A Transaction Model for Grid Computing

Feilong Tang, Minglu Li, Jian Cao

Abstract: In Grid environment, transaction must have the abilities to coordinate both short-lived operations and long-lived business activities, which can not directly be supported by traditional distributed transaction mechanisms. This paper introduces a transaction model based on agent technologies to satisfy these requirements. The model can coordinate both Atomic transaction and Compensation transaction. The agents shield users from complex transaction process. For two types of transactions, we respectively analyze the coordination mechanisms and provide corresponding algorithms. We also discuss the implementation of this model and propose a security solution.
