摘要：

Unforeseen exception may exist in workflow system. It is very difficult to recover these exceptions for traditional workflow systems. A hierarchical exception recovery algorithm for transaction workflow is proposed. Recovery pattern, recovery strategy and other constraint conditions are introduced into workflow model. With the operation history log of workflow system, the algorithm can determine the end compensation point dynamically, so the compensation domain is confined and compensation costs are reduced.
