摘    要:CORBA是一种当前流行的基于对象技术的中间件平台。它提供了一种松散的、异步的通信机制,解决分布式计算环境中不同硬件设备和软件系统的互联,增强了网络间软件的互操作性,解决传统分布式计算模式中的不足等问题。目前的CORBA产品大多缺乏容错机制,针对产品已有的缺陷和不足,给合了中间件技术的优点,运用对象复制技术和热备份技术实现容错服务。文章设计并实现了一种应用级容错CORBA系统,提高了系统的可靠性,满足了分布式系统对容错的要求。

关 键 词:中间件  CORBA  容错  复制

Abstract:Nowadays, the Common Object Request Broker Architecture (CORBA) is one of the most popular standard for middleware platforms based on object technology. It provides decoupted,asynochronous communication between suppliers and consumers, to solve problems such as interconnection among differenthardware equipment and software system in Distributed Computing Environment (DCE)o to strengthen operation of software among network. to resolve the deficiency m traditional DCEo most of the current CORBA products lack of fault tolerance issue, The face of product defects and deficiencies in the existing, To the combined advantages of middleware technology,Technology and the use of object replication to achieve fault-tolerant backup technology serviceso The article was designed and implemented an application-level fault-tolerant CORBA system,improve the reliability of the system, to meet the fault-tolerant distributed system requirements.
Keywords:Middleware  CORBA  Fault tolerance  Replication
