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 based on Oracle 10g
