$ lsnrctl start
报错提示:
The listener supports no services The command completed successfully 如图所示:
这样启动后远程连接会报错: oracle ORA-12514:TNS:listener does not currently know of service requested in connect descriptor
问题原因:数据库实例没注册到listener
解决方法一: 在listener.ora里面添加了一行
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC = (GLOBAL_DBNAME = orcl)
(SID_NAME = orcl) ) )
注:里面的orcl根据你安装的数据库实例名确定,我用此法解决了这个报错。
解决方法二: 登录数据库:
$sqlplus / as sysdba
显示服务名:
SQL>show parameter service_names
强制注册服务:
SQL>alter system register;
查看监听状态: $lsnrctl status
