Well, I suppose this may be a little controversial, but we used auto memory management and came to conclusion it is a major source of some of our problems.
The idea is fine and we suppose it works great for instances with less turbulent memory structure changes
However since we started with ASMM, we experienced several major server failures, while working with static settings it was not the case. Of course now we have to bounce server to change settings, but still it is better to have a control over shutdown process.
