One of the biggest challenges to the mainframes is very expensive “IBM Monthly License Charges (MLC)”. To run your mainframe on a reasonable, optimal and low MSU level, it is extremely important that you also optimize your WLM, capping settings, zIIP Utilization, PR/SM Weighting Factor and Logical CP Configuration.
Are your critical business workloads having trouble meeting SLOs during peak periods and during peak season? Are your online systems or your TSO too slow during peak periods? Does your batch workloads load your systems and causes high costs? Are your systems overloaded? Did your attempts to control MSU consumption fail? Do you know whether it’s critical business workloads or discretionary workloads driving high CPU Utilization?
Then you may have performance problems in your z/OS systems that require in-depth MSU MLC Optimization and Cost Reduction, Performance Analysis and Tuning
