Error ORA-12203 when trying to connect
19.04.06 at 15:18:29
 
SQL*XL user Hans from The Netherlands asked the following question.
 
Question:
This happened during logon: ORA-12203: TNS:unable to connect to destination
 
Answer:
ORA-12203: TNS: unable to connect to destination
 
You supplied an invalid TNS name (the database alias). Check the TNS name using the DOS tnsping utility. It can also be that the destination machine is not listening. Check that the listener and database server are running.
