What causes Oracle err 3121 "no interface driver connected "
What is Oracle error 3121 "No interface driver connected"?
The Oracle 3121 error message may occur if you are trying to
connect Progress to Oracle via SQL*Net and you are not
providing the SID on the connection.
For example, you may connect via SQL*net with the following
connection parameters:
-U userid@oracle_sid -P password
Please note that anytime you provide the username it must be
followed by the @ and the oracle_sid in order for the SQL*Net
connection to work.
The 3121 has occurred in cases where the user typed in the
correct -U and -P (shown above) but then was prompted for
username and password redundantly. The user filled in
the username again without the SID
and this overrode the original connection parms.
This caused the sql*net connection to fail with the 3121 error.
