Oracle CFO Leaves after Four Months of Service

An anonymous reader writes "Oracle's CFO and Co-President Greg Maffei has quit. He will be succeeded by Safra Catz, who has been with Oracle for a while, and it will be interesting to see how long she lasts. Before Maffei, Harry You was CFO for 9 months, and before him was Jeff Henley. What's with the CFO shuffle at Oracle?"
