Unable to connect to database from windows command prompt

user9103174Mar 4 2013 — edited Mar 5 2013
Hi All,
Im trying to connect to Oracle database from my windows command prompt, these are the steps I followed:

1) cd C:\oracle\product\11.2.0\client_1\sqlplus
2) sqlplus username\password@hostname:1521\service_name

I do get the error ORA-06401: NETCMN: invalid driver designator

I did try using the SQLPLUS \NOLOG
Connect username\password@hostname:1521\service_name

I still get the same error.

I did manually type all the commands to make sure no additional charaters coming and etc...How shall I overcome this...
