1.3 Requirements

The CA MICS StorageMate product requires that the following
CA products are installed:

o CA MICS Platform
o CA MICS MVS Hardware and SCP Analyzer
o CA MICS MVS Batch and Operations Analyzer
o CA MICS DASD Space Collector
o CA MICS DASD Space Analyzer

The following products and options will extend the reporting
capabilities of the StorageMate product.  If these products
are not installed or implemented, some reports and report
options may not be available:

o CA MICS Application Extension for ASTEX
o HSM Inventory option for the CA MICS DASD Space Analyzer

Data Sources
------------
As illustrated in Figure 1-1, the CA MICS database contains
many information areas.  CA MICS StorageMate uses the VCA,
SCP, HAR, BAT, HSM, HSB, and AST information areas of the
CA MICS database.  Information from these areas is
integrated to give you a complete view of the storage
environment.

VTOC/CATALOG ACTIVITY (VCA) INFORMATION AREA

The VCA information area has files that are populated from
the CA MICS DASD Space Analyzer (VCA) and DASD Space
Collector (VCC).  VCC is usually run once a day on each
processing complex.  As the name suggests, it scans DASD
VTOCs and MVS system catalogs, extracting information about
data sets and volumes.  This information is analyzed and
summarized into a number of files.

HARDWARE (HAR) AND SYSTEM CONTROL PROGRAM (SCP) INFORMATION
AREAS

The HAR information area has files that are populated from
MVS RMF (Resource Measurement Facility) records via the
CA MICS Hardware and SCP Analyzer.  These raw records are
written by RMF at a user-specified interval.  Most
installations use intervals such as 15, 20, or 30 minutes as
the standard.  The information from this area reported by
CA MICS StorageMate includes device response times and I/O
rates.  CA MICS StorageMate also uses the SCP information
area in reporting.

BATCH (BAT) INFORMATION AREA

The Batch Information Area contains information populated
from MVS SMF (System Management Facility) records via the
CA MICS Batch and Operations Analyzer.  These records are
written when certain events occur, such as the end of a job
step.  Information from these files used by CA MICS
StorageMate includes device I/O activity by MVS workload and
information about work that was delayed due to storage-
related failures.

HSM MIGRATION (HSM) AND BACKUP (HSB) INFORMATION AREAS

These information areas contain information about user data
sets that are under control of DFHSM.  To use the HSM
information area, you must have implemented the HSM Inventory
option of the CA MICS DASD Space Analyzer.  This option
causes the DASD Space Collector to interface with DFHSM
during daily space collection, and collect and write records
containing information about data sets migrated or backed up
by DFHSM.  These records are then processed on a daily basis
by the analyzer and are used to create the files in the HSM
information areas.

ASTEX (AST) INFORMATION AREA

The ASTEX information area contains DASD and cache
performance data supplied by the CA Automated STorage EXpert
(ASTEX) product.  To use this data, you must have installed
the CA MICS Application Extension for ASTEX.  The data
provided in this information area contains very detailed
performance information collected at the data set, volume,
storage group, and control unit level.  ASTEX users should
review their ASTEX options carefully to make sure the
intervals and recording levels chosen for ASTEX reporting are
granular enough to provide adequate detail in this
information area.

TAPE DATA (EXTERNAL)

You can use an external interface to process data that
resides outside the CA MICS database.  This interface allows
you to extract information related to your automated tape
library, format that data set into a SAS database, and
include that database in CA MICS StorageMate reports.  While
this interface should work with most common tape management
products, samples are provided that are designed to support
the most commonly used tape library management products.  See
Appendix C for a further discussion of this facility.

TIMESPANS AND FILES

The chart below displays the files and timespans used by
CA MICS StorageMate in each information area.  Depending on
the options or defaults used when CA MICS was installed, some
of these files may not be active in the required timespans.
In this case, you will not be able to use some reports until
those files are activated.  Check with your CA MICS
Administrator to make sure all needed files are active in the
required timespans.
