在线事务处理系统性能评测框架研究

Study on performance evaluation framework oriented to online transaction processing system

在线事务处理(online transaction processing,OLTP)系统在不同的应用环境下存在着模型的差异,但是作为典型的数据库应用系统,其在不同应用下的性能评测又存在着一定的共性。针对用户自身应用领域的性能评测环境,提出了一种针对OLTP系统进行性能评测的通用框架,用户可以动态配置数据规模、事务混合比例等测试参数。在框架基础上,以银行中间业务这一典型的OLTP应用为例,实现了面向银行中间业务的OLTP性能评测系统,通过实验验证了评测系统及所提框架的有效性。

As a typical database application system,although OLTP（online transaction processing） systems have different operation models in different application environments,there are still some common features,especially in the performance evaluation field.In order to establish an OLTP-oriented performance evaluation environment being adaptable to different application requirements,a performance evaluation framework dedicated to OLTP system is proposed,in which testers can easily customize the database model and configure the transaction model dynamically.Based on this evaluation framework,an OLTP-oriented bank inter-mediary business test system is presented to illustrate the test flow and to verify the effectiveness of this evaluation framework.
