3.1.1 Selecting the Runtime Parameters

VCC offers a set of parameters that can be used to tailor VCC
to your reporting needs.  Parameters also have been provided
to tune internal VCC constants that deal with VCC operating
speed and the consumption of virtual storage.

These parameters apply to both standard VCC collection and
HFS collection. The parameter descriptions are supplied in
Section 3.1.1.2.  To the right of each parameter name, it is
specified whether the parameter is for standard VCC
collection, HFS collection, or both.

The choice of parameters depends largely on your research
during the VCC planning phase (see Chapter 2).  The parameter
data set can be a member of a partitioned, sequential, or "DD
*" data set.  The data set must be fixed blocked, physical
sequential, with a logical record length of 80.  This data
set is referenced by the VCCPARMS DD statement (see Section
3.1.2).  If the VCCPARMS DD statement is absent, then VCC
will run using parameter defaults.
