Data Guard is the high availability, disaster recovery and data replication solution for Oracle Databases.
With the huge growth of Data Guard it’s getting harder to encounter an Oracle DBA not dealing with Data Guard. Since it’s a common DBA task to provide high availability of databases, Data Guard is a must-know topic for every Oracle Database Administrator.
“Oracle Data Guard 11g R2 Beginner’s Administration Guide” is a practical guide that provides all the information you will need to configure and maintain Data Guard. This book will show you what Data Guard can really do.
By following the practical examples in this book, you’ll learn to set up your Data Guard Broker, the management framework for Data Guard configurations. Learn and implement different data protection modes, perform role transitions between databases (switchover and failover) and configure Active Data Guard. Next, we will dive into the features of Snapshot Standby. The book progresses into looking at Data Guard configuration with other Oracle products (such as EM, RAC, and RMAN) and patch databases in Data Guard. The final chapters will cover commonly encountered Data Guard issues and Data Guard best practices, which are very important to make a Data Guard configuration perfect and take maximum advantage of Data Guard properties.
