Characterization of Java/sup TM/ application server workloads

This paper examines the workload characterization of a Java 2 Enterprise Edition (J2EE/sup TM/) application server workload. The application provides services for a mixture of e-commerce transactions continuously. This paper examines the variation of system observable behavior, program behavior and performance characteristics at the CPU level and their impact as a result of the variation of the payload of those different kinds of e-commerce transactions. Early results indicate that some methods could be useful in establishing the relationship between observable system configurations and program behavior. Furthermore, performance at the CPU level may be linked to these configurations. It may also help computer architects in collecting traces of workload that can cover a wide spectrum for performance simulation and analysis.
