26 Biztalk Bam Questions And Answers

5⟩ Please explain what is correlation?

An Orchestration can have more than one instance running simultaneously. Even though each of those multiple instances perform the same action, it does it on different data contained within a message. Correlation is a process of associating an incoming message with the appropriate instance of an orchestration. For Example: If your orchestration issues a purchase order, receives an invoice, and sends a payment, the developer must make certain that the invoice message is received by the orchestration instance which corresponds to the orchestration that sent the Purchase Order. Without correlation, it would be possible to send out an invoice for thousands of items even though the purchase order is for one. And each correlation is based on a set of properties known as correlation types


6⟩ Tell us what is the dfference between Real Time Aggregation and Scheduled Aggregations used in BAM?

The storage of RTA is a SQL table and the aggregation is updated and maintained by SQL trigger. The event importing and aggregation update are completed in the same transaction, therefore its data latency is negligible and almost real-time. The scheduled aggregation is saved in Olap cubes which need to be processed periodically by the cubing DTS package


8⟩ Explain me what is Activity Relationship?

An activity relationship exists when an activity relates to one or more other activities. An example of this is having multiple Shipment activities related to a single Purchase Order activity, or one Shipment activity containing items from two Purchase Order activities.

To indicate that two activities are related, you need to know both names and have the corresponding ActivityIDs in memory in order to call AddRelatedActivity. This API creates the link between the corresponding activity records.


9⟩ What is rehydration?

When a message is received, or else when a timeout has expired, the orchestration engine can be automatically triggered to rehydrate the instance – it is at this point that the orchestration engine loads the saved instance of the orchestration into memory, restores the state, and runs its from the point it left off.


10⟩ Explain me what is BAM and whats the benefits of using it?

Business Activity Monitoring (BAM) is used to monitor business milestones and key metrics in near real-time throughout a process in BizTalk. Business Activity Monitoring (BAM) is a module in BizTalk that captures business data and process milestones to allows business decision makers to gain insight of their in-flight processes. Using BI tools to derive up-to-date metrics and key performance indicators from the BAM databases, users can forecast process trends and monitor processes in real-time. BAM also provides a mechanism to alert users to situations that require their intervention to prevent undesirable outcome or to encourage a beneficial result.


11⟩ Explain how do you call a Non-Serializable .Net helper class inside an Expression Shape?

Add a reference of that dll (class). The class must be strongly signed and in the GAC.

Make sure your transaction type of Orchestration is Long Running transactional.

Add an Atomic scope.

Create an Orchestration variable of that class inside the scope.

Create an instance on that object inside the scope.

Call the method


13⟩ Tell me what is this tool BM.EXE and why do I need it?

BAM Management utility or “bm.exe” provides for end-to-end management and deployment of BAM. You can use the BAM utility to perform the following tasks:

☛ Consume BAM definition and BAM configuration XML as input.

☛ Deploy the run-time infrastructure on the server, which includes the BAM Primary Import database, BAM Star Schema database, BAM Analysis database, and corresponding Data Transformation Services (DTS) packages.


15⟩ Tell me what is an Activity and an Alert?

BAM Activities identify the milestones and tracking data an individual is interested in tracking. Milestones are the steps in an activity that are measured in time, and tracking data are the key data points in a process you are interested in tracking (such as a customer ID or name).

18⟩ Explain me what are various event streams used in BAM API?

☛ Orchestration Event Stream (OES)

Asynchronous, participates in BizTalk orchestration transactions.

☛ Buffered Event Stream (BES)

Asynchronous, high throughput, some latency.

☛ Direct Event Stream (DES)

Synchronous, no latency and directly written to the BamPrimaryImportDb.

☛ Messaging Event Stream (MES)

Asynchronous, participates in BizTalk Server pipeline transactions.


19⟩ Tell me what are the various types of BAM Interceptors available?

The BAM Interceptor is an object that lets you instrument your application to capture data of interest.

☛ BAM WCF interceptor: BAM can capture data from SOAP envelope in a WCF request, response or fault message. The data is specified using interceptor configuration (IC) file (XML file created by developer). The service’s app.config must be modified to load the BAM components at runtime.

☛ BAM WF interceptor: like WCF Services, BAM can also capture milestones from WF Activities. Am IC file is used to specify the data that must be captured. BAM components must also be loaded at runtime.
