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很重要。

在启动、关闭或者重启oracle监听器之前确保使用

lsnrctl status (listener control 监听控制的简拼)

命令检查oracle监听器的状态。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

1.如果oracle监听器没用运行,你将得到如下的信息

3.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]

4.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]
[c-sharp]   view plain copy

1. $ lsnrctl stop    

2.     

3. LSNRCTL for Linux: Version 11.1.0.6.0 - Production on 04-APR-2009 16:27:37

6.     

7. Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.2)(PORT=1521)))    

8. The command completed successfully    

5.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。

[c-sharp]   view plain copy

# $ 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

nrctl 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.
