1. Tell me what is 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.
2. Explain me what is property promotion, why is it required?
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.
3. Tell me what can be done using Scripting Functoid?
Custom code or custom scripts can be added .
4. Please explain why would a developer create a custom functoid?
Below scenarios can tempt developer to create custom functoid:
☛ When there is no out of box functoids which can be used to complete the logic.
☛ When the number of functoids used to implement the logic goes on increasing and becomes difficult to follow and manage.
5. Tell us what are the ways to integrate custom functoid into solution?
Custom functiods can be integrated into a solution using two ways (in both BizTalk.BaseFunctoid is derived):
☛ Directly by using inline code
☛ Indirectly by reference to a method in a class library deployed into the global assembly cache.
7. Tell us how many categories are functoids divided in Tool Box?
There are 9 categories available in Toolbox viz.,
☛ Advanced
☛ Conversion
☛ Cumulative
☛ Database
☛ Date and Time
☛ Logical
☛ Mathematical
☛ Scientific
☛ String
