Contained in this book are, dare I say, secrets—really. There is a mystery surrounding topics like forecasting, performance management, capacity planning, performance modeling, p- formance prediction, and managing service levels. Add into the mix a dynamic Oracle system, and you have realities that bring professional capacity planners to their knees. In the pages of this book are the secrets I’ve uncovered and discovered through more than 20 years of working with literally thousands of IT professionals around the world. My goal is to expose these secrets as plainly and completely as I possibly can. One of these secrets is unraveling the relationship between service-level management and forecasting Oracle performance. The difficulty lies in the breadth and depth of each of these topics. They are both massive and fork off in a variety of directions. If you are able to bring the two together, you will be able to architect, build, use, and explain to others how they can better manage the delivery of IT services. I will, as clearly as I can throughout this book, present both these areas of IT and then weave them together. The result will leave you with a confident understanding so you can deal with the realities of IT.weiterlesen
