I have orchestration like on screenshot below. And I want to have additional logic executed when service connected to wsp is failing or unavailable (timeout,service crash, server unavailable, etc).
It looks like I will not be able to catch this in orchestration in Scope_1.
How can I add logic to orchestration if service crashed ?
I think you want the pattern described in this article or some variation:
BizTalk Server: Suspend and Resume an Orchestration on Two Way Port Error
This pattern captures the Port error, and puts the Orchestration in a Suspended/Resumable state.
You should still properly configure the Port Retries.
