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:
LSNRCTL for Linux: Version 19.0.0.0.0 - Production on 01-JAN-2021 12:34:56 Copyright (c) 1991, 2019, Oracle. All rights reserved.

在这个示例中,监听器的状态为 “READY”,表示它正在运行并准备好接受连接。如果监听器的状态不是 “READY”,则需要检查 Oracle 数据库和监听器的配置,以找出问题所在。
