查看Oracle数据库监听是否启动应使用lsnrctl命令,命令如下
$ lsnrctl status

lsnrctl命令常用参数:
$ lsnrctl status:检查当前监听器的状态
$ 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
$ 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
$ lsnrctl reload 重启监听器,此命令可以代替lsnrctl stop,lsnrctl start
$ lsnrctl help 可以显示所有可用的监听器命令
以 ORACLE为例 ps -ef | grep ora 如果有多个 以 ORA开头的进程,那 就说明数据库启动了 lsnrctl status 看返回如果有 多个记录行,说明监听已经启动 su - oracle sqlplus /nolog conn / as sysdba startup 返回带有running的,说明数据库也已经...
