TNS-00511: No listener
Cause: The connect request could not be completed because no application is listening on the address specified, or the application is unable to service the connect request in a sufficiently timely manner.
Action: Ensure that the supplied destination address matches one of the addresses used by the listener - compare the TNSNAMES.ORA entry with appropriate LISTENER.ORA file (or TNSNAV.ORA if the connection is to go by way of an Interchange. Start the listener on the remote machine.

TNS-00511:没有侦听器,
.原因:连接请求无法完成,因为没有应用程序正在侦听指定的地址,或者应用程序无法以足够的时间方式为连接请求提供服务。,
.操作:确保提供的目标地址与侦听器使用的一个地址匹配 - 将TNSNAMES.ORA条目与适当的LISTENER.ORA文件(或TNSNAV.ORA)进行比较,如果连接将通过交换机进行通信。启动侦听器在远程机器上。,
