$ 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
