Characteristics of the Listener Process The database server receives an initial connection from a client application through the listener. The listener is a process running on a node that listens for incoming connections on behalf of a database or a number of databases. The following are the characteristics of a listener: A listener process can listen for more than one database Multiple listeners can listen on behalf of a single database to perform load balancing The listener can listen for multiple protocols The default name of the listener in Oracle Net is LISTENER The name of the listener must be unique per file Note: Oracle9i databases require. | Basic Oracle Net Server Side Configuration Objectives After completing this lesson, you should be able to do the following: Identify how the listener responds to incoming connections Describe Dynamic Service Registration Configure the listener by using Oracle Net Manager Control the listener by using the Listener Control Utility Configure the listener for HTTP connections The Listener Process Listener Client Server Characteristics of the Listener Process The database server receives an initial connection from a client application through the listener.

Earlier versions of the listener are not supported. However, it is possible to use an Oracle9i listener with databases created with an earlier version of Oracle. Using Oracle Enterprise Manager The Listeners page under the Nodes folder in the Navigator displays listener properties for a node selected in the Navigator. Information displayed includes a list of all databases monitored by the listener as well as the TNS address of the listener. You can determine the operational status of the listener by clicking Listener Status. Connection Methods When a connection request is made by a client to a server, the listener performs one of the following: Spawns a server process and bequeaths (passes) the connection to it Hands off the connection to a dispatcher in an Oracle Shared Server configuration Redirects the connection to a dispatcher or .
