高可用性系统应用程序开发技术

THE DEVELOPING TECHNIQUE OF HIGH AVAILABILITY SYSTEM APPLICATION PROGRAM

本文研究了Ｃｌｉｅｎｔ／Ｓｅｒｖｅｒ 体系下网络计算模型， 总结了网络双机热备份应用软件的规律。高可用性技术的应用前景十分广泛，可应用于试验的数据采集、测试和控制等不允许数据丢失、任务中断的高可靠性计算应用领域 。

The article studies the network computing model of Client/Server,summarizes the rule of double servers hot standby of network . The application of the Hight Availability (HA) technique is very extensive .HA can be used in such high reliability computing application area, such as data collection,test and control ,which do not admit data lost and task interrupted.
