1.检查olr 的状态:
[root@vmrac1 ~]# ocrcheck -local
Status of Oracle Local Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 2748
Available space (kbytes) : 259372
ID : 935756415
Device/File Name : /u02/app/11.2.0.3/grid/cdata/vmrac1.olr
Device/File integrity check succeeded
Local registry integrity check succeeded
Logical corruption check succeeded
2.将olr的内容转储到txt 文档,可查看olr的内容:
# ocrdump -local -stdout
3.导出/导入 olr 的内容:
--- 导出 OLR
# ocrconfig –local –export file_name
/*file_name 为导入文件,导出的文件名,这个文件名是自定的 eg:olr_myhost1_20090603_0130_export */
--- 导入 OLR:
# ocrconfig –local –import file_name
/*file_name 为导入文件,导出的文件名,这个文件名是自定的 eg:olr_myhost1_20090603_0130_export */
note:
》 Oracle recommends that you use the -manualbackup and -restorecommands and not the -importand -exportcommands.
》 When exporting OLR, Oracle recommends including "olr", the host name, and the timestamp in the name string.
For example:olr_myhost1_20090603_0130_export
4.手动备份OLR:
# ocrconfig –local –manualbackup
olr 会在grid 安装完成后,或者升级后备份一次。之后就不会自动备份 。oracle 建议在对 ocr 存储迁移后对OLR 进行手动备份一次。
**OLR缺省备份目录:Grid_home/cdata/host_name.
----修改OLR 备份目录:
ocrconfig -local -backuploc new_olr_backup_path
----查看olr 备份文件内容:
ocrdump -local -backupfile olr_backup_file_name

这里需要注意下 olr:ocrconfig -manualbackup 和 ocrconfig -local -restore 是配套使用的,ocrconfig -local -export 和 ocrconfig -local -import 是配套使用的,也就是说 ocrconfig -local -export file_name 导出的文件不用用作 ocrconfig -local -restore 使用
5.还原OLR:
To restore OLR:
----停crs
# crsctl stop crs
----恢复OLR:
# ocrconfig -local -restore file_name /*file_name为olr的备份路径中的文件名,可以通过 ocrconfig -local -showbackup 来查看*/
-----确认olr 的状态(检查olr 内容的逻辑完整性):
# ocrcheck -local
----重启crs
# crsctl start crs
----使用cvu验证olr 在集群中的完整性(注意:不检查olr 内容的逻辑完整性)
$ cluvfy comp olr
grid@vmrac1 ~]$ cluvfy comp olr
