14. Managing Physical Devices (continued) CFS is used in DBE/AC to provide the manageability of a file system in a large database environment. When used in DBE/AC with Oracle 9i RAC, Oracle accesses data files stored on CFS file systems via the ODM interface. This essentially bypasses the file system buffer cache and internal file system locking and allows asynchronous I/O. This means Oracle coordinates writing and locking of data. A single point of locking and buffering ensures maximum performance . Cluster Membership Services – VERITAS Cluster Server (VCS) is an open system clustering solution. It provides cluster membership services and high performance cluster interconnect software for RAC. The cluster membership services performs cluster integrity functions such as node monitoring in the RAC system and reconfigure the system automatically if a node failure is detected. The cluster interconnect provides the communication path for the cluster membership services and provides interprocess communication (IPC) for high-speed reliable communication between RAC processes. Oracle’s CacheFusion technology is an example of a RAC processes that utilize the high performance interconnect ..
