    摘要: Workload type to be managed by a database management system (DBMS) is a key consideration in tuning the DBMS. Allocations for resources, such as main memory, can be very different depending on whether the workload type is Online Transaction Processing (OLTP) or Decision Support System (DSS). The DBMS also experiences changes in workload type during the normal processing cycle of the DBMS. It would be preferable for the database administrators to recognize the significant shifts of workload type that demand reconfiguring the DBMS to maintain acceptable levels of performance. Disclosed is a workload type classifier module, used by a DBMS, for recognizing workload types so that the DBMS may then manage or adjust its performance and reconfigure its resources accordingly. The classifier may be constructed based on the most significant workload characteristics that differentiate OLTP from DSS. The classifier is then used for identifying changes in workload types contained in a workload.

    摘要翻译: 由数据库管理系统(DBMS)管理的工作负载类型是调整DBMS的关键考虑因素。 根据工作负载类型是在线事务处理(OLTP)还是决策支持系统(DSS),资源分配(如主内存)可能会有很大的不同。 在DBMS的正常处理周期期间,DBMS还会遇到工作负载类型的变化。 数据库管理员最好认识到需要重新配置DBMS以保持可接受的性能水平的工作负载类型的重大变化。 公开了一种由DBMS使用的用于识别工作负载类型的工作负载类型分类器模块,以便DBMS可以随后管理或调整其性能并相应地重新配置其资源。 分类器可以基于区分OLTP与DSS的最重要的工作负载特征来构建。 然后,分类器用于识别工作负载中包含的工作负载类型的更改。
