摘    要:事务处理是网格计算能否投入实际应用尤其是商业应用的关键技术之一,用于网格环境下的事务处理必须同时提供协调短时操作和长时间的商业活动的能力,基于Gtobus Toolkit和代理技术,提出了一种能够同时管理原子事务和聚合事务的事务协调机制,研究了相应的可以容错各种失败的协调算法,通过自动产生和执行补偿事务,聚合事务协调机制可以满足网格计算中对长事务的处理要求。

关 键 词:网格  原子事务  聚合事务  补偿事务

Abstract:Transaction is one of the key technologies that decide whether grid computing may be applied to actual applications, especially to commercial applications. The transaction for grid environment must provide the abilities to coordinate both short-lived operations and long-lived business activities. Based on the Globus Toolkit and agent technology, a transaction mechanism is proposed which can simultaneously manage atomic transaction and cohesion transaction, and the corresponding coordination algorithms which enable transaction to recover from various failures are also studied. By generating and executing compensation transaction automatically, the cohesion transaction mechanism may satisfy the requirements of long-lived transaction in grid computing.
Keywords:grid  atomic transaction  cohesion transaction  compensation transaction
