My first time working with Oracle. I Installed 11g release 5 32bit client on a windows xp machine, but I can't get the tnsnames to appear on Microsoft ODBC administrator configuration page. I did try putting the tnsname.ora file in Oracle_home or Oracle_Home\Admin folder, no luck. Also, I can't find tnsping.exe anywhere on this XP machine. Where can I download tnsping.exe for Windows XP? Thank you very much in advance for your help.
