5.7.2.3 HFS Space


The installation must provide space within the HFS to store
CA MICS files. This is called the CA MICS Root Directory.

Each CA MICS complex requires a unique CA MICS Root
Directory.  Do not attempt to share CA MICS Root Directories
between multiple CA MICS complexes (e.g., between a
production and test complex), as this action may result in
data corruption.

The name of the CA MICS Root Directory is specified on the
HFSROOT statement in sharedprefix.MICS.PARMS(JCLDEFC).

Note: The name of the root directory must be no longer than
64 characters. If it is, DOC2HTML will abend.

By default, HFSROOT has a value of /MICS/sharedprefix
where sharedprefix is the name specified on the SHAREDPREFIX
statement in sharedprefix.MICS.PARMS(JCLDEFC).  Note the
MICSLEVEL/NOMICSLEVEL option does not apply to the default
HFSROOT value.

For more information, see the Section 2.3.1.6.1 for the
HFSROOT keyword and Section 2.3.1.6 for the JCLDEFC parameter
definition member.
