[转载] Oracle LSNRCTL------监听器的启动和关闭

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。

      本文将讨论用LSNRCTL命令启动、关闭和查看监听器的状态的方法。

怎样启动、关闭和重新启动oracle监听器

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。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

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]。

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]

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。

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.
