Expert Oracle SQL: Optimization, Deployment, and Statistics EPUB
is about optimizing individual SQL statements, especially on production database systems. 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. 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 once and for all. Rolling a change out smoothly is an important topic when dealing with tuning and optimization. does not let you down in this critical area. The book contains two chapters of good information from an experienced professional on how to safely deploy changes into production so that your systems remaining running and available throughout the deployment process. Describes a systematic approach to tuning Oracle SQL Explains how things are supposed to work, what can go wrong, and how to fix it Takes you through the steps needed to stabilize performance in your production systems What you'll learn Determine the root cause of poor performance in a SQL statement Decipher each line of an execution plan and how it relates to its source SQL statement Know the various options and transformations available for the Cost-Based Optimizer Interpret the diagnostic data from Active Session History, SQL Performance Monitor, and from other sources Apply optimizer hints, SQL profiles, and SQL baselines when they are best used, and avoid them otherwise Manage object statistics used by the optimizer to ensure efficient execution plans Who this book is for is aimed at Oracle Database administrators who are interested in performance troubleshooting. The book is also of interest to people in development roles who wish to be knowledgeable in the underlying technologies on which their applications run. Table of Contents PART I: Basic Concepts1.

Expert Oracle RAC Performance Diagnostics and Tuning EPUB
provides comprehensive coverage of the features, technology and principles for testing and tuning RAC databases. The book takes a deep look at optimizing RAC databases by following a methodical approach based on scientific analysis rather than using a speculative approach, twisting and turning knobs and gambling on the system.

The book starts with the basic concepts of tuning methodology, capacity planning, and architecture. Author Murali Vallath then dissects the various tiers of the testing implementation, including the operating system, the network, the application, the storage, the instance, the database, and the grid infrastructure. He also introduces tools for performance optimization and thoroughly covers each aspect of the tuning process, using many real-world examples, analyses, and solutions from the field that provide you with a solid, practical, and replicable approach to tuning a RAC environment. The book concludes with troubleshooting guidance and quick reference of all the scripts used in the book.
