1、oracle11grac修改IP今天在一套RAC上修改了IP。包括pub,vip,scan5个IP。借鉴的文档如下：11GR2RACmodifyvip,publicip,privateip，scanvip实施步骤1修改目的根据业务的需求,需要由原来的临时IP改为生产ip,以下为调整前后对应的IP表调整前对应ip表主机名        类型       IP地址        网卡端口P570a   publicip  192.168.128.10 en0p570a-vipvip        192.168.128.12 en

2、0p570a-privprivateip172.168.128.10en2p570b   publicip   192.168.128.11en0p570b-vip vip      192.168.128.13 en0p570b-privprivateip 172.168.128.11en2scan-vipscan 192.168.128.100 en0调整后对应ip表主机名     类型      IP地址    网卡端口P570a publicip  10.76.31.112 en0p570a-vip  vip 10.7

3、6.31.113    en0p570a-priv privateip 192.76.31.113 en8p570b publicip 10.76.31.114  en0p570b-vip vip  10.76.31.115  en0p570b-priv privateip 192.76.31.115 en8scan-vip  scan   10.76.31.111 en0网卡端口可以用ifconfig-a显示出来2修改publicip,vip,scanvip2.1停止两边节点数据库，监听,并且停止crsgrid用户srvct

4、lstopdatabase-dgdcdc-oimmediatesrvctlstoplistener-np570asrvctlstoplistener-np570b第3页共11页root用户cd/grid/app/11.2.0/grid/bin./crsctlstopcrs可以用ps–ef

5、grepgrid看进程是否完全关闭2.2修改两边节点的/etc/hosts文件修改前先做个备份cp/etc/hosts/etc/hosts.bak修改后如下所示:10.76.31.112p570a10.76.31.113p570a-vip17

6、2.168.128.10p570a-priv10.76.31.114p570b10.76.31.115p570b-vip172.168.128.11p570b-priv10.76.31.111scan-vip注意这里私网ip地址暂时先不做修改，修改privateip时再修改2.3修改两个节点上的publicip,vip,scanvip2.3.1修改p570a节点publicip用smitty命令修改物理ipsmittytcpip选择en0修改ip为10.76.31.112，网关为10.76.31.1掩码为255.255.255

7、.02.3.2修改P570b节点publicip用smitty命令修改物理ipsmittytcpip选择en0第4页共11页修改ip为10.76.31.114，网关为10.76.31.1掩码为255.255.255.02.3.3两边节点启动crs,用oifcfg命令修改publicip一边节点做即可cd/grid/app/11.2.0/grid/bin./crsctlstartcrsroot用户先用oifcfggetif查看当前设置./oifcfggetifen0192.168.128.0globalpublicen2172.

8、168.128.0globalcluster_interconnect修改./oifcfgdelif-globalen0./oifcfgsetif-globalen0/10.76.31.0:public两边节点确认./oifcfggetifen010.76.31.0globalpublicen2172.168.128.0globalcluster_interconnect2.3.4修改VIP关闭databaseroot用户下运行以下命令cd/grid/app/11.2.0/grid/bin./srvctlstopdatabas

9、e-dgdcdc-oimmediate用srvctlconfigvip检查vip设置$srvctlconfigvip-np570aVIPexists.:p570aVIPexists.:/p570a-vip/192.168.128.12/255.255.255.0/eth0$s
