3.2.3 IBM Hydra MICF Inquiries

 Reports for IBM Hydra TS7700 series virtual tape servers are
 distributed as MICF inquiries and are listed in Figure 3-4.
 
 All of the IBM Hydra inquiries generate line-printer reports.
 Samples of each report are presented in the following
 sections.
 
 All reports can be produced at multiple summarization levels.
 Dates and titles are adjusted appropriately based on the
 timespan and summarization level that is selected 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 shows 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 (IBM VTS) or S
              (StorageTek VSM).
 
 n =          A character that differentiates this inquiry
              from others.
 
 For example, an inquiry named TAPLVC would be interpreted
 as follows:
 
                  TAPLHC
                  ---||+= the third list inquiry
                   | ||
                   | |+= for IBM Hydra TS7700 Series Servers
                   | |
                   | += a list inquiry
                   |
                   += a Tape Analyzer Option inquiry
