FALL Command

The FALL command provides forecasting for jobs and network workstations. Only the database is used for this forecast.

This command has the following format:

FROM

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

TO

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

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. If you code the LIST option, you must also specify the RINT option.

ALL: Produces all of the following choices. With this option, TAPE1 displays separately from TAPE2. 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 the number of tapes (both TAPE1 and TAPE2) forecasted for each time interval specified.

SCHID

(Optional) Defines the schedule ID as a value 1-255 to be used in the forecast. Required only if the job being forecasted does not have a schedule.
