today's problem, but squarely on the problem of forecasting the future performance
of an Oracle database. Other Oracle performance books are good for putting out
fires; Craig's book helps you avoid all the heat in the first place.
Application over mathematical proofs...
If you're an IT practioner who appreciates application over mathematical proofs
than you'll be pleasantly surprised! Each chapter is filled with examples to

never been on the evening news because their company lost millions of dollars
in revenue and brand destruction because of poorly performing or unavailable
systems.
It's about equipping you…
Without a doubt you will be equipped to deal with the realities of forecasting
Oracle performance. But this book gives you more. Not only will you receive
a technical and mathematical perspective, but also a communication, a presentation,
and a management perspective. This is career building stuff and immensely satisfying!
What you'll learn

and mathematics into something you can practically apply. You will learn how
to use a variety of forecasting models, which will enable you to methodically:
* Help manage service levels from a business value perspective,
* Identify the risk of over utilized resources,
* Predict what component of an architecture is at risk,
* Predict when a system will be at risk,
* Develop multiple risk mitigating strategies to ensure service levels are
* maintained
* Characterize a complex Oracle workload.
Who is this book for?
I.T. professionals who must ensure their production Oracle systems are meeting
service levels, in part, through forecasting performance, identifying risk,
and developing solutions to ensure systems are available without wasting budget.
