Hi all

I have added a new program to be downloaded for free from http://www.eliasen.eu/DownloadSoftware.aspx. This time it is a program to help you do two things:

1. Check an XML file to see if it is well formed
2. Validate an XML file against an XSD schema

I have had the need for a small utility to do this several times, in case a customer has some XML, and they want to know if the XML is even valid. The check for well formed-ness can be done by simply opening the file in Internet Explorer, but that is just soooo slow for large files. I tried a 70MB XML file once. It took IE a couple of hours to open it and tell me what was wrong with the XML. My utility did it in a few seconds.

So, use it if you want...

Hi all

Today, I took the 70-241 exam in BizTalk 2006 R2.

I passed, and am now MCTS: BizTalk Server 2006 R2

I have now passed the exams in BizTalk 2000, BizTalk 2004, BizTalk 2006 and BizTalk 2006 R2. Anyone else out there who has done this?

Hi all

At Logica we often participate in different events where employees compete to see who rides their bike more often to work, who walks the most steps in a month, and so on. After a month of competition, we end up with a spreadsheet, where I may have walked 180.000 steps, but my colleague Henrik only walked 78.000 steps (He is kind of a wimp )

So lets say that we want to give a prize to one of us, and Henrik should have a chance of 78000/(78000+180000) (30,23%) of winning and I should have a chance of 180000/(78000+180000) (69,77%) of winning. As the number of points and the number of contestants get bigger, this becomes increasingly difficult to manage.

Therefore, I have written a small winforms program, that helps you manage this. You can add as many contestants as you like, and give them points. If you are only interested in a "normal" draw, you can just give all contestants one point.

Screen shot:

The program not only does the draw, it will also:

• Give you an overview of the contestants, their points and their chance of winning, which is dynamically updated each time a contestant is added
• Give you the opportunity to simulate any number of draws, to ensure that the program is random. When doing the simulation, the percentage of wins by each contestant is shown next to the chance of winning, so they can be compared.

I will gladly take comments, bug reports, suggestions, postcards, et cetera

The documentation can be found at http://www.eliasen.eu/DownloadSoftware.aspx#documentation and the program can be downloaded at http://www.eliasen.eu/DownloadSoftware.aspx#winform.

I hope this comes in handy to someone.

Hi all

I am using http://www.last.fm to keep track of what I listen to, and to get inspired to listen to some new music that I didn't know I liked.

You can find my profile at http://www.last.fm/user/eliasen and you can find information about an excellent Danish band Baal at http://www.last.fm/music/Baal. Please note, though, that I listen to the Danish band Baal, and not the Japanese band that unfortunately shares the band name Baal with the Danish band.

Anyway, the point of this blog post is, that it seems that I am currently the top listener of Baal:

This means that I listen to more Baal than all that listen to either the Danish or the Japanese band...

I know... Get a life, damn it!

Baal have a web site at http://www.baalworld.com - try it!

Hi all

It is time for the third posting in my series about using BizTalk to integrate to Excel spreadsheets. My first two postings are here (Installation) and here (The schema generation wizard).

This third posting is a talk about the runtime, and how it works.

The setup

To start out, I have done a simple test, and you can find my project

It has a simple spreadsheet and a schema for this spreadsheet (both are described in my previous post) and the setup basically just has a FILE Receive Location and a send port with a filter that takes everything from the Receive Port the Receive Location belongs to. My aim is to see how fast the Spread Disassembler is.

First, a short description of my setup:

My BizTalk installation is in a Microsoft Virtual PC 2007 virtual machine.

The host machine is a Hewlett Packard 8710w laptop with an Intel Core Duo T7700 2,4GHz CPU, 2GB of RAM and Windows XP Professional Service Pack 3 and completely updated as of 7'th December 2008.

The guest system is a virtual machine which has one 2,4GHz CPU, 1GB RAM and Microsoft Windows Server 2003 R2 Enterprise Edition SP2 - also completely updated as of 7'th December 2008.

The test

I created 999 copies of the same spreadsheet and moved them into a folder watched by the receive location. They were read, transformed into XML, and output into the output folder in 3:19 minutes. This is an average of 5 spreadsheets per second.

This took me by surprise - I had expected it to be faster. So I decided to do things more academic than looking at the time stamps of the output files. After all, there are PLENTY of functionality that could be the time consumer. So I created a BAM Activity and View, tracking when my Receive Port starts and when it ends.

A table showing the average processing time can be seen here:

So it is pretty clear, that performance drops drastically when the load increases. I do not blame this on the Spread Disassembler, though. Since this is a virtual PC, with SQL Server on the same box as BizTalk, the mere I/O operations when writing all the output files to the hard drive conflicts with the I/O operations of BizTalk using the MessageBox. I find this a much more likely issue for the drop in performance than that the disassembler should get slower just because more messages come in.

So, to sum up, it seems that the Spread Disassembler can take a pretty heavy load - Up to 2643 messages per minute (44 messages per second). This is given less than ideal operating and hardware conditions, but optimal conditions with regards to the BizTalk Server not doing anything else at the time.

Maybe in a later post I will take a look at more complex spreadsheets/schemas and also test the performance of the assembler.

Hi all

The company hosting the eliasen.dk domain went bancrupt last friday (19'th December 2008), and I only just found out this morning (Monday the 22'nd December).

So basically, everything since my last backup (27'th November 2008) is gone!

Right now, I am trying to setup the blog on the new server and trying to see if I can repost the blog posts I have written since the 27'th November.

Hi all

A new functoid has been added to the collection of functoids that an be downloaded at http://www.eliasen.eu/Downloadsoftware.aspx.

The functoid simply takes one parameter, which is used as a key against BizTalks app.config (The BTSNTSvc.exe.config file in BizTalks installation folder) to read an application setting from the appSettings group.

So given a .config file like this:

<appSettings>
<add key="eliasen" value="eliasenValue" />
</appSettings>

and the parameter "eliasen" to the functoid, it will return "eliasenValue". If the key cannot be found, an empty string is returned.

And the documentation has also been updated - look at http://www.eliasen.eu/DownloadSoftware.aspx

Hi all

I have added a new functoid to my functoid library.

This functoid will take a string, that is separated by some character as input and split it up into the substrings it is, given the separator. It will then return the substring given by a third parameter.

So for instance, given these three inputs:

1. Jan,Eliasen,BizTalk
2. ,
3. 1

You would get "Eliasen" as output.

You can download my functoid library at http://www.eliasen.eu/DownloadSoftware.aspx and here you can also find updated documentation describing this new functoid.

Hi all

As you have probably read in my previous posts this month, I have started creating a functoid library, which is freely downloadable if you want to. Now, I have also written some documentation for it (Wauv, I know...). So go to http://www.eliasen.eu/DownloadSoftware.aspx for the software, and here you can find a link to http://www.eliasen.eu/files/eliasen.eu.documentation.docx which contains the documentation for the downloadable software.

Hi all

I have added a new functoid to the collection of functoids I am building. This time, I have programmed a functoid that converts between different datetime formats, which comes in handy when mapping between two schemas that have date elements, that require different formats of the date.

You can find version 4 of my functoid collection at http://www.eliasen.eu/DownloadSoftware.aspx
