I am going to use DB2 Auto-maintenance (AM) to help generate my table/index statistics. I doubt whether AM would slow down my server performance, even I define a maintenance window.

1) What is the 'wake-up' time that AM would update these table/index statistics? Is this parameter configurable?

2) Understand that AM would update statistics when it 'observes' that the server is not busy, however, in case the server is busy and AM cannot update statistics within the maintenance window, will AM perform statistics update outside the maintenance window?
