2.4.1 Usage Guidelines

 
The IRD Implementation Planning Sample Application provides a
capacity planning database file with the database elements
you need for basic tracking, reporting, and forecasting of
processor resource usage at both the LPAR Cluster and LPAR
levels.
 
The information for this application is primarily derived
from either the DETAIL, DAYS, WEEKS, or MONTHS timespan of
the PR/SM LPAR Config/Activity (HARLPC) File.
 
The CPCMODID and CPUMOD elements, which identify the
processor type of the Central Processor Complex in use, are
obtained from the CA MICS CPU Activity (HARCPU) File.
 
Additional measurement metrics, such as Physical CPU
Adjustment Factor (CPUSUSEC), Service Units Available to MVS
Image (CPUSUAVL), and Accumulated Long-Term Average of CPU
MSUs (CPUTOLAC) are included as well.
 
In addition to providing basic information about processor
resource utilization, the IRD Implementation Planning Sample
Application provides measurement data concerning overall CPC
utilization and capacity that can be tracked and forecasted
as well.
