修改10G RAC public IP && VIP

一、场景：因服务器的网络变更，所有ip地址需要重新分配，oracle RAC下的ip地址就需要做相关的修改，这里需要对public ip地址及VIP地址做修改，至于心跳ip地址，还是延续使用原先的ip地址；
二、IP地址:
1、原先ip地址分配
node1==>
[oracle@trsen01 ~]$ more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
10.1.198.151 trsen01
10.1.198.152 trsen02
192.168.10.151 trsen01-priv
192.168.10.152 trsen02-priv
10.1.198.153 trsen01-vip
10.1.198.154 trsen02-vip
node2===>
[oracle@trsen02 ~]$ more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
10.1.198.151 trsen01
10.1.198.152 trsen02
192.168.10.151 trsen01-priv
192.168.10.152 trsen02-priv
10.1.198.153 trsen01-vip
10.1.198.154 trsen02-vip
2、现有IP地址分配
node1===>
[oracle@trsen01 ~]$ more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.10.151 trsen01-priv
192.168.10.152 trsen02-priv
10.109.199.171 trsen01-vip
10.109.199.172 trsen02-vip
10.109.199.133 trsen01
10.109.199.134 trsen02
node2==>
[oracle@trsen02 ~]$ more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.10.151 trsen01-priv
192.168.10.152 trsen02-priv
10.109.199.171 trsen01-vip
10.109.199.172 trsen02-vip
10.109.199.133 trsen01
10.109.199.134 trsen02
三、注意事项：
1、注意网卡的mac地址与ip地址相对应(这里，我不确认，如果换了网卡是否可以，但是从crs的配置文件及mos文档里没有提到相关信息)；
2、在修改前后，应用最好可以切到临时库上或对数据做个可还原的备份；这里选择切至临时库，因为数据库较大，做个备份较慢；
四、相关知识点
oifcfg==>oracle接口配置工具
[oracle@trsen01 ~]$ 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 }
==>nodename:节点名;if_name:网卡接口名;subnet:网卡接口子网地址;
五、操作
=================================
public IP子网地址信息修改脚本
=================================
1、查看public ip地址及心跳地址的
[oracle@trsen01 ~]$ oifcfg getif
eth2 10.1.198.0 global public
eth3 192.168.10.0 global cluster_interconnect
[oracle@trsen02 ~]$ oifcfg getif
eth2 10.1.198.0 global public
eth3 192.168.10.0 global cluster_interconnect
这里子网地址信息变更
10.1.198.0==>10.109.199.0
变更命令如下
% $CRS_HOME/bin/oifcfg/oifcfg delif -global <if_name>[/<subnet>]
% $CRS_HOME/bin/oifcfg/oifcfg setif -global <if_name>/<subnet>:public
信息修改==>
$ORA_CRS_HOME/bin/oifcfg delif -global eth2/10.1.198.0
$ORA_CRS_HOME/bin/oifcfg setif -global eth2/10.109.199.0:public
===========================================
VIP 地址信息修改脚本
===========================================
1、查看VIP的配置信息
[oracle@trsen01 ~]$ srvctl config nodeapps -n trsen01 -a
VIP exists.: /trsen01-vip/10.1.198.153/255.255.255.0/eth2
[oracle@trsen02 ~]$ srvctl config nodeapps -n trsen02 -a
VIP exists.: /trsen02-vip/10.1.198.154/255.255.255.0/eth2
2、查看crs的状态
[oracle@trsen01 ~]$ crs_stat -t
Name Type Target State Host
------------------------------------------------------------
ora....SM1.asm application ONLINE ONLINE trsen01
ora....01.lsnr application ONLINE ONLINE trsen01
ora.gps01.gsd application ONLINE ONLINE trsen01
ora.gps01.ons application ONLINE ONLINE trsen01
ora.gps01.vip application ONLINE ONLINE trsen01
ora....SM2.asm application ONLINE ONLINE trsen02
ora....02.lsnr application ONLINE ONLINE trsen02
ora.gps02.gsd application ONLINE ONLINE trsen02
ora.gps02.ons application ONLINE ONLINE trsen02
ora.gps02.vip application ONLINE ONLINE trsen02
ora.gpsdb.db application ONLINE ONLINE trsen01
ora.....gps.cs application OFFLINE OFFLINE
ora....db1.srv application OFFLINE OFFLINE
ora....b1.inst application ONLINE ONLINE trsen01
ora....b2.inst application ONLINE ONLINE trsen02
3、停止数据库及ASM实例
$ srvctl stop instance -d <db_name> -i <inst_name> (对于 10.2.0.3 及以上版本，可以忽略)
$ srvctl stop asm -n <node_name> (对于 10.2.0.3 及以上版本，可以忽略)
$ srvctl stop nodeapps -n <node_name>
==>数据库实例及ASM实例及VIP资源的停止脚本
srvctl stop instance -d gpsdb -i trsendb1
srvctl stop instance -d gpsdb -i trsendb2
srvctl stop asm -n trsen01
srvctl stop asm -n trsen02
srvctl stop nodeapps -n trsen01
srvctl stop nodeapps -n trsen02
4、使用root用户修改 VIP 资源
这里10.1.198.153==>10.109.199.171
这里10.1.198.154==>10.109.199.172
# srvctl modify nodeapps -n <node> -A <new_vip_address or new_vip_hostname>/<netmask>/<[if1[if2...]]>
例如：
# srvctl modify nodeapps -n racnode1 -A racnode1-nvip/255.255.255.0/eth2
===>修改脚本
/opt/app/oracle/product/10.2.0/crs_1/bin/srvctl modify nodeapps -n trsen01 -A 10.109.199.171/255.255.255.0/eth2
/opt/app/oracle/product/10.2.0/crs_1/bin/srvctl modify nodeapps -n trsen02 -A 10.109.199.172/255.255.255.0/eth2
5、启动相关实例及资源
srvctl start instance -d trsendb -i trsendb1
srvctl start instance -d trsendb -i trsendb2
srvctl start asm -n trsen01
srvctl start asm -n trsen02
srvctl start nodeapps -n trsen01
srvctl start nodeapps -n trsen02
