哈哈，刚说最后一篇，闲的无聊又搞了个测试。
环境：
OS:redhat 5.8
DB:Oracle 10.2.0.5 raw device
我们要养成经常备份ocr跟votedisk的习惯。但是ocr跟votedisk没有备份也是可以重建的。就像控制文件。但是过程较为麻烦。以下为详细步骤：
首先备份ocr跟votedisk：
[[email protected] ~]#
[[email protected] ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 2
Total space (kbytes) : 1048296
Used space (kbytes) : 3292
Available space (kbytes) : 1045004
ID : 1891074113
Device/File Name : /dev/raw/raw1
Device/File integrity check succeeded
Device/File Name : /dev/raw/raw2
Device/File integrity check succeeded
Cluster registry integrity check succeeded
[[email protected] ~]# crsctl qeury css votedisk

[[email protected] ~]# crsctl query css votedisk

[[email protected] ~]# ocrconfig -export /opt/ocr.bak
[[email protected] ~]# cd /opt/
[[email protected] opt]# ls
ocr.bak ORCLfmap votedisk.bak
删除配置:
[[email protected] install]# ./rootdelete.sh Shutting down Oracle Cluster Ready Services (CRS): Stopping resources. This could take several minutes. Error while stopping resources.
