Introduction › Forecasting › Forecasting Tape Requirements › Commands

Commands

These forecasting commands produce reports indicating the volume serial numbers of the input tapes needed for jobs during the specified forecast time period. The jobs used for FTAPE are selected only from the CA Workload Automation SE database. For FQTAPE, the jobs used to produce tape pull lists are selected from the CA Workload Automation SE queues and from the database. Selection is made from the queues first. Then, if the forecast period is large enough, further selection is made from the database.

The selection from the database in both cases is done according to the start time. Specify start time either explicitly or imply due-out time minus average elapsed time. The selection is made if the start time falls within the time interval of the forecast. Any jobs triggered by the selected jobs are also optionally included. Once the job is selected, the database is searched for any data set residing on tape. CA Workload Automation SE entries, and system catalog entries, are searched to find the appropriate volume serial numbers of the tapes.

Forecast selection can be made from the database by either job name or system name. These names can be specific or generic. Specific names are specified in up to eight characters, and generic names are specified in up to seven characters and terminated with an asterisk (*).

Note: The JCL for selected jobs is not examined, only the database information. Therefore, temporary changes made to JCL regarding VOLSER values are not reflected in the forecast unless the job is reloaded.

The order of the JCL within a step is important to whether a particular tape data set is forecasted. Consider two DD statements referring to the same data set (for example, a GDG), one for input and the other for output. If the input DD statement comes before the output DD statement, the data set is considered as a requirement and forecasts. Otherwise, it does not.

FTAPE

Tape pull list for jobs.

FQTAPE

Tape pull list for jobs including those jobs in the CA Workload Automation SE queues.
