1、主机名：
#Public Network - (eth0)
192.168.10.11 rac1
192.168.10.12 rac2
#Private Interconnect - (eth1)
10.10.10.11 rac1priv
10.10.10.12 rac2priv
#Public Virtual IP (VIP) addresses - (eth0)
192.168.10.21 rac1vip
192.168.10.22 rac2vip
2、生成listener的cap文件,用于重建ocr后注册监听(也可以用后面的netca)
crs_stat -p ora.rac1.LISTENER_RAC1.lsnr > /oracle/backup/ora.rac1.LISTENER_RAC1.lsnr.cap
crs_stat -p ora.rac2.LISTENER_RAC2.lsnr > /oracle/backup/ora.rac2.LISTENER_RAC2.lsnr.cap
3、停掉所有的资源,备份ocr、votingdisk并重新格式化
crs_stop -all
crsctl stop crs
备份OCR：
[root@rac1 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :

Total space (kbytes) : 104216

Cluster registry integrity check succeeded
ocrconfig -export /oracle/backup/ocr_20100531.bak
[root@rac1 ~]# ocrconfig -export /oracle/backup/ocr_20100531.bak
备份votedisk:
[root@rac1 ~]# crsctl query css votedisk
0. 0 /dev/raw/raw2
located 1 votedisk(s).
破坏OCR，Voting磁盘
在两边用root执行：
/oracle/app/crs/install/rootdelete.sh
/oracle/app/crs/install/rootdeinstall.sh
[root@rac1 ~]# dd if=/dev/raw/raw2 f=/oracle/backup/votedisk_20100531.bak

在每个节点依次执行(root 用户)：
如果是10.2.0.1 版本，在最后一个节点上执行的时候会因为静默vipca的bug抛出异常，在该节点上图形化
界面调用VIPCA。
