摘要
本文首先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在气田生产安全中的应用。通过本文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。
Through analysing how to improve reliability of the distributing multi-layer application system,the paper presents some kind of key techniques such as database connection pool,object pool,fault-tolerance model based on briefcase mechanism and dynamic load balance model based on negative feedback mechanism.It explains application of these techniques in production security with combination of DCOM /COM+ middleware and some cases.It provides an effective method for design and development of the high reliability system.
