Call orchestrations within scope

Hi guys,

I Posted a thread regarding steep memory requirements yesterday, but I’m afraid my description of the problem was too ambiguous.

Instead I would like to ask a more precise question…

I’m using an orchestration to Parse/Switch messages onto several underlying orchestrations… In essence, almost like a plain decide shape.

The “decider” calls a number of sub orchestrations inside a synchronized scope. The “decider” is allocated to one host and the sub orchestrations to another.

When calling an orchestration inside a synchronized scope… Does BizTalk “run” the called orchestration on the host calling the orchestration, or the host configured for the sub orchestration?

My concern is that the host running the “decider” uses a lot of memory, while the host running the sub orchestrations uses none, eventhough the “work” is done in the sub orchestrations…

thanks, Ole-Petter
