Operational Feature/Function


Concurrent Load Utility Tasks

The maximum number of concurrent FastExport tasks that can run is variable; the limit can be controlled by the system administrator. MaxLoadTasks may be overridden if TASM is active.

Note: For the most up‑to‑date information on concurrent task limits see Utilities (B035‑1102). Additional information is also available in the Teradata Dynamic Workload Manager User Guide (B035‑2513).

If a FastExport job exceeds the recommended limits, Teradata Database returns a 2633 error message indicating that too many loads are running, and the utility retries until:

  • It can execute the task
  • It reaches the TENACITY hours time limit specified by the BEGIN EXPORT command
  • Exponential operators
