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)
