2.4.7.4.1 Tape Drive Simulation Analysis Inquiry Panel
Figure 2-150 shows the IOA Tape Drive Simulation Analysis
Inquiry Panel. The following fields are used on that panel:
Timespan: The specification that the data is to be taken
from the DETAIL 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 from 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 REPORT DATE and HOUR parameters.
Database: The single character CA MICS identifier for the
database you want to access.
Include Code a Y (Yes) if the BATPGM File is required in
batch pgms: the analysis.
Include
system Code a Y (Yes) if the BAT_ST File is required in
tasks: the analysis.
Include Code a Y (Yes) if the BAT_TS File is required in
TSO users: the analysis. Normally TSO users are restricted
from tape use.
Include Code a Y (Yes) if the BAT_TP File is required in
APPC TPs: the analysis.
Merge Code a Y (Yes) if you want reporting on the
SMF JOB variables JOBCLASS, JOBMCLS, JOBINQTM, or
info: JOBFETTM.
Report date, Two time selection methods are provided to
Report allow analysis on a subset of the input data
hours, and to restrict reporting to times under current
Hour analysis.
Selection:
The input data is first limited to a range of
data to be selected by the specification of the
Hour Data Selection parameter. Range
specification is required due to the nature of
the data source (see Section 2.4.7.2.1, Data
Limitations).
Report date and report hour fields define the
data to be presented in the reports.
Report
level: Either a SUMMARY or DETAIL report.
JES The specification of whether 2 (JES2 step
version: allocation) or 3 (JES3 high watermark) device
scheduling is to be analyzed. The default is
2. The differences between these two methods of
scheduling tape device allocation are described
in Sections 7.7 and 2.4.7.2
Anal. Either the snapshot or the prorating analytical
method: method. The default is SNAPSHOT. These two
methods are described in Section 2.4.7.2.
Sampling The number of minutes in each sampling interval
intv.: for this analysis. The default is one minute.
If you choose the SNAPSHOT analytical method, an
interval greater than two minutes will be
flagged as an error. If you choose the PRORATE
method and you specify an interval greater than
59 minutes, subsequent reports will be by day
rather than by hour within day.
Max. Specifies the maximum scale for the summary bar
tapes: chart report for this analysis. This could,
if you wish, be set to the maximum number of
drives available. The default is the actual
maximum number of drives allocated during any
particular hour analyzed. Thus the default
changes for each hour's bar chart.
Chart The exception limit for the summary reports for
reference this analysis. This could, if you wish, be set
line and to the maximum number of drives that operations
limit: experience has found can be allocated without
causing extra operator activity in retaining and
remounting tapes. There is no default. If this
parameter is not specified, or if the data
analyzed does not exceed this limit, no Summary
Exception Report will be produced. If specified
as 0, the Summary Exception Report will display
all data for workloads using tape drives.
Sysid: Specifies the SYSIDs of the data to be analyzed.
Specify The specification that allows you to supply
extended additional report options. These options
options: include special SAS data selection statements
and USER modeling exits, non-standard input and
output files, Add and Move workload observation,
and a panel to describe additional reporting
elements.
The operation of the time selection control parameters
depends on definitions made during the installation of
CA MICS.
