Error ORA-12541 when trying to connect.
26.12.05 at 15:12:20
 
Marileydy from Colombia asked the following question:
 
Question:
When I try to connecto to my Oracle database from Excel I am getting the following error code: ORA-12541  
 
Answer:
You have difficulties connecting to your database because SQL*XL cannot find your database. Perhaps the database is down or the listener is not running on the server.
 
This is what the Oracle error code means:
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.
