有时候就报这个错误请问这到底是怎么回事啊?
of service requested in connect descriptor监听器不认识你所要访问的网络服务名。
这个网络服务名称应在tnsnames.ora文件中配置。
1 Wait a moment and try to connect a second time. 2 Check which services are currently known by the listener by executing: lsnrctl services <listener name> 3 Check that the SERVICE_NAME parameter in the connect descriptor of the net service name used specifies a service known by the listener. 4 If an easy connect naming connect identifier was used, check that the service name specified is a service known by the listener. 5 Check for an event in the listener.log file.
