摘    要:传统的工作流管理系统事务处理能力不足,使得系统在失败时不能尽快恢复流程的执行。实现事务工作流原型系统,通过扩充建模功能,在建模阶段指定失败处理模式,当任务执行失败时,系统自动调用事务处理算法保证工作流事务的放松的原子性及数据的一致性和正确性,减少人工参与决策的工作。实验表明,引入了事务处理功能的工作流系统具有任务执行失败后快速恢复的能力。

关 键 词:工作流事务    恢复    原子性    失败处理模式    安全的保护点

Abstract:Traditional workflow management systems lack the abilities of handling transactions, thus cannot recover quickly enough. This paper introduced a prototype of transactional workflow by adding failure mode in modeling. When a task failed, the system could invoke the transactional algorithm with loosed atomicity to assure the data consistence, as well as decrease the work of participants. The experimental result shows that the workflow management system with transaction charactors can recover efficiently after failure.
