摘要
针对复杂应用领域工作流的特点 ,提出了一种确保工作流并发执行正确性的方法·首先定义任务冲突 ,冲突类别 ,同名共享锁和同名互斥锁的概念 ,而后给出了一种基于这些概念扩展的工作流并发控制机制·在这种并发调度机制中 ,由于充分考虑了不同工作流执行的并发控制 ,同一工作流不同实例之间执行的并发控制等工作流并发特点 ,使该并发机制能够确保复杂应用环境中多工作流多实例并发执行的正确性·
An approach was proposed to ensure the concurrent executing correctness of workflows for the workflow features of complicated applications. The task conflict, conflict class, shared locking and exclusive locking of the same task name were defined. A workflow concurrency control mechanism was proposed based on these concepts. Considering workflow concurrent executing features, such as the concurrent execution of different instances of intra workflow as well as inter workflow, the mechanism ensures the concurrent executing correctness of instances of intra workflow and inter workflow.
