Abstract(in English) Under wireless environment, a transaction often aborted due to the unexpected communication disconnection. At each abortion, a user needs to reconnect to the system and to start the transaction over again. To address this problem we investigate the transaction system that resumes the aborted process when the user reconnects to the system. In this paper, we propose the Mobile Envionment Transaction Intermediate System (METIS). To raise concurrency, METIS releases a lock while waiting for the user to reconnect. This is realized with tentative commit and compensative transaction. The tentative commit terminates the transaction process temporarily. We implemented METIS and confirmed that it successfully resumes the transaction after the sudden disconnection with less than 7% of overhead.
