CRS-4639: Could not contact Oracle High Availability Services

---

问题描述：
1 crs_stat  -t  报错：
CRS-4639: Could not contact Oracle High Availability Services


2 查看日志/opt/app/11.2.0/grid/log/rac2/crsd/crsd/log 发现error信息：
2012-12-21 00:50:29.706: [  CRSOCR][3046602448] OCR api procr_open_key failed for key SYSTEM.crs.11.2.0.1.0. OCR error code = 4 OCR error msg: PROC-4: The cluster registry key to be operated on does not exist.

由此可以看出是orc 集群配置信息出错！


解决办法：清除之前的配置信息，重新执行root.sh来配置

具体步骤：root 用户执行
1  /app/grid/grid11g/crs/install/rootcrs.pl -deconfig   
2  /app/grid/grid11g/root.sh

执行完查看：crs_stat -t   节点都正常
