摘要
针对当前网格工作流中任务具有不同的执行特点,提出了基于错误恢复属性的错误恢复方法。与传统的方法相比,该方法将工作流的活动划分了不同的错误恢复属性,根据不同的属性来选择相应的恢复策略,并对错误恢复策略进行仿真实验,对结果进行了分析。
Tasks have different performance characteristics in the current grid workflow,a new recovery method which based on the recovery property is presented.Compare to the old method,this method compartmentalizes the activity of the workflow process in to different failure recovery property,corresponding recovery strategy is selected according to the different property,and the results are analyzed through the simulation experiments.
