This chapter describes the commands and associated syntax of the Listener Control utility.
This chapter contains these topics:
The Listener Control utility enables you to administer listeners.You can use its commands to perform basic management functions on one or more listeners. Additionally, you can view and change parameter settings.
The basic syntax of Listener Control utility commands is as follows:
lsnrctl command [listener_name]
where listener_name
is the name of the listener to be administered. If no name is specified, then the default name, LISTENER
, is assumed.
You can also issue Listener Control utility commands at the LSNRCTL>
program prompt. To obtain the prompt, enter lsnrctl
with no arguments at the operating system command line. When you run lsnrctl
, the program is started. You can then enter the necessary commands from the program prompt. The basic syntax of issuing commands from LSNRCTL>
program prompt is as follows:
lsnrctl LSNRCTL> command [listener_name]
Note: You can combine commands in a standard text file, and then run them as a sequence of commands. To execute in batch mode, use the format:
You can use either |
For a majority of commands, the Listener Control utility establishes an Oracle Net connection with the listener that is used to transmit the command. To initiate an Oracle Net connection to the listener, the Listener Control utility needs to obtain the protocol addresses for the named listener or a listener named LISTENER
. This is done by resolving the listener name with one of the following mechanisms:
listener.ora
file in the directory specified by the TNS_ADMIN
environment variable
listener.ora
file in the $ORACLE_HOME/network/admin
directory on UNIX operating systems and the %ORACLE_HOME
%\network\admin
directory on Windows operating systems
Naming method, for example, a tnsnames.ora
file
If the listener name is LISTENER
and it cannot be resolved, a protocol address of TCP/IP, port 1521 is assumed.
The Listener Control utility supports several types of commands:
You can use the SET command to alter parameter values for a specified listener. You set the name of the listener you want to administer with the SET CURRENT_LISTENER command. Parameter values remain in effect until the listener is shut down. If you want these settings to persist, use the SAVE_CONFIG command to save changes to the listener.ora
.
You can use the SHOW command to display the current value of a configuration setting.
The Listener Control utility can perform operations on a local or a remote listener.
To set up a computer to remotely administer a listener:
Ensure that the Listener Control utility (lsnrctl
) executable is installed.
Ensure that the name of the listener you want to administer can be resolved through a listener.ora
file or a naming method, as described in "Listener Control Utility Overview".
All commands except START can be issued when a listener is administered remotely. The Listener Control utility can only start the listener on the same computer from where the utility is running.
When issuing commands, specify the listener name as an argument. For example:
LSNRCTL> SERVICES lsnr
If the name is omitted, then listener name set with the SET CURRENT_LISTENER command is used, or the default name, LISTENER
is assumed.
It is important to provide security through a password for the listener. With a password, privileged operations, such as saving configuration changes or stopping the listener, used from the Listener Control utility will require a password.
Use the Listener Control utility's CHANGE_PASSWORD command or Oracle Net Manager to set or modify an encrypted password in the PASSWORDS_
listener_name
parameter in the listener.ora
file. If the PASSWORDS_
listener_name
parameter is set to an unencrypted password, you must manually remove it from the listener.ora
file prior to modifying it. If the unencrypted password is not removed, you will be unable to successfully set an encrypted password.
If the PASSWORDS_
listener_name
parameter is set in the listener.ora
file or the CHANGE_PASSWORD
command has been used to create a new, encrypted password, then the Listener Control utility will require a SET PASSWORD command prior to any protected command, such as STOP.
Note: If you are administering the listener remotely over an insecure network and require maximum security, configure the listener with a secure protocol address that uses the TCP/IP with SSL protocol. If the listener has multiple protocol addresses, ensure that the TCP/IP with SSL protocol address is listed first in thelistener.ora file. |
This section lists and describes the Listener Control utility commands.
Use the CHANGE_PASSWORD
command to establish an encrypted password or change an encrypted password set with the PASSWORDS_
listener_name
parameter in the listener.ora
file.
None
Yes. If a password is set, then issue then issue the SET PASSWORD command prior to this command.
From the operating system:
lsnrctl CHANGE_PASSWORD [listener_name]
From the Listener Control utility:
LSNRCTL> CHANGE_PASSWORD [listener_name]
[listener_name
]: Specify the listener name, if the default name of LISTENER
is not used.
The Listener Control utility prompts you for the old password and then for the new one. It asks you to re-enter the new one, and then changes it. Neither the old nor the new password displays during this procedure. CHANGE_PASSWORD
is usually followed by the SAVE_CONFIG command to save the new password in the listener.ora
file. If a SAVE_CONFIG
command is not issued, then the new password will be in effect only until the listener is shut down.
See Also: Oracle Net Services Administrator's Guide for further information about password security of the listener |
The following shows a new password of takd01
being set:
