Oracle SQL Tuning with Oracle SQLTXPLAIN: Oracle Database 12c Edition helps DBAs and developers work faster and more accurately, allowing complex projects to be completed within today's tighter budgets and timescales. In the past both developers and DBAs have used trial and error to solve performance problems, a slow and error-prone process which can look like groping around in the dark. Learning SQLTXPLAIN and the method in this book will turn every DBA and SQL developer into a superhero, able to solve complicated tuning problems faster than ever before, and give them the potential to save projects from expensive performance disasters. New chapters on AWR and statistics will help DBAs also avoid problems before they even begin.

Learn through this practical guide to SQL tuning how Oracle's own experts do it, using a freely downloadable tool called SQLTXPLAIN. This new edition has been expanded to include AWR, Oracle 12c Statistics, interpretation of SQL Monitor reports, Parallel execution, and Exadata-related features. Reading this book and using SQL helps you learn to tune even the most complex SQL, and you'll learn to do it quickly, without the huge learning curve usually associated with tuning as a whole.
Firmly based in real-world problems, this book helps you reclaim system resources and avoid the most common bottleneck in overall performance, badly tuned SQL. You'll learn how the optimizer works, how to take advantage of its latest features, and when it's better to turn them off.
