谁能告诉我数据库连接的时候报ora-12541是什么错误?
我在用DBA STUDIO连接数据库的时候报ora-12541 没有监听器。但我的配置文件(listener,ora,tnsname.ora检查过,均无问题,用lsnrctl也报告成功,不知是何原因连接不上?(注:我的服务器与客户机在一台机器上,应该没问题呀!)
To correct this problem, follow these steps:
1.Stop the listener.
2.Reconfigure QUEUESIZE in your listener (LISTENER.ORA) configuration file to be a larger value (based on anticipated simultaneous connect requests).
3.Restart the listener.
4.Try to connect again.
