Oracle 11g continues the tradition of feature enhancement
by making memory management more automated, adding several new advisors,
and significantly improving availability and failover capabilities. Part I of this book
covers the basics of the Oracle architecture and lays the foundation for deploying a successful
Oracle infrastructure by giving practical advice for a new installation or upgrading from a previous
release of Oracle. To provide a good foundation for the Oracle 11g software, we cover server
hardware and operating system configuration issues in the relevant sections.
In Part II of this book, we will cover several areas relevant to the day-to-day maintenance and
operation of an Oracle 11g database. The first chapter in Part II discusses the requirements that a
DBA needs to gather long before you mount the install CD on your server. Successive chapters deal
with ways the DBA can manage disk space, CPU usage, and adjust Oracle parameters to optimize
the server??™s resources, using a variety of tools at the DBA??™s disposal for monitoring database
performance. Transaction management is greatly simplified by Automated Undo Management
(AUM), an Oracle Database feature introduced in Oracle9i and enhanced in Oracle 10g and
Oracle 11g.
Part III of this book focuses on the high availability aspects of Oracle 11g. This includes using
Oracle??™s Recovery Manager (RMAN) to perform and automate database backups and recovery,
along with other features, such as Oracle Data Guard, to provide a reliable and easy way to
recover from a database failure.
