2.2 Database Information
The CA MICS database is a repository of many types of
information. For CA MICS StorageMate, the data of most
interest includes RMF, SMF, VTOC, HSM, ASTEX, and catalog
data. All of these data sources are kept at the DETAIL
level, and also summarized at the DAYS, WEEKS, and MONTHS
levels. Each of these levels, or 'timespans' as they are
called in CA MICS, contains a different view of your data and
can be used to answer different questions about your resource
utilization. Because you may want to retain much of this
data for several days or months, each of the files in each of
the timespans may exist in a number of generations or cycles.
For example, if you decided to keep ten cycles of RMF data in
your DETAIL timespan, these cycles would be numbered from 1
to 10. Cycle 1 would contain the data from the most current
day, and Cycle 10 would contain data from ten days ago. The
next time you run CA MICS, the new data would be stored in
Cycle 1, existing Cycles 2-9 would bump up (or be 'aged') by
one number, and Cycle 10 would be deleted. This cycle
structure exists for every information area and in every
timespan. The number of cycles maintained for any given file
in any given timespan can vary, and is set by your CA MICS
System Administrator. A thorough understanding of the
structure and content of the database is central to the use
of CA MICS StorageMate.
Files used by CA MICS StorageMate include a minimum of one
cycle in the indicated timespan for each of the following
CA MICS product files:
DETAIL
Application Extension for ASTEX* - ASTADS
MVS Batch and Operations Analyzer - BATPGM, BATJOB, BAT_JS
DASD Space Analyzer - VCADAA, VCA_VS, VCAVOA
HSM Inventory Analyzer Option* - HSMMIG, HSMVOL, HSBBAC
DAYS
Application Extension for ASTEX* - ASTAVO
MVS Batch and Operations Analyzer - BATWDA
MVS Hardware and SCP Analyzer - HARDVA, SCPPGA
DASD Space Analyzer - VCADAA, VCA_VS
HSM Inventory Analyzer Option* - HSMMIG, HSBBAC
MONTHS
DASD Space Analyzer - VCADAA, VCA_VS, VCAVOA
HSM Inventory Analyzer Option* - HSMMIG, HSBBAC
* These files are only required if you want to use certain
reports distributed with the StorageMate product. If these
sources are not installed, you can still install and use
CA MICS StorageMate, but some reports and report options
will not be available.
Another important item of information you will need is the
list of valid CA MICS database Unit IDs for your installation
and a summary of the files and cycles contained in each.
Make a note of this and keep it handy for future reference.
You will need it to run the facilities within the CA MICS
StorageMate product.
The CA MICS database complex can be segmented into different
units to minimize operational problems, such as the
coordination of incoming transmissions from remote data
centers. Think of the complex as a partitioned data set
(PDS), with each individual informational unit being similar
to a member within the PDS. Files within these units might
equate to records within each PDS member. Each of these
unique units is identified in the CA MICS system by a one-
character identifier, known as a Unit database ID (Unit
DBID).
An example might be to have the following configuration of
CA MICS products and unit databases:
CA MICS Information Unit Data Center
Area Database Location
--------------------------------------------------
SMF, RMF, AST D Dallas
VCA, HSM V Dallas
SMF, RMF N New York
VCA, HSM, AST Y New York
These unit ID letters tell you where to find the data you
will need to run your inquiries. For example, to run a
report that requires only VCA data from the New York center,
use DBID Y. To run the same report for Dallas, specify DBID
V. To combine VCA data from both centers in the same report,
specify both Y and V.
