profile通常指配置文件,crs_profile望文生义可知,就是管理集群的配置文件。在Oraclele RAC中,所有的CRS资源存放在OCR磁盘中,对于OCR更形象的比喻是类似于Windows的注册表。我们知道Windows注册表由类似树状的节点构成,其形式是KEY-VALUE,集群中的资源也是如此。Windows注册表可以整个导出,分支导出,也可以导入注册表信息。针对集群资源的管理crs_profile结合crs_register与crs_unregisterd等同于一个类似于Windows的regedit 管理工具。这么说就不陌生了吧,接着往下看。
一、crs_profile的帮助信息
对于Oracle clusterware大部分集群命令行工具而言,都提供丰富的操作指导。命令行下直接输入crs_profile将给出帮助信息
