三层分布式应用系统可靠性研究与实现

Research and implementation of reliability on three layer distributed application system

三层分布式应用系统是建立在网络上的,网络的不可靠性会影响系统的正常运行,这个问题常常没有引起系统开发者的重视,但后果往往是严重的。运用分布式应用服务器原理,分析了产生的原因,提出了解决的办法:通过事务服务实现状态可靠性,通过容错服务实现过程可靠性。

Three layer distributed application system runs on network, but no reliability of network brings a result that the system can not work. This problem is often ignored by developer of the system, but the aftereffect is severe. By use of application server principle, the cause is analysed and the way is brought that status reliability is realized by transaction service and process reliability is realized by tolerance failure service.
