基于消息队列的工作流引擎及其容错设计

Workflow Engine Based on Message Queuing and Its Fault Tolerance Design

在流程定义工具、Web中间件和工作流引擎组成的分布式工作流平台上,以提高工作流引擎的可信性为目的,围绕软件容错设计、硬件和网络平台的可靠性、可靠消息传输模式,结合对实际生产的分析,提出一种新的可信构件设计方案。运行结果表明,该方案取得了较好的应用效果。

To improve the dependability of workflow engine in distributed workflow platform made up of workflow definition tool, Web middleware and workflow engine, this paper presents a new method of designing dependable component based on software fault tolerance, hardware and network platform reliability, and message transmission mode according to the system operation analysis. Practical application results show that this method is effective.
