| 摘 要： | 面向修复计算把硬件故障、软件错误和操作员失误当作不可避免的事实，研究的是面对事实的处理技术。它着眼于通过降低MTTR而提高系统的可用性，同时减少系统的总拥有成本。本文介绍了可修复计算采用的技术，详细论述了集群系统高可用性所采用的方法和技术。

| Abstract: | Recovery-Oriented Computing (ROC) takes the perspective that hardware faults, software bugs, and operator errors are facts to avoid coped with, not problems to avoid. By concentrating on Mean Time to Repair (MTTR) rather than Mean Time to Failure (MTTF), ROC reduces recovery time and thus offers higher availability. Since a large portion of system administration is dealing with failures, ROC may also reduce total cost of ownership. In addition to giving some techniques of ROC, we show three techniques and methods of higher availability in cluster system. |
