测试oracle 11g cluster 中OLR的重要性

called an Oracle Local Registry (OLR）： each node in a cluster has a local registry for node-specific resources

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
