Could not connect to a remote Oracle db

Question

Hello ,
I would to connect with Sqlplus ( Installed Oracle version 9i Release 1 (9.0.1.1.1) for Windows) from my external machine , runnig with Windows XP as OS , to a remote Oracle 10g db installed on a virtual machine running with Ubuntu as OS .
The same senario should be working in the other direction ( from Ubuntu ( Virtual machine ) to Windows XP ( external machine ) .
The DBlinks between the two dbs were well created at both sides.
At Windows side ( external machine ) the tnsnames is already updated .
At Ubuntu side and in order to allow listener accept remote connections, the following command was executed :
EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
At Ubuntu side there is no tnsnames file to update .
I try to connect from both sides to the remote linked db but no result was obtained and the same error occured :
- From external machine side :
SQL> select * from Client1@XE;
select * from Client1@XE
ERROR at line 1:
ORA-12154 : TNS: could not resolve the connect identifier specified
- From virtual machine side :
SQL> select * from Client4@ING3;
select * from Client1@XE
ERROR at line 1:
ORA-12154 : TNS: could not resolve the connect identifier specified
I'm not sure , but the reason could be the missing settings that have to be filled in the missing tnsnames file at Ubuntu Side .
Could you please tell how and where to add the missing tnsnames file at Ubuntu side?
Thank you
khaled

Try replacing
jdbc:oracle:thin:@SFOServer:1521/DevDB
with
jdbc:oracle:thin:@SFOServer:1521:DevDB
