How to configure listener in Oracle Net Manager?
On the host where the local listener resides, configure the listener.ora file with the protocol address of the listener using Oracle Net Manager. On the database, set the LOCAL_LISTENER parameter in the database initialization parameter file to the alias of the local listener. For example:
Which is the old host name for Oracle?
I can see that it is using the old host name, but I don’t know where it is pulling that value from. My Oracle installation is 11.2.0 on Windows7 x64, if that makes any difference. When you run lsnrctl status, one of the things that it tells you is the location of the Listener Parameter File (the listener.ora file)
Is the Oracle Database listener no longer supported?
In Oracle Database 12 c release 2 (12.2), the listener password feature is no longer supported. This does not cause a loss of security because authentication is enforced through local operating system authentication. Refer to Oracle Database Net Services Reference for additional information.
Can a listener be started with no configuration?
Because the configuration parameters have default values, it is possible to start and use a listener with no configuration. This default listener has a name of LISTENER, supports no services on startup, and listens on the following TCP/IP protocol address: The listener forwards client requests to supported services.
To configure protocol addresses for the listener using Oracle Net Manager, do the following: Start Oracle Net Manager. In the navigator pane, expand Local, and then select Listeners. Select the listener. From the list in the right pane, select Listener Locations. Select the protocol from the Protocol list.
Do you need to change the listener in Ora?
You dont need to change the listener.ora. After you create/start the service, the database will register that service with the listener (and will do so periodically). Or you can issue “alter system register”. In particular, the SID name is *not* related to the service.
Is it possible to run more than one listener in Oracle?
Multiple listener configurations are possible because each of the top-level configuration parameters has a suffix of the listener name or is the listener name itself. It is often useful to configure multiple listeners in one listener.ora file. However, Oracle recommends running only one listener for each node in most customer environments.
Because all of the configuration parameters have default values, it is possible to start and use a listener with no configuration. This default listener has a name of LISTENER, supports no services on startup, and listens on the following TCP/IP protocol address: The listener forwards client requests to supported services.
What should host entry be in listener.ora file?
The HOST entry in the “listener.ora” file must point to an active network adapter, either real or loopback. If not, the listener will fail to start. If the HOST entry in the “listener.ora” file is set to “localhost”, the listener will start and accept connections from the local server, but not from other clients.
How to resolve Oracle Net listener name alias?
Resolve the listener name alias for the LOCAL_LISTENER setting through a tnsnames.ora file on the database host using a text editor, as follows: If you are registering a local listener and use Oracle Connection Manager, then do not include (DESCRIPTION = or its closing parenthesis.
