ATM operator commands can be issued by the operator in the normal way or from the Online Services application.

The following operator commands are supported by an ATM transaction manager:

Command	Description
ATM DSTAT	In response to this command, the TM will display transaction statistics.
ATM END	This command requests an orderly shutdown of the TM. New distributed transactions will be prevented from starting. In-flight distributed transactions will be allowed to complete, at which point the TM will terminate. Note: The TM will be requested to perform an implicit ATM END when an ADAEND is issued directly to the Adabas System Coordinator daemon (/f taskname,ADAEND).
ATM HALT	This command requests an immediate shutdown of the TM. New distributed transactions will be prevented from starting. In-flight distributed transactions will be terminated without waiting for completion. Recovery of incomplete transactions occurs during restart.
ATM RSTAT	In response to this command, the TM resets all of its statistical counts to zero. A message appears on the console confirming that statistics have been reset.
ATM STOPU=’jobname’	This command asks the TM to perform a "stop" operation for all transactions belonging to clients with the given jobname. The TM will attempt to terminate such transactions by backing them out, or (if the commit decision has already been taken) committing them, then it will discard its knowledge of any transactions that were successfully terminated. An ATM082 message will appear on the console to indicate that this operation was requested by the operator.
