MaxLoadTasks and the MaxLoadAWT determine the combined number of MultiLoad and FastExport jobs that the system allows to run concurrently. The default is 5 concurrent jobs. To modify this setting, contact Teradata Support for assistance.
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.
