Aspect-oriented application-level scheduling for J2EE servers

Achieving sufficient execution performance is a challenging goal of software development. Unfortunately, violating performance requirements is often revealed at a late stage of the development. Fixing a performance problem at such a late stage is difficult in terms of cost and time. To solve this problem, this paper presents QoSWeaver, which provides aspect-oriented application-level scheduling. QoSWeaver weaves scheduling code written in an aspect into application code. The scheduling code gets an application thread to voluntarily yield its execution to implement a scheduling policy. The idea of scheduling at the application level is not new, but aspect-oriented programming makes it more realistic by separation of scheduling code. QoSWeaver also provides a profile-based pointcut generator, which automatically generates pointcuts for fine-grained scheduling. To investigate the ability of QoSWeaver for implementing practical scheduling policies, we used QoSWeaver for tuning the perform...
