called an Oracle Local Registry (OLR）： each node in a cluster has a local registry for node-specific resources
Oracle Cluster 物理配置要求及限制
Oracle Clusterware 10g/11g 进程详解
在Cluster中的SQL节点上安装php-mysql会有冲突提示
测试一：模拟olr异常丢失的情况：
这里首先将olr renam
[root@vmrac2 cdata]# mv vmrac2.olr vmrac2.olr.bak
然后尝试去启动crs
[root@vmrac2 cdata]# crsctl start crs
CRS-4124: Oracle High Availability Services startup failed.
CRS-4000: Command Start failed, or completed with errors.
然后我们观察下 集群alert log的日志输出情况：
[grid@vmrac2 vmrac2]$ tailf alertvmrac2.log
