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

The CRS consists of two cluster packages, voting disk and Oracle Cluster Registry, respectively. Voting disk, which is the voting disks, each node in the cluster periodically evaluates its own health, and then puts its status information on the voting disk. The nodes also view their running state and pass the informatio

Quickly deploy an Oracle RAC environment using an Oracle VM Template Oracle VM templates are pre-packaged and pre-configured virtual machines. In the communication between enterprise-level customers, I often use "simple, fast, and error-free" to deploy applications using Oracle
