Oracle Solution for Error ora-12541
What triggered the Error:
The connection request could not be completed because the listener is not running.What should we do to fix it:
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.
