This Oracle-specific book begins by assuming you have already identified a particular SQL statement and are considering taking steps to improve its performance. The book describes a systematic process by which to diagnose a problem statement, identify a fix, and to implement that fix safely in a production system. You‘ll learn not only to improve performance when it is too slow, but also to stabilize performance when it is too variable. You‘ll learn about system statistics and how the Cost-Based Optimizer uses them to determine a suitable execution plan for a given statement. That knowledge provides the foundation from which to identify the root cause, and to stabilize and improve performance. .Next after identifying a problem and the underlying root cause is to put in place a solution. .Expert Oracle SQL: .Optimization, Deployment, and Statistics. explains how to apply various remedies such as changing the SQL statement, adding hints, changing the physical design, and more, and how they can be brought to bear on fixing a problem o | | 出版日期 | Book 2014 | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4302-5978-7 | | isbn_softcover | 978-1-4302-5977-0 | | isbn_ebook | 978-1-4302-5978-7 | | copyright | Tony Hasler 2014 |
