分布式计算环境可靠性关键技术在气田生产安全中的应用

APPLICATION OF RELIABILITY TECHNIQUE OF DISTRIBUTED COMPUTING ENVIRONMENT (DCE) TO THE PRODUCTION SECURITY IN THE GAS FIELD

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 analyzing how to improve the method of reliability based multi-tier distributed application system,this paper presents database connection pooling,object pooling,fault model base briefcase and negative feedback model based on dynamic load balancing, applies DCOM/COM+ middleware in the models,gives a project instance on the theory and at last provides an effective method for designing and development of high reliability application system.
