Re: Do we have threading concept in BizTalk MessageBox

BizTalk will process multiple orchestrations concurrently.  I believe it uses multiple threads and can take advantage of multi-proc servers.  However, each orchestration has it’s own data structures, so you don’t need to worry about race conditions or locking objects.  The best advice I can give is to make your orchestrations as granular as possible so you can take advantage of multi-proc and multi-server environments.  If you write one big orchestration, it will probably be stuck on one proc in one thread, but if you break it into a bunch of smaller ones they can be distributed.
