Hi,

Usually for each incoming message, there is a new instance of
orchestration is created.
To avoid new instance, Singleton needs to be implemented for
orchestraion.

ok, for Messaging alone solution, does any new messaging instance is
created for each incoming message,
or
only biztalk runtime takes care of messaging with out creating any new
instances ?

i mean, i'm trying to have only one instance of messaging solution and
if possible ordered delivery.


TIA

Ordered delivery is possible using a MSMQ queue.  Otherwise none of the othe
r
messaging protocols in BizTalk guarantee first in-first out delivery without
incorporating a convoy of some sort.

With strictly messaging based solutions, the concept of a singleton doesnt
exit, the runtime is responsible for delivery and distribution within the
message box but you wont be able to achieve ordered delivery unless you use
MSMQ.

BizTalk Server '06 supports ordered delivery for all sendports regardless
of adapter (and hence creates a singleton when you set this flag). If you
are using '06, simply set this flag and you will get what you are looking
for.
