摘要
通过对提高分布式多层应用系统可靠性方法的分析,进而提出了数据库连接池、对象池、公文包机制容错模型和基于负反馈机制的动态负载平衡模型等几种可靠性关键技术,并结合DCOM/COM+中间件技术和具体实例说明了这些技术的应用。通过文中的研究为高可靠应用系统的设计与开发提供了一种行之有效的方法。
Analyzes how to improve the method of reliability based multi - tie distributed application system, Presents datable eormection pooling, object tx3oling, fault model and dynamic load balancing based on briefcase and negative feedback model, Applies DCOM/COM ＋ middleware in the models, and gives a project instance on the theory. At last provides an effective method for design and development of high reliability application system.
