The RESTART TPA command, available from Database Window (DBW), is similar to TPA Reset, in that it resets and restarts Teradata Database. However, RESTART TPA lacks several of the options of TPA Reset. For example, RESTART TPA cannot be used to shut down the PDE component of Teradata Database. For more information about DBW, see Database Window (xdbw).
TPA Reset can only be run on nodes where PDE is running.
