2.2.3 Performance Management Interface

Integrating the CA MICS database among all CA MICS products
allows you to use files from the CA MICS Batch and Operations
Analyzer as input to the CA MICS Performance Management
Product.  Examples of these interfaces are described below.

REAL STORAGE MANAGEMENT

The CA MICS Performance Management Product uses the Batch
User Program Activity File (BATPGM), System Task Program
Activity File (BAT_ST), and SMF User TSO Activity File
(BAT_TS) to allow you to manage real storage.  With
additional input from the CA MICS Hardware and SCP Analyzer,
you can use the Real Storage Management Analysis Reports to
track the allocation of real storage on a monthly, weekly,
daily, or hourly level.

Paging and swapping workloads are reported to allow analysis
of the relation between real storage allocation and the
operation of the page/swap subsystem.  Real storage
requirements at the performance group level are reported to
help you in evaluating the impact of new applications or
users, or the growth of existing applications.  Swapping
statistics are reported to assist you in investigating
swapping overhead.


I/O ANALYSIS REQUIREMENTS

The I/O Analysis inquiries, a product of the CA MICS
Performance Management Product, provide tape analysis
inquiries that allow you to analyze time periods that have
significant tape drive availability problems.  You can also
model the effects of moving existing work to different time
periods, adding additional tape demand, and tape drive
improvements.


BATCH INITIATOR SIMULATION

The Batch Initiator Simulation feature provided by the CA
MICS Performance Management Product allows you to evaluate
the effect of modifying the job class or initiator structure
for your workload.  It provides a simulator that evaluates
the initiator utilization and the input queue time of the
selected jobs under the proposed initiator structure.  It
then produces several reports.

The Initiator Busy Report displays the number of jobs
processed by each initiator and the percent of time that the
initiator was occupied.  If the initiator serves multiple
classes, figures are provided by class and for the entire
initiator.

The Job Queue Size Report provides queue statistics for each
reporting interval of the simulation.  The maximum queue
length, the queue length at the end of the interval, and the
number of arrivals is provided for each class.

The Job Input Queue Time Report consists of a plot for each
class.  Each plot presents a comparison of the actual and
simulated queue times for jobs in that class.

The Job Class Throughput Report presents a comparison of
actual and simulated throughput for reporting periods.
Average queue times are also provided, and all figures are
broken down by job class.

The interface between the two products supplies crucial
information for I/S performance management.
