如果此命令执行有问题，会在$CRS_HOME/log/rac1/client目录下产生文件，文件名ocrdump_.log。如果命令执行出现问题，可以从这个日志查看问题原因。
2.ocrcheck
如果OCR内容一致，产生如下输出：
[oracle@rac1 ~]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 2
Total space (kbytes) : 104344
Used space (kbytes) : 3808
Available space (kbytes) : 100536
ID : 503754514
Device/File Name : /dev/raw/raw1
Device/File integrity check succeeded
Device/File not configured
Cluster registry integrity check succeeded
如果OCR内容不一致，输出中会出现以下提示：
Device/File needs to be synvhronixed with the other device
执行这个命令过程中，会在$CRS_HOME/log//client目录下产生ocrcheck_.log日志文件。

查看ocr的自动备份（ocr的备份由master节点完成，默认四小时一次，如果在某个节点上看到的备份为几个月前的，则该节点不是当前的master节点)：
[oracle@rac1 client]$ ocrconfig -showbackup
使用导出导入进行OCR的备份和恢复：
在对集群做调整前，如：增删节点等操作前，应该对OCR进行一次备份，可以使用export备份到指定文件。如果做了replace或restore等操作，Oracle建议使用”cluvfy comp ocr -n all”命令做一次全面检查。
(1)关闭所有节点的CRS
节点1：
[root@rac1 crsd]# crsctl stop crs
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
节点2：
[root@rac2 ~]# crsctl stop crs
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
（2）导出OCR的内容。
[root@rac1 crsd]# cd
[root@rac1 ~]# ocrconfig -export ocrexp.exp
（3）启动CRS
节点一：
[root@rac1 ~]# crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly
节点二：
[root@rac2 ~]# crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly
[root@rac2 ~]# crs_stat -t
