The books in O'Reilly's Oracle series are authoritative -- they tell the whole story about complex topics, ranging from performance tuning to the use of packages in PL/SQL to new technologies like Power Objects. And they're independent; they're alternatives for readers who need to know how products and features really work. They're packed with real-world advice and techniques from practitioners in the field, and they come with disks containing code you can use immediately in your own applications. O'Reilly is the alternative for Oracle people who need to solve problems -- and solve them now. Performance tuning is crucial in any modern relational database management system. Too many organizations respond to Oracle performance problems by throwing money at these problems -- by buying larger and more expensive computers or by hiring expert consultants. But there's a lot you can do on your own to increase dramatically the performance of your existing system. Whatever version of Oracle you're running -- from Version 6 to Oracle8, proper tuning can save your organization a huge amount of money in additional equipment, extra memory, and hardware upgrades. The first edition of Oracle Performance Tuning has become a classic for programmers, managers, database administrators, system administrators, and anyone who cares about improving the performance of an Oracle system. This second edition is a complete rewrite; it adds 400 pages to the first edition, updating all the original information, incorporating new advice about disk striping and mirroring, RAID, client-server, distributed databases, MPPS, SMPs, and other architectures. It also includes new chapters on parallel server, parallel query, backup and recovery, the Oracle Performance Pack, and more.
