# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, March 15, 2004 1:07 PM by Patrick Wellink

Great summary, but I think that having GUIDs as a key have some great advantages as well, like:

- garanteed uniqueness across applications/servers
- support for key initialisation by the client (something you can't do with identities).

I wouldn't like to give that up to get smaller indexes. How often is bare-bone performance the one and most important required feature of a system anyway? Not often, I think.

Anyway, what was the question that started this discussion?

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, March 15, 2004 1:22 PM by Patrick Wellink

Carlo.......

About Statement nr 1
----------------------

- garanteed uniqueness across applications/servers

Don't Worry let MS-SQL take care of that. Or do you mean a Replicated Scenario.... Because this is one of the few scenario's where guid's are ok to use as a PK.

Statement Nr 2
_-----------------

- Support for key initialisation by the client

This is something you don't need. Have the sproc to create a record return the scope_identity() and everything should work fine.

Sure sure when you use dynamic SQL it could be a little tricky....

BUT THIS IS SOMETHING THAT SHOULD BE AVOIDED. Always use stored procedures to execute an insert.

Let the database worry about ID's and integity. Choosing a GUID will work for a small application. But when performance is an issue FORGET IT.

Choosing a GUID as PK can have SERIOUS implications in large tables. ( A simple insert that takes 30 seconds )

So forget the GUID and do it the proper way.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, March 15, 2004 2:45 PM by Patrick Wellink

Sorry? Forget about GUIDs? I couldn't disagree more.

I do agree that you should take care when using GUIDs, like you should take care when using any technology. But by declaring GUIDs dead, you miss the point here.

It's like saying that starting too many threads will slowdown the OS and then declare multi-threading a bad technology.

I think that great programmers use common sense to decide instead of this kind of generic rules based only on raw performance. Sometimes it's better to use GUIDs, sometimes it's not. Not all tables will grow to over a million rows.

BTW: It's quite a statement to say that just the choice of key type will lead up to 30 second inserts. Where did you find/experience this figures?

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, March 15, 2004 3:29 PM by Patrick Wellink

Well try it yourself. Create a table with a couple of fields (20 or 30 or so) and create a clustered index on the GUID.

Now start inserting records..........
Not just 10 or 20 but 100.000 at a time and watch performance degrade.....

And yes. Also for small files try to avoid a guid...

For example We create a table Countries with three fields

1 GUID
2 ISO CODE
3 DESCIPTION

There is nothing wrong with this file whatsoever I completely agree with you. But now we have a customer table with 3 million records that has a countrycode.....

By using the GUID we have increased the table (on disk) with 3.000.000 customers * 16 bytes = 48 Million bytes

By using an ID the table would be 3.000.000 * 4 bytes = 12 Million Bytes

So a difference of 36 Million Bytes.

And that is only for one field..... Suppose there is also a language table, a currency table etc......

I am not declaring the GUID dead. I only tell people to use it when there is a Reason for it.....

And Performance problems always come after the programmers are gone and the files start to grow.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, March 15, 2004 3:50 PM by Patrick Wellink

Okay, I completely agree with you there.

You can argue about the meaning of winning 36 MB when a regular harddisk is 20 GB or over, but that's too easy ;-). When you expect 1 million rows, you should better take this into consideration.

But you just can't wave away the benefits of a GUID, both for me as a developer as for you as a DBA.

For me as a developer it's very handy to know an entities key at the moment it's created, and not have to wait untill it's persisted to the database. A GUID gives you that possibility.

For you as a DBA, you must have been in a situation where you wanted to migrate a portion of staging data to production with a new release and you couldn't do it right away because keys overlapped. At least happened to me a couple of times in the last few years.

These are things that define the overall maintainability of the system and I think that is as important as it's performance.

Saying that, I think we agree more then I initially thought, which is good to know... ;-)

Run 1000 inserts on an identical table only the ID column Differs. And in the small test the difference was almost 5 seconds.....

Carlo one more comment :

Quote : For me as a developer it's very handy to know an entities key at the moment it's created, and not have to wait untill it's persisted to the database. A GUID gives you that possibility.

THAT IS THE PROBLEM. You create a key and you don't want to wait until SQL has persisted the key...... INTEGRITY.......

The only way to know for SURE the key can be used is if it is persisted in the database. Otherwise the stuff can become corrupted.

And after the little test i hope you understand that me as a DBA am not happy with poor performing databases..... Better a good solid design from the start that will perform always.

Unfortunately when there is a Oracle DB involved everybody screams they need a DBA but with SQL everybody seems to know how things work.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, March 15, 2004 4:50 PM by Patrick Wellink

O jee, this can lead into an endless discussion ;-). But anyway, a little reaction on your note.

Integrity is a crucial thing, but that's exactly the reason why I want to know the key upfront. Because with that I can persist all related records in one batch in one transaction, instead of round-tripping the server for every record. I guess that even IMPROVES performance by shortening the life-time of the transaction. Of course, there are ways to get around the round-tripping, like using stored procedures, but that often gets complicated, especially in master-detail kind of scenario's.

But your performance figures are very impressive. You made your point about the GUIDs performance very clear and I now also feel one should take care about when to use GUIDs. Good job.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, March 15, 2004 4:55 PM by Patrick Wellink

Thanks carlo.

This is exactly why I wrote the article. Everybody uses the guids because they are so easy to use.

Sure you can use them, but with care and only when needed, not by default.

And indeed I will not discuss integrity with you.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Tuesday, March 30, 2004 9:51 AM by Patrick Wellink

I read this article just some minutes ago. Interesting topic that never ends. The comment of Carlo is what I would have written. But then my ramblings.. WHY would you put a clustered index on a PK? Choose a column where costly queries would benefit from. The insertdate for statistics for example or if data can be grouped it could be such an attribute like city, country or the combination gender with date of birth :)

Almost all projects I started were first using int/identities as PK's but most database were getting a replication treatment after some time. Using guid's as PK's is a wise decision when you know that database availability and growth are important issues and you don't know what kind of fail-over scenario will be used.

Using guid's has nothing to do with easier development in for example the middletier. I can only see a clear advantage for the dba with a minimal performanceloss. As said earlier the PK is 4 times bigger but this disadvantage does not compare to most total record lengths of tables that have lots of modifications compared to current hardware specs and prices, maintainability and performance gain in the applicationlogic.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Tuesday, March 30, 2004 11:36 AM by Patrick Wellink

If you create a table in SQL and you assign it a primary key, this becomes the default clustered index.

You have to change it in nonclustered.

The examples you give, CITY and Country are NO candidates at all for a CLUSTERED index. And indeed Only when you replicate you could use a GUID in a table.

And have you tried the query example ?. If it doe'n't make a big difference just increase the loop to 100.000 and see performance degrade.

The performance Loss is not minimal.

And if you know what you are doing you can use guids. (only in a replicated scenario). But unfortunately lot's of people design a table in the Enterprise Manager, they select a UniqeIdentifier as the primary key and then it becomes automatically a clustered index.

I hope this answers your question, Why put a Clustered index on a GUID.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Tuesday, March 30, 2004 6:29 PM by Patrick Wellink

Why wouldn't city and country not be a perfect candidate for a clustered index? It all depends of the costs of an insert againt the win of disk I/O with a select statement.

Ofcourse you will want columns in a clustered index that preferably won't change in time. But that is just preferable in most databases.

What I ment is that using guids as primarykey WITHOUT using it in an clusteredindex (because that would result in random datapage inserts thus resulting in huge performanceloss) relative to it's 4x size of a normal int does not result in a bad performance. You cannot test this in a queryanalyzer session just on SQL server because you must do these kind of test from a normal application that also generates the guid.

The performance loss is in most situation's neglectable because of application logic and network i/o.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Wednesday, March 31, 2004 8:49 AM by Patrick Wellink

No CITY and Country would neve be good clustered indexes.

As a rule of thumb, every table should have a clustered index. Generally, but not always, the clustered index should be on a column that monotonically increases--such as an identity column, or some other column where the value is increasing--and is unique. In many cases, the primary key is the ideal column for a clustered index.

City and country both share the same caracteristics. 'They don't Increase monotonically' and 'are not unique' that is why I would never create a clustered index on them.

Second....

I have seen the performance hit on a logging table. The logging table would grow to over 1.5 million records. The last insert took over 30 seconds and caused a Timeout.

So you really have to know hat you are doing if you are playing around with guids. If you do, it is ok to use them.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Friday, May 14, 2004 10:05 PM by Patrick Wellink

This is currently a heated discussion within our organization. I personally do not care if my PK is a guid or autonumber. I DO care about generating this ID in the middle tier instead of at the database level. Can you please elaborate on why this is a bad practice and should be avoided? I know it revolves around database integrity, but I can remember the exact issue. Any help or other refrences would be greatly appreciated.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, May 17, 2004 10:52 AM by Patrick Wellink

Well I think it is better to let the database decide what a key is than decide yourself.

But ok here is the underlying logic....

Since the database decides if a record is valid, only the database can assure me that a key is valid. And a key is only valid if a record was succellfully committed....

By assuming that a GUID is unique you think you have solved the problem of creating keys....

But a key is only valid if it is accepted by the database... (and commited) So this involves a round trip to make sure it is accepted.

Since you are doing a roundtrip anyway why not get the pk back from the database in that same roundtrip.

I know this is not true for specific situations, but this is the general rule

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, May 17, 2004 4:24 PM by Patrick Wellink

Patrick, thanks for the response, it has been very helpful. I too am also strongly opposed to the use of GUID's as a priamry key. As you have pointed out the disadvanteges far outweigh the advantages of global uniqueness. (Even though this too can easily be accounted for with ints as you have pointed out.) Here is my exact problem, our team is convinced that a round trip can be avoided through the use of guids and an isolation level of serializeable. We will be using serializeable transactions for both reads and writes. In this scenario, is there anything else you can think of that would be determental to data integrity? What about cascading updates and deletes? I just need some sort of concrete evidence to turn the tides and convince everyone once and for all. This thread has been extremely helpful and has made a huge impact in our organization. I would like to thank everyone who has responded.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, May 17, 2004 4:42 PM by Patrick Wellink

Run the query !!!!!

If you don't see a difference your machine is to fast, just increase the numbers a little

This whole discussion was about performance.

The reason why you shouldn't use GUID's is performance...

And I mean performance in life situations with lotsa records....

Sure sure in a test environment everything works fine, until you start inserting a serious amount of records.

Success

There seems to be some misunderstanding about advantages of clustering here - with a clustered index the index is the data so once the page entry of the index is found that page has the data - there are OFTEN times when a non-unique key is the best for clustering - e.g. take an app where you have a number of client's and their purchase history - chances are you will want to pull back full purchase history for each client - so on the purchase history table the id of the client would be the one to cluster - keeping all data for same client together in the same data pages so once SQL Server has retrieved a page most of the required data is there in the same page

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Friday, June 04, 2004 8:49 PM by Patrick Wellink

One thing that I found VERY interesting wasn't the bulk insert times, but rather comparing the search times on large tables with guids vs ints. Making all things equal by creating non-clustered indexes on all tables, I found that the search were between 35-40% faster by using the integer index!!! This test involved 2 sets of 4 tables with 10,000 rows each. One set was for integer primary keys, another for guids. The first table represents an "accounts" table, and the other three were joined in one-one relationships based on the primary key.

GUID is not always bad, sometimes you have to but you need to have a real strong argument to use one.

First off, I rolled over the floor, laughing, because of your funny post. And thanks for calling me a "very experienced C# programmer". :)

But seriously, I can't remember your question and deleted the emails, but I must've wrongly interpreted your question. I can't remember you asking this or I would've come up with an answer. If you could email our conversation again, I'd be happy to look into it again! :)

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Friday, July 23, 2004 11:42 PM by Patrick Wellink

Patrick,

I am about to use GUIDs since I have to support an online/offline briefcase model.

GUID is the only way I can create data in the offline mode without a trip to the server for a PK. The other option is to code a complex "pending" local database to run parallel with the server-approved local database or some-such malarky. Tell me if there are other solutions you have seen that are possible.

(There is enough data on the clients to have necessitated MSDE. I don't plan to use Sql Server's merge replication feature, though I am aware that it works and uses GUIDs. Our system is more real-time when online than merge-replication can offer. I have some data that is read-only for the remote users, and other that they must author -- use GUID only for the data they must author or standardize with GUIDs everywhere? I have control of schema.)

In my case, GUIDs seem the best choice.
Also, the data volume is not large whatsoever.

Any last suggestions, blessings, wardings?

Very good thread; a meaningful debate.

Well if you feel you have to use GUIDs, use them, But one of the issue's in the debate was, to only use them when you really have to. So the second part of your question is a definite no. (should we use them everywhere)

In the scenario you describe I would probably use a GUID as well.

I guess any good coder will spot the error almost instantly because the absence of brackets in this case is clearly going to cause confusion.

I ALWAYS use {} to keep code readable and maintainable, even with only one line of code.

And MS released VB for .NET so it's hard to argue they don't make mistakes ;-)

Even guys at MS make mistakes and I've had my share of errors, but I'm just saying that in this particular case, I always use brackets.

I just tried to make clear that the people who invented c# even get confused themselves....

In VB this error would never have happened.
And the code would be more compact.

Something needing only 10 lines of VB code
and perfectly clear to everybody would need 22 lines in C# to be clear.

No wonder all these real programmers (you no c# boyz) need a 40 inc LCD.

De geneste if in deze code is zowiezo overbodig. Je had ze kunnen combineren in een if statement (zie m'n comment op blog zelf). Voor if statements met slechts een statement erna vindt ik {} de leesbaarheid van de code aanzienlijk verminderen, want in plaats van 2 regels heb ik er nu 4, wat het overzicht over een routine vermindert. Blijft een questie van smaak (en teamafspraken!).

# re: Some things can make a Difference

Sunday, August 29, 2004 7:41 PM by Patrick Wellink

Patrick,

In our case (you and me and almost everyone who posts at this blogserver) management did indeed make the decision to change from VB6 to C#. That's kinda odd because management usually knows diddley squad about technology.
But in this case they were advised by very senior consultants and some management of our unit does know a bit about .net (like Mark).

Anyway, it did sound obvious to change from VB6 to VB.NET. But after a while of getting used to it, I like C# better.
Why? There are a lot of reasons, but my choice and reasons don't matter. It's like a religious discussion, no-one will win.
Just use the language you like, depending which solution you want to build.

And as for our discussions about C# and VB.NET...
We like a funny discussion and you bring out the best in us ;-)

# re: Some things can make a Difference

Blame me (for the C# advise)! And I agree that VB.NET does have its place. No language can be good in everything.

By the way, the advise for C# was more motivated by non-language factors than the languages themselves: (non-Microsoft) tool support being an important one...

# re: Why I Like If / Endif

Tuesday, August 31, 2004 11:19 AM by Patrick Wellink

Easy one... when watching/debugging code one of the first things to check is alignment.

Our company policy it to use brackets but I don't agree with that one. The same as also using just one return in a method. If that would be the semantics of a language then the compiler would punish us for being stupid :)

Dennis will probably remember the drills for learning c of the teacher at Zadkine College Christiaan Huygens van 't Hof. Bracket checks and alignment was part of that. The for uninitialized variables but c# won't allow that anymore :) damn those were the days on those f**king old VMS machines.

if statements that contains just one line of code should be put on one line :) but that is my opinion. Not of my employer.

# re: Why I Like If / Endif

Tuesday, August 31, 2004 11:22 AM by Patrick Wellink

B.t.w. the new C++ compiler allows such readable code in .NET that I am thinking of moving from C# to C++ because why use C# when you have workable/readable C++ available?

Then this discussion will turn into a nice VB againt C++ battle like some years ago :)

I've read a number of articles on this topic.

Conclusion: there is NO supported way with v1.0 or v1.1 to specify server GC mode without an unmanaged host...!

With Whidbey (v2.0) and v1.1 SP1 (recently released) there is the ability to specify the gc mode in the application's config file.

According to this article http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/highperfmanagedapps.asp you do not have to worry about ASP.NET applications because they always use the Server GC.

# re: Important to know when building scalable .NET applications

Friday, September 17, 2004 9:32 AM by Patrick Wellink

Hmmm... a lot of contradictory info on this topic.

Why does the article, posted by Erwyn, mention the MSDN article from March 01 in which the CLR is explicitly hosted by an unmanaged host?

How can this article say that ASP.NET always hosts the server GC automatically when in other articles it is said that the workstation GC is loaded when only 1 CPU is available?

It looks like you need another security context for your class (am I right?).

Sounds easier then it is, though.

# re: Ok, a .NET question this time

Tuesday, October 05, 2004 4:36 PM by Patrick Wellink

Well carlo,

I have a component that performs a submitsync (it is from the biztalk samples) if i use this component form a forms app everything works as expected. But if I use it in an orchestration i get error messages.

I really don't know why but some other guru From Microsoft told me submitsync in an orchestration rings a bell and he thought it wouldn't work.

I REALLY need the submitsync Functionality so i now want to wrap that in a service and then call the service from the orchestration....

# re: Ok, a .NET question this time

Friday, October 08, 2004 12:52 PM by Patrick Wellink

My guess is you want your Windows Service to act as a container for a Math component implementing the AddNumbers function?

- Expose the service interface using .Net remoting (note that .Net remoting offers no build-in security)

- Host the Math component in COM+ and generate a proxy referenced by your WinForm client

- Wire up a web service as the Facade over your Math component

And Roland is correct, 320 offers a lot of information on how to service functionality.

# re: Ok Very BASIC .NET Question

Tuesday, November 09, 2004 9:47 AM by Patrick Wellink

I'd like to know more about the stretching. Why and when does it stretch? Why is it so important?

I know with javascript you can get the width of the browser and use it to postback to the server, draw the image with that information, but that's a sucking solution.

I don't know exactly how you can use an image as background in a table and make it stretch along with the table width. Maybe it's easy, dunnow exactly. Then you place some text inside the table and done. I think that's the best solution, because using the width of the browser for the width of the picture isn't hard, but probably a lousy solution.

# re: Ok Very BASIC .NET Question

Tuesday, November 09, 2004 10:00 AM by Patrick Wellink

Well if you have a very small picture as a basis the webpage remains fast if you have limited bandwith. Also if the same picture is used everywhere caching can be effective !

If you generate it all the time over and over again caching is impossible and the webserver would be generating pictures all the time instead of serving webpages.

That's why i want the image to stretch

I see gradient.. I see text.. Why don't you use DX filters in your css classes? Works perfect in IE. If you are doing a intranet site then this works perfect. I used a DX filter to get the gradient and on top of that a generated gif image that contains the text with the fonttype you want to use. If you are using a font that the client already has then you can even forget the image rendering.

# re: Relative References in a VS project

Monday, November 22, 2004 11:47 PM by Patrick Wellink

Never did get it working. Instead, I copied the outputed DLLs of each project to a known relative location as a post build step and referenced those from each (sub)project.

Under project properties, Common Projecties,
Build Events, Post Build Event Command Line, type:

copy $(TargetPath) $(SolutionDir)\bin

This way, you can easily switch from Debug to Release and back again.

I want to use the K8N for a server in combination with a coolermaster stacker box and coolermaster fan. Starting with 3x 200GB (thus ~ 400GB RAID5) and expandable with 3 more in the future (adding 600GB resulting in 1TB). SATA HD's in software RAID 0,1 and 5 partitions. The system should become my file, mail, massstorage, web, database, etc. server at home. Linking my server my primairy workstation with gigabit for ISO's, MSDN, etc.

I would select the MSI if I had to build a workstation. Putting in 3x 120GB 5400RPM disks in RAID 0 to keep the sound down but throughput high. But only if I would have a server that has my documents and multimedia crap stored in a faulttolerant setup.

# re: One advantage of MS over Open Source

Friday, December 17, 2004 9:39 AM by Patrick Wellink

I think most of us will agree that Microsoft has made great improvements on the quality of their products over the last years.
I must admit that in the past I was very sceptical of MS products.
But with the release of W2K and the .NET platform, it's clear MS has made big steps towards a credible partner for enterprise solutions.

And the world agrees, because i.e. .NET has conquered the development market in a way that SUN with Java could only dream about.

The time that Java developers laughed at MS products is over. In fact, I know of a company that's retraining some of it's Java consultants to .NET. ;)

Anyone in IT that still calls Microsoft MickeySoft doesn't have a clue what going on...

# re: One advantage of MS over Open Source

Friday, December 17, 2004 10:01 AM by Patrick Wellink

@Patrick:
I think Microsoft has always released good quality products, it's just that the bugs kept people from using them. Until, as Ernst says, products like W2K came out and proved MS-DOS (like) memory management was the problem in Win98. It had to be compatible. Win2K is based in WinNT.

But also the older Office suite and other products by Microsoft became popular way before they were really stable.

The key to the succes of Microsoft are thing like :
- Best marketing in the world!
- Better good at stealing, then badly self-invented.
- Best marketing in the world!

:)

Look at the XBox, it's not the best system, it's also not a bad system. It's just, like the PS2, _a_ system to play games on. But the succes is from marketing and giving them away almost for free. :)

Same with Whidbey, Longhorn, WinFS, etc. Everyone is just soooo interested because of marketing hype. Why would you want WinFS? Because search is faster? Because for normal users, WinFS doesn't bring much more then that, I guess...

# re: One advantage of MS over Open Source

Friday, December 17, 2004 10:13 AM by Patrick Wellink

Dennis you are Wrong......

XBOX is Much... Much more than a PS2.
because the XBOX is a Media Center Extender as well.

This means that if you have a Media Center PC somewhere in the house you can enyou all the digital media on it everywhere in the house via an XBOX.

This is a pretty cheap solution cause a xbox is under 200 Euro's.

For example some people have Digital TV. The problem with that is if you have more televisions you will buy more receivers.

Now by connection the Receiver to the media center pc you can wacht the digital channel everywhere where there's an XBOX.

I Believe a Media Center PC can serve up to 5 Media Extenders Simultaniously.

So Record once and look everywhere where there's an XBOX.

You can forget this functionality when you buy and PS2.

# re: Problems with the BizTalk SQL Adapter......

Thursday, December 23, 2004 12:59 PM by Patrick Wellink

Hi Patrik,

I agree with you on the performance issue, the SQL adapter is not too quick when it's doing lots of updates. I think this is more due to the request and response messages passing through the message box than the isolation level (I could be wrong though).

To reduce deaslocks with multiple calls, one option is to override the serailazation level in the stored procedure (if you are using SPs). This has helped me a couple of times.

As for the performace, adapters are usually used to communicate with external systems. They use the tracking, and the configurable ports, and retry on failure, which is great if the SqlServer is an another location and the connection is unrelyable. I have started building a C# data access layer when I need quick database access to a local server. It beats the adapter when it comes to performance and error handling.

Regards,

Alan

# re: Problems with the BizTalk SQL Adapter......

Thursday, December 23, 2004 1:20 PM by Patrick Wellink

I tried overriding the isolation level but it didn't really work for me.

I created an Adapter that handles Send calls to SQL and it greatly outperforms the SQL Adapter in all ways, and almost everything is supported.

I am working on a receive adapter now.

Furthermore, you can't win the performance you loose with hardware if the table design is bad.

Faster hardware can increase performance by a factor 2 or so but designing your tables differently can increase performance by 30.000 times....

# re: Possible way to pass object(state) between ASP.NET pages

Tuesday, January 04, 2005 12:59 PM by Patrick Wellink

Indeed, a <b>simple</b> solution, but only usable for <b>simple</b> objects.
Not every object is this easily serializable...

But thanks for the info anyway, Patrick ;)

# re: Possible way to pass object(state) between ASP.NET pages

Tuesday, January 04, 2005 2:57 PM by Patrick Wellink

I don't think the object itself is a problem here, I think it's the length of the url that's the problem.

According to the following kb article, the max length in Internet Explorer can only be 2048 characters.

http://support.microsoft.com/kb/q208427/

And besides that, there are way, way more possibilities! Store it in session, in cache, make a post and submit it to another form, etc, etc.

Most of the time I use hidden fields to store stuff and try to keep away as much possible from both session and querystring.

Btw, the example got the querystring with the code : Request["obj"].ToString()
That in itself already sucks, because what this functionally does is walk through all options (form, querystring and session) untill it has a match.

Why not use querystring, like you yourself specified? It's faster, more secure and much, much more readable.

I think in all this is a bad example of how to pass objects between pages. However, the writer says he wanted to pass between APPLICATIONS! This, I am sure, can be done much better and does not need a crappy solution like this.

What you suggest is nice and common practice but less- or none-usable for passing objects from one application to the next and that's what this example is about.
Then it gets more complicated. You cannot share sessions because the two webapps are separate processes.

Wednesday, January 26, 2005 1:10 PM by Patrick Wellink

Some answers to your questions:

1. You can create a dataform based on a table in a database connection. It's standard in VisStud. So no need for Oracle designer.
2. We have experience with that, but the RAD race team I was part of decided not to use it because it did not fit with the framework we wanted to use.
3 We used a Codegen tool (CodeSmith) to generate code. But we had problems with one of the templates.

The templates will soon be upgraded, so they will not have any unwanted side effects. Such as stripping some parts of database column names.

There are also plans to build UI templates. These templates will generate a WinForms interface or an ASP.Net interface. But these things take time.

I'm sure that if we had these templates we would have given the Oracle boys a hard time.

You'd have your O/R Mappers, but most of the time these don't add GUI. Why should they? It's not their job.

And code generators like CodeSmith could add this and probably have the templates online.

What did Jan do to the column names that the templates screwed up?

Thursday, January 27, 2005 7:29 AM by Patrick Wellink

Guys, it was very simple. I had one template that generated code that did not compile. That was my fault. I somehow managed to get a version that was NOT in our source safe database.

BUT, the templates remove everything from the column until the first underscore. So if you have something like ddd_mycolumnname in your table, the templates would use mycolumnname in all the generated code, with the exception of the stored procedures.

Apparently, this behaviour was intentional. But it's pretty annoying, and time consuming, when you look at the database design and the code doesn't match.

But I believe that unwanted behaviour will soon change!

# re: Rad Race I don't Get it, Please help.....

We also had generated code that didn't compile (lblgen based solution).

Patrick, I've been there, I used Oracle Developer/Designer and I knew that they had a great chance on winning. Why? Well, you didn't have a look at there UI. It looks like, like, well you know like, looks like something like, well like a generated Oracle Designer application. And yes: we should do more, be more productive and CodeGen is one side of the equation, knowing the power of your IDE is the other ;-).
Oracle Designer is great for RAD and needs non demanding customers.
'I want that field to the left'
'No, you don't'
'Yes I really want that'
'Ok, I will generate the app, Start up Forms Developer, navigate through the generated code/forms, apply the change you requested, and add this change to the Post-Generation document'
Just ask some Oracle guys about designer and they all probably had a Post-Generation document and on the size of this document you could tell if they used the right tool. And no, there are no generators for the post generation steps :-)

# re: Rad Race I don't Get it, Please help.....

# re: Code generation Tools for .NET

Friday, January 28, 2005 1:10 AM by Patrick Wellink

And then you find that the generated code does not do everything that you want it to do...
Can you modify/extend the generated code without loosing changes when regenerating the rest?
How hard is it to change the architecture when the application is not as simple as you orginally thought?
Some questions to think about before falling in love with a code generation tool.

CodeSmith's strength is that it provides a code generation platform that can be used in practically any way you like it. That brngs with it some complexity and the need to taylor its templates to your needs, i.e. you need to already have an idea about what design/architecture you want for your app. For serious app development that is not a bad thing. I would get very nervous about tools that do "everything" for me..., because generally they don't. Otherwise many of us would be out of business/jobs very soon ;-)

# re: Code generation Tools for .NET

Friday, January 28, 2005 10:49 AM by Patrick Wellink

What do you mean by "everything"? From GUI to Datalayer or less? Because OR/M do a LOT for you, but not any further then datalayer or perhaps some checks for your business layer.

# re: Rad Race I don't Get it, Please help.....

Friday, January 28, 2005 11:47 AM by Patrick Wellink

The point of Oracle Designer is that you can always re-generate. (like the Borg do). Generate once sounds to me as rather useless in new development (but will be handy if you have a datamodel that is rock solid), I'd rather propose something like generate 'add-ons'. You should look into those matters in your search for Codegenerators. But we both agree that we want to focus on business rules not on the plumbing.

# re: Rad Race I don't Get it, Please help.....

Friday, January 28, 2005 5:20 PM by Patrick Wellink

Okay, now I need to step in here ;-) Comparing Designer to the Borg, tsk. Don't you like Borg?

As you know I worked with Visual Studio, Java and Designer. The point is that codegen is the way to go always. It is not only for undemanding customers. We have made great systems for demanding sites and they are happy. I was a memeber of the jury and I was disappointed to see that C# and Java teams ended on the same level. Mainly because time was wasted on the plumbing. In Designer you can focus on the business logic and you don't have to worry if your screens will work. The ICT industry needs people that can do the plumbing but I don't think our customers should pay us to do that. Let Microsoft and Oracle make compilers for us, let us assemble apps using components and codegenerators. And if the customer wants a field at the left: you can do that with Designer :-) Really. We need not to judge the tools but make up our minds on how we do application development. It is a shame that after 30 years we still don't have the tools that do the work for us. (Ow except Oracle, because thay have the tools ;-) I almost forgot. But now we jump on the Java bandwagon, the collective memory of Designer is erased and at Oracle projects we also are doing plumbing. <Sigh>.

Read this article (http://www.codeproject.com/dotnet/GriffinMyGen.asp) about MyGeneration on CodeProject.
At the bottom there are some discussion threads and "Business Objects shouldn’t be developed one for one per table" is especially interesting...

"I have successfully shipped many projects like this, big .NET apps, and can even out bid Indian based companies doing outsourcing for a dime on the dollar. Give me a SQL database and in a day or so I'll give you a complete, functional object model that can read and write, supports transactions (seemless via TSL) and more. This is the just the beginning.
"

Even with the disscussion about architecture and business objects still going on, it's quite promissing...: "a functional object model in a day" Cool!

"You will see some nice surprises when you start using stuff like LLBLGEN and there are lotsa records......

I doubt it. For example, you can finetune your query by switching from joins to subqueries, which can gain you a lot in multi-table filters with lots of records.

There is no sql doodads can generate that LLBLGen Pro can't.

So, what's the code you ran?

Patrick, thanx for the compliment. You are correct in that dOOdads is extremly lightweight and has almost no overhead over and above ADO.NET. Our dOOdads architecture focuses on serving up your data with an elegant API. We're glad you like it.

Frans Bouma
"There is no sql doodads can generate that LLBLGen Pro can't."

Frans, the SQL is not the issue, it's the underlying archtecture. The two greatest myths I hear all of the time are:

1) Never make business entities map directly to a table (I do it all the time and so do tons of our customers). Of course we can generate them for views too.

2) Never use a DataTable, they're too slow. Nonsense, DataReaders are faster sure, if you never plan to actually use the data you fetch. However when you go to copy the data out of the reader to populate your entities you waste a ton of time a memory and time, and you're garbage collection issues go up significantly on high end web sites. The dOOdads architecture literally never moves the data, it resides in the DataTable. So loading a dOOdad is no more than loading a DataTable, the elegant API is literally "laid over" the DataTable. The dOOdads technique (and our new EntitySpaces due out with 2.0) will really come into play with the terrific advances coming in .NET 2.0 concerning DataTables.

# re: Awesome Code generation !!!!

Monday, March 14, 2005 5:45 PM by Patrick Wellink

Yes, llblgen pro is a bit slower in entity collection fetches than normal datatable fetches. This is because for each row, an object has to be created, filled, added to the collection etc. which is a little more overhead than a new datarow added to a datatable.

Though, with a datatable based architecture you can't use the individual objects without having the datatable around, as the datarow doesn't have a public constructor. So 1 customer always creates one datatable.

In llblgen pro, if you want everything in a datatable, you can of course do that, or in a typed datatable, you can do that too. You can even define the list in code if you want.

As datatables use an arraylist to store the datarows, adding one has a performance hit in the long run, i.e. when there are a lot of rows in the datatable. MS doesn't recommend to fetch more than 57000 rows in a datatable, which is a lot also.

# re: Awesome Code generation !!!!

Monday, March 14, 2005 5:47 PM by Patrick Wellink

btw, I doubt you can fetch 300,000 rows in a datatable in 1 second, or the rows are very very small, but even then.

# re: Awesome Code generation !!!!

Monday, March 14, 2005 5:54 PM by Patrick Wellink

" However when you go to copy the data out of the reader to populate your entities you waste a ton of time a memory and time, and you're garbage collection issues go up significantly on high end web sites."
haha, and how are you filling your datatables, Mike... using Fill()? or copying the data yourself? Either way, it doesn't matter, you're copying data.

I also don't see the garbage collection issues, as you can't re-use the resultset produced by a datareader without copying it to some container (be it a datatable, custom object...).

The overhead you miss is that you don't have to setup fields with every object, just once with the datacolumns. So a datareader fill is then nothing more than creating a datarow and moving over the cells per value. It's a bit faster, but for a price.

Dennis: This post is classical Patrick; no filter between thought and post.

Patrick: As brilliant you are, I still think you haven’t given both products much time to evaluate. As such, you address only the out-of-box experience. Important as this property is for end user products, a software development tool is a different beast. Don’t make too hasty a conclusion. Do stay tuned though, and watch me do the same.

Frans: I haven’t given LLBLGen Pro the time it deserves to fully appreciate its potential power. In fact, I stopped evaluating LLBLGen Pro just one hour after downloading and installing it. The reason was that there does not seem to be a database-diagram kind of view of the database. At least, I couldn’t find it. So I stopped. Sorry.

In Visual Studio .NET 2003, you create a database diagram simply by adding all tables to a newly created empty diagram. The resulting diagram nicely shows the relations. To get a typed dataset, you can drag tables to a XML Schema. The code VS2003 generates may be horrible, I don’t really know. The point I’m trying to make is that I like interacting with a database in a graphical manner.

The Project Explorer in LLBLGen Pro has all the information necessary to build an UML view of the relations between tables (entities). But I still need to make a mental picture of the complete database. That doesn’t make sense to me.

That is probably the feature folks love best about dOOdads. Equal is the default operator so you really don't even have to set that. To be honest I pull off about 80% - 90% of an average project with just that simple approach.

However, there are other ways to load dOOdads via custom SQL. Both the LoadFromSql() and the LoadFromRawSql() methods can be invoked if the dynamic query mechanism won't do what you want.

# re: Awesome Screen Generation..... (part Two)

Tuesday, March 15, 2005 5:34 PM by Patrick Wellink

The beauty of MyGeneration is that if we don't have the template you are looking for it is quite easy to write your own. You pick the template language, VBScript, JScript, C# or VB.NET.

Suppose we don't have a template that will generate a screen directly from a Table, simply, go hand write a screen that does just that, then take it and make a template out of it. The effort pays off big time, and if you share you help others ...

Also, you can swipe code from other templates ...

1. Start Mygeneration…
2. File->New->Project
3. Right Click “New Project” in the treeview and select add “Template Instance”
4. First Enter A name for this Template ( For example NorthWind dOOdad Entities)
5. Select the Template you want. (dOOdad Business Entity C#)
6. Hit the Record Template Input button.
7. Select the directory where the Files will be placed
8. Select the Tables
9. Hit OK

10. You should do step 3 till 10 again for the Business Class and the SQL Stored procedures
11. Make sure you select different directories for everything

12. Now go to Visual Studio.
13. Open a new C# Project.
14. Add an Existing Project wich is the architecture in the \Program Files\MyGeneration\dOOdad ( or some of the subdirs )

15. Now Add all the generated stuff to your project and off you go…..

# re: Data Access Application Block Support....

Thursday, March 17, 2005 1:06 PM by Patrick Wellink

Oh.... I forgot one thing...

Once the dOOdad Project is included you have to select the database driver you want....

Do this by setting Compile to true..
So if you want MS-SQL set the compile option of :

SqlClientEntity.vb
SqlClientDynamicQuery.vb

To True....

Oh and you will need a config file as well....
But you can see that in the samples

and last but not least don't forget to set the settings correct for language and database....

You asked for improvements and using overloadsers is an improvement when using overloaders.

in your case it will look like this:
...
MyEventClass.Dispose
...

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Sunday, May 01, 2005 7:06 PM by Patrick Wellink

Patrick, your point is well taken that GUIDs present a considerable performance issue--and all the cheap RAM and cheap disk space in the world won't help you at I/O time... the real performance hit comes every time you have to suck that ballooned data to or from the disk... all else being equal, it takes twice as long to load 200 bytes of data as it does 100 bytes.

My dilemma: While I am all about carrying the most cost-effective datatypes, I am building a large multi-site application where site autonomy is essential. I have been considering merge replication, but the performance nut in me isn't excited about the cost of repeating GUIDs hundreds of thousands of times over (in foreign key columns, for example).

We need a solution that allows any site to master new records independent of the others, but that will replicate changes to other sites when convenient.

My only thought is to build a mechanism to allocate blocks of integers to the various sites... or acquiesce and use GUIDs...

Even should I do some sophisticated managing of integers, I cannot use out-of-the-box SQL Merge Replication without including the GUID fields in my tables... arrgh!

Any observations on how you'd approach this problem?

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, May 02, 2005 8:20 AM by Patrick Wellink

Well if you really have to do merge replication, adding a GUID is a logical step.

You could indeed have a bigint and then allocate blocsks of integers to site's but i have no experience with that. (sorry)

However, this is just the place where you would introduce a guid.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Friday, June 03, 2005 7:16 PM by Patrick Wellink

GUIDs are useful if you dont know SQL. Talented db engineers have been doing just fine without them for years. Its really sad to read about how "easy" GUIDs will make db development... and how performance is a non-issue because "RAM is cheap" and space is plenty.

That all may be true... but Im a little pissed that no one seems to care about developing quality code. Anyone can build a crappy database and get by. Using a GUID is one way to ensure that your key is unique... building a sound database system is anotherl.

If its 100 ms faster, then its 100 ms better. Using a GUID over an INT because its easy is like fishing for 3 lb trout with 300 lb test line. Sure, its easier... but wheres the sport? Wheres the style.

Long live the INT!

Suck it.

# re: What the .... CLS Compliancy ( VB Got it right all the time )

Wednesday, June 08, 2005 1:04 PM by Patrick Wellink

Dear Patrick,

The link you refer to talks about Cross-Language Interoperability. This means that if you build CLS complient, you need to make a difference between identifiers by more than just casing.
So, in C#, you can use 'int Number' and 'int numBer' and that would be 2 different identifiers.
But to be Cross-Language Interoperable you can't use that because a VB.NET user of your component can't see the difference (because VB.NET doesn't use casesensitivity).
So, the article om MSDN is correct.

However, I'm not sure why you should get this error in a VB.NET conversion, because you didn't / couldn't use 'int Number' and 'int numBer' in VB.NET 2003...

# re: What the .... CLS Compliancy ( VB Got it right all the time )

Wednesday, June 08, 2005 2:16 PM by Patrick Wellink

Well Ernst....

The casing has nothing to do with VB but with the specifications. ( as depicted in the URL above)

I just said that in VB it was always like that.... So I don't have to rewrite my programs to be cls compliant.

My guess is a lot of C# programmers have to.......

No the problem I got was ....

Thursday, June 09, 2005 9:31 PM by Patrick Wellink

The last two or three weeks, I started programming in VB.NET to build multi-threaded embedded applications. Today I had to switch back to C# for half an hour for some maintenance. What struck me was that one gets accustomed very easily to on-the-fly re-compiling during editing in VS2003. Hence, I expected the error indicators (i.e., the wiggly lines). I actually cursed the C# compiler for telling me *after* the compile that I failed to add the semi colons.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Monday, June 13, 2005 10:35 PM by Patrick Wellink

One aspect of a GUID over an INT that I have not seen discussed is the security aspect of a GUID. Having a constantly incrementing key be visible to users, as in a web based scenario where the ID of a record is often passed back and forth, is a security risk. Even if the value is encrypted, just the fact that the key increments and is "guessable" provides a hacker an easier method of determining how to break the key. A random GUID is much much harder to crack.

Just my 2 cents with another piece of info to help people make their decisions.

# re: GUID is not Always GOOD !!!!!!! (a true RTFM story)

Tuesday, June 14, 2005 4:19 PM by Patrick Wellink

What has this to do with good database design....

Where is the leak if you use parametherized queries ???

I dont get it this is only true if you use inline dynamic SQL.....

and if you do that you could as wel program a guid for everything........

Hyperlinks etc could still use GUIDs ..... I never said there shouldn't be any GUIDS.

But NEVER AS A PK.....

Hello Patrick,

I am intrigued by your adapter, but am having a problem trying to generate a schema with it. When I try to generate the schema using the "Add Adapter Wizard" after selecting "SPX" and clicking "Next", I get the following error:

"Unable to obtain service organization from the adapter.
Value cannot be null.
Paramter name: stream"

I'm assuming the code is based upon the sample file adapter in the SDK and is just looking for the CategorySchema.xml file. I'm not sure where to place it though, and this is truly the solution. Let me know.

Thanks!

# re: GUID can be good but should never be clustered

Monday, August 07, 2006 10:48 AM by Ross

Though this is an old thread, I am compelled to add to it for anyone that does a web search and reads through attempting to make a decision on GUID vs. INT.

I'd like to summarize all of the above into a simple, concise logic fork as a guideline to GUID vs. INT (disregarding natural keys).

1. For a non-replicated, non-clustered database, a clustered INT PK will most often be the better choice, giving performance and smaller data file sizes.

2. For a replicated, clustered, or otherwise distributed database where synchronization, data merging, etc is needed, a NON-CLUSTERED GUID PK will grant reliable record uniqueness, providing data integrity and simple data merging and updating.

That's it. Apply this simple fork to each table and you will achieve an acceptable solution for your needs.

One cautionary caveat, however: Look to the future. Maybe you requirements now don't include taking a client system off-line to go remote, then come back and merge changes, but what about in a year or two when you want to release version 2? I can say from personal experience that designing and implementing an upgrade strategy to convert your complex INT-based database to be GUID-based to support the data merge is no trivial task.

# re: Interesting article about SOA.

Thursday, October 25, 2007 11:36 AM by Marc Jacobi

I dont think it really matters to BizTalk if a message represents a document or an event. I think it's more a question of what the architect chooses.

Personally I could see a blend of the two in a single architecture. Sometimes an event is more natural (when you more interested in the event than in the actual data). But I usually tend to think in terms of messages are documents (an Invoice for example)...

Patrick, I guess you learned your lesson the hard way. The easier way would have been to do some research on TK first, but at least you learned.

The reason the new TKs are not the same as the old, illegal, braindumps that they've been putting out, is because of the recent lawsuit between Microsoft and TK. TK is (poorly) trying to write their own practice test materials now and they're finding that they suck at it. I guess you have too.

Good luck on your future exams!! Pray that you're not one of the future decertified statistics.

# re: The truth about Dynamic SQL and Stored Procedures....

Monday, January 07, 2008 8:35 PM by Dennis van der Stelt

If you can optimize/tune stored procs, you can optimize dynamic sql. Simple.

Same goes for LINQ to SQL or other O/RM, you must optimize everything. And choose the correct technology to solve problems. LINQ to SQL or other O/RM help you solve problems by making them easier. If you need complete control over performance, use a stored proc.

I've seen stored procs of thousands of lines. Tell me, how are you going to optimize that?

# re: The truth about Dynamic SQL and Stored Procedures....

Monday, January 07, 2008 9:16 PM by Patrick Wellink

I have build stored procs of hundreds of lines. This sproc came instead of a sproc of a couple of lines. (The programmers never thought it would get slow) but in time the database grows, and finally they end up with a menu that's just tooooo slow.

This was for the Main menu of I-Mode. So when the simple query didn't work within the specified time frame, it was very simple to rewrite the query and use some logic to speed it up.

So then we ended up with a versiopn 1200 times faster then the original.

This kind of tuning simply cannot be done via dynamic sql. (Sure, you could rewrite the query and compile the dll and deploy that. but that has way more impacht then changing a sproc)

Don't get me wrong, I am not against Dynamic SQL. But I aint against SPROC's eiter.

And you hit a very good point in your comments. You must Optimize them both.....

But who would you trust more to deliver performant code. A programmer or a DBA ? personally I would think a DBA would deliver more performant databases.

And finally dennis, I wont say a sproc of thousands of lines is all that well either. But maybe there was a very valid reason for doing it, or maybe there wasn't one.

# re: The truth about Dynamic SQL and Stored Procedures....

Monday, January 07, 2008 10:35 PM by Chilberto

An important factor in this discussion should be what is being built. A lot of smaller systems do not require the overhead of stored procedures and would probably benefit from a more "fluid" development environment.

From my standpoint, I prefer stored procedures for business applications that will involve more than one developer over its lifetime. They tend to be easier to maintain, analyze and tune.

# re: The truth about Dynamic SQL and Stored Procedures....

Tuesday, January 08, 2008 8:03 AM by Dennis van der Stelt

Patrick, there's not a good reason to have thousands of lines of code in a single method, and there isn't one to have them in your sproc. But still people do so.

Of course this isn't about that you can never use stored procedures. Because sometimes, you can handle large amounts of data in them much more effeciently than via code. Because that's what SQL Server or Oracle do best. If you need performance, do it at the source.

But my problem with stored procedures is that so many times I come across them when there's so much business logic in them. And they're still harder to debug than regular code. People should use stored procedures for retrieving and changing data. Not for business rules or all other kinds of stuff...

# re: The truth about Dynamic SQL and Stored Procedures....

Tuesday, January 08, 2008 8:44 AM by Patrick Wellink

I understand your point but I have seen bad Dynamic SQl as well...

But your statement :

you can handle large amounts of data in them much more effeciently than via code. Because that's what SQL Server or Oracle do best. If you need performance, do it at the source.

I totally agree with you at this point. But this implies that you have yo implement some logic in SQL.

You sould always consider where you put stuff. For simple selects and updates it's ok to use dynamic SQL. But as soon as the words 'Large amounts of data' are uttered you should consider switching to Sproc's. Unfortunately this also means you have to implement part of the Business logic in SQL as well.

"It's logical that copying the entire context from one request message to a response message can cause these problems"

Can you elaborate on that?

Im having those issues described. But I dont quite understand how not copying the context will make this work. When copying the context, you are copying the correlation values used by BizTalk to futherly route the response message. If this is not present in context, how are message correlation values assigned to the new context?

Well for example....

all those values are beeing copied. So if BT wants to delete a specific message, we will have TWO of those instead of one.

If you want to correlate on properties make sure the property you correlate on is a promoted field. Define a propertyschema and use a xmlreceive pipeline to populate all the required properties.

# re: About EDI / Property Schemas and Validate instance

Friday, June 12, 2009 12:43 PM by Patrick Wellink

No Sorry, this code is no longer available.

Although the solution worked quite well it still used sequential convoys. And using sequential convoys in a orchestrations will make them slow if has to handle too many messages. The state of the orchestration is persisted for every loop. So, 10 loops go fine, 100 loops tak ea little longer and with 1000 loops, the system is only persisting state and flodding the DB with it.

This was not a problem of my solution but is a problem of sequential convoys. Since my solution used seq convoys it also suffers from this problem. Making it not as robust as it should be.

The only way I kan think of to limit instances is by using a database.... Sorry

No in WCF there are two context properties, inboundheaders and Outbound headers. (I Believe.. google and you will find them). Those context properties contain an instance of a XML document with all the headers. So it would be as simple as get that context, write to an xml document, and then import that as a schema.

# re: Getting rid of : WCF-Custom" raised an error message. Details "System.Data.SqlClient.SqlException: Timeout expired

Thursday, December 23, 2010 9:47 AM by Patrick Wellink

Well dennis i agree partly..

Yes they are the same. So one could be deleted.

But this is only a query to see if there is data. If there is data the second will kick in and get the data for me.

So it's not very important if the first query sees data that's not yet there. The second will fix that for me.

I have 8 processes executing this sproc every second. Any transaction level other than Uncommitted will give serious concurrency issues.

I know 8 doesn't seem much, but when you start a receive port in BizTalk, All the receive locations (4 in my case) will start at exactly the same time. And that for every host (2 in my case). So you will have 8 concurrent calls to the database.

This will very often cause deadlock situations and then all the receive locations will shut down. So Effectively BizTalk is not receiving any data anymore.

Everything should be better with the new WCF- Adapter but it isn't unfortunately i had to fall back on the NOLOCK hint and a pre select to see igf there is any data to make everything work.

Too bad MS did such a poor job on the WCF SQL adapter for BizTalk. (This is not the only issue I have with the WCF adapter).

Bottom line is, The higher the transaction level, the lower the concurrency. I need very high concurrency. The faulty behaviour of the WCF SQL adapter (holding a lock on the table causing deadlocks when there is no data) is basically why it's done like this. You can see the initial setup to see what the original idea was. Unfortunately this will not work. So i had to resort to the second setup.

It's not the best solution ever, but it's a workaround.

Thanks kiran, i agree with you, but we cannot use the serializable transaction level that comes with 'Use Ambient Transaction' due to the high concurrency of the database....

Remember polling is done by 4 receive locations and we have 2 BizTalk hosts doing receive.

Well there is no such thing as an appliction on the message itself.

You could do some logic on receivelocation name and the see to what application it belongs.

Or you could stamp it on the context yourself there are loads of samples out there how to create a pipeline that does just that. Then you just configure that pipeline component in the receive location and the application name will be available on the context of the message.

hi patrick. can you give me the Management stuff that you are saying. This would be a great help for us. We just need the application name of the suspended messages from BizTalk.

thanks ahead.

# re: Failed message routing in BizTalk 2006 REALLY NICE !!!!

Friday, January 21, 2011 11:36 AM by ylo

We have created a windows service to get the BizTalk suspended messages and post it to the the ESB portal. This service subscribes to WMI Suspended events and WMI Message Instance without consuming the suspended message in the BizTalk Suspended queue. It extracts the metada/context of the suspended message as well as the fault details then logs them to ESB Portal using ESB 2.0 Framework API. We were able to log most of the context as well as some of the fault details to ESB although we are having issues left for getting the data from BizTalk for the following.

Fault Details Exception Details

Fault Code: Stack Trace:

Fault Description: Inner Exception Message

Failure Category: Source:

Fault Severity: Type:

Exception Type: Target Site

Error Type:

Application:

Application Scope:

Fault Generator:

Service Name:

From this list, the critical information for us to get is the “Application Name”. We tried using WMI on this but when we checked the available WMI classes, they do not have any method/object that would provide us these info.

Have a look at http://biztalkom.codeplex.com/

I think there should be a way to get all applications, then get all the receive ports and next get all the receivelocations.

Put that in a cached dictionary and you should be able to match the app to the receivelocation..

Another way would be to put all the receive locations in the Business rule engine and let the business rule engine decide to what app a message belongs. ( would be a nice & fast & easy solution)

# re: xs:int and xs:integer, what's the difference....

Tuesday, February 08, 2011 1:03 PM by Carlo

Hé Patrick,

the behavior is expected as the int in XML is limited to 32-bits numbers while the integer in XML is unlimited in the numbers it might contain. So, use int when the numbers you communicate are always within the boundaries of 32 bits and consider integer otherwise.

Carlo

Hi Patrick.

Whoa!. I never realized this. Good to know. This is a good wake-up info, and keep this in mind.

# re: xs:int and xs:integer, what's the difference....

Tuesday, February 08, 2011 3:58 PM by Dan

Hi Patrick,

The definitions for xs:int and xs:integer can be found in the documentation of W3C XML Schema, such as the following:

www.tech-know-ware.com/.../xsd-overview.html

Basically, they recommend avoiding the use of types like xs:integer in schemas intended for binding tools.

# re: xs:int and xs:integer, what's the difference....

Thursday, February 10, 2011 8:13 AM by Patrick Wellink

@Carlo,

I knew there was a diference, but i did not expect the xs:integer to show up in code as a string.....

# re: xs:int and xs:integer, what's the difference....

Thursday, February 17, 2011 12:00 PM by Marc Weber

Hi Patrick,

I did encounter that behavior once before. And it actually correct by the w3C definition

byte -> A signed 8-bit integer

decimal -> A decimal value

int -> A signed 32-bit integer

integer -> An integer value

long -> A signed 64-bit integer

# re: xs:int and xs:integer, what's the difference....

Thursday, February 17, 2011 4:20 PM by Patrick Wellink

I know they were different, but i was surpised to see the 'integer' turn up as a string in intellisense when I used the webref I had in the client project.

That's what surprised me. Not that they were different but to see a integer (you would expect some number) reflected as a string.

# re: Getting a copy of a DLL that's only in the GAC

Thursday, March 10, 2011 9:56 AM by Harpreet

Hi ,We can even copy the dll from gac by going through the windows explorer .But in this case you need to go to "C:\WINDOWS\assembly\temp" and then can move one step back where you would find the folder many folders but "GAC_MSIL" is the one which contains all the folder for all the dll in gac .You can explore further to get the required dll [ Eg : (Microsoft.BizTalk.Streaming\3.0.1.0__31bf3856ad364e35) to get the Microsoft.BizTalk.Streaming.dll .

# re: Removing unwanted namespaces from a BizTalk Map

Saturday, April 02, 2011 10:55 AM by Fernando Pires

Hi Patrick

Here is another solution using a streaming approch! You would need to do this in a pipelinecomponent but as it is uses a streaming approch there should not be a performance issue.

1) First reference the Microsoft.BizTalk.Streaming dll

2) Second create the class bellow

using

Microsoft.BizTalk.Streaming;

using

System.IO;

using

System.Xml;

namespace

TestXmlFiles

{

public class XmlNamespaceRemoverStream :

XmlTranslatorStream

{

protected override void TranslateStartElement(

string prefix, string localName, string nsURI)

{

base.TranslateStartElement(null, localName, null);

}

protected override void TranslateAttribute()

{

if (this.m_reader.Prefix != "xmlns")

base.TranslateAttribute();

}

protected override void TranslateXmlDeclaration(string target, string value)

{

//This makes sure that the XmlDeclaration if any is not removed

this.m_writer.WriteProcessingInstruction(this.m_reader.Name, this.m_reader.Value);

}

public XmlNamespaceRemoverStream(Stream input)

: base(new XmlTextReader(input), Encoding.Default)

{ }

}

3) Third call it from your pipeline component.

public IBaseMessage Execute(IPipelineContext pContext, IBaseMessage

pInMsg)

{

IBaseMessagePart bodyPart = pInMsg.BodyPart;

Stream originalStream = bodyPart.GetOriginalDataStream();

if (originalStream != null)

{

XmlNamespaceRemoverStream rmstr = new XmlNamespaceRemoverStream(originalStream);

pInMsg.BodyPart.Data = rmstr;

}

return pInMsg

}

Wednesday, April 13, 2011 4:21 PM by Patrick Wellink

Yes, i know, But i needed to execute the map anyway, and by doing it this way, no extra coding is needed, and no extra processing is needed. All is done after the map is finished.

# The BizTalk No Output Producing Endpoint Adapter !!!!

Wednesday, April 20, 2011 3:13 PM by Ric Pullen

We used this extensively to destroy the 1000+ ACKs we received from our pathology system every day.

We are now moving to 2009 (64bit) and we require the same functionality. Are you able to share the source code? GotDotNet no longer exists and I was unable to find it on CodePlex.

or just some pointers on how you developed it would be useful. Hope you still get to see messages from posts this far back.

# re: Getting a copy of a DLL that's only in the GAC

Friday, November 18, 2011 10:24 PM by randy k

You can also do this the "exporer" way..

Must be done from a "Run" box:

Type in "c:\windows\assembly\gac_msil"

This will open the GAC in a reguarl window allowing you to see the underlying dll's
