" Geoff Ingram has met the challenge of presenting the complex process of managing Oracle performance. This book can support every technical person looking to resolve Oracle8i and Oracle9iperformance issues." – Aki Ratner, President, Precise Software Solutions 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 hands-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 book provides practical solutions for: Choosing physical layout for ease of administration and efficient use of space Managing indexes, including detecting unused indexes and automating rebuildsSQL and system tuning using the powerful new features in Oracle9i Release 2Improving SQL performance without modifying codeRunning Oracle Real Application Clusters (RAC) for performance and availabilityProtecting data using Recover Manager (RMAN), and physical and logical standby databases Thecompanion Web site provides the complete source code for examples in the book, updates on techniques, and additional documentation for optimizing your Oracle system.

Net8 is the fundamental Oracle technology that allows Oracle services and clients to communicate with each other over a network. Net8 is most often used to connect client software to Oracle database servers. It may also be used to connect database servers to one another, allowing communication between distributed databases. This practical guide provides the information that readers, especially database administrators, need to know in order to install configure, tune, and troubleshoot Net8. It discusses how Oracle's network architecture, products, and name resolution methods work, and it provides the details of client and server configuration using a variety of Oracle protocols and networking products, including: The Oracle Internet Directory (OID), Oracle's implementation of the standard Lightweight Directory Access Protocol (LDAP). This directory can be used to maintain a central repository of net service names that can be referenced by all clients. Oracle Names, a networking component used mainly in earlier versions of Oracle, that allows net service names to be defined centrally. Multi-Threaded Server (MTS), an environment in which the client connections share access to a pool of shared server processes. Oracle Connection Manager, a Net8 component that acts much like a router and provides protocol conversion, connection concentration, and access control. The book also describes the utilities Oracle provides to help manage a Net8 environment; these include the Listener Control Utility (Isnrctl), the Oracle Names Control Utility (namesctl), the Oracle Connection Manager Control Utility (cmctl), tnsping, and Net8 Assistant. In addition, it provides a variety of networkingtroubleshooting techniques and commonly encountered Net8 configuration problems, and provides complete syntax for all networking files and commands.
