3.关闭oracle监听器
如果oracle监听器正在运行，可以使用lsnrctl stop命令关闭oracle监听器，该命令将关闭所有的监听器，如果你只想关闭特定的监听器，可以再stop后面指定监听器的名字，例如：lsnrctl stop [listener-name]
$ lsnrctl stop LSNRCTL for Linux: Version 11.1.0.6.0 - Production on 04-APR-2009 16:27:37 Copyright (c) 1991, 2007, Oracle. All rights reserved. Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.2)(PORT=1521))) The command completed successfully $ lsnrctl stop LSNRCTL for Linux: Version 11.1.0.6.0 - Production on 04-APR-2009 16:27:37 Copyright (c) 1991, 2007, Oracle. All rights reserved. Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.2)(PORT=1521))) The command completed successfully
4.重启oracle监听器
用lsnrctl reload重启监听器，此命令可以代替lsnrctl stop和lsnrctl start。重启将会在不需要关闭和启动监听器的情况下读取listener.ora的配置。
$ lsnrctl reload LSNRCTL for Linux: Version 11.1.0.6.0 - Production on 04-APR-2009 17:03:31 Copyright (c) 1991, 2007, Oracle. All rights reserved. Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.2)(PORT=1521))) The command completed successfully $ lsnrctl reload LSNRCTL for Linux: Version 11.1.0.6.0 - Production on 04-APR-2009 17:03:31 Copyright (c) 1991, 2007, Oracle. All rights reserved. Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.2)(PORT=1521))) The command completed successfully
Oracle监听器帮助
1.查看所有的监听器命令
lsnrctl hep命令可以显示所有可用的监听器命令。在oracle11g中其输出如下：
start - Start the Oracle listener
stop - Stop the Oracle listener
status - Display the current status of the Oracle listener
services - Retrieve the listener services information
version - Display the oracle listener version information
reload - This will reload the oracle listener SID and parameter files. This is equivalent to lsnrctl stop and lsnrctl start.
save_config - This will save the current settings to the listener.ora file and also take a backup of the listener.ora file before overwriting it. If there are no changes, it will display the message “No changes to save for LISTENER”
trace - Enable the tracing at the listener level. The available options are ‘trace OFF’, ‘trace USER’, ‘trace ADMIN’ or ‘trace SUPPORT’
spawn - Spawns a new with the program with the spawn_alias mentioned in the listener.ora file
change_password - Set the new password to the oracle listener (or) change the existing listener password.
show - Display log files and other relevant listener information.
