Purpose

Specifies the number of AMP Worker Tasks (AWTs) that can be used by the MultiLoad Extended Protocol (MLOADX) at any time. It allows more tasks (jobs) to run concurrently, and sets a limit on AWT usage to prevent excessive consumption or exhaustion of AWT resources.

AWT Resource Limit rules set in the Teradata Viewpoint Workload Designer portlet override the MaxMLOADXAWT setting.

Field Group

General

Valid Settings

0 through 70% of the number of AWTs started per AMP on your system.

The number of AWTs started per AMP is normally 80, however this can be modified by Teradata Support personnel for special circumstances.

Default

60% of the number of AWTs started per AMP.

Because there are usually 80 AWTs started per AMP, the default value for MaxLoadAWT is typically 48.

Changes Take Effect

After the DBS Control Record has been written.

Usage Notes

This field is enforced only when MLOADXUtilityLimits is set to TRUE. In these cases, the setting of MaxLoadAWT does not apply to MLOADX jobs.

This field is ignored if the throttles category set in the Teradata Viewpoint Workload Designer portlet is enabled.
