Hi list, recently I had a problem with a customer, we solved the problem but the situation was really strange, it seemd to be something in the hardware. Some week ago I went to his office and discovered they had a problem with aeration, the room where is the computer was extremely hot. The point is, if there is some trick to know if there is a problem cause by exposing the server to overheating for some periods, from Oracle database. I don't think there is, but I ask anyway.
