Overview

Troubleshooting Oracle Performance, 2nd Edition is your systematic guide to diagnosing and resolving performance problems in database-backed applications involving Oracle's database engine. Christian Antognini brings a decade and a half experience to his topic. His first edition is one of the most well-respected books in its field. This second edition has been rigorously updated to cover the latest developments in Oracle Database 11g Release 2 through Oracle Database 12c.

What do you do when your database application isn’t running fast enough? You troubleshoot, of course. Finding the slow part of an application is often the easy part of the battle. It’s finding a solution that’s difficult. Troubleshooting Oracle Performance, 2nd Edition helps by providing a systematic approach to addressing the underlying causes of poor database application performance. The author freely shares his experience while explaining the underlying foundations of how SQL statements are executed by the Oracle database engine. You'll be able to draw a solid foundation of theory and shared experience as you face head-on the performance challenges in your daily work.

  • Written for developers by an application developer who has learned by doing
  • Gives a systematic approach to solving database application performance problems
  • Helps you plan for performance as you would for any other application requirement

What you’ll learn

  • Systematically identify performance problems
  • Configure the query optimizer to meet performance goals
  • Read and recognize inefficient execution plans
  • Minimize the impact of parsing upon performance
  • Optimize data access, joins, and the physical design of your database
  • Improve performance through parallel processing, materialized views, and result caching
  • Apply SQL tuning techniques such as hints, SQL profiles, stored outlines, and SQL plan baselines
  • Reduce inefficiencies from too much procedural code

    Great book on Oracle Troubleshooting for any level!

    The author Christian Antognini has done a wonderful job in writing a great book on how to systematically analyze issues with Oracle 11g. Let's be honest, Oracle 11g is a beast and take a very long time to master all areas of its core functionality. I have been using Oracle for only a few years and I sometime still consider myself a newbie.

    The recent version of 11g has added lots of new functionality such as database replay, sql access advisor, sucurefiles, flashback data archiving, tablespace encryption, data masking and so much more. IT sometimes feels that version 11g is a totally new database compared to version 10.x.

    The great thing about this book which others fail is that it covers all versions of Oracle from version 9i to 11gR1. So even if you are using an older version this book still is extremely valuable to own. It will actually save you money if you are using an older version of Oracle because it can be used as you gradually upgrade to newer versions of Oracle. Another reason to buy it!

    This book assumes that you already have a good knowledge of using Oracle and goes right into many different scenarios of using different front-end technologies where performance issues can happen and hot to step-by-step figure out where your problem may be coming from.

    The author focuses on tracing database calls, profiling PL/SQL code, how to review workload statistics and object statistics, how to configure your query optimizer, and one of the most useful sections of the book is Chapter 6 where the author focus on many different execution plans. I also liked Chapter 10 where the author goes through all the different types of SQL commands (joins, nested loops, merge joins, hash joins, etc.) and how they can be improved and optimized.

    For the size of the book (500+), the author really gives you some great material that can be used for many years of using Oracle. It can be used for the beginner Oracle user (after they get their feet wet) for understanding how to write SQL the optimized way, for the Application Oracle developer and for the DBA as well.

    I cant see how this book cannot be in your library. A must buy!
