Answer 1

You call conn.Open(); after OracleCommand userCommand = new OracleCommand("Select...'", conn); Try open connection then make command.

And what error you get? It look good.

    //Get the User ID for the current user. 
    OracleConnection conn = new OracleConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);


    //conn open before next using
    conn.Open();    



    OracleCommand userCommand = new OracleCommand("Select cust_id from CIS_CUSTOMER_TABLE where cust_username ='" + Session["username"].ToString() + "'", conn);
    OracleDataReader userReader = userCommand.ExecuteReader();
    string User_ID;
