Description

This small book is an indispensable guide for using Oracle for a disaster recovery strategy. Covering all areas of disaster recovery, standby database and automatic Oracle failover, this book explains the use of Oracle10g Data Guard solution provides a comprehensive Solution for disaster recovery. This book covers all aspects of Oracle Data Guard in detail and provides an overview of the latest Data Guard features in Oracle10g.

Written by a working Oracle DBA, this text covers the concepts and the architecture of standby databases and provides a detailed description of the implementation and management of data guard. Expert tips are revealed for success in configuration and first-time implementation of Data Guard. Advance topics such as "Using RMAN to create Data Guard Configuration" and "Data Guard Broker" have been discussed in detail to assist production DBAs managing multiple databases.
