2.4.3.4.1 Shared DASD Analysis Report Inquiry Panel
Figure 2-91 shows the IOA Shared DASD Analysis Report inquiry
panel that you use to prepare Shared DASD Analysis Reports.
The following is a discussion of the fields on this panel.
Timespan: The specification of whether the data is to be
taken from the DETAIL or DAYS CA MICS timespan.
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 of the
CA MICS file usually contains 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 parameters.
Database: The single-character CA MICS identifiers for the
databases you want to access.
Allow The indication of whether the database
Runtime identifier and/or the Cycles specification can
Override: be overridden at inquiry execution time.
Shared
System: The SYSID of the data to be reported.
Report by The specification of whether a report should be
time generated for each interval specified or
interval: summarized into a single report.
Minimum I/O A filter for the exclusion of low I/O activity
rate: volumes. It specifies the minimum per second
I/O rate for volume inclusion in the analysis.
This value may range between 0.001 and 999.
This allows you to exclude devices that were
either unused during the interval or received
very little use. If you use this control
parameter, the I/O filter applies to all I/O
component and shared-DASD reports.
CA MICS In addition to the Minimum I/O rate, the Shared
Element DASD Analysis Report inquiry can test any other
to test: numeric data element in the HARDVA File for a
specific condition. This can be used to further
subset the data to be analyzed.
Operator The boolean operator to employ - LE, LT, GT,
to employ: or GE.
Numeric
value to The value against which the data element is
test: tested.
Date: The day(s) to be used for analysis. This field
is normally used with the IOA Shared DASD
Analysis Report inquiry to drop the extra day
from a cycle that is due to the timing of the
SMF dump.
Hour: An hour or range of hours for which data is
reported.
Zone: The specification that zone selection is to be
applied. If zone 1 definition is 8:00 a.m. to
6:00 p.m., daily reports covering that time
period can be specified by using the ZONE
field set to 1.
Specify The specification that allows you to supply
extended additional report options. These options
options: include special SAS data selection statements,
non-standard input, and output files. These
options are discussed in the sections that
follow.
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.
