This is just like a firefighter knowing how to listen to Oracle, through Oracle's wait interface. This book will teach you how to listen to Oracle. But this is just the start. * Second, even with an amazing diagnosis, to solve John's problem, the doctor must have a deep understanding of the human body and specifically in this case, the elbow. This is just like a performance specialist knowing Oracle internals. Knowing Oracle is suffering from intense library cache contention is good, but to solve the problem, you must understand Oracle internals enough to influence the situation to reduce the contention. * Finally, the doctor has been practicing11 for a number of years. This adds confidence and a broader experience.
