Teradata Vantage™
To limit the resources used by an active map reassignment job, reduce the number of sessions processing the map use changes. In the following example, it is now 8 a.m., the system is busy, and the DBA stops 5 of the 8 Mover sessions that started at 6 p.m. last night:
CALL TDMaps.StopMoverSP(5);

StopMoverSP does not abort any ALTER TABLE requests in progress.

For more information on StopMoverSP, including the syntax, see Teradata Vantage™ - SQL Operators and User-Defined Functions, B035-1210.
