Audience

Oracle Database Performance Tuning Guide is an aid for people responsible for the operation, maintenance, and performance of Oracle Database. This book describes detailed ways to enhance Oracle database performance by writing and tuning SQL properly, using performance tools, and optimizing instance performance. It also explains how to create an initial database for good performance and includes performance-related reference information. This book could be useful for database administrators, application designers, and programmers.

For information about using Oracle Enterprise Manager to tune the performance of Oracle Database, see Oracle Database 2 Day + Performance Tuning Guide.

Documentation Accessibility

Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
