12 Oracle Data Guard Broker Properties

Use Oracle Data Guard broker properties to manage instances or the entire configuration.

Broker configuration and database properties help you to view and control the behavior of entire broker configurations, individual configuration members, redo transport services, and log apply services.

• Configuration Properties

• Monitorable (Read-Only) Properties

• Configurable Properties

Properties have either configuration-wide scope, database-wide scope, far sync instance-wide scope, or instance-specific scope. Configuration-wide properties control the behavior of the broker on all members of the configuration. The values of such properties apply uniformly across all members of the configuration.

Database-wide properties allow you to view or control the behavior of a specific database. If the database (primary or standby) is an Oracle RAC database consisting of multiple instances, then the value of such a property applies uniformly across all instances of that database.

Far sync instance-wide properties allow you to view or control the behavior of a far sync instance.

Instance-specific properties allow you to view or control the behavior of an individual database instance. Such a property exists for all instances of an Oracle RAC database, but its value can differ from one specific instance to another.

Note:

You can use the Oracle Data Guard broker command-line interface (DGMGRL) to view or modify broker properties.

Oracle Enterprise Manager Cloud Control (Cloud Control) explicitly presents some broker properties on the Edit Properties page. Information from other properties can be implicitly incorporated into other Web pages displayed by Cloud Control. See the individual description of each property for information about how Cloud Control presents that property.
