Description

Real Oracle database administration problems -- and real solutions.

  • Practical, accessible, hands-on guidance for every Oracle database administrator.
  • Tuning, sizing, monitoring, space management, and more.
  • Written from the ground up to cover Oracle 8i -- not a rehash of older coverage!
Oracle 8i™ Tuning and Administration: The Essential Reference is the most practical, efficient guide to Oracle 8i administration and tuning. Senior DBA Heidi Thorpe presents real-world problems, clear solutions, and the concepts behind them, giving DBAs the insights they need to understand why things work the way they do -- so they can make intelligent judgments, not simply follow "cookie-cutter" instructions. Oracle 8I™ Tuning and Administration begins with detailed solutions for day-to-day database administration: administering tables, constraints, indexes, datafiles, views, sequences, rollback segments, tablespaces, users, and more. Thorpe addresses the up-front database design issues that impact manageability and performance; offers extensive coverage of new Oracle 8i features; and reviews both database engine and application optimization in depth. The book also offers real-world insight and practical guidance for database sizing, monitoring, and space management. For all Oracle database administrators and managers responsible for supervising the day-to-day operations of Oracle databases and database-enabled Web sites.

Heidi Thorpe is Senior DBA with Texas Utilities Australia, Ltd., Melbourne, Australia. She has 14 years industry experience gained with major international companies on three continents. Thorpe holds a BSC in Chemistry from the University of Leeds, England.
