测试Oracle 11g Cluster 中OLR的重要性

背景：

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

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：
