OCR and voting Disk backups in Oracle RAC are described in my blog: oracle RAC Common maintenance tools and commands , and now take it separately to make a note, because OCR and voting disk Is too important for a RAC system.Oracle RAC Common maintenance tools and commandsHttp://blog.csdn.net/tianlesoftware/archive/2010/03/09/5358573.aspxa.

OCR is like a Windows registry that stores all configuration information related to the cluster and RAC database. It is also a public configuration, that is, multiple nodes share the same configuration information. Therefore, this configuration should be stored on the shared disk. This article mainly describes the OCR of the cluster and the amnesia caused by OCR
As a cluster, oraclecluster needs shared storage to store the configuration information of the entire cluster. ocr is the place where the configuration information is stored in use cases. The storage capacity of ocr is generally not too large.

Managing Oracle clusterware (OCR)Oracle Clusterware places the configuration information of the entire cluster on shared storage. The information includes the list of cluster nodes, the ing between cluster database instances and nodes, and the CRS Application resource information. The storage location is on the OCR Disk. in the entire cluster, only one Node can perform read and write operations on the

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

Tags: Oracle OCR Backup and RecoveryIntroduction to 1.OCR Disks The problem with forgetfulness is that each node has a copy of the configuration information and the configuration information of the modified node is not synchronized.

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,
