三峡工程管理系统高可用性设计与应用

Design and Application of High Availability of Three Gorges Project Management System

三峡工程管理系统(TGPMS)是为三峡工程建设管理而设计的大型集成化工程管理系统。通过简要介绍系统高可用性的设计与实施方法,并回顾TGPMS系统数据库架构变迁所经历的三个阶段,总结了现有系统在高可用性设计方面的不足之处,就发展趋势进行了展望。

Three Gorges Project Management System（TGPMS） is designed for the construction and management of Three Gorges Project.It is an integrated and large-scaled project management system.The design and implementation of high availability of TGPMS database is introduced and three phases of the evolution of system architecture is reviewed herein.The deficiencies and development of high-availability of existing system is also prospected.
