2.2.1 CA MICS Accounting and Chargeback

You can use CA MICS Accounting and Chargeback to apply a rate
per megabyte-hour against the space occupied by a data set or
group of data sets.  A comprehensive series of ISPF panels
guide the accounting administrator through the process of
assigning rates and other setup activities.

The result of this administrative setup is a series of SAS
macros that are strategically invoked by the CA MICS Space
Analyzer during the DAILY run.  No special pass of the data
is required to compute and store the cost; accounting is,
therefore, an optional but seamless extension to the
processing involved in updating the CA MICS database.

The CA MICS DASD components, VCA and HSM, offer a choice of
DETAIL or DAYS level accounting support.  DETAIL accounting
allows each individual data set to be priced according to the
space occupied over time.  DETAIL allows the customized
accounting algorithms access to the DSNAME and VOLSER
variables.  This could be particularly useful to any
enterprise that maintains different negotiated contracts for
service levels by end-users.  For example, customer x is
charged the standard rate for all data sets except for all
data sets beginning with "B753452.CICS.DATA*".  Standard
charges for these data sets are to be discounted by 75% per a
negotiated agreement.  Similar deals can be created for
dedicated VOLSER billing although that is not recommended
with the advent of system managed storage and the widespread
usage of DFHSM and other software which may move data to
different volumes.

DAYS level accounting presents summarized observations to
the CA MICS Accounting and Chargeback algorithms. Once
summarized into a single observation according to a set of
SORT/SEQUENCE variables, the DSNAME and VOLSER of a data set
are lost.  The aggregate of megabyte-hours for multiple data
sets under a given organizational entity is presented to the
accounting code.

Chapter 7 of this guide describes the parameters you must
specify for a proper implementation of accounting
applications. The CA MICS Accounting and Chargeback Guide
discusses various methodologies that can be used with CA MICS
files.
