This manual describes all features of the Oracle database server, an object-relational
database management system. It describes how the Oracle database server
functions, and it lays a conceptual foundation for much of the practical information
contained in other manuals. Information in this manual applies to the Oracle
database server running on all operating systems.
Oracle Real Application Clusters (RAC) enables multiple instances that are linked by
an interconnect to share access to an Oracle database. This enables RAC to provide
high availability, scalability, and redundancy during failures. RAC provides scalability
without requiring application code changes.This book is intended for chief technology officers, information technology architects,
database administrators, system administrators, network administrators, and
application administrators who perform the following tasks:...
The role of Database Administrator (DBA) has become a key to success in
today’s highly complex database systems. The best DBAs work behind the
scenes, but are in the spotlight when critical issues arise. They plan, create,
and maintain databases to ensure that the databases meet the data manage-
ment needs of the business. DBAs also monitor the databases for perfor-
mance issues and work to prevent unscheduled downtime. Being an effective
DBA requires a broad understanding of the architecture of Oracle databases
and expertise in solving system-related problems.
After completing this lesson, you should be able to do
• Describe your role as a database administrator
(DBA), and explain typical tasks and tools
• Plan an Oracle database installation
• Use Optimal Flexible Architecture
• Install the Oracle software by using
Oracle Universal Installer (OUI)
Pro Oracle Database 11g RAC on Linux provides full-life-cycle guidance on implementing Oracle Real Application Clusters in a Linux environment. Real Application Clusters, commonly abbreviated as RAC, is Oracle's industry-leading architecture for scalable and fault-tolerant databases. RAC allows you to scale up and down by simply adding and subtracting inexpensive Linux servers. Redundancy provided by those multiple, inexpensive servers is the basis for the failover and other fault-tolerance features that RAC provides. ...
Whether you use this or some other DBA handbook, you will still need to refer to the Oracle database manuals frequently to get the full details of complex database operations. I can’t overemphasize the importance of mastering the fundamentals of Oracle Database 11g that are presented in the Oracle Concepts manual. Mastering this volume is critical to understanding many advanced DBA procedures.
This fully revised second edition covers the latest developments in Oracle Database 11g. Each feature is taught in a proof-by-example manner, not only discussing what it is, but also how it works, how to implement software using it, and the common pitfalls associated with it.
Client-Server Application Connection
Oracle Net enables a network connection between a client and an Oracle database server. Oracle Net is a software component that resides on both the client and on the Oracle database server. It is layered on top of the network protocol.
When a connection is initiated from a client to the Oracle database server, data is passed down a stack on the client, over the network, and up a similar stack to the Oracle database server.
Many times the Oracle DBA is hired once the database becomes to much to handle without one, inherits the position or is appointed to it “since they are so good with computers”. In any case, they usually get an undocumented system that follows no conventions and holds many traps for the unwary DBA.

This is a practical guide for developers working with the Oracle Data Provider for .NET (ODP.NET) using VB.NET. From introducing ODP.NET and programming with ODP.NET to application development using ODP.NET and on to discussing Oracle Developer Tools for Visual Studio 2005, this book covers the important aspects of ODP.NET. The book is written for professional .NET developers who need to work with and take full advantage of Oracle Database 10g using Visual Studio 2005. Developers are expected to be familiar with Visual Basic.NET 2005 and have minimum knowledge of Oracle SQL and PL/SQL....

SQL is a high abstraction level language used exclusively as an interface to Relational Databases. Initially it lacked recursion, and, therefore, had a limited expression power, but eventually this construct has been added to the language. Here we'll explore how convenient SQL is for general-purpose programming.
Oracle Database seems complex on the surface. However, its extensive feature set is really built upon upon a core infrastructure resulting from sound architectural decisions made very early on that have stood the test of time. This core infrastructure manages transactions and the ability to commit and roll back changes, protects the integrity of the database, enables backup and recovery, and allows for scalability to thousands of users all accessing the same data.
After completing this appendix, you should be able
to do the following:
Describe the Oracle Server architecture and its main components
List the structures involved in connecting a user to an Oracle instance
List the stages in processing:
As a database management system, the management of Oracle file structures is critically important to the successful operation of any system. The Oracle administrator must understand all levels of Oracle file management, including data file management principles, tablespace management principles, and the storage of individual objects within the tablespaces. As Oracle has evolved into one of the world's most complex database management systems, it is imperative that all Oracle professionals understand how their information is stored both at the logical and physical level.
This book is a quick-reference guide for Recovery Manager (RMAN), Oracle's utility to manage all of your Oracle database backup and recovery activities. This book is not a comprehensive backup and recovery book. It contains an overview of RMAN architecture, shows briefly how to backup and restore databases using RMAN, describes catalog setup issues, and provides quick-reference syntax diagrams of RMAN commands.
