Note that this parameter is optional. If you do not want to
define performance groups, (for example if your operating
system is running in goal mode), simply code an empty member,
or use the default member delivered with CA MICS.
Some components, such as the VM Component and SNT Component,
do not use performance groups because this information is not
provided in the data source. For any SYSID that is
exclusively associated with a component that does not use
performance group, no entry in the Performance Group Names
Table is necessary. The table must be present even though it
may contain no entries (i.e., only comments).
In prefix.MICS.PARMS(PRFGP), you are asked to supply
character string names which CA MICS can carry in the
database along with the corresponding performance group
numbers. (This name is carried in the data element named
PERFGRPN.)
Figure 2-13 illustrates a sample performance group
number-to-name mapping.

Figure 2-13. Sample Performance Group Name Definition
In assigning names to your performance groups, you are
dependent on the specifications in your Installation
Performance Specifications (IPS), the Installation Control
Specifications (ICS--SE-2 level MVS and above), and on
whether your shop is careful to run various workloads in the
performance groups that are defined for them. Fortunately,
this is not a problem in the majority of sites.
The form shown in Figure 2-14 may be used to gather the data
you need to complete prefix.MICS.PARMS(PRFGP). In order to
complete this form, get a current copy of all the
Installation Performance Specifications (IPSs) and
Installation Control Specifications (ICSs--SE2 and above
levels of MVS only). They are stored as members of
SYS1.PARMLIB with member names of the form IEAIPSxx and
IEAICSxx, respectively. With these in hand, you will be able
to code prefix.MICS.PARMS(PRFGP) according to the following
rules:
One line is to be coded for each performance group.
Comments are coded by beginning the statement with an
asterisk (*).
Rather than coding these parameters from scratch, you
should modify the sample PRFGP member provided in the
prefix.MICS.PARMS library shipped with the system to
reflect your definitions. Starting with an existing,
correct member may spare you annoying syntax mistakes.
The format of the statements is free-form, but positional.
Statements have the following form:
sysid nn 'name of performance group nn'
The parameters are:
System Identifier (sysid):
The system identifier of the system for which this
performance group is being defined. Note that this is
the logical SYSID defined for the system in
prefix.MICS.PARMS member name SYSID.
PERFORMANCE GROUP NUMBER (0-9999):
The performance group number defined within the
Installation Performance Specifications (IPS) for
control performance groups and within the Installation
Control Specifications (ICS) for report performance
groups. Report performance groups are only available
with MVS/SE2 and above releases.
PERFORMANCE GROUP NAME:
The one- to eight-character name, enclosed in single
quotes, which is carried in the database along with the
number to identify a given workload associated with a
performance group number.
We recommend that you supply a name for every performance
group number which even MIGHT be used. However, this is not
mandatory. If CA MICS encounters a performance group number
to which no name has been assigned, a name of the form 'GROUP
nn' is generated.
