5.7.1 The CA MICS Root Directory

The CA MICS Root Directory is the name of the HFS
sub-directory to be used as the default location for storing
HFS files for the CA MICS Platform, CA MICS Data Integration
Applications, and CA MICS Management Applications.

In general, CA MICS HFS files are created in sub-directories
of the CA MICS Root Directory.  You may think of the CA MICS
Root Directory as the HFS corollary to the CA MICS
sharedprefix -- it becomes the "prefix" for common CA MICS
HFS files.

You should also note that CA MICS applications may give you
the option to override the CA MICS Root Directory in order to
secure HFS files for a specific application area as required
by your installation.  In essence, the HFS files are
equivalent to the MICF Production Reporting job stream
definition where you have the option to store job stream
definitions and report outputs in files that do not begin
with the CA MICS sharedprefix string.

While the CA MICS Root Directory is not required, certain
CA MICS features and products do require access to USS
facilities, definition of a CA MICS Root Directory, and
authorization to create HFS files.

For example, CA MICS Documentation Conversion and the CA MICS
Web Analyzer require access to USS services, HFS files, and
the CA MICS Root Directory.  If you choose not to take
advantage of these features and products, then you do not
need to define the CA MICS Root Directory.  However, it is
very likely that your installation is already running
applications using USS services and HFS files, and you will
presumably want to enable CA MICS to these system services.
