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. Best of all, the book is updated to
cover the very latest feature set in Oracle Database 12c.
