The purpose of this book is to help organizations deploy Oracle8i and Oracle9i (including Release 2) systems that meet the key end-user requirements of performance and availability at the same time. The ability to deliver on these twin requirements requires a holistic approach to the design and build of the end-to-end Oracle system, and this holistic approach is at the heart of this book. Too often, insufficient emphasis is given to components that are not related to the server. For example, consider a scenario where an Oracle end-user application uses a local configuration file (tnsnames.ora) to locate an Oracle database.If the database relocates to a new server one weekend, and the configuration file change is overlooked, end users won’t be able to connect on Monday morning. The database may as well be down. From the end-user perspective, it is. In the worst case, the outage could affect the organization’s bottom line. Appropriate network configuration, based on a centralized naming service, is a critical success factor for delivering availability. A similar emphasis is required on all aspects of the Oracle configuration, from initial installation to production support, in order to meet performance and availability requirements.This book is divided into six parts, which are intended to cover subjects in the order you might address them when setting up an Oracle configuration from scratch. In order to get the most out of the book, the best approach is to read it from cover to cover in sequential order. The detail is important, and a lack of attention to detail in all relevant areas of the technology is based on personal experience significant reason why Oracle systems don’t meet end-user performance and availability requirements.This book is intended for both DBAs and developers of all levels. In many ways, the term advanced in the Oracle world is something of a misnomer. The scope of what Oracle provides is very extensive: There’s a lot to know, but most of it is not especially complex. Anyone who understands Oracle fundamentals can understand and benefit from the contents of this book and Oracle’s own Concepts Guide is a great place to start. The challenge comes in deploying systems based on techniques that work from the many techniques available. This book sets out to provide a fast track to deploying systems with performance and availability built in.
