CHAPTER 14 Oracle Data Guard
Oracle Data Guard provides a solution for high availability, enhanced performance, and automated failover. You can use Oracle Data Guard to create and maintain multiple standby databases for a primary database. The standby databases can be started in read-only mode to support reporting users, then returned to standby mode. Changes to the primary database can be automatically relayed from the primary database to the standby databases with a guarantee of no data lost in the process. The standby database servers can be physically separate from the primary server.
In this chapter, you will see how to administer an Oracle Data Guard environment, along with sample configuration files for a Data Guard environment.
