Specifying the number of largest database records

Fast Path Analyzer/EP incorporates a method that allows you to specify the number of the largest database records that are tracked by the analysis process.

By default, Fast Path Analyzer/EP retains information on the 10 largest database records when you specify full pointer analysis by using the POINTER_VALIDATION keyword.

You can request a different number of largest database records by specifying a desired value on the LARGEST_DATABASE_RECORDS keyword. This keyword can be specified under any primary command that enables you to request analysis with the POINTER_VALIDATION keyword. When you specify the LARGEST_DATABASE_RECORDS keyword, the process will reserve adequate storage to track the number of largest database records that you request.

If you have activated the Fast Path Analyzer/EP statistics repository facility, the information that is gathered by the analysis process is stored in the repository for future retrieval. The information on the largest database records can also be obtained at a later time by requesting the Record Length Analysis Report from the repository using any of the available methods.

For more information, see 'Statistics repository facility'.

The example shown in the following figure will track information on the 30 largest database records contained in the specified area.

ANALYZE DBD=
dbdname,IAREA=
areaname,
  POINTER_VALIDATION=FULL,
  LARGEST_DATABASE_RECORDS=30

The example shown in the following figure will also track information on the 30 largest database records contained in the area. The REPORT subcommand is specified on the command set to generate the Record Length Analysis Report. This report will make the information available on these largest database records.

ANALYZE DBD=
dbdname,IAREA=
areaname,
    POINTER_VALIDATION=FULL,
    LARGEST_DATABASE_RECORDS=30
  REPORT REPORT_DEFAULT=NO,RECORD_LENGTH_ANALYSIS=YES
