ocr,olr,gpnp profile:
备份：2台主机：
gpnp profile备份（所有节点）
私有网络配置存在olr中，还存在gpnp profile中，所以首先需要备份profile.xml(所有节点都需要备份)：
[grid@host01 peer]$ pwd
/u01/11.2.0/grid/gpnp/host01/profiles/peer
[grid@host01 peer]$ ls
pending.xml profile.old profile_orig.xml profile.xml
[grid@host01 peer]$ cp profile.xml profile.xml.bak

[root@host02 ~]# cd /u01/11.2.0/grid/gpnp/host02/profiles/peer/
[root@host02 peer]# ls
profile_orig.xml profile.xml
[root@host02 peer]# cp profile.xml profile.xml.bak

Olr备份：(2个节点都需要备份)

hosts配置文件备份：

cp /etc/hosts /tmp/hosts.bak0329

情景一

修改主机ip,vip,scan（网卡名称不变）
修改之前：

192.168.0.35 host01

192.168.0.36 host01-vip

192.168.0.38 host02

192.168.0.39 host02-vip

192.168.0.40 scan

修改之后：
172.16.0.135 host01
172.16.0.136 host01-vip
172.16.0.138 host02
172.16.0.139 host02-vip
172.16.0.140 scan

1.正常关库、监听和CRS

/u01/11.2.0/grid/bin/crsctl stop crs

2.修改/etc/hosts配置文件
172.16.0.135 host01
172.16.0.136 host01-vip
172.16.0.138 host02
172.16.0.139 host02-vip
172.16.0.140 scan
3.OS层修改公有网卡地址

4.启动crs

/u01/11.2.0/grid/bin/crsctl start crs

5.修改Public IP

[grid@host01 ~]$ oifcfg iflist
eth3 172.16.0.0
eth4 10.168.0.0
eth4 169.254.0.0

[grid@host01 ~]$ oifcfg getif
eth3 192.168.0.0 global public
eth4 10.168.0.0 global cluster_interconnect

[grid@host01 ~]$ oifcfg delif -global eth3
[grid@host01 ~]$ oifcfg setif -global eth3/172.16.0.0:public
[grid@host01 ~]$ oifcfg getif
eth4 10.168.0.0 global cluster_interconnect
eth3 172.16.0.0 global public

6.修改VIP--停止数据库和监听
srvctl stop vip -n host01
srvctl stop vip -n host02

root用户修改：

srvctl modify nodeapps -n host01 -A 172.16.0.136/255.255.255.0/eth3
srvctl modify nodeapps -n host02 -A 172.16.0.139/255.255.255.0/eth3

[root@host01 ~]# /u01/11.2.0/grid/bin/srvctl config vip -n host01
VIP exists: /172.16.0.136/172.16.0.136/172.16.0.0/255.255.255.0/eth3, hosting node host01
[root@host01 ~]# /u01/11.2.0/grid/bin/srvctl config vip -n host02
VIP exists: /host02-vip/172.16.0.139/172.16.0.0/255.255.255.0/eth3, hosting node host02
/u01/11.2.0/grid/bin/srvctl start vip -n host01
/u01/11.2.0/grid/bin/srvctl start vip -n host02

确认local_listener信息: //DB,ASM实例都需要确认。
检查local_listener信息，如果不正确需要修改，我这里查询是正确的。

--两个节点分别确认：
show parameter local_listener
--修改：
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=172.16.0.136)(PORT=1521))' sid='orcl1';
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=172.16.0.139)(PORT=1521))' sid='orcl2';

7.修改SCAN VIP

srvctl stop scan_listener
srvctl stop scan
srvctl status scan_listener
srvctl status scan

root

/u01/11.2.0/grid/bin/srvctl modify scan -n scan
/u01/11.2.0/grid/bin/srvctl config scan
SCAN name: scan, Network: 1/172.16.0.0/255.255.255.0/eth3
SCAN VIP name: scan1, IP: /scan/172.16.0.140

/u01/11.2.0/grid/bin/srvctl start scan
/u01/11.2.0/grid/bin/srvctl start scan_listener

情景二

eth4 10.168.0.0 global cluster_interconnect
eth3 192.168.0.0 global public
[grid@host01 ~]$

新的子网具有相同网卡的名称但不同的子网：

[grid@host01 ~]$ oifcfg setif -global eth4/100.16.0.0:cluster_interconnect
[grid@host01 ~]$ oifcfg getif
eth4 10.168.0.0 global cluster_interconnect
eth4 100.16.0.0 global cluster_interconnect
eth3 172.16.0.0 global public

2，关闭crs

srvctl modify nodeapps -n host02 -A 172.16.0.139/255.255.255.0/eth5

[root@host01 host01]# /u01/11.2.0/grid/bin/srvctl config vip -n host01
VIP exists: /172.16.0.136/172.16.0.136/172.16.0.0/255.255.255.0/eth5, hosting node host01
[root@host01 host01]# /u01/11.2.0/grid/bin/srvctl config vip -n host02
VIP exists: /host02-vip/172.16.0.139/172.16.0.0/255.255.255.0/eth5, hosting node host02

/u01/11.2.0/grid/bin/srvctl start vip -n host01
/u01/11.2.0/grid/bin/srvctl start vip -n host02

192.168.0.38 host02
192.168.0.39 host02-vip
192.168.0.40 scan

1,停止crs
2,修改hosts
3,修改主机ip地址到新网卡
4,启动crs
5,修改网卡信息

6,修改vip,scan地址

root用户修改：

srvctl stop vip -n host01
srvctl stop vip -n host02

root用户修改：

srvctl modify nodeapps -n host01 -A 192.168.0.36/255.255.255.0/eth4
srvctl modify nodeapps -n host02 -A 192.168.0.39/255.255.255.0/eth4

/u01/11.2.0/grid/bin/srvctl start vip -n host01

修改之后网络信息：《============eth5
10.10.10.123
10.10.10.124

1，修改网络接口信息
[grid@host01 ~]$ oifcfg setif -global eth5/10.10.10.0:cluster_interconnect
[grid@host01 ~]$ oifcfg getif
eth3 100.16.0.0 global cluster_interconnect
eth4 192.168.0.0 global public
eth5 10.10.10.0 global cluster_interconnect

2，关闭crs
3，修改主机网卡IP信息
4，启动crs
5，删除多余网络接口信息
[grid@host01 ~]$ oifcfg getif
eth3 100.16.0.0 global cluster_interconnect
eth4 192.168.0.0 global public
eth5 10.10.10.0 global cluster_interconnect
[grid@host01 ~]$ oifcfg delif -global eth3
[grid@host01 ~]$ oifcfg getif
eth4 192.168.0.0 global public
eth5 10.10.10.0 global cluster_interconnect

附录：

子网掩码地址，在使用oifcfg 需要计算subnet。
Name:

oifcfg - Oracle Interface Configuration Tool.

Usage: oifcfg iflist [-p [-n]]

oifcfg setif {-node <nodename> | -global} {<if_name>/<subnet>:<if_type>}...

subnet计算命令：
这是按照子网掩码252计算的网络配置，一会打算使用这个值模拟错误：
[root@lunar ~]# ipcalc -bnm 10.10.10.100 255.255.252.0
NETMASK=255.255.252.0
BROADCAST=10.10.11.255
NETWORK=10.10.8.0

IP地址　192.168.0.1
子网掩码　255.255.255.0
AND运算(AND运算法则：1 与1 = 1 ,1 与0 = 0 ,0 与1 = 0 ,0 与0 = 0 ,即当对应位均为1时结果为1，其余为0。)
转化为二进制进行运算：
I P 地址　11000000.10101000.00000000.00000001
子网掩码　11111111.11111111.11111111.00000000
AND运算
11000000.10101000.00000000.00000000
转化为十进制后为：
192.168.0.0 <==========该地址为oifcfg需要的地址。
