If you do not use the Teradata Viewpoint Workload Designer portlet to throttle concurrent load and unload jobs, the MaxLoadTasks and the MaxLoadAWT fields of the DBSControl determine the combined number of FastLoad, MultiLoad, and FastExport jobs that the system allows to run concurrently. The default is 5 concurrent jobs.
If you have the System Throttle (Category 2) rule enabled, even if there is no Utility Throttle defined, the maximum number of jobs is controlled by the Teradata dynamic workload management software and the value in MaxLoadTasks field is ignored.
For more information, see “MaxLoadTasks” and “MaxLoadAWT” in the section on DBS Control in Teradata Vantage™ - Database Utilities, B035-1102.
