说明：资源对应的功能是CHM资源对应的功能是CHM.Cluster Health Monitor（以下简称CHM）是一个Oracle提供的工具，用来自动收集操作系统的资源（CPU、内存、SWAP、进程、I/O以及网络等）的使用情况。CHM会每秒收集一次数据。这些系统资源数据对于诊断集群系统的节点重启、Hang、实例驱逐(Eviction)、性能问题等是非常有帮助的。另外，用户可以使用CHM来及早发现一些系统负载高、内存异常等问题，从而避免产生更严重的问题。
由于 ora.crf服务生成的文件crf*.bdb,$HOSTNAME.ldb会很大，这样就对$GRID_HOME的使用率造成了压力。
根据上述描述可知ora.crf资源主要是用来收集信息的,而且在11.2.0.2之后才有,因此可以停止并禁用它
一、删除crf*.bdb和$HOSTNAME.ldb的步骤
