Property Description
Parameter type Boolean
Default value False unless multithreaded Oracle is enabledFoot 1 
Range of values true | false
Basic No
Oracle RAC If specified, all instances must use the same value

Footnote 1 Multithreaded Oracle is enabled by setting the THREADED_EXECUTION initialization parameter to true.

USE_DEDICATED_BROKER determines how dedicated servers are spawned. When this parameter is set to false, the listener spawns a dedicated server directly.

When this parameter is set to true, the listener hands the connection to a dedicated connection broker that spawns the dedicated server. Unlike the listener, the dedicated connection broker is a database process, and hence it can implement policies leveraging database information before the spawn.

To enable the dedicated connection broker using the USE_DEDICATED_BROKER initialization parameter, you must:

  1. Set the USE_DEDICATED_BROKER initialization parameter to true.

  2. Set the DEDICATED_THROUGH_BROKER_listener-name parameter to on in the listener.ora file.


When multithreaded Oracle is enabled, the dedicated connection broker process is also enabled and used.

Configuration of the brokers is controlled by the CONNECTION_BROKERS initialization parameter.
