Biztalk Bam Interview Questions And Answers

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).

A BAM view is a representation of the milestones and business data tracked in one or more activities on the BAM Portal.

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.

Yes. There are some shapes like:
☛ Terminate
☛ Throw Exception
☛ Group
☛ Loop
☛ Message Assignment
☛ Suspend
☛ Transform

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

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.

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.

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.

The most commonly data sources used with BAM are:
☛ BizTalk Application
☛ BAM API
☛ WCF Services (WCF Interceptor)
☛ WF Workflows (WF Interceptor)

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

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

Both are same and terminology is used interchangeably.

BAM collects raw tracking data from the BAMPrimaryImport (BAM Primary Import) Database.

No, Because the code execution for retry happens in adapter which is out of the BAM tracking scope.

Yes its possible with a condition that BAM server has to be part of the BizTalk group.

TPE can't be used here as it can only be used to capture data from BizTalk artifacts, thus BAM API have to be used.

Yes its possible to have multiple views on single Activity.

The Run-Time Rule Engine performs the following functions:

☛ Processes rules created as declarative statements without procedural instructions
☛ Groups all the rules that apply to a business process together (a policy) without having to arrange them in order of, or define them in terms of, relationships, contingencies, or dependencies
☛ Resolves rule conflicts arising from the simultaneous presence of multiple facts and conditions
☛ Supports forward chaining of rules that involves reevaluating rules in the executing policy based on changes to the fact base (addition/removal of facts or changes in state/data of existing facts). Forward chaining does not inherently span policies

Tracking Data Decode Service or TDDS, is a service that moves event data from the MessageBox database to the BAM Primary Import database. This service processes and persists both Business intelligence and BizTalk Health Monitoring data.

That depends on the functionalities (features) you want to install, but for me the correct answer is no.

It is a Web-based feature that consists of a collection of ASP.NET pages, it portal provides real-time, end-to-end visibility into a business process.

Continuation is the ability to contribute to a single BAM activity from different applications by using two different unique identifiers as the ActivityID. For example, in one part of a business process, a customer’s PO number might be used to track an activity. In another part of the process, an internal order fulfillment number might be used to track the same activity. You could enable continuation and relate the PO number and the order fulfillment number, so that both parts of the process could add information to the same activity.
