描述.Throughout history, advances in technology have come in spurts. A single great idea can often spur rapid change as the idea takes hold and is propagated, often in totally unexpected directions. Exadata embodies such a change in how we think about and manage relational databases. The key change lies in the concept of offloading SQL processing to the storage layer. That concept is a huge win, and its implementation in the form of Exadata is truly a game changer. .Expert Oracle Exadata. will give you a look under the covers at how the combination of hardware and software that comprise Exadata actually work. Authors .Kerry Osborne., .Randy Johnson., and .Tanel Põder. share their real-world experience, gained through multiple Exadata implementations with the goal of opening up the internals of the Exadata platform. This book is intended for readers who want to understand what makes the platform tick and for whom—"how" it does what it is does is as important as what it does. By being exposed to the features that are unique to Exadata, you will gain an understanding of the mechanics that will allow you to fully benefit from the advantages that the platform provides..Changes the way you t

Offloading / Smart Scan,oncept of moving processing from the database servers to the storage layer. It is also the key paradigm shift provided by the Exadata platform.

Exadata Parallel Operations,ng is a key component of Exadata because efficient handling of Data Warehouse workloads was a primary design goal for Exadata. In addition, because Offloading/Smart Scan depends on direct path reads, which are used by parallel query slaves, parallel operations take on a whole new importance. Traditi

Recovering Exadata,system, your disk drives begin aging. Disk drives have come a long way in the past 30 years, and typical life expectancy has improved dramatically. At the end of the day, though, it’s a matter of “when” a disk will fail, not “if.” And we all know that many disk drives fail long before they should. K
