14.6.1.1 Control Parameters

Using a short set of menus that are described in Section 1.5
of this guide, you will arrive at the Workload Forecasting
Analysis screen shown in Figure 14-12.

Figure 14-12 shows the control parameters that were used to
generate the final Workload Forecasting Analysis model in
this case study.

 Figure 14-12.  Processor Usage Study Control Parameters

Note that in this case study the analyst previously generated
two resource element files.  The first, APU, contains a data
element, CPUADBTM, which represents the processor resource
usage time, adjusted to an IBM 9672-r95 system. This
adjustment was done to accommodate the fact that the LPAR
being analyzed has been moved over time to different hardware
platforms.  This file and data element are specified on the
control screen as the Primary CAP file and the Forecast
element respectively.  The second file, WLM, contains the
data elements that represent the processor resources consumed
by each of the workloads running on the system, and is used
to train the model.  This file is specified as the "Select
Elements from" file and the corresponding data elements are
specified on panel CAPG710.

The analyst also specified that the study would focus on
SYSID SYS1 and Zone 1, and will initially use 53 weeks of
planning data taken beginning in June of 2001.

For this study, we selected the Forecast report, in addition
to the normally produced reports and graphs for output. If
many observations are used in a given study, it might be
advantageous to exclude the Forecasting report to reduce the
volume of printed output.
