1.1 Primary Areas of Application

The IMS Analyzer provides analysis and reporting capabilities
that aid in the management of complex IMS systems in the
following areas:

o  Performance Management - The ability to monitor resource-
   consuming subsystems is an important part of any
   performance tuning effort.  The IMS Analyzer provides
   statistical information on buffer pool usage,
   transactions, and IMS database statistics.   You can use
   this data to identify periods of IMS performance
   degradation so that you may take corrective action,
   resulting in significant system performance improvement.

o  Service Level Measurement - IMS information in the CA MICS
   database, combined with CA MICS' online reporting
   capabilities, provides a way to determine whether IMS-
   related performance objectives specified in service level
   agreements are being met or whether workload demands have
   increased past the levels at which performance objectives
   can be guaranteed.

o  Operational Issues - The IMS Analyzer can track and
   monitor changes to the IMS system configuration as well as
   the occurrence of specific system events to ensure that
   procedures are followed and that necessary resources are
   available.

o  Accounting and Chargeback - The IMS Analyzer data is
   suitable for basic billing of system resource use.  The
   data includes CPU resources, transaction counts, queue and
   message counts, database access counts, database I/O
   counts, and terminal message counts.  This information
   makes transaction accounting feasible.  Integration with
   CA MICS Accounting and Chargeback facilitates accounting
   for IMS usage for all or selected system resources.

o  Capacity Planning - The IMS Analyzer maintains a database
   of historical usage and performance data.  This
   facilitates growth/trend projections at both the system
   and organizational unit (e.g., division or department)
   levels.

o  System Availability and Reliability - The IMS Analyzer
   provides information that can be used to monitor such
   measures as transaction ABENDs and IMS database closes.

o  Management Reporting - Users can group and summarize IMS
   information directly from the CA MICS database to create
   useful management reporting measures.  They can use
   standard reports that are distributed with the system, or
   they can easily create custom reports by using CA MICS'
   online facilities.  Additional tools allow resummarization
   when the summarized data in the database does not
   directly address reporting needs.
