摘要: 在数据库管理系统中,DBMS资源的利用率对系统的影响是很大的。对基于反馈回路的自调优模型的基础上设计与实现DBMS资源自调优工具进行了研究。该工具能够根据资源利用情况,自动找到适合提高系统运行效率的DBMS资源配置参数。给出了实现该系统时用到的诊断树、资源关系模型和资源调整规划算法。

Abstract: In the design of DBMS,the high performance of DBMS is important.In this paper,a self-tuning model of dynamic-tinning of resource of DBMS was brought forward based on feedback model.This model can adjust system parameters automatically to achieve good performance.It also puts forward the dialog tree,model of relationship of resource,and the arithmetic used to make tinning plan.

Key words: resource of DBMS, dynamic-tunning, feedback model, self-tinning
