摘要： 容错是实现系统可靠性的一个重要手段。单一的容错策略已经不能满足当今分布式系统动态变化的要求,因此容错策略可配置的重要性就凸现出来。该文结合编译期反射和运行期反射,提出了可配置CORBA容错结构,并使用OpenC++和拦截器实现了一个容错CORBA原型系统。该方法不需要修改CORBA ORB,而只需要对应用作极少的改动。

Abstract: Fault tolerance is a main means of assurance of system reliability. Single fault tolerance policy can not satisfy the dynamic changes of nowaday distributed systems, so the configurability of fault tolerant policy becomes important. This paper presents the design and implementation of a configurable fault tolerant CORBA infrastructure that provides fault tolerance for CORBA applications by utilizing OpenC++ and interceptor. The approach does not require modification to the CORBA ORB, only requires minimal modifications to the application.
