lsnrctl
是 Oracle 数据库的一个命令行工具,用于管理和监控 Oracle 数据库的监听器。要使用 lsnrctl
查看监听器的状态,请按照以下步骤操作:
-
打开命令提示符(Windows)或终端(Linux/Unix)。
-
输入
lsnrctl status
命令,然后按 Enter 键。这将显示监听器的当前状态,包括监听器名称、版本、启动时间等信息。示例输出:

若要查看特定监听器的状态,请在
lsnrctl status
命令后添加监听器名称,然后按 Enter 键。例如:lsnrctl status my_listener
这将显示名为 “my_listener” 的监听器的状态。
注意:根据您的 Oracle 数据库版本和操作系统,lsnrctl
命令的输出可能略有不同。请根据实际情况进行调整。
