FRES Command

The FRES command provides forecasting, from the database only, for the following resources:

Job workload
- Individual job resources
- Number of jobs running within a time interval
- Number of tapes required within a time interval
- Amount of memory required within a time interval
Number of workstations involved

This command has the following format:

FRES,FROM=(mmddyy,hhmm),INT=hhmm,{TO=(mmddyy,hhmm)|SPAN=hhhh}
     [,DRMODE={YES|NO}]
     [,DRCLASS=(class1,...,class8)]
     [,JOB={*|jobname|(jobname1,...jobname10)|mask}]
     [,JOBNET={*|name|mask}]
     [,LIST=list]
     [,LVL={100|nnn}]
     [,NW={*|network|network*}]
     [,SCHID={0|nnn}]
     [,STN={*|station|station*|(station1,...station10)}]
     [,SYS={*|system|mask}]
     [,TRIG={J|D|{JD|DJ}|N}]

FROM

Defines the beginning date and time for the time interval to be forecast. FROM is required.

mmddyy

Defines the date.

mm: Defines the month (01 through 12). Required. Leading zero is required.
dd: Defines the day (01 through 31). Optional. If omitted, 01 is assumed. Leading zero is required.
yy: Defines the year. Optional. If omitted, current year is assumed.

hhmm

Defines the time. Optional. If omitted, 0000 is assumed.

hh: Defines the hour (00 through 23).
mm: Defines the minute (00 through 59).

TO

Defines the ending date and time for the time interval to be forecast. TO is optional. If TO is specified, SPAN must be omitted. Either TO or SPAN must be specified.

mmddyy

Defines the date.

mm: Defines the month (01 through 12). Required. Leading zero is required.
dd: Defines the day (01 through 31). Optional. If omitted, last day of month is assumed. Leading zero is required.
yy: Defines the year. Optional. If omitted, the current year is assumed.

hhmm

Defines the time. Optional. If omitted, 2359 is assumed.

hh: Defines the hour (00 through 23).
mm: Defines the minute (00 through 59).

SPAN

Defines the length of the time interval to be forecast. This value is added to the FROM date and time-of-day to determine the ending date and time of the forecast time interval.

Limits: 1 to 4 numeric characters specified as hhhh where the minimum value is 1 hour and maximum value is 8784 hours

Required: Yes, unless TO is used

LIST

(Optional) Specifies the options for resource forecasting.

ALL: Produces all of the following choices. ALL is the default.
#JOB: Graphically displays number of jobs running during each time interval specified.
CPU: Graphically displays percent of CPU usage during each time interval specified.
GRPH: Graphically displays number of jobs running, percent of CPU used and tape usage during each time interval specified.
JOB: Produces resource forecast report for CPU workload.
STN: Produces resource forecast report for workstation workload.
TAPE: Graphically displays total number of tapes during each time interval specified.
