TUNED reports

The FPA Tune function generates reports that begin with TUNED in the title. The contents of the reports are the same as the reports generated by other functions of FPA except that these TUNED reports contain information that is obtained from simulated areas.

The following reports can be generated by the Tune function:

TUNED Consolidated Largest Database Records report

Use this report to analyze the largest database records in the simulated areas. The report provides information about each of the large database records, starting with the largest database record.

To generate this report, specify the TUNE command with the following keywords on the REPORT subcommand:
  • LARGEREC_REPORT=YES
  • LARGEREC_COUNT=(parameter1,parameter2)

    For parameter2, specify a value that is equal to or lager than 1.

For an example and contents of the Consolidated Largest Database Records report, see Consolidated Largest Database Records report.

TUNED DB Record Length Distribution report

The optional report for database record analysis provides database record distribution broken down into 20 CI size ranges.

To generate this report, specify the TUNE command with the DBRLDIST=YES keyword on the REPORT subcommand.

For an example and contents of the DB Record Length Distribution report, see DB Record Length Distribution report.

TUNED DEDB Area Analysis reports

The TUNED DEDB Area Analysis reports include the comprehensive analysis information obtained from the simulated area.

The TUNED DEDB Area Analysis reports include the following reports:
  • Freespace Analysis report
  • DB Record Profile Analysis report
  • DB Record Placement Analysis report
  • Segment Placement Analysis report
  • Segment I/O Analysis report
  • Synonym Chain Analysis report

These reports are always generated if the TUNE command is specified.

In the Freespace Analysis report of the TUNED DEDB Area Analysis reports (generated for the simulated areas), fields PTR. TO DOVF and PTR. TO IOVF are different from the fields in the Freespace Analysis report of the DEDB Area Analysis reports (generated for the current areas). In the report that is generated for the simulated areas, the fields display the number of PTF pointers and PCF pointers that point to the DOVF and IOVF sections, whereas the fields in the report that is generated for the current areas display the number of PTR pointers, PCF pointers, PCL pointers, and SSP pointers that point to the DOVF and IOVF sections.

For examples and contents of these reports, see DEDB Area Analysis reports.

TUNED Largest Database Records report

Use this report to analyze the largest database records. This report provides a description for each of the large database records, starting with the largest database record, obtained from the simulated area.

To generate this report, specify the TUNE command with the LARGEREC_REPORT=YES keyword on the REPORT subcommand.

For an example and contents of the Largest Database Records report, see Largest Database Records report.

TUNED Process Summary of Analysis report

The Process Summary of Analysis report contains the processing information of the analysis report. An echo of the control statement that you specified in the HFPAPARM and some processing messages are issued in this report.

This report is always generated if the TUNE command is specified.

For an example and contents of the Process Summary of Analysis report, see Process Summary report.

TUNED Segment Length Distribution report

This report provides detailed information about each segment in the simulated area. You can use this report to analyze the segments. The Segment Length Distribution report can be used to:
  • List detailed information about each segment
  • Identify which segment requires tuning

To generate this report, specify the TUNE command with the SEGLDIST=YES keyword on the REPORT subcommand.

For an example and contents of the Segment Length Distribution report, see Segment Length Distribution report.

TUNED UOW report

This report provides detailed information about each UOW in the simulated area.

You can use this report to:
  • List detailed information about each UOW
  • Identify which UOWs require reorganization
  • Manage space utilization when the randomizer has been modified to group related data into contiguous UOWs
  • List only those UOWs that violate the space utilization criteria that you specified

This report is always generated for the TUNE command unless the UOW_REPORT=NO keyword is specified on the REPORT subcommand.

For an example and contents of the UOW report, see UOW report.

TUNED UOW Exception report

This report contains the analysis information of the UOW that exceeds the user-specified reporting parameters in the simulated area.

You can use this report to:

  • List detailed information about each UOW
  • Identify which UOWs require reorganization
  • Manage space utilization when the randomizer has been modified to group related data into contiguous UOWs
  • List only those UOWs that violate the user-specified space utilization criteria

This report is generated by the TUNE command and by the reporting parameters that you specify on the HFPAPARM DD statement.

For an example and contents of the UOW Exception report, see UOW Exception report.
