We are currently building our EM12c environment and real-time ADDM/hang analysis is one of the new features we are looking to try out. Has anyone come across a white paper to try out this functionality? I suppose I'm more looking for various methods to simulate a database hang scenario rather than the mouse clicks within EM12c itself.
