☛ he BizTalk Adapter Framework offers a stable, open mechanism for all adapters to implement or access work from the BizTalk Server Messaging Engine.
☛ The interfaces described in the Microsoft.BizTalk.Adapter.Framework namespace enable adapters to provide a means to modify configuration property pages.
☛ It also is a means to import services and schemas into the BizTalk project.

When the new host is created it results in a new entry in the Host table in the Management database and also a new Host queue in the MessageBox.

A pipe line is used to write Distinguished Fields in the message context when a message is received on a port. Dis-assembler pipeline component such as XML and flat file disassemble does the job of writing the message context by the pipeline. In addition to it, custom pipeline component could also be performing it.

MessageBox_Message_ManageRefCountLog_BizTalkMsgBoxDb is the job which runs continuously in spite of scheduled to run once per minute.

☛ Store all messages and context received.
☛ Stores all subscriptions.
☛ Stores all Host Queues.

☛ By using content based routing, files can be transferred.
☛ By creating receive port and send port. If send port is configuring, provide the condition as BTS.
☛ Receiveportname= <receive_portname created>

Following is the list of events (Persistence Points) that call the persistence operation:

☛ Orchestration Instance is suspended or finished
☛ System shutdowns in a controlled manner
☛ Engine determines it wants to dehydrate
☛ Atomic or long running transactional scope ends
☛ At debugging breakpoints
☛ Execution of other orchestrations through the Start Orchestration shape
☛ At the Send shape (but not atomic)

When A message is passed through biztalk without being processed then it is called Message Routing. When A message is passed based on certain field value of schema, it is called content routing.

Messages in BizTalk are data, and each message must be of a selected message type. E-mail, Documents, Info-path forms, large binary files, SQL records, flat files, and anything XML can be processed as messages. BizTalk is all about messages and message-oriented programming. The most common message type in Biz-talk is a schema.

Information workers Manage trading partner relationships within organizations. Business Activity Services include a Trading Partner Management (TPM) component to allow them do those. TPM database stores information about trading relationships. Information workers can create and modify agreements with trading partners who use BizTalk Server.

There are two ways for upgrading
1.In Place upgrade
2.Transfer Upgrade.

The promotion of Prompted Fields/Properties is done in the message context by a pipeline called receive pipeline at the time when a message is received on a port. This task is performed by dis-assembler pipeline component (XML or a flat file dis-assembler). In addition to it, custom pipeline component could also be performing it.

☛ This property defaults to file://{Receive folder value}/{file mask value}.
☛ The literal prefix file:// is required so as to communicate the protocol in use.
☛ It is string from 0 to 255 characters.

Sending messages from one orchestration to another is done by using Direct Binding technique. It is also being used for sending messages directly into the message box. It is used in publish and subscribe system in BizTalk for sending messages among orchestrations.

A rules engine is a software system, which is used for executing one or more business rules in a dynamic production environment. The rules might be from legal regulation, company policies or any other resources.

Purpose of deriving up-to-date metrics and key performance indicators from the BAM databases, Business Integration tools are used.

The forecasting of process trends by uses and monitoring processes in real time scenarios is done by using BI tools. Users get alerts for situations which need their intervention for preventing undesirable outcome for encouraging beneficial results, a mechanism is provided by BAM.

No. The names of the various ports must be unique, not just inside an Application but for the whole BizTalk group.

A message created in BizTalk Orchestration is bound to a schema, this is a typed message. In un-typed messages, the message is bound to System.Xml.XmlDocument instead of a schema.

Single Sign-On database (SSODb) securely stores the configuration information for receive locations, other known secret information is stored in the BizTalkMgmtDb.

BizTalk server detects the potential for certain race conditions, which are ensured that all correlated messages are received by the same orchestration instance. The potentiality of these race conditions is detected by BizTalk server.

These messages are treated as a ‘convoy’. A convoy set is a group of correlation sets. All such subsequent messages which match the general subscription are evaluated against the convoy set, and the matched convoys are routed to an existing port.

Adapters are the components that enable the BizTalk to interface with the external communications protocol.
They mediate between the protocol and the messaging pipeline in use.

Message routing is a method of passing through BizTalk without being processed.

Content routing is a method of passing of the message which is based on certain field value of the schema.

BizTalk enables companies to integrate and manage business processes by exchanging business documents between business applications within or across organizational boundaries.

Monitor BizTalk Server, this job scans the BizTalkMgmtDb, BizTalkMsgBoxDb and BizTalkDTADb database for any known issues, including orphaned instances.

First create a Correlation type and then create an instance of it.
