Description:

OPSMVS will not be affected since we do not pay attention to the automation processing bit they would be setting.

Solution:

Message Flood Automation is implemented as a Message Processing Facility (MPF) IEAVMXIT routine that is called as a part of z/OS WTO processing. The exit examines each message in the z/OS system, and attempts to identify when too many WTOs are being issued and by whom. It then takes appropriate action - usually to suppress the message from display at a z/OS console, and to indicate that automation processing is not required. It can also issue commands e.g. to cancel the user or process.

OPSMVS will not be affected since we do not pay attention to the automation processing bit they would be setting.

Message Flood Automation suppresses message from the consoles not the SSI. If you need to send messages to consoles you can add up to 30 messages (no wildcards) to ignore for MFA.

Example:
