  • This book is about tuning Oracle databases. Three areas of Oracle Database tuning are data model tuning, SQL code tuning, and physical and configuration tuning. The author began his career as an applications developer, not as a systems or network administrator. As a result, this book is written from an applications rather than an operating system perspective.

  • You can enhance Oracle performance by adjusting database applications, the database itself, and the operating system. Making such adjustments is known as tuning. Proper tuning of Oracle provides the best possible database performance for your specific application and hardware configuration. Note: Oracle8 Tuning contains information that describes the features and functionality of the Oracle8 and the Oracle8 Enterprise Edition products. Oracle8 and Oracle8 Enterprise Edition have the same basic features.

  • Tuning of SQL code is generally cheaper than changing the data model. Physical and configuration tuning involves a search for bottlenecks that often points to SQL code or data model issues. Building an appropriate data model and writing properly performing SQL code can give 100%+ performance improvement. Physical and configuration tuning often gives at most a 25% performance increase.

  • This book is a quick-reference guide for tuning Oracle SQL. This is not a comprehensive Oracle tuning book. The purpose of this book is to give you some light reading material on my "real world" tuning experiences and those of my company, Mark Gurry & Associates. We tune many large Oracle sites. Many of those sites, such as banks, large financial institutions, stock exchanges, and electricity markets, are incredibly sensitive to poor performance. With more and more emphasis being placed on 24/7 operation, the pressure to make SQL perform in production becomes even more critical.

  • Many machine translation (MT) evaluation metrics have been shown to correlate better with human judgment than BLEU. In principle, tuning on these metrics should yield better systems than tuning on BLEU. However, due to issues such as speed, requirements for linguistic resources, and optimization difficulty, they have not been widely adopted for tuning.
