The MICF inquiries for StorageTek VSM virtual tape systems
distributed with the VTS component are listed in Figure 3-11.
All of the StorageTek VSM inquiries generate line-printer
reports. Samples of each report are presented in the
following sections.
Most reports can be produced at multiple summarization
levels. Dates and titles are adjusted appropriately based on
the timespan and summarization level chosen for the
execution. After data has been collected for a time period,
this summarization capability can be used to "drill down" to
a specific time frame.
For example, production trend reporting can be done at the
WEEKS timespan level for the most recent 26 weeks. If the
report from last week's data showed erratic behavior at the
weekly level, the same report can be used to drill down to
the DAYS and DAYS by HOUR level, to determine the specific
interval where the abnormal behavior occurred.
User Modification
-----------------
The MICF inquiries provide a user exit in the independent
source step that can be used to perform more data element
modification or record selection from the CA MICS database.
To invoke this exit, the shared inquiry must first be copied
into the private MICF catalog, then selected for
modification. Finally, the SAS statements must be coded in
the SELECT macro, bracketed by the %MACRO and %MEND
statements, which are provided.
The default for the SELECT macro is null. This macro is
invoked when the observations are read from the specified CA
MICS files. The macro can be used to delete observations
from the data as it is processed. For example, for a
published study, you can change the actual VTS Library
Sequence Numbers (IVTVLS) and VTS Composite Library ID
(IVTCMPID) values that appear in the report. The following
code would accomplish this requirement:
%MACRO SELECT;
IF IVTVLS = 'PROD01' THEN IVTVLS ='VTS001' ;
IF IVTCMPID = 'PRDC01' THEN IVTCMPID ='CMP001' ;
... additional remapping statements ...
%MEND SELECT;
Use this macro to exclude systems from the report, for
example, exclude all test systems:
%MACRO SELECT;
IF SYSID NE: 'T';
%MEND SELECT;
IMPORTANT! All SAS statements must be coded in accordance
with the syntax of the SAS Macro Language, as described in
the SAS guides. No validity checking is done on the defined
code. If the user code contains syntax errors or the logic
produces syntax errors, the inquiry is either terminated
abnormally or produces unpredictable results.
Inquiry Naming Conventions
--------------------------
The VTS component MICF inquiry names follow the form cccptn,
where:
ccc = The three-character product identifier (TAP).
p = The type of report: C (color graphic), L (list),
or P (printer).
t = The technology reported on: V for IBM VTS or S
for StorageTek VSM.
n = A character that differentiates this inquiry
from others.
For example, an inquiry named TAPLSA would be interpreted
as follows:
TAPLSA ---||+= the first list inquiry | || | |+= for StorageTek VSM | | | += a list inquiry | += a Tape Analyzer Option inquiry +--------------+----------------------------------------------+----------+ | Report Class | Report Name | Report ID| +--------------+----------------------------------------------+----------+ | Perform | StorageTek VSM Virtual Tape Mount Report | TAPLSA | | | StorageTek VSM Disk Buffer Usage Chart | TAPPSB | | | StorageTek VSM VTSS System Capacity Summary | TAPLSC | | | StorageTek VSM VTD Usage Summary | TAPLSD | | | StorageTek VSM RTD Usage Summary | TAPLSE | | | StorageTek VSM VTD Mount Time Distribution | TAPPSF | | | StorageTek VSM RTD Mount Time Distribution | TAPPSG | | | StorageTek VSM Recalled VTV Age Distribution | TAPLSH | +--------------+----------------------------------------------+----------+
