2⟩ 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

3⟩ 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").

9⟩ 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

14⟩ 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

16⟩ Suppose I can see my Itinerary in the EsbItineraryDb database and set the correct resolver connection string in the pipeline but I still see the error "The itineraryESBTransformServiceItinerary was not found in the repository. ", why?

The Itinerary need to be in the Deployed status in order to use it. To verify this, you can either check nStatus column value "1? in Itinerary table or ItineraryStatus column in Visual Studio by selecting Model Exporter as Database.

You won't be able to call the itinerary in Published status.
