15. Select the class to complete configuring the custom fact retriever. 16. After creating the custom fact retriever to retrieve the DataConnection and configuring the policy to use the custom fact retriever, it is time to define the rules. So, define the business rule to compare the requested service address with the customer addresses already in the Northwind database. If there is a match, the service request will be scheduled. 17. Deploy the rules and invoke them from an orchestration, specifying the XML messages that the policy expects. The rules engine will invoke the UpdateFacts method of the custom fact retriever. The method will add a DataConnection fact to the Northwind database to the rules engine facts.

The rules engine examines facts provided either directly from an orchestration or from a custom fact retriever. The facts provided directly from an orchestration are called short-term facts, and the

orchestration supplies them each time BizTalk invokes the rules engine. The facts provided from a custom fact retriever are called long-term facts, and they can be reused each time BizTalk invokes the rules engine. A BizTalk orchestration can also treat the DataConnection in this example as a short-term fact. Accomplish this by creating a DataConnection in an Expression shape and including it as a parameter to the Call Rules shape. However, each orchestration instance would create its own DataConnection. You can improve the scalability and performance of the application by treating the DataConnection as a longterm fact and sharing it each time BizTalk invokes the rules engine. In general, treating a fact as long-term is preferable under the following conditions: The fact value can be shared each time BizTalk invokes the rules engine. Retrieving the fact incurs a significant performance penalty. Caching the fact value will still allow the rules to execute correctly. The fact is not directly available in the orchestration that invokes the rules.

The rules engine invokes the custom fact retriever s UpdateFacts method each time the policy executes. This method decides when to update the facts. In this example, the UpdateFacts method examines the factsHandleIn parameter to check whether the DataConnection was already created. If the factsHandleIn parameter is null, the method creates the DataConnection, inserts it into the rules engine, and completes by returning the DataConnection object. The next time the rules engine invokes the method, the rules engine includes the object returned by the method in the factsHandleIn parameter. If the factsHandleIn parameter is not null, the method knows that it has already inserted the DataConnection into the rules engine, and it simply returns the same object. Although this solution example uses a simple algorithm to decide when the long-term fact needs updating, the developer can implement a more sophisticated approach. For example, the developer could refresh the facts every hour by returning a DateTime object when the facts are refreshed and decide to update facts by comparing the last refresh time to the current time.

There is one interesting and useful variation on how you can hold references to objects that you ll want to know about: auto_handle, which is used for managed types that you want treated like automatic variables that are not created in the function, but rather come from the result of a function call.

You are building a solution that must execute business rules based on dynamic information. These business rules are likely to change over time, and you want to minimize the impact on the solution when modifications are needed. To do this, you want to be able to call the rules engine from a .NET assembly.

Note The problem within this recipe is the same as in Recipe 7 7. The solutions in the two recipes differ in how
