Abstract

Controlling Quality of Service (QoS) offered by application servers involves selecting appropriate configuration and parameter tuning that would match the application level load. This is a challenging problem, since application servers have many parameters at different levels that often influence the QoS in complex ways. This paper presents an empirical approach to keep the QoS offered close to the level specified by the hosted applications, using on-line configuration tuning. Based on this approach, an automated tuning system is currently under development to monitor and adapt the application server performance under variable load conditions.
