how to no-touch deploy the db access winform?

hello
i write a winform app,in the form there is a datagrid and a button.when i click the button,it connect to the oracle,and retrieve the data to display them in the datagrid.the button click event code as following:

            private void button1_Click(object sender, System.EventArgs e)
            {
                  DataSet dataSet1=new DataSet("dataset1");            
                  String connectionString="Data Source=zbcdb;User Id=scott;Password=password;";
                  OracleConnection connection1=new OracleConnection(connectionString);
                  OracleCommand command1=new OracleCommand("select * from emp");
                  command1.CommandType=CommandType.Text;
                  connection1.Open();
                  command1.Connection=connection1;

                  OracleDataAdapter oracleDataAdapter1=new OracleDataAdapter();
                  oracleDataAdapter1.SelectCommand=command1;
                  oracleDataAdapter1.Fill(dataSet1,"emp");
                  dataGrid1.SetDataBinding(dataSet1,"emp");
            }


both the visual studio and oracle database are installed in my machine,when i try it in my machine,it works well,but after i copy the "exe" file to the iis(NO-TOUCH DEPLOYMENT),and call it from the OTHER client machine,the following exception is thrown:

as you can see,the client can't find the "oci.dll",because i haven't installed the oracle client software in the client machine,and i don't want to install ANY software in the client side. so that i try to copy the "oci.dll" to the same directory in the iis as the exe file.but client can't find it EITHER.maybe i should write the config file to tell the client where to find the "oci.dll",but i don't know how because i am a newbie to dotnet.


who can tell me how to solve the problem?

thank you very much!!!!!
