1.1 CA MICS Structure and Terminology

A CA MICS complex can consist of up to 36 database units.
Each database unit consists of one or more Data Integration
Analyzers (DIAs). Each unit processes input measurement
records and outputs CA MICS information into the unit
databases. Unit databases may be "split" along information
areas, allowing separate data sets to be employed in the
unit.

CA MICS Data Integration Analyzers are referred to in this
guide as "components." These components, along with any
user-written components, provide resource-utilization
measurement data that is stored in files.

Files reside in one or more information areas. Files consist
of tables with rows and columns. Each item in a row or column
is a CA MICS data element, also known as a variable.

Each CA MICS data element is described in a data dictionary
that is in an appendix at the end of each data integration
guide.  Both MICF and Q&R provide access to these data
dictionaries (but they are not included in the PDFs and HTML
available on CA Support Online).

Your site's combination of CA MICS components is unique, but
most sites use the Hardware and SCP Analyzer component and
the Batch and Operations Analyzer component, both included
with the CA MICS base platform. The examples in this guide
focus on those components.

o The Hardware and SCP Analyzer component is focused on
  performance measurement data from IBM's RMF data source
  (SMF records 70 to 79). It is referenced by the
  three-character identifier RMF.

o The Batch and Operations Analyzer is the SMF component.
  Its primary focus is address space utilization data derived
  from a series of type 30 SMF records. These records
  describe who is using the environment and to what degree.
  Other operation data and software-product utilization
  (derived from SMF type 89 data) is also included in this
  component.
