地铁清分中心灾备系统设计

摘要

This paper classifies metro disaster-tolerant techniques of fare clearing center into two kinds according to different goals of backup, and designs an overall disaster-tolerant solution to application system, including core application system design, urban backup system design and data backup techniques. The article summarizes some ways for system operation engineers to handle different disasters by using the designed system to minimize business loss.%根据备份目标的不同,将地铁清分中心灾备系统分为两种类型.重点设计应用系统容灾的整体方案,包括主应用系统的设计、异地备份系统的设计和数据备份的技术；论述在各种灾难情况下,清分中心运营人员如何运用所设计的灾备系统使业务损失降到最低.
