There are few things here.

  1. Use Net8 assistant to configure your connection. Better to do it this way if you are not familiar with tnsnames.ora and sqlnet.ora files.
  2. Make sure you have <<ORACLE_HOME>>\bin folder in the beginning of your system path. You should have set PATH=<<ORACLE_HOME>>\bin;%PATH%; somewhere at the end of clients autoexec.bat file. If not alreay there, add and reboot the machine.
  3. You should have sqlplus.exe in <<ORACLE_HOME>>\bin folder to absolutely test your connection. If you don't, then that means you may have done "Application user" install only.
