Reserved AMP Worker Tasks Exclusively for Utility Jobs, Maybe
Teradata is a message passing system.  Messages are sent from parsing engines to AMPs, and from  AMPs to AMPs, and from AMPs to parsing engines.  That’s the key way that components in a shared nothing architecture pass data and work requests among themselves. When a message arrives on an AMP and the message represents work that needs to get done on the AMP, that message is assigned a“work type”, depending on the importance of the work-to-be-done.  There are 16 different work types supported:  Work00 to Work15.       Under usual conditions, all load utility jobs and all queries run using AMP worker tasks (AWTs) of the same message work types:  Work00, Work01, and Work02.  However, if you increase AWTs per AMP above a certain threshold, then all your utility jobs will be assigned to different work types and given their own reserve pools.    If you are someone who monitors or is otherwise interested in AWTs and how they are being used, this posting describes changes related to your utility jobs, and what options you have for managing these changes.

A Closer Look at Tactical Workload Exceptions
Tactical workload exceptions are in place to prevent tactical queries from consuming unreasonable amounts of resources.  It is important to have this protection because the super-priority and almost unlimited access to resources given to work running in the Tactical tier with SLES 11 is easy to abuse.

Special Treatment For Users DBC and TDWM
If you are user DBC or user TDWM and you log onto a Teradata Database, you might get treated somewhat differently than other users.  This posting describes what user DBC and user TDWM do, some of the special things about them, and when you can expect them to get treated differently.   We’ll also look at any implications in setting up workload management for these two special users.
