Maintenance
The maintenance price is adjusted as a result of an On/Off CoD activation.
Software
Software Parallel Sysplex license charge (PSLC) customers are billed at the MSU level that is
represented by the combined permanent and temporary capacity. All PSLC products are
billed at the peak MSUs enabled during the month, regardless of usage. Customers with WLC
licenses are billed by product at the highest four-hour rolling average for the month. In this
instance, temporary capacity does not necessarily increase the software bill until that
capacity is allocated to LPARs and actually consumed.
Results from the STSI instruction reflect the current permanent and temporary CPs. See
“Store system information instruction” on page 351 for more details.
8.5.6 IBM z/OS capacity provisioning
The z13s provisioning capability, combined with CPM functions in z/OS, provides a flexible,
automated process to control the activation of On/Off Capacity on Demand. The z/OS
provisioning environment is shown in Figure 8-14.

The z/OS WLM manages the workload by the goals and business importance on each z/OS
system. WLM metrics are available through existing interfaces, and are reported through IBM
Resource Measurement Facility™ (RMF) Monitor III, with one RMF gatherer for each z/OS
system.
