I maintain a high volume DB2 shop. The formulas I found in this book for determining system usage for implementing new user apps, utilizing DB2 Estimator, Optimizer and DB2 PM has made my work easier to monitor and maintain. The formulas for system capacity, usage, and thruput work. I really didn't think they would but they do. I don't need IBM manuals, I need more books like this one.
