The Analyze Performance Data (ANZPFRDTA) command produces recommendations to improve the performance of the user's system. In the interactive mode, you can request that the system make the recommended changes. In the batch mode, the recommended changes are printed, and you must then enter the individual commands to make the recommended changes.

Top

Member (MBR)

Specifies the member that contains the performance data collected by Collections Services from the Operations Navigator interface.

*SELECT

An interval selection display is shown from which you can select one or more intervals for inclusion. This value is valid only in the interactive mode.

member-name

Specify the name of the member containing the performance data.

Library (LIB)

Specifies the library where the performance data is located.

QPFRDATA

The performance data files are located in the IBM-supplied performance data library, QPFRDATA.

library-name

Specify the name of the library where the performance database files are located.

Output (OUTPUT)

Specifies whether the output is printed or displayed.

*

Output requested by an interactive job is shown on the display. Output requested by a batch job is printed with the job's spooled output.

*PRINT

The output is printed with the job's spooled output.

Time period for report (PERIOD)

Specifies the period of time on which to report. The parameter consists of four elements: a starting time and date, and an ending time and date. Data collected prior to the starting time on the starting date and after the ending time on the ending date is not included in the report.

The symbol *N can be used to designate the default value for any of the four elements.

The possible starting time values are:

*FIRST

Data records starting from the beginning of the first day (00:00:00) of the collection period are included.

*SELECT

An interval selection screen is displayed from which you can select one or more intervals for inclusion. This value is valid only in the interactive environment. If this value is used, the remaining values of this parameter (starting time and date and ending time and date) are ignored.

start-time

Specify the time of the first data record to include in the report, using the format, hhmm or hhmmss, where hh is the hours, mm is the minutes, and ss is the seconds.

The time is specified in 24-hour format with or without a time separator:

• Without a time separator, specify a string of 4 or 6 digits (hhmm or hhmmss) where hh = hours, mm = minutes, and ss = seconds.
• With a time separator, specify a string of 5 or 8 digits where the time separator specified for your job is used to separate the hours, minutes, and seconds. If you enter this command from the command line, the string must be enclosed in apostrophes. If a time separator other than the separator specified for your job is used, this command will fail.

All time and date entries must be 2-digits in length, meaning zeros must be included.

The possible starting date values are:

*FIRST

Data records starting from the first day of the collection period are included in the report.

start-date

Specify the date of the first data record to include in the report. The date must be entered in the format specified by the system value QDATFMT, and if separators are used, as specified by the system value QDATSEP.

The possible ending time values are:

*LAST

Data records through the end of the day (23:59:59) are included in the report.

end-time

Specify the time of the last data record to include in the report. Use the same format used for the starting time.

The possible ending date values are:

*LAST

Data records through the last day of the collection period are included in the report.

end-date

Specify the date of the last record to include in the report. The date must be entered in the format specified by the system value QDATFMT, and if separators are used, as specified by the system value QDATSEP.

Report option (DATATYPE)

Specifies the type of data that is analyzed.

*ALL

All data (sample data and trace data) is analyzed.

*SAMPLE

Only sample data is analyzed.

Examples
