備份：2臺主機：
私有網路配置不僅僅存在ocr中，還存在gpnp profile中，所以首先需要備份profile.xml：
[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 ~]#
[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
Ocr備份：
[root@host01 ~]# /u01/11.2.0/grid/bin/ocrconfig -manualbackup

情景一
*****************************
修改主機ip,vip,scan（網路卡名稱不變）
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
修改之後：
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.正常關庫、監聽和CRS
######/u01/11.2.0/grid/bin/crsctl stop crs
2.修改/etc/hosts配置檔案
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層修改公有網路卡地址
4.啟動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

[grid@host01 ~]$ oifcfg getif
eth4 10.168.0.0 global cluster_interconnect
eth3 172.16.0.0 global public
6.修改VIP--停止資料庫和監聽
srvctl stop vip -n host01
srvctl stop vip -n host02
#root使用者修改：
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

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
確認local_listener資訊:
檢查local_listener資訊，如果不正確需要修改，我這裡查詢是正確的。
--兩個節點分別確認：
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

IP地址 192.168.0.1
子網掩碼 255.255.255.0
AND運算(AND運演算法則：1 與1 = 1 ,1 與0 = 0 ,0 與1 = 0 ,0 與0 = 0 ,即當對應位均為1時結果為1，其餘為0。)
轉化為二進位制進行運算：
I P 地址 11000000.10101000.00000000.00000001
子網掩碼 11111111.11111111.11111111.00000000
AND運算
11000000.10101000.00000000.00000000
轉化為十進位制後為：
192.168.0.0 <==========該地址為oifcfg需要的地址。

eth3 100.16.0.0 global cluster_interconnect
eth4 192.168.0.0 global public
eth5 10.10.10.0 global cluster_interconnect
2，關閉crs
3，修改主機網路卡IP資訊
4，啟動crs
5，刪除多餘網路介面資訊
[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
附錄：
子網掩碼地址，在使用oifcfg 需要計算subnet。
Name:
oifcfg - Oracle Interface Configuration Tool.
Usage: oifcfg iflist [-p [-n]]
oifcfg setif {-node <nodename> | -global} {<if_name>/<subnet>:<if_type>}...
IP地址 192.168.0.1
子網掩碼 255.255.255.0
AND運算(AND運演算法則：1 與1 = 1 ,1 與0 = 0 ,0 與1 = 0 ,0 與0 = 0 ,即當對應位均為1時結果為1，其餘為0。)
轉化為二進位制進行運算：
I P 地址 11000000.10101000.00000000.00000001
子網掩碼 11111111.11111111.11111111.00000000
AND運算
11000000.10101000.00000000.00000000
轉化為十進位制後為：
192.168.0.0 <==========該地址為oifcfg需要的地址。
