Does orchestration support parallel activation?

Submitted by Anonymous on Sat, 07/19/2008 - 01:46.

Does orchestration support parallel activation?

Yes Orchestration does support parallel activation under the following conditions:

1. If a particular correlation is initialized on more than one task of a parallel activation by a Receive shape, each of the concerned activating Receive shapes must initialize exactly the same correlation.

2. If one of the tasks of a parallel activation has an activatable Receive as the first shape, all of the tasks of that parallel activation must have an activatable Receive as the first shape, and all of those Receive shapes must initialize at least one correlation.

Types of Transaction in Biztalk

Submitted by Anonymous on Thu, 07/17/2008 - 20:30.

Q What are the types of transaction in Biztalk?
A. Atomic Transaction and Long-Running Transaction

What is Correlation? Why do we need it?

Submitted by Anonymous on Thu, 07/17/2008 - 14:44.

84. Q. What is Correlation? Why do we need it?
A. 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.

Biztalk Orchestrations: Dehydration and Rehydration

Submitted by Anonymous on Thu, 07/17/2008 - 14:02.

Dehydration:
When an orchestration has been idle for a while, the orchestration engine will save the state information of the instance and free up memory resources.

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.

ans to some questions

Submitted by Anonymous on Wed, 07/16/2008 - 14:00.

# How do you call a Non-Serializable .Net helper class inside an Expression Shape?
Ans :create a variable of the class inside the atomic scope in the orchestration view explorer and use this variable inside atomic scope

# How do you use Auto Mapping in the BizTalk 2004 mapper?
ans :press the shift key and drag the root node of source to destination

# What does the Value Mapping Functoid do?
Ans: this functoid is used to send the second parameter as the output if the first parameter value is true
# What is the default mapping for Auto Mapping?
Ans:Structure
# What is a Message Type (i.e. BTS.MessageType) and how is it used in BizTalk?
Ans:Mesage type is the combination of the namespace and the root node
What is the difference between a Document Schema and a Property Schema?
Property schema consists of the elements of the document schema which has been promoted
What is the difference between static, dynamic and direct binding?
static binding specifies particular port address ;
dynamic gives address of the port at runtime
direct binding sends messages to messagebox

What is property promotion, why is it required?

Submitted by Anonymous on Wed, 07/16/2008 - 02:03.

Q 17 What is property promotion, why is it required?

A. Biztalk provides you with a really smart routing feature that allows the engine to decide where to send which message. For example, If you receive a message with the EmployeePaySlip schema, and it has the approved flag to true, it should be redirected to the Finance system Orchestration for making the payments and to the HR system Orchestration for keeping the records. This built in intelligence for the Biztalk engine allows it to route the messages simply based on some content within the messages.

In order to achieve this, the Biztalk engine obviously needs to understand the fields based on which the routing decisions can be taken. To simplify and optimize this working, Biztalk has introduced the notion of "promoted properties". The Biztalk engine can get easy access to the promoted properties without knowing the entire message and hence it can save loads of time and complexity when dealing with routing. To route a message, the Biztalk engine simply reads its promoted properties and does not care about other contents in the message.
