lsnrctl操作监听方法

linux命令操作监听

分类: Oracle数据库
       在linux下怎样启动、关闭和重新启动oracle监听器,对于DBA来说,启动和关闭oracle监听器是很基础的任务,但是Linux系统管理员或者程序员有时也需要在开发数据库中做一些基本的DBA操作,因此了解一些基本的管理操作对他们来说也很重要。

一、Oracle监听命令 lsnrctl 的几种用法及说明
1、lsnrctl status:检查当前监听器的状态
2、lsnrctl start [listener-name]:启动所有的监听器,可以指定名字来启动特定的监听器
3、lsnrctl stop [listener-name]:关闭所有的监听器,可以指定名字来关闭特定的监听器
4、lsnrctl reload :重启监听器,此命令可以代替lsnrctl stop,lsnrctl start
5、lsnrctl help :可以显示所有可用的监听器命令

1、Oracle监听状态查看
在启动、关闭或者重启oracle监听器之前确保使用lsnrctl status命令检查oracle监听器的状态。该命令除了得到监听器的状态之外,你还可以从lsnrctl status命令的输出中得到如下的信息:
监听器的启动时间 
监听器的运行时间 
监听器参数文件listener.ora的位置,通常位于$ORACLE_HOME/network/admin目录下 
监听器日志文件的位置 

如果oracle监听器没用运行,你将得到如下的信息
$ lsnrctl status   

LSNRCTL for Linux: Version 11.2.0.4.0 - Production on 04-APR-2009 16:27:39
Copyright (c) 1991, 2007, Oracle. All rights reserved.
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.2)(PORT=1521)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
Linux Error: 111: Connection refused

TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
Linux Error: 2: No such file or directory


如果oracle监听器正在运行,你将得到如下信息
$ lsnrctl status

2、启动oracle监听器
如果oracle监听器没用运行,你可以用lsnrctl start命令启动oracle监听器,该命令将启动所有的监听器,如果你只想启动特定的监听器,可以再start后面指定监听器的名字,例如:lsnrctl start [listener-name]。

$ lsnrctl start

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 11.2.0.4.0 - 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 11.2.0.4.0 - Production on 04-APR-2009 17:03:31

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.2)(PORT=1521)))   
The command completed successfully 

二、Oracle监听器帮助

1、查看所有的监听器命令
lsnrctl help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. 

$ lsnrctl help
