XAXIS control statement
The XAXIS control statement selects records from the IRUF file and defines the X-axis. XAXIS statements must precede any SELECT statement.
The XAXIS statements define the records to be used for a plot request. DATE and TIME parameters request record selection by date and time and specify the X-axis units of measurement to be in days or hours.
XAXIS=[(DATE=nnnnn/nnnnn|TIME=hh.mm/hh.mm,INTERVAL=nn,SYSTEM=x|ALL,REGNTYPE=xxx)]
The order of the parameters in the XAXIS statement determines the XAXIS span. If DATE is before TIME, the X-axis range is in days. If TIME is before DATE, the X-axis range is in hours. If no DATE or TIME is specified, the default for the X-axis measurement is TIME. INTERVAL defines the length of the X-axis. SYSTEM and REGNTYPE are global selections.
REGNTYPE=ALL must be specified to plot DBCTL thread information.
Parameter | Description |
|---|---|
DATE | Requests IRUF record selection by day or range of days If DATE is specified before TIME, the X-axis measurement is set to the defined days. A range is defined by a slash sign (/) between two integers. The integer can be a value from 00000 to 99365. One day’s activity is reported if only one integer is specified, such as DATE=07105. If DATE is not specified, the default is 00000/99365 (all activity). The day plot can be produced from detailed or daily summarized IRUFs. For example, an input of seven detailed IRUFs from one week of processing can show the total week’s activity by day for the seven-day input. A plot by DATE, showing the weeks in the year, could be produced from weekly summarized IRUFs. |
TIME | Requests IRUF record selection by hour or range of hours If TIME is specified before DATE, the X-axis measurement is set to the defined hours. The range is defined by a slash (/) sign between two integers. The integer value defines hours and hundredths of hours. Hundredths of hours is optional. If only one integer is specified, such as TIME=2, the default is 2.00/2.99 (one hour of activity). If TIME is not specified, the default is 00.00/23.99 (all activity). The time plot can be produced only from detailed IRUFs. If you try to produce a plot by TIME from a summarized IRUF, you will get a diagnostic code 03 (see Diagnostic-codes-for-PRSPLT00). If the input IRUF contains more than 24 hours of data, some time intervals reflect more than one day’s data. For example, if seven detailed IRUFs from one week of processing are used as input, a plot by TIME could show the total week’s activity by time slices, such as the hour from 10:00 A.M. to 11:00 A.M. for all seven days. |
INTERVAL | Specifies a numeric value from 0 to 999 that defines the X-axis length and unit increments A maximum of 100 columns can be defined per page. If more than 100 columns is specified, multiple pages are produced. The default is 96. If TIME is specified, the unit increments for each column are number of hours. This value is calculated by dividing the X-axis elapsed time (defined by DATE or TIME range) by the specified INTERVAL value. For example, the TIME default of TIME=00.00/23.99 and the INTERVAL default of INTERVAL=96 produces a plot with 96 X-axis columns representing 15 minutes each (24 hours × 60 minutes ÷ 96). A plot request of DATE=07001/07091 with INTERVAL=91 defines each X-axis column as one day. If you change the request to INTERVAL=13, each X-axis column is defined as one week. For best results, the input summarization should match the desired granularity of the X-axis. |
SYSTEM | Specifies a single alphanumeric character for a specific IMS ID or the character string ALL for all IMS IDs Transactions with system IDs that do not match the SYSTEM value will not be selected for plotting. The default is ALL. |
REGNTYPE | Specifies a region type Only transactions or programs that executed in the specified region type will be plotted. The regions are specified as follows:
