I can connect to the instance on the server machine like that:

$sqlplus "primal/PRIMAL@DC"

then I copy the network connection description of DC to local file tnsnames.ora. but when I connect to the Oracle again:

C:\sqlplus "primal/PRIMAL@DC"

I got this message:

ERROR:
ORA-12560 TNS:protocol adapter error

how can I resolve this problem?
thanks.
