2.3.1 Usage Guidelines

 
The WLC Implementation Planning Sample Application provides a
capacity planning database file with the database elements
you need for basic tracking, reporting, and forecasting of
LPAR resource usage.
 
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 LPAR
resource utilization, the WLC Implementation Planning Sample
Application provides measurement data concerning overall CPC
utilization and capacity that can be tracked and forecasted
as well.
 
With the introduction of Defined Group Capacity users will
need the ability to summarize and forecast the MSU usage and
the MSU 4-hr rolling average within a given Defined Capacity
Group. The user can achieve this summarization by building a
WLC planning file using the data selection feature to process
only SYSIDs which belong to the Defined Capacity Group along
with the Composite SYSID feature to summarize the groups MSU
consumption and 4-hour rolling average.
 
Note: To accurately summarize a Capacity Group's MSU
      consumption and 4-hour rolling average all SYSID's
      belonging to the Capacity Group must be present within
      the input data.
