The ORA error is self-explanatory :
ORA-01017: invalid username/password; logon denied
Cause: An invalid username or password was entered in an attempt to log on to Oracle. The username and password must be the same as was specified in a GRANT CONNECT statement. If the username and password are entered together, the format is: username/password.
Action: Enter a valid username and password combination in the correct format.
