Re^4: Database connection over a network without having a local TNS entry

The error message is

C:\Neshat\Perl-Scripts>perl dbconn.pl
DBI connect('database=FO;host=neshat.com;port=1521','abcd',...) failed
+: Can't connect using this syntax without specifying a HOST and
 a SID at dbconn.pl line 9

I am able to connect using the same parameters using jdbc. So I don't think that there should be any firewall issue. But still I am not very sure.
