Hi all, I've been asked by our VP to give estimation what is consider heavy system OLTP in term of redo per bytes rate. She told to to test our exadata machine with load of 80Mb per second per Node , and I've told her that I think it is too much . if OLTP system with generate 80Mb* (2 nodes) per second that it means 576G per hour . I wonder if anyone work with such systems , what is the typical redo rate ? thanks amihay
