1. Click Start, and then click Run.
2. In the Open box, type cmd and then click OK.
3. Open the following directory:%drive%\WINNT\Microsoft.NET\Framework\v2.0.nnnnn

   where %drive% is the drive letter on which you installed Windows Server 2003 and nnnnn is the least significant version number of ASP.NET 2.0.

    Note   If you are running a 64-bit edition of Windows Server 2003 do not open the 64-bit directory. Windows SharePoint Services requires that IIS be run in 32-bit mode.

4. Run the following command at the command prompt:aspnet_regiis.exe -iru -enable
5. Close the command prompt.
6. In Internet Information Services (IIS) Manager click Refresh from the Action menu.
7. Verify that ASP.NET v2.0.nnnnn is listed in the Web Service Extension column and that the status is Allowed. If the status is Prohibited, you can change the status by right-clicking ASP.NET v2.0.nnnnn and then clicking Allow.
8. After verifying that ASP.NET is allowed, the next step is to specify which virtual server or virtual servers you want to use ASP.NET 2.0. Proceed to Specifying which virtual servers use ASP.NET 2.0.

I needed this for appache.

http://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.x509certificate.aspx

using System;
using System.Security.Cryptography.X509Certificates;

public class X509
{

    public static void Main()
    {

        // The path to the certificate.
        string Certificate = “Certificate.cer”;

        // Load the certificate into an X509Certificate object.
        X509Certificate cert = new X509Certificate(Certificate);

        // Get the value.
        string resultsTrue = cert.ToString(true);

        // Display the value to the console.
        Console.WriteLine(resultsTrue);

        // Get the value.
        string resultsFalse = cert.ToString(false);

        // Display the value to the console.
        Console.WriteLine(resultsFalse);

    }

}

The steps are:

Start Internet Explorer as Administrator (right click and run as administrator).

Goto Tools-Internet Options-Contents-Certificates

Goto the trusted root Certification Authorities and choose Import.

Now find your certificate and goto Place all certificates in the following store, click browse and click show physical stores. Because you started as administrator the local machine option is available under the Trusted root Certificate Authority. Select this and you are all set.

After this the .svc works.

Let’s start with the table:

drop table deg
/

create table deg
(
  degkey    number not null,
  degdat    number not null,
  degtim    number not null,
  degcelcius    number not null,
  constraint deg_pkey primary key (degkey),
  constraint degdat_fkey foreign key (degdat) references dat (datkey),
  constraint degtim_fkey foreign key (degtim) references tim (timkey)
)
/

drop sequence degkey_seq
/

create sequence degkey_seq
  start with 1
  increment by 1
  nomaxvalue
/

create or replace trigger degkey_trigger
  before insert on deg
  for each row
  begin
    select degkey_seq.nextval into :new.degkey from dual;
  end;
/

After this we use dbmetal to generate the helper classes:

dbmetal /provider:oracle /conn:”Data Source=XE;User Id=gwe;Password=gwe;” /database=gwe /code:gwe.cs

The problem here is that the databasename is the same as a tablename in the schema. To solve this edit the gwe.cs file and change the DataContext name to GWE (all capitals). Also change the constructors to GWE.

Then the code to the degrees.cs:

using System;
using System.Web.Services.Protocols;
using System.Net;
using System.Xml;
using System.Text.RegularExpressions;

using System.Collections.Generic;
using System.Linq;
using DbLinq.Linq.Mapping;
using System.Data.OracleClient;

public class Degrees
{
  public static void Main (string [] args)
  {
    try {
    string degrees=”";
    string success=”";
    GlobalWeatherSoapClient w = new GlobalWeatherSoapClient();

    // We load the string in an xml reader to parse it and find the temperature
    XmlReader reader = XmlReader.Create(new System.IO.StringReader(w.GetWeather(“Groningen”,”Netherlands”)));
    reader.MoveToContent();
    // Parse the file and find the Temperature element its value
    while (reader.Read())
    {
      if (reader.NodeType==XmlNodeType.Element && reader.Name==”Temperature”)
      {
        // Do some regex to find the temperature in celcius
        reader.Read(); degrees = Regex.Replace(Regex.Replace(reader.Value,”^.*\\(“,”"),” C\\).*$”,”");
      }
      if (reader.NodeType==XmlNodeType.Element && reader.Name==”Status”)
      {
        reader.Read(); success = reader.Value.Trim();
      }
    }
    reader.Close();

    System.Console.WriteLine(degrees + success);

    if (success==”Success”) {
      System.DateTime d = System.DateTime.Now;

      string connStr = “User Id=gwe;Password=gwe;Data Source=XE”;

      GWE db = new GWE(new OracleConnection(connStr));
      // get datkey
      var q1 = (from p in db.Tims where p.TimHour==d.Hour select p).Single();
      var q2 = (from p in db.Dat where p.DatYYYYMmDd==(d.Year*10000)+(d.Month*100)+d.Day select p).Single();
      DEG deg = new DEG();
      deg.DEGKey=1; // dummy
      deg.DEGCeLcIUs=Convert.ToDecimal(degrees);
      deg.DEGdAt=q2.DatKey;
      deg.DEGTim=q1.TimKey;
      db.DEG.InsertOnSubmit(deg); 
      db.SubmitChanges();
    }
    }
    catch(Exception ex) // catch all exceptions so the batch continues
    {
      Console.WriteLine(ex.ToString());
    }
  }
}

build:

csc /r:dblinq.dll,dblinq.oracle.dll degrees.cs gwe.cs GlobalWeather.cs

And schedule every hour in windows.

Let’s create a .net application which gets the current temperature from a webservice every hour and adds them to a new fact table. We gonna use Windows Communication Foundation and Linq in this example.

In this part we gonna create a webservice client to the weatherservice. In the next part we gonna add the linq part to load the temperature in the oracle database.

I found a pretty nice webservice that is free and also has the european weather:

http://www.webservicex.net/globalweather.asmx

First thing is to create a stub for the webservice:

svcutil.exe http://www.webservicex.net/globalweather.asmx?wsdl

This creates a GlobalWeather.cs stub and an output.config file which contains the bindings.

Ignore the errors, this is because there are other than soap ports in the wsdl.

rename the output.config to degrees.exe.config

create the client degrees.cs:

using System;
using System.Web.Services.Protocols;
using System.Net;
using System.Xml;
using System.Text.RegularExpressions;
public class SetCoverImage
{
public static void Main (string [] args)
{
GlobalWeatherSoapClient w = new GlobalWeatherSoapClient();

// The service returns a plain string
Console.WriteLine(w.GetWeather(“Groningen”,”Netherlands”));

// We load the string in an xml reader to parse it and find the temperature
XmlReader reader = XmlReader.Create(new System.IO.StringReader(w.GetWeather(“Groningen”,”Netherlands”)));
reader.MoveToContent();
// Parse the file and find the Temperature element its value
while (reader.Read())
{
if (reader.NodeType==XmlNodeType.Element && reader.Name==”Temperature”)
{
// Do some regex to find the temperature in celcius
reader.Read(); Console.WriteLine(Regex.Replace(Regex.Replace(reader.Value,”^.*\\(“,”"),” C\\).*$”,”"));
}
if (reader.NodeType==XmlNodeType.Element && reader.Name==”Status”)
{
reader.Read(); Console.WriteLine(reader.Value.Trim());
}
}
reader.Close();
}
}

csc degrees.cs GlobalWeather.cs

degrees.exe

<?xml version="1.0" encoding="utf-16"?>

Success

The service returns the temperature in my region.

Next step is to load it into the database. (see part 2)

Over here in Holland we have another ‘problem’. We have peak and dew hours for the electricity. Also the certain holidays and the weekends are dew prices.

Lets start with creating the schema:

create user gwe identified by gwe;
grant connect,resources to gwe;
connect gwe/gwe

After this, create the dat dimension as showed in the previous blog.

Now the time dimension:

create table tim
(
 timkey    number not null,
 timhour    number(2) not null,
 timelekhoog    varchar2(1) not null,
 constraint tim_pkey primary key (timkey)
)
/

drop sequence timkey_seq
/

create sequence timkey_seq
 start with 1
 increment by 1
 nomaxvalue
/

create or replace trigger timkey_trigger
 before insert on tim
 for each row
 begin
 select timkey_seq.nextval into :new.timkey from dual;
 end;
/

create unique index timhour_idx1 on tim (timhour)
/

insert into tim (timhour,timelekhoog) values (0,'Y');
insert into tim (timhour,timelekhoog) values (1,'Y');
insert into tim (timhour,timelekhoog) values (2,'Y');
insert into tim (timhour,timelekhoog) values (3,'Y');
insert into tim (timhour,timelekhoog) values (4,'Y');
insert into tim (timhour,timelekhoog) values (5,'Y');
insert into tim (timhour,timelekhoog) values (6,'Y');
insert into tim (timhour,timelekhoog) values (7,'N');
insert into tim (timhour,timelekhoog) values (8,'N');
insert into tim (timhour,timelekhoog) values (9,'N');
insert into tim (timhour,timelekhoog) values (10,'N');
insert into tim (timhour,timelekhoog) values (11,'N');
insert into tim (timhour,timelekhoog) values (12,'N');
insert into tim (timhour,timelekhoog) values (13,'N');
insert into tim (timhour,timelekhoog) values (14,'N');
insert into tim (timhour,timelekhoog) values (15,'N');
insert into tim (timhour,timelekhoog) values (16,'N');
insert into tim (timhour,timelekhoog) values (17,'N');
insert into tim (timhour,timelekhoog) values (18,'N');
insert into tim (timhour,timelekhoog) values (19,'N');
insert into tim (timhour,timelekhoog) values (20,'N');
insert into tim (timhour,timelekhoog) values (21,'N');
insert into tim (timhour,timelekhoog) values (22,'N');
insert into tim (timhour,timelekhoog) values (23,'Y');

commit

Now the fact table and the foreignkeys:

create table gwe
(
 gwekey    number not null,
 gwedat    number not null,
 gwetim    number not null,
 gweelekhoog   number(10,5) not null,
 gweeleklaag   number(10,5) not null,
 gwegas        number(10,5) not null,
 gwewater      number(10,5) not null,
 constraint gwe_pkey primary key (gwekey),
 constraint gwedat_fkey foreign key (gwedat) references dat (datkey),
 constraint gwetim_fkey foreign key (gwetim) references tim (timkey)
)
/

drop sequence gwekey_seq
/

create sequence gwekey_seq
 start with 1
 increment by 1
 nomaxvalue
/

create or replace trigger gwekey_trigger
 before insert on gwe
 for each row
 begin
 select gwekey_seq.nextval into :new.gwekey from dual;
 end;
/

declare l_datkey number;
begin
 select datkey into l_datkey from dat where datdate=trunc(sysdate)-1;
 insert into gwe (
 gwedat
 ,gwetim
 ,gweelekhoog
 ,gweeleklaag
 ,gwegas
 ,gwewater
 ) values (
 l_datkey
 ,1
 ,0
 ,0
 ,0
 ,0
 );
end;
/

commit;

The fact table is initialized with 0 values at the date yesterday.

Now we can use the following stored procedure to add meter measures.

create or replace procedure tussenstand( p_datumin date

I think it is handy to create this dimension in it’s own schema:

create user dat identified by dat;
grant connect,resource to dat;
grant create public synonym to dat;
connect dat/dat
run the above script
grant select on dat to public;
create public synonym dat for dat;

Now everyone can use the dat dimension.
