The local listener, or default listener, is located in the Grid home when you have Oracle Grid Infrastructure installed. The
listener.ora file is located in the
If needed, you can edit the
listener.ora file for the Grid home listeners to define listener parameters for node and SCAN listeners. Do not modify the endpoints because these are automatically managed by the listener agent.
During Oracle Database creation, the
LOCAL_LISTENER parameter is automatically configured to point to the local listener for the database. You can set a value manually for
LOCAL_LISTENER. If you modify the value of the
LOCAL_LISTENER parameter, then the Database Agent process does not automatically update this value. Oracle recommends that you leave the parameter unset so that the Database Agent process can maintain it automatically. If you do not set
LOCAL_LISTENER, then the Database Agent process automatically updates the database associated with the local listener in the Grid home, even when the ports or IP address of that listener are changed.
