1. 手工备份GPNP profile和OCR

两节点分别：

su - grid
cd /oracle/app/grid/gpnp/*/profiles/peer
cp -p profile.xml profile.xml.bak.20160726

cd $ORACLE_HOME/gpnp/*/profiles/peer
cp -p profile.xml profile.xml.bak.20160726

任意节点：
as root:
/oracle/app/grid/bin/ocrconfig -manualbackup

/oracle/app/grid/bin/ocrconfig -showbackup manual

2. 停掉数据库
/oracle/app/grid/bin/srvctl stop database -d *

3. 修改之前状态
[grid@DB4 ~]$ oifcfg getif
bond0 200.31.43.0 global public
bond1 10.0.0.0 global cluster_interconnect

4. 修改
[grid@DB4 ~]$ oifcfg setif -global bond1/10.10.63.4:cluster_interconnect

5. 修改后检查
[grid@DB4 ~]$ oifcfg getif
bond0 200.31.43.0 global public
bond1 10.0.0.0 global cluster_interconnect
bond1 10.10.63.4 global cluster_interconnect

6. 停掉CRS
/oracle/app/grid/bin/crsctl stop crs
/oracle/app/grid/bin/crsctl disable crs

7. 操作系统层面进行私有IP修改
修改/etc/hosts
修改网卡IP

8. 启动CRS
/oracle/app/grid/bin/crsctl enable crs
/oracle/app/grid/bin/crsctl start crs

9. 删掉老的私网
oifcfg delif -global bond1/10.0.0.0

10. 删除后检查

[grid@DB4 ~]$ oifcfg getif
bond0 200.31.43.0 global public
bond1 10.10.63.4 global cluster_interconnect

11. 启动数据库

[root@DB4 grid]# /oracle/app/grid/bin/srvctl start database -d *

12. 最后检查集群资源状态
[root@DB4 grid]# /oracle/app/grid/bin/crsctl status res -t
