If you prefer not to run with the default actions, you have two options:
Always operate your system in attended mode. AMS does not execute default actions in attended mode. You can automate actions while operating in this mode by using the OM keyin to turn on the AAMS option.
Define patterns in the AMS database to cover all of the affected messages and provide the actions you defined. In the event of database corruption or if you omitted a message, you still have basic system functionality.
