These forecasting commands display, in reports and graphs, resource forecasts for successive short time intervals throughout the forecast time period. These resources include percentage of CPU, number of tapes (for each type), and number of workstations.
For the FQRES function, the work for resource forecasting is selected from the CA Workload Automation SE queues and from the database. The selection is made from the queues first. Later, if the forecast time period is large enough, further selection is made from the database.
For the FRES function, the work is selected only from the database.
In both cases, selection from the database is done according to the start time. Specify start time either explicitly or imply by due-out time minus average elapsed time. The selection is made if the start time falls within the time interval of the forecast. Optionally, any jobs triggered by the selected jobs or any workstation in the output networks connected to these jobs are also included.
A forecast can be done for any resolved time interval, and it can be in online or batch mode. However, as the forecast time interval is increased, the response time in online mode can lengthen, the output volume can become larger, or both. These forecast functions use the CA Workload Automation SE scratch queue. Consider increasing the allocated space for this file, depending on the size of the database and the time interval of the forecast. See SWFTRK parameter on the DAIO initialization file statement.
Forecast selection can be made from the database by job, system, workstation, or network and indicated by specific or generic names. Specific names are specified in up to eight characters, and generic names are specified in up to seven characters and terminated with an asterisk (*).
