前几天一台项目开发使用的Oracle11g服务器重启系统之后,出现了几个莫名的报错,下面是其中一个,已解决。
$ lsnrctl start报错提示:
The listener supports no servicesThe command completed successfully: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 标签:no,listener,orcl,报错,SID,supports From: https://www.cnblogs.com/dabao150114/p/16719787.html
