Examples abound in database applications of well-formulated queries running slowly, even if all levels of the database are properly tuned. It is essential to address each level separately by focusing first on underlying principles and root causes, and only then proposing both theoretical and practical solutions. "Database Performance Tuning and Optimization" provides comprehensive coverage of database performance tuning using Oracle 8i and select 9i examples as the RDBMS. The coverage contains b oth theoretical discussions dealing with principles and methodology as well as actual SQL scripts to implement the methods. The book combines theory with practical tools (in the form of Oracle and Unix shell scripts) to address the tuning and optimization issues of DBAs and developers, irrespective of whether they use Oracle. Readers not using Oracle can implement the essential principles via scripts of their own written for the RDBMS used by them.

From the exclusive publishers of Oracle Press books comes a unique volume, packed with undocumented tips & techniques, for tuning and tailoring Oracle9i to perform at its peak. Author Rich Niemiec has been named by Oracle Corporation as one of the top six Oracle experts in the world!

Ensuring high-performance and continuous availability of Oracle software is a key focus of database managers. At least a dozen books address the subject of "performance tuning"–– that is, how to fine-tune the Oracle database for its greatest processing efficiency. Geoff Ingram argues that this approach simply isn’t enough. He believes that performance needs to be addressed right from the design stage, and it needs to cover the entire system––not just the database. High-Performance Oracle is a h ands-on book, loaded with tips and techniques for ensuring that the entire Oracle database system runs efficiently and doesn’t break down. Written for Oracle developers and DBAs, and covering both Oracle8i and Oracle9i, the book goes beyond traditional performance-tuning books and covers the key techniques for ensuring 24/7 performance and availability of the complete Oracle system.

The latest version of this popular guide introduces the fundamental commands and techniques used in Oracle 9i database systems, and how to develop applications using Oracle and SQL.

The purpose of this book is to share my experiences in the areas of UNIX and Oracle performance and tuning. The chapters of this book provide a tremendous level of detail on the internal workings of the Oracle and UNIX kernels. The purpose of including so much detail is to give the reader a complete understanding of Oracle and UNIX. It is this understanding that will enable the reader to apply these concepts to specific applications and/or user environments, thus enabling the reader to maximize the performance of his or her environment. It is a key characteristic of this book that only the latest versions of Oracle and UNIX are discussed, such as Oracle8i and Solaris 8. This will enable the reader to focus on the functionality and enhancements of the new versions, avoiding discussion of old releases. Another characteristic of this book is that I have organized it into two major areas: data warehousing and Online Transaction Processing (OLTP). This edition of the book places more of an emphasis on application tuning since the application has the most control over the overall performance and scalability. It is important that the application be well designed and highly optimized. Recommended prerequisites for this book are a basic understanding of SQL, UNIX shell language, and experience with UNIX system and Oracle database administration.

Advanced performance tuning with Oracle involves unraveling the mysteries of the SQL database's inner workings. Oracle8i Internal Services for Waits, Latches, Locks, and Memory peels back several layers of the Oracle onion to reveal how things really work. While the author claims his quest to get to the bottom of Oracle still continues, this book is a snapshot of his current knowledge of the performance-critical internals. The book's title tells the whole story about its content. It focuses on waits, latches, locks, and memory allocation because they have a dramatic effect on overall performance. Each of these topics is presented separately, with explanations of how each works under the hood and what can be done to optimize it. Although the title offers plenty of architectural explanation, a solid foundation into Oracle 8i release 8.1 (the version addressed by the author) is a prerequisite for understanding this text. The presentation includes few diagrams. Instead, the author makes a special effort to list relevant Oracle parameters and their descriptions in tables, as well as examples of statistics that can be used in optimization. This is a guide for advanced administrators already on a solid footing with Oracle8i and offers plenty of insight into the crucial undocumented aspects of the relational database.
