Release 2 (9.2)
Part Number A96629-01
This section describes new features of Oracle9i Data Guard broker release 2 (9.2) and provides pointers to additional information.
Oracle9i Data Guard Release 2 (9.2) provides several new features that enhance your ability to centrally control, manage, and monitor a broker configuration. In particular, release 2 introduces support for logical standby databases as well as providing significant enhancements to the existing support for physical standby databases and Data Guard broker components.
This release provides the following new features:
The Data Guard broker configures, controls, manages, and monitors a logical standby database in much the same way as is done for a physical standby database.
A supported broker configuration in release 1 (9.0.1) supported a primary site and a single physical standby site. Now, there is support for up to nine standby sites for each broker configuration. Furthermore, support includes a mix of standby databases (both physical and logical standby databases) in a single broker configuration.
The Data Guard broker makes it very easy to switchover or failover the role of the primary site and database to one of the standby sites. The new Switchover and Failover wizards in Data Guard Manager and the new
FAILOVER commands available with the Data Guard command-line interface essentially reduce these complex tasks to push-button operations.
You can dynamically tune the configuration to balance data protection levels and application performance to maximize data protection, maximize availability, or maximize performance.
