66 Biztalk Adapter Questions And Answers

2⟩ Explain me how to route binary data?

To route binary data you can use pass-through pipelines on the receive location and send port. BizTalk will route (copy) the data from the source (receive location) to the destination (send port). If you want to route the binary data based on some information in the binary data then you write a custom Disassembler to promote the properties you need from the incoming message to route the binary data.


3⟩ Tell us what are Host and Host Instance? Did you deploy BizTalk more than one machine?

Host is nothing but the logical container of host instance. from which we can create host instance. Host instance is a Win-NT service.

A BizTalk Server Host is a logical set of zero or more BizTalk Server run-time processes in which you deploy items such as adapter handlers, receive locations (including pipelines), and orchestrations.

A host instance is the process where the message processing, receiving, and transmitting occurs You install a host instance on each server running BizTalk Server 2006 that has one or more hosts mapped to that server.


6⟩ What are persistence Points?

☛ The process of saving your running orchestration state at certain point is called persistence.

☛ Orchestration engine persist a running instance which is based on the design of orchestration.

☛ There are few events or stages, which triggers the persistence operation called persistence points.


7⟩ What is content-based Routing?

Content-based routing provides flexibility for users who want to route messages based on envelope properties or on receive port configuration properties. Routing can be performed based on information contained in the envelope of the document or even configuration information from the receive location.

A BizTalk Server business process involves receiving, processing, and sending messages. Some messages do not require intensive processing in an orchestration. They can benefit from a simpler and more efficient solution called Content-based routing.


10⟩ Explain me what you mean with Native Adapters and Custom Adapters?

☛ Native adapters are those that are shipped with the product and there are more than 25 multi-platform adapters.

☛ But in some cases a BizTalk Server may need to transport messages to a specific custom application or use a protocol for which a native adapter does not exist.

☛ If you are unable to locate an adapter to support your communication requirements, BizTalk Server provides a framework for developers so that you can develop your own custom adapter.


11⟩ Do you know how To Use The Message Types?

☛ Right-click Messages in the Orchestration View tab to create a new message, you have four choices for the Message Type property.

☛ Expand Multi-part Message Types and then choose Create New Multi-part Message Type.

☛ Name your multi-part message type then expand it so you can see its Message-part_1 member (Biz-talk suggested name)

☛ Set the Message Body Part property to True so that it acts just like a regular message.


12⟩ Explain me what Is Biztalk Business Process Configuration?

Information worker can set parameters for an orchestration that implements a business process, which a business analyst may not be able to create.

Developer creating an orchestration can define parameters for an orchestration to enable information workers configure it. An information worker sets those parameters using the TPM service by specifying their values in the partner’s agreement


13⟩ Do you know what is a link in a Map?

A link specifies the basic function of copying data from an element or attribute in an input instance message to an element or attribute in an output instance. You create links between records and fields in the source and destination schemas at design time. This drives the creation, at run time, of an output instance message conforming to the destination schema from an input instance message conforming to the source schema.


15⟩ Do you know how Rules Engine Is Provided In Biztalk Server?

Rules engine is provided as component of a business rules management system, which provides the abilities such as define, register, classify and manage all rules, verifies consistency of rules definitions, defining relationships among rules and relates them to IT applications which are effected by one or more rules.


16⟩ Do you know what is an Adapter Handler?

☛ An adapter handler is an instance of a BizTalk host in which the adapter code runs.

☛ When you specify a send or receive handler for an adapter you are specifying which host instance the adapter code will run in the context of.

☛ An adapter handler is responsible for executing the adapter and contains properties for a specific instance of an adapter.

☛ A default BizTalk Server configuration will create adapter handlers for all of the installed adapters, but you may want to create additional adapter handlers for purposes of load balancing or to provide process isolation for a particular adapter handler.


17⟩ Explain me why do we need convoy?

When a group of correlated messages could potentially be received at the same time, a race condition could occur in which a correlation set in a particular orchestration instance must be initialized by one of the messages before the other messages can be correlated to that orchestration instance. To ensure that all of the correlated messages will be received by the same orchestration instance, BizTalk detects the potential for such a race condition and treats these messages as a convoy.

Convoy is a term which we use to describe a class of application protocols, specifically it is a set of application protocols which have a race condition as described above. Let’s take an example. Say you are a hospital and want to have a service which handles all information about each patient. For a given patient you have three types of messages, an admittance message, status messages, and a discharge message. If you look at your protocol, you will have built a service which just receives. Now let’s think about what could happen. Let’s say you send the patient admittance message and it goes through the system using maybe a synchronous protocol like HTTP. That means when you get the 202 back, you know the message has been delivered. But what if the BizTalkServer host which is actually supposed to process the message hasn’t started yet (ie the nt service is stopped). Maybe you had a power outage, maybe some intern decided to “hit this button”, who knows. So the orchestration instance which is supposed to handle all messages for patient X has not physically started. The message is in the database (MessageBox) and if you look in HAT you will see the orchestration is marked as ready to run, but it can’t start cause there is no where for it to start.


18⟩ Do you know what is an Adapter?

☛ An adapter is a software component (COM or .NET-based) that enables you to easily send messages out of or receive messages in BizTalk Server with a delivery mechanism that conforms to a commonly recognized standard, such as SMTP, POP3, FTP, or Microsoft Message Queuing (MSMQ).

☛ As Microsoft BizTalk Server has evolved, the need for adapters that quickly enable connectivity with commonly used applications and technologies has increased.

☛ BizTalk Includes over 25 multi-platform adapters that simplify the integration with Line of Business (LOB) Applications (such as Siebel, SAP, JD Edwards, Oracle, and Dynamics CRM), database (Microsoft SQL Server, Oracle, DB2) and other technologies (Tibco, Java EE).


19⟩ Explain me what are the native adapters in BizTalk?

"Native" or "integrated" adapters in BizTalk are: FILE, FTP, HTTP, MQSeries, MSMQ, POP3, SMTP, SOAP, Windows Sharepoint Services, and the seven WCF adapters (WCF-WSHttp, WCF-BasicHttp, WCF-NetTcp, WCF-NetMsmq, WCF-NetNamedPipe, WCF-Custom, and WCF-CustomIsolated)


20⟩ Explain me which Interfaces do you need to implement in a disassembling custom pipeline component?

A disassembling pipeline component receives one message on input and produces zero or more messages on output. Disassembling components are used to split interchanges of messages into individual documents. Disassembler components must implement the following interfaces:

☛ IBaseComponent.

☛ IDisassemblerComponent.

☛ IComponentUI.

☛ IPersistPropertyBag.
