摘　　要：自适应数据库负载控制是一个性能优化过程,用来提高数据库系统的整体性能。分析了自适应数据库负载控制的研究现状,提出了基于替换策略的负载控制方法,该方法通过竞争决策算法和替换策略对负载进行优化过滤来提高数据库系统的性能。仿真实验表明,该方法可以有效提高客户的满意率和系统实现价值,并且可以增强系统的稳定性。Workload control in autonomic database is a process of performance optimization, which is used to improve the whole performance of database systems. This paper analyzed the research status of workload control in autonomic database and proposed a control method based on replacement strategy, this method carried on the optimization filter through the competitive decision algorithm and replacement strategy to improve the database system performance. The simulation experiments show that this method can improve the customer’s satisfaction rate and the system’s realization value effectively, it can also improve the system’s stability.
