| Abstract: | The two stages scheduling algorithm analyzes the basic characteristics of the real-time transaction model based on func-tional alternatives and proposes a data structures to dynamically save the real information of the system.Then,several strategies,in-cluding choosing the best alternative,aborting an alternative and restarting a alternative,are present.The experimental results show that the algorithm can remarkably improve the successful ratios of the transactions and the reliability of the system. |
