中文摘要: 设计了一种在工作流子系统中,可根据工作流的异常类型自动选择容错策略的自适应容错模型,针对不可恢复异常采用了事务补偿机制的容错策略进行异常处理,而针对可恢复异常采用了自动恢复的容错策略进行异常处理。详细描述了该模型所采用的消息队列、事务补偿机制、自动恢复机制。
Abstract:This paper designs a fault tolerance model, according to the type of fault, automatically selecting fault tolerance strategy in workflow subsystem. To unrecoverable exception, transaction compensation mechanism is used for exception handling. To recoverable exception, automatic recovery strategy is used for exception handling. Detailed description of the message queue, transaction compensation mechanism, automatic recovery mechanism which are used in the model are presented.
