BizTalk Rule Engine

151 of 184 | MS-BRE: Here are the results for my port of Peter Lin`s tests - For those following the debate on the implementation of the Rete algorithmin the Microsoft Business Rules Engine, you may be aware that I undertook to port some CLIPS/Jess tests provided by Peter Lin to the MS-BRE and to publish the results. This follows on from the original article I published here. My results for the ported tests are documented here. They show virtually identical scaling behaviour between Jess and the MS-BRE....

152 of 184 | BizTalk Server 2004: The great MS Business Rule Engine Debate - I have had some fun in the last couple of weeks debating the Microsoft Rules Engine with Peter Lin.   Many people in the BizTalk community will know that Peter used Amazon and The ServerSide site early this year to launch an attack on Microsoft`s representation of their rules engine.  You can read the original thread here.  Based on a BizTalk performance whitepaper, the latest version of which is here, and on the documentation of the Rules Engine on MSDN, he deduced that that the engine does not implement the Rete algorithm correctly, does not support forward chaining inferencing and does not scale.   For the uninitiated reader, the Rete (Latin for `Net`, pronounced "Ray-tee" according to m......

155 of 184 | BizTalk -> More on Constructing Messages and Configuration Information for an Orchestration - I recently was reading Scott`s entry on Constructing Messages from Scratch with Embedded Resources. This is a good method, so take a look a look at it HERE. Below is a variant on Constructing Messages in an Orchestration. This also can be used as a method to read any type of configuration information into an Orchestration.This method needs: 1) A Sql Server table to store the templates for the XML Messages and/or Configuration Information.2) A BizTalk XML Schema.3) A BizTalk Map. A Sql Server TableBelow is a create statement for the table with three columns: if exists (select * from dbo.sysobjects where id = object_id(N`[GenericCodes]`) and OBJECTPROPERTY(id, N`IsUserTable`) = 1)drop table [......

156 of 184 | It`s all about semantics, frankly - IBM Research came up with something very interesting approach to finally incorporate semantics better into the whole Web Services story: Semantic Tools for Web Services. Definitely worth a look. Semantic Tools for Web Services Semantic Tools for Web Services is a set of Eclipse plug-ins that allow developers to insert into a WSDL document semantic annotations (references to concepts in a semantic model) that describe the semantics of the input, output, preconditions, and effects of service operations. A second plug-in matches the description of the service or composition of services to that for which a developer is searching. This semantic matching and composition of Web services, develope......

Last week Richard Seroter and I tried to to kill about 60 people by putting them through the extended 5 day MOC course.  What does that mean   14 to 16 hours a day for 5 days, first going through the the typical 5 day MOC (Microsoft Official Curriculum) lab training (this w......

160 of 184 | Changing a VPC Computer Name with BizTalk - Im looking at using Virtual PC with a team of BizTalk developers. The idea is to install the dev env (Server 2003, SQL Server, Visual Studio, BizTalk etc) on a virtual PC image, and then each team member uses a copy of the image to develop with. We have network problems if two or more images with the same computer name are started with network access (to SourceSafe). So I attempted to change the computer name in an image. After a while I managed to do it like this: Export any information from the BizTalk databases (business rules etc.)Run ConfigFramework /uDelete BizTalk jobs in SQL Server AgentDelete BizTalk logons in SQL Server SecurityDelete BizTalk databasesChange computer nameRe-start ......

That day always left me with the feeling that you could do really cool things with that, but not a single occassion last year allowed me to put this engine to test. Now Microsoft published an interesting article about complex business rule processing up on MSDN. That`s the kind of rules I thought about. Haven`t got the time to test it though....

169 of 184 | Making Spaghetti with BizTalk - Last week I went out to assist a client that needed some BizTalk help.  This sounded pretty harmless and from the overview of the system, the job of BizTalk was to accept a request, perform some transformations, validate that certain fields were populated and then communicate with a back end system.  For this type of scenario, a fantastic place to use BizTalk! I was a little surprised at what I found.  An initial map with 357 functoids and an Orchestration with 44 Sends, 28 Receives, 24 Transformations, 9 Decisions, 2 Loops, 2 Calls to the Business Rules Engine, 8 Request/Response Ports and 10 Request Ports.....wow!  I wasn`t real sure that I could find spaghetti code in a BizTalk Orchestra......

Depending on your scenario, the issue can cause a significant performance degradation on the receive side, the CPU utilization is pegged at close to 100% but the inbound processing rate is very slow.   The issue is caused by some of the QFE`s for the Rule Engine and possibly even the A4Swift accelerator, to be honest I don`t want to waste time digging thru the dependencies and which QFE cause it.

184 of 184 | EBZ213: David Chappell on services, business processes and BizTalk 2004 - David Chappell presented a barn-storming presentation based on the idea that the future is services, that services will be called by business processes and that we need to look for a platform that will manage business processes.  He argues, convincingly that we can't expect App Servers to perform this role.  The answer comes with Business Process Platforms.  Here he positions BizTalk 2004 as the answer and goes so far as to claim that it will be the major product at future TechEd's and that getting close to business processes (through BizTalk) could be a key part of keeping your job as a developer since business processes are much harder to outsource ......
