27 Biztalk Esb Toolkit Questions and Answers:

1 :: Explain me what is ESB Toolkit and why do we need it?

BizTalk ESB Toolkit provides a set of services on top of the existing BizTalk Server 2010 architecture to enable service consumers and service providers to be part of a loosely-coupled but mediated environment. Using ESB toolkit, it helps to enable Dynamic Routing, Transformation and Exceptions handling and considered to be a platform to realize a service-oriented architecture and by solving the problems of point-to-point service connectivity with the help of a common mediation layer (the "bus").

2 :: Tell us what are the ESB toolkit Core components?

☛ > Itinerary Services
☛ > Resolver, Adapter Provider Frameworks
☛ > Exception Management Framework

3 :: Please explain what is Routing Slip pattern? How ESB toolkit supports it?

Routing Slip pattern is widely used message routing pattern and used when a message is routed through a series of components in a pre-defined order (may be unknown during design time). ESB provides this pattern via Itinerary-based processing. A business rule can be used to select an Itinerary for a message dynamically

4 :: Tell us why there is no Itinerary status option when choosing XML Itinerary Exporter?

Because you have chosen to export your Itinerary in XML for moving it to a different environment. Once you are importing it to the targeted environment, you have an option for "Publish" / "Deploy".

5 :: Tell me can we On-Ramp / Off-Ramp message with message box?

Yes (with some trick), a message created within BizTalk Orchestration can promote properties with ESB context and published to MessageBox.

8 :: Tell us what is resolver, and can you list out the ESB toolkit provides?

A component which feeds runtime configuration values to the Adapter provider the so that it can dynamically configure the Dynamic Adapter at run-time. It is a .NET component having a collection of entries which tells what values to use for various BizTalk components.
Example: STATIC, UDDI, XPATH, BRE, BRI, ITINERARY, ITINERARY-STATIC, LDAP

9 :: Explain how to move itineraries from one environment to another (e.g. QA to Production)?

An EsbImportUtil.exe utility tool is a good option used to publish or deploy the itinerary XML into the ESBItineraryDB database.

10 :: Please explain what are the common patterns implemented in Itineraries?

☛ Message Routing
-> Message Router : determines the recipient of the message based on a set of conditions
-> Content-Based Router : determines the recipient of a message based on message content
-> Routing-Slip : a message must be routed through a series of components in a pre-defined order, which may not be known at the design time.
-> Recipient List: a message is routed to one or more recipients (static / dynamic)
-> Splitter : Breaking one message to multiple chunks
☛ Message Transformation
-> Translator : Solves the problem of translating incompatible data formats between two systems
-> Normalizer : Solves the problem when messages received from different sources are semantically equivalent but format is different
-> Content Enricher : Solves the problem by furnishing additional data to the received message required by target system
☛ Service Mediation
-> VETO / VETRO : Solves the problem using esb pipelines for Validate, Enrich, Transform, Route, Operate
-> Request-Response: Solves the problem of two-way communication
☛ Service Management
-> Repair and Resubmit: So
