摘要
工作流在某一点发生错误,导致工作流运行失败。通过调用失败路径上节点的补偿逻辑,以便将工作流恢复到先前的一个上下文环境。因为补偿节点是相当复杂和耗时的工作,减少工作流补偿节点的数量可大大提高工作流的补偿效率。基于工作流的数据和流程定义者所提供信息,文中提出了多种补偿范围,以便在不同条件下有效地减少补偿节点的数量。
Workflow at some point error occurred, resulting in workflow failure. By recovery the failure of nodes on the path of compensa- tion, workflow returns to a previous context environment. Beeause the compensation node is avery complex and time - consuming work, workflow to reduce the number of nodes compensation can greatly improve workflow efficiency of the compensation. Based on a detailed analysis Of dependencies history information and process designers to provide certain knowledge about workflow processes, presents a wide range of compensation, under different conditions in order to effectively reduce the amount of compensation nodes.
