Abstract: Due to the autonomy and dynamic migration of mobile agent, the poepe r integrates transactional technology, exactly-once property and message queue i n mobile agent system .And the paper proposes the stage concept , using observ er s to monitor the progress of an agent's execution and recover from failures , and additionally reduced the blocking probability of agent. Last the paper pres ents a high available fault-tolerant mechanism of mobile agent.
