?? ??? ??? ??? ??? ?DRESS=(PROTOCOL=TCP)(HOST=192.
