Whole-Stack Analysis and Optimization of Commercial Workloads on Server Systems

The evolution of the Web as an enabling tool for e-business introduces a challenge to understanding the execution behavior of large-scale middleware systems, such as J2EE [2], and their commercial workloads. This paper presents a brief description of the whole-stack analysis and optimization system – being developed at IBM Research – for commercial workloads on Websphere Application Server (WAS) [5] – IBM’s implementation of J2EE – running on IBM’s pSeries [4] and zSeries [3] server systems.
