Abstract: This paper proposes a process integrity control algorithm for migrating workflow, it is based on the research of migrating workflow network and executing mode of task block. The algorithm realizes integrity of task block combining with local recovery and migrating recovery, guarantees the executive integrity of migrating workflow process by deriving migrating instances mechanism. Example illustrates that the algorithm can produce effective control of migrating workflow process.

Key words: migrating workflow, migrating instance, process integrity

摘要： 在研究基于任务片的迁移工作流网络和执行模式的基础上，提出迁移工作流过程完整性控制算法。该算法采用本地恢复和迁移恢复相结合实现任务片的完整性，通过迁移实例派生机制保证整个迁移工作流过程的执行完整性。实例证明该算法可以实现迁移工作流过程完整性的有效控制。
