Automatic Tuple Mover (ATM)
The Automatic Tuple Mover (ATM) refers to the Tuple Mover operations that occur automatically at regular intervals set by configuration parameters. For example, two configuration parameters control the TM mergeout and moveout intervals, which are both ATM activities. Conversely, invoking the do_tm_task function is not an ATM activity. For information about changing the TM configuration parameters, see Tuple Mover Parameters in the for further information.
