The storage data of the 11gR2 RAC system is completely lost. The software of all nodes is installed on the local disk, and the local disk retains the OCR backup, the following describes how to restore the normal operation of Clusterwar
1. Oracle Cluster Registry (OCR)
OCR is used to solve the amnesia problem in the cluster,
The Cluster Environment configuration file is not stored in a centralized manner, but each node has a local copy. When the cluster runs normally, you can change the cluster configuration on any node, in addition, this change will be automatically synchronized to other nodes.
There is A special situation: node A is

Oracle Clusterware puts the entire cluster's configuration information on shared storage, which includes a list of cluster nodes, a cluster database instance to a node map, and CRS application resource information. It is also stored on an OCR disk (or OCFS file). Therefore, the importance of this configuration file is self-evident. Any action that makes an OCR configuration change is recommended to back up

However, if you have manually created a database (create database) and manually editedThe listener file is not recorded in OCR. This requires the Administrator to use the srvctl add command to manua
OCR is equivalent to the Windows registry. For Windows, all software information, users, configurations, and security are stored in the registry. In the same way, all cluster-related resources, configurations, nodes, and RAC databases are stored in this warehouse. If OCR is damaged, the cluster Service Startup exception occurs. You need to fix OCR. Therefore,
