FRWS: Towards failure resilient workflow system

Meta execution workflows allow modification of the workflow execution engine process to support design and run time changes. In this paper, we present a framework to execute workflows in a seamless manner by handling exceptions and failures, and thereby ensuring consistency in the process of execution. We built a framework using meta execution engine where the workflow execution engine and other components of WFMS are workflows. Our system allows specification, instantiation, modification and execution of workflows on-the-fly with less human intervention even when failures occur. We also provide design and implementation aspects of our FRWS system and demonstrate its applicability for different failure scenarios of a buyer-seller e-contract.
