23 The Oracle Clusterware Voting Disk and Oracle Cluster Registry The Oracle Clusterware requires the following two critical files: Voting Disk Manages cluster membership by way of a health check and arbitrates cluster ownership among the instances in case of network failures. RAC uses the voting disk to determine which instances are members of a cluster. The voting disk must reside on shared disk. For high availability, Oracle recommends that you have multiple voting disks. The Oracle Clusterware enables multiple voting disks but you must have an odd number of voting disks, such as three, five, and so on. If you define a single voting disk, then you should use external mirroring to provide redundancy. Oracle Cluster Registry (OCR) Maintains cluster configuration information as well as configuration information about any cluster database within the cluster. The OCR also manages information about processes that the Oracle Clusterware controls. The OCR stores configuration information in a series of key-value pairs within a directory tree structure. The OCR must reside on shared disk that is accessible by all of the nodes in your cluster. The Oracle Clusterware can multiplex the OCR and Oracle recommends that you use this feature to ensure cluster high availability. You can replace a failed OCR online, and you can update the OCR through supported APIs such as Enterprise Manager, the Server Control Utility (SRVCTL), or the Database Configuration Assistant (DBCA). Note: Both the voting disks and the OCRs must reside on either cluster file system files or on shared raw devices that you configure before you install the Oracle Clusterware and RAC.
