ORA-12541: TNS:no listener


Cause:


The connection request could not be completed because the listener is not running.



Action:


Ensure that the supplied destination address matches one of the addresses used by the listener - compare the TNSNAMES.ORA entry with the 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.
