I'm trying to log in to BrioQuery, or to another application that requires Oracle and am getting the error message:
How can I resolve this?
An ORA-12541 error occurs when the listener for the destination server is down or unreachable. This can be due to the listener not being started or being incorrectly configured, or it can be due to a network connection problem.
Two likely reasons for the error:
- the database was briefly unavailable at the time when you tried to access.
- the Oracle client application on your machine is not configured correctly. See: "TNS could not resolve connect identifier specified", "...could not resolve service name"
