ORA-32827: Messaging Gateway agent must be shut down

What triggered the Error:

An operation was attempted that requires the Messaging Gateway agent to be shut down.

What should we do to fix it:

Issue SHUTDOWN, wait for MGW_GATEWAY view to show a NOT_STARTED status, and retry the operation. CLEANUP_GATEWAY may need to be issued to reset the gateway state if the agent fails to shut down after a reasonable time period.
