2.10.2 Usage Guidelines

Subcapacity pricing is IBM's charging methodology for
certain software based on the utilization capacity of the
LPARs in which the products run.  This pricing method offers
LPAR-based pricing for subcapacity eligible software
products, based on the highest four-hour rolling average
utilization of the LPARs where the product ran.  There are
many advantages and disadvantages to moving to a subcapacity
pricing method, so careful planning and analysis is
important. You will need to understand the prerequisites for
subcapacity pricing, create a software inventory, create a
capacity and growth plan, and determine your current capacity
and your system usage in contrast to your product usage
across all LPARs in which a product ran.

The CA MICS Performance Manager, IBM License Manager (ILM)
Analysis queries, and the CA MICS Capacity Planner can
determine your current capacity and usage for each LPAR and
help you develop a capacity plan for the future. See the CA
MICS Capacity Planner guide for more information on capacity
planning for z/OS.

The Product Measured Usage queries can help you analyze
product resource consumption, create a software inventory,
and report the combined system usage in contrast to the
combined product usage across all LPARs.

The following sections present guidelines to consider when
using the available queries to report on product measured
usage.

    1 - LPAR Product Resource Consumption
    2 - Combined Hourly System Usage by Product
