8.6.2 Data Types


During the MTI Dictionary load process (DICLOAD), each
resource subtype from the input data is scanned to determine
its data type.  This scanning process identifies a resource
subtype as a Minimum, Maximum, Accumulated, Rate (quantity
over time), Average, Percentage, or Unknown and saves this
information in the MTI Dictionary.  When the CA MICS
Component Generator is run, it uses this resource subtype
information to set the data type of the assigned CA MICS data
element.

Resource-subtypes with a data type of Accumulated, Minimum
and Maximum are considered the same as the CA MICS data
types.  Resource sub-types with a data type of Rate, Average
and Percent types are unique in that it is implied that some
formula must be used to derive the associated CA MICS data
elements.  In most cases, the elements required to compute
this value are not available and to simply assign a CA MICS
data type of retained or accumulated would not allow the
assigned CA MICS elements to be properly computed.  This can
result in severe inaccuracies in the data.

To facilitate recomputation of CA MICS data elements with a
data type of Rate, Average, and Percent data types the
CA MICS Component Generator performs the following special
actions:

o  CA MICS Component Generator will first create a root
   element.  A root element is an accumulated element that is
   used in the computation of a CA MICS element.

o  Next, the component generator will create the
   initialization code for the root element that will
   'de-compute' the CA MICS data element to obtain the
   original quantity.  For example, rate data elements are
   multiplied by DURATION.

o  Finally, the component generator internally generates code
   to perform the actual computation.

Whenever MTI cannot determine what type a particular
resource-subtype is, it is given a type of Unknown.
The CA MICS Component Generator will treat Unknown types
as Accumulated.

For Metrics load carried out through the use of the INPUTMTX
DD, the data type is taken verbatim from the data type found
in the record for the input data set specified on the
INPUTMTX DD.  This data set will be the latest Standardized
Metrics Update file.
