Workload generator systems

Up to three IBM® System x® systems are used to generate the workload for the 64-bit and 31-bit WebSphere® study with J2EE workloads.

A WebSphere Application Server is present on the master workload generator, but not on the helper machines. These helpers only need a working Java™ Runtime Environment (JRE).

A workload generator consisting of multithreaded independent Java processes was also used. These processes run on all the clients, including the master client.

At workload submission rates greater than 500, two additional client systems are needed to create the workload.
