Biztalk Adapter

We can use webservices where we need to get data from multiple sources in one go. For e.g. getting price quote from 10 different vendors. You make one orchestration and use WS inside it.

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.

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.

Checking the subscription table is the First thing when messages come in MessageBox and a copy of the message is sent to the subscriber.

When we run MSI packages, it will register the application with Windows Operating System and then load any related assemblies in the Global Assembly Cache.

☛ 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.

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.

No. The adapter only writes data in the context of the message which is further interrogated by another component of BizTalk.

The reason for having multiple receive locations inside one Receive port is to have the ability to receive different messages from different locations and having BizTalk treat them as if they were received from the same place and/or had the same message type.

☛ 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.

☛ 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.

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

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.

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.

☛ 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.

"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)

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.
