Differences between the First and the Second Edition of Troubleshooting Oracle Performance

Several people asked me how much I changed in the second edition. The short answer is… A LOT.

The main goals set for the revision of the book were the following:

  • Add content about Oracle Database 11g Release 2 and Oracle Database 12c Release 1.
  • Remove content about Oracle9i and Oracle Database 10g Release 1.
  • Add content that was “missing” in the first edition (for example, features like hierarchical profiler, active session history, AWR and Statspack).
  • Add information about PHP in the parts that cover features that are specific to programming languages.
  • Reorganize part of the material for better readability. For example, splitting the chapter about system and object statistics in two.
  • Fix errata and generally enhance the text.

To provide you a visual picture about the changes, with Word I did a diff on the text before and after the editing. Here are the resulting pictures… (note that changes are in red and movements are in green)

    This 2nd edition (even though alpha version) has still been stunning, and made me learn new things :)

    Since I have been one of the Technical Reviewers, I am definitely aware that the second edition contains a wealth of new information, and a lot of big improvements and updates of the “old” material – I have actually really enjoyed reading the book for this very reason. And I experienced first-hand the really hard work that has been necessary to write this book, especially since Chris wanted to keep the quality very high …
    It is anyway stunning to see all those changes summarized “in pictures” :O

    Your presentation in Paris for Paris Oracle Meetup ( thanks to Gregory ) was very impressive.

    I look forward to read the second version of your book ( the first was very interesting ).
