This presentation is by Peter Enrico; one of the original WLM algorithm designers and developers. If your z/OS system working hard, or hardly working efficiently? In this session, we cut through the complexity of Workload Manager policy design and CPU optimization to give performance analysts a practical, actionable playbook. You'll learn how WLM service definitions directly influence CPU dispatching decisions, how to identify and eliminate CPU bottlenecks using RMF/SMF data, and how to tune goal mode policies to protect critical workloads without starving batch. Walk away with best practices you can apply the day you return to the office.
