2.8.5 Component Operation
This Component Operation Section describes the operation of
the sysplex analysis routines in terms of the CA MICS MVS
Performance Manager inquiry options selected.
Inquiry options available with the sysplex analysis software
describe the reports to be generated. In particular, these
options define:
o The cycles from the CA MICS RMF files to be processed.
o Workload selection by system (SYSID), XCF system,
XCF member, XCF group, Coupling Facility structure,
date/time, and zone.
o The summarization level of the reports as hourly, daily,
weekly, or monthly. The availability of each
summarization level assumes that your system supports
the required files at each level.
o The reports to be produced.
The following fields are common to most control screens:
Timespan: The timespan (DETAIL, DAYS, WEEKS, or MONTHS)
in the CA MICS file(s) you want to use as input
for processing.
Cycle(s): One or more cycles of the CA MICS files
that you want to use for analysis. Because SMF
data sets are not normally dumped at exactly
midnight at most installations, a CYCLE from the
CA MICS file will usually contain a 24-hour
period spanning two days. Hence, some other
type of selection may be required to generate a
daily report. This selection capability is
provided by the DATE and HOUR control options.
Database: The single-character CA MICS identifier for the
database to be accessed. Valid values are the
database unit identifiers available at your
installation. Contact your CA MICS System
Administrator if you do not know what database
units are available, or enter a question mark
(?) to view a list of your database units.
You can select up to five databases per
inquiry.
Allow The indication of whether the database
Run-Time identifier and/or the Cycles specification can
Override: be overridden at execution time.
Report by The indication of whether a report or plot
hour: should be generated for each hour.
Generate a The indication of whether a separate report or
report for plot should be generated for each zone defined
each value in the input data or whether all zones should
of Zone: be merged together for the report or plot.
Date: Up to two date ranges (DDMONYY format) to be
used for analysis. This option is normally used
to drop the extra day from a cycle that is due
to the timing of the SMF dump.
Hour: One to three ranges of hours for which data is
to be reported. For an individual hour, leave
the end hour blank or make it the same as the
start hour. You can specify a value from 00 to
23.
Zone: The specification that zone selection is to be
applied. If zone 1 definition is 8:00 a.m. to
6:00 p.m., you can specify reports covering that
time period by entering a 1 in the ZONE field.
SYSID: The specification that SYSIDs are to be selected
for reporting. You can enter up to six SYSIDs
to be selected. If you leave the field blank,
no testing of SYSIDs will be done.
Systems: The XCF systems to be selected for reporting.
If you code this field, only those systems
specified will be selected.
Groups: The XCF member group(s) to be selected for
reporting. If you code this field, only those
specified will be selected.
Members: The XCF member(s) to be selected for reporting.
If you code this field, only those specified
will be selected.
Structures: The Coupling Facility Structures to be reported.
If code this field, only those specified will be
selected.
Specify The specification that allows you to supply
extended additional report specifications. These options
options: include special SAS data selection statements,
nonstandard input and output files, and special
graphics options.
The operation of the time selection control parameters
depends on definitions made during the installation of
CA MICS. If you are not sure about the ZONE definitions
for your installation or the CA MICS database update
procedures, consult your CA MICS System Administrator.
Figure 2-215 shows the Sysplex (SPA) Analysis menu that you
use to select the desired report within the Sysplex reporting
area.
