2. USAGE GUIDELINES


The Space Analyzer creates and maintains a database of
detailed and summary information about:

    - data sets existing on primary storage
    - catalog entries for VSAM data sets on primary storage
    - all DASD volumes
    - data sets archived to DFHSM migration levels 1 and 2
    - backup versions of data sets on primary storage
    - DASD volumes with daily DFHSM volume-level statistics
    - tapes under the control of DFHSM

The following sections describe some usage considerations and
guidelines for the data maintained by the CA MICS Space
Analyzer.  Some of the material here is summarized from more
detailed discussions in later chapters and thus may appear to
be repetitive.  Our intent is to survey the "bigger picture"
of usage in this chapter leaving certain details to other
chapters.  For example, while we present some file usage
guidelines here in Chapter 2, we explain file usage in depth
in Chapter 5, including diagrams of file structure and a data
elements list.

This section contains the following topics:

2.1 Methods of Using the Data

2.2 Management Support Applications

2.3 Miscellaneous Usage Notes for All Files
