手工导出OCR后台处理过程

OS:Red Hat Linux As 5
DB:10.2.0.5.6

  今天使用export手工备份ocr,执行如下命令的时候发现命令一直在执行,感觉是hang住了,按理说导出ocr是很快完成的,怎么感觉一直无法完成呢.
[root@node1 ocrbak]#/u01/app/oracle/product/10.2.0/crs_1/bin/ocrconfig -export /u01/app/oracle/ocr_export140210.bak
注意$ORACLE_HOME目下也有ocrconfig这个文件,正确是使用$ORA_CRS_HOME目录下的orcconfig文件．

一直等了很久还报了错误.
[root@node1 ocrbak]# /u01/app/oracle/product/10.2.0/crs_1/bin/ocrconfig -export /u01/app/oracle/ocr_export140210_06.bak
PROT-4: Failed to retrieve data from the cluster registry

下面查看日志,看到底导出的过程中oracle做了什么.

从以上日志发现,export过程中ocr在做upgrade操作,在整个过程中crs无法访问,从如下的命令可以看出：
node1-> crsctl check crs
CSS appears healthy
Cannot communicate with CRS
EVM appears healthy

node2-> crsctl check crs
CSS appears healthy
Cannot communicate with CRS
EVM appears healthy

奇怪的是客户端还是可以连接数据库的．
