摘    要:近年来实时CORBA的在金融、电信、保险、医疗、制造业等行业发挥着越来越重要的作用,开发基于实时CORBA的应用程序,提高系统端对端的预测能力,使系统具有可靠健壮的性能.首先论述了实时CORBA体系结构与线程控制机制,对实时CORBA的ORB、POA与线程控制机制关系、实时CORBA线程的实现方式、线程的管理策略作了分析讨论,在这基础上讨论了建立实时系统的应用实例,将CORBA优先映射为本地优先,提供了灵活的线程管理机制,有效防止了线程的优先级翻转.

关 键 词:公共对象请求代理  对象请求代理  多线程  实时  优先级映射  CORBA  线程  研究  优先级翻转  管理机制  映射  应用程序  实时系统  分析  管理策略  关系  控制机制  体系结构  性能  预测能力  端对端  开发  作用  行业  制造业

Abstract:Real-time CORBA plays more and more important role in many fields such as finance, telecom, stock, medical treatment, industryetc. The application developed based on real-time CORBA, enhance the predict ability of end to end, and possess robust perfo rmance. First the real-time CORBA architectonic and thread control mechanism are discussed, the relations of ORB, POA of real-time CORBA related to thread mechanism, the multi threading implementation using real-time CORBA and thread manager policies are analyzed. Finally, ap-roject using multi threading of real-time CORBA is explained, mapping CORBA priority levels to native priority provide flexible thread management policy and limit effectively the priority reverse.
Keywords:CORBA  ORB  multi threading  real-time  priority mapping
