FORECASTING
Schedule Forecasting
A Robot SCHEDULE forecast shows you the run activity scheduled for all Robot SCHEDULE jobs over a time period you specify. To make its forecast, Robot SCHEDULE uses the job schedule, job completion history, and any information you add for user jobs, remote prerequisites, and members of remote groups. If you wish, the forecast can also include a run-time analysis of each active subsystem. The run-time analysis uses the subsystem’s description to predict job queue wait time.
Robot SCHEDULE creates a special internal forecast, *INTERNAL, automatically every time it starts and at 12-hour intervals at 11:00 and 23:00. The forecast is for 24-hour periods and is designed to be used by the Schedule Activity
Monitor (SAM) and Robot SCHEDULE job monitors. The Late start job monitor uses the *INTERNAL forecast to identify jobs that are late in starting. Because the *INTERNAL forecast is used by Robot SCHEDULE, you cannot modify or delete it. However, you can build a new *INTERNAL forecast at any time from the List view or from the Schedule Activity
Monitor. (You also can use the RBTBLDFCT command from a green screen command line). You can print the
*INTERNAL forecast from the Schedule Forecast print dialog.
You can view the forecast on the
window. The schedule forecast list shows each job scheduled to run during the forecast period with its start time and its expected run time. You can
by changing start times and run times, and by holding, releasing, and deleting jobs. These options allow you to perform “what if” scenarios without affecting your schedule.
If you wish, you also can
update the actual Robot SCHEDULE job record
. The update can hold or release the job or change its start time, but it cannot delete the job or change its run time.

Forecasting / Creating Forecasts
Creating Forecasts
The forecast is based on the job schedule, run history, and run-time analysis of each active subsystem. (The run-time analysis uses the subsystem’s description to predict job queue wait time.) You can schedule the build on Robot
SCHEDULE or build it in batch. The forecast period begins when the forecast is run and continues for the time specified, or the period defined by the start and end times.
To create a new job forecast:
1. Right-click Forecast Objects and select New. The Create Forecast window displays.
2. Enter a name and description for the forecast. If you accept the defaults (*GEN and *FCT), Robot SCHEDULE generates a name using a 10-character format. The first character is F (for forecast), followed by a 6-digit date using the date format of the job that builds the forecast, followed by a 3-digit sequence number. The description is identical to the forecast name.
Note: If you build a forecast using an existing forecast name, the new forecast overwrites the old one.
3. Define the time parameters for your forecast. You can choose from Forecast Length or Forecast Period:
Select Forecast Length to specify the length of time for the forecast in days (up to 999) or hours (up to
999). The forecast time period begins when the build is submitted.
Select Forecast Period to specify a date and time range. Enter the beginning and ending dates and times for the forecast.
4. The Create Forecast window lists the subsystems on your system that are currently active. You can add or remove subsystems that are included in the forecast.
To add a subsystem, click Add. If you select to add a subsystem, the Subsystem Finder displays so you can select a subsystem.
To remove a subsystem, select the subsystem and click Remove.
5. Click the Schedule button to schedule the forecast build in Robot SCHEDULE.
Robot SCHEDULE forecasts based on a run-time analysis of all of the subsystems listed.
Adding Non-Robot SCHEDULE Jobs to a Forecast
Initially, a forecast uses only the information from the Robot SCHEDULE job schedule and Robot SCHEDULE job completion history. For a more complete forecast, you can add other jobs that will run during the forecast period.
To add a job to the forecast, right-click Schedules for Forecasting and select New. Select the type of job you want to add from the Create Forecast Schedule window.
Adding Remote Prerequisite Jobs to a Forecast
If you are forecasting a job that has a prerequisite on a remote system, you can add the prerequisite job schedule to get a more accurate forecast.
1. Select Remote prerequisite on the Create Forecast Schedule window.
2. The Select a Job finder lists the jobs on all systems that are prerequisites to jobs on your system. Select the job you want to add to the forecast.
3. The Job Properties window for the selected job displays, allowing you to edit the schedule of the job.
4. Click OK when you are done to add the job to the forecast schedule.

. It monitors for an event (file/directory/member change) that occurs on the IBM i system you're connected to.
Schedule Forecast List
The Schedule Forecast List window displays each job scheduled to run during the forecast period with its start time and expected duration. The expected duration is a moving average of the job’s past run times. You can adjust the forecast by changing its start times and duration. You can also update the actual Robot SCHEDULE job record to hold or release the job or change its start time.
Use the Subsystem, Job Queue, and Data Filters to display only the jobs you want to see.
Right-click a job in the table to display the following menu options for working with the job:
Edit Forecast Properties: You can change the start times and duration for a job on the Forecast Properties dialog.
Changes you make to these values are stored with the forecast; they are not used when you build a new forecast.
Note: If you change any information in this window, you should recalculate the forecast (see Recalculating a
Forecast, later in this section).
Remove From Forecast: You can remove a job from the schedule forecast. You should recalculate the forecast if you remove a job.
Job Run History: Select Job Run History to display the Job Run History window. The information shown includes details about the job’s start date and time, the actual elapsed time, and the forecast elapsed time. You can change the forecast elapsed time for the job. This is useful if the job’s average duration is skewed because of a particularly short run due to abnormal termination or a long run due to various reasons and you want to use its normal run time in the forecast. Robot SCHEDULE uses the average of the run times stored in history to calculate the run time for this job when you build a new forecast.
To change the elapsed time for the forecast, select a forecast, right-click, and select Edit Forecast Elapsed Time.
Use the Forecast Properties window to enter the new elapsed time you want the forecast to use.
Recalculating Forecasts
Anytime you change the start times or duration for jobs, or the actual jobs contained in the schedule forecast, you should recalculate the forecast. This process may take some time.
To recalculate a forecast, select the forecast and select Recalculate. A confirmation dialog box displays asking you to verify that you want to start the recalculation process.
