If your installation produces large volumes of messages for operators to monitor, it is a good idea to use the action message retention facility (AMRF). If you want operators to be able to retrieve action messages and WTOR messages that no longer appear on the console, use AMRF. AMRF keeps action messages so that the operator has a chance to see them at a later time. WTOR messages are always available for operator retrieval regardless of the state of AMRF.
