1，分别在节点node1，node2 检查OLR的状态
[root@node1 ~]# ocrcheck -local
Status of Oracle Local Registry is as follows :
         Version                  :          3
         Total space (kbytes)     :     262120
         Used space (kbytes)      :       2652
         Available space (kbytes) :     259468
         ID                       : 231588647
         Device/File Name         : /g01/grid/app/11.2.0/grid/cdata/node1.olr
                                    Device/File integrity check succeeded

         Local registry integrity check succeeded

         Logical corruption check succeeded

[root@node2 ~]# ocrcheck -local
Status of Oracle Local Registry is as follows :
         Version                  :          3
         Total space (kbytes)     :     262120
         Used space (kbytes)      :       2652
         Available space (kbytes) :     259468
         ID                       : 1577698888
         Device/File Name         : /g01/grid/app/11.2.0/grid/cdata/node2.olr
                                    Device/File integrity check succeeded

         Local registry integrity check succeeded

         Logical corruption check succeeded

2，备份和恢复OLR

查看当前备份记录
[root@node1 ~]# ocrconfig -local -showbackup

node1     2014/06/11 10:42:30     /g01/grid/app/11.2.0/grid/cdata/node1/backup_20140611_104230.olr
[root@node1 ~]#

执行手工备份
[root@node1 ~]# date
Wed Jul 2 07:16:04 CST 2014

[root@node1 ~]# ocrconfig -local -manualbackup

node1     2014/07/02 07:13:06     /g01/grid/app/11.2.0/grid/cdata/node1/backup_20140702_071306.olr

node1     2014/06/11 10:42:30     /g01/grid/app/11.2.0/grid/cdata/node1/backup_20140611_104230.olr

3，在节点node1关闭clusterware
[root@node1 ~]# crsctl stop crs -f

4，恢复OCR，选择之前手工备份的20140702_071306版本
[root@node1 ~]# ocrconfig -local -restore \
> /g01/grid/app/11.2.0/grid/cdata/node1/backup_20140702_071306.olr

5，在节点node1重启启动clusterware
[root@node1 ~]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.

6，检测OLR
[grid@node1 ~]$ cluvfy comp olr

Verifying OLR integrity

Checking OLR integrity...

Checking OLR config file...

OLR config file check successful

OLR file check successful

WARNING:
This check does not verify the integrity of the OLR contents. Execute 'ocrcheck -local' as a privileged user to verify the contents of OLR.

OLR integrity check passed

Verification of OLR integrity was successful.

7，导出OLR
[root@node1 ~]# ocrconfig -local -export /home/grid/olr_export

[root@node1 ~]# ls -al /home/grid/olr_export
-rw------- 1 root root 94653 Jul 2 07:39 /home/grid/olr_export

导入OLR
[root@node1 ~]# ocrconfig -local -import /home/grid/olr_export
