| I am maintaining the state of my orchestration in orchestration variables.
How could a client of my orchestration (an aspx application) have access to
these variables?
I would also like to know the recommended best practices of obtaining the
state of an orchestration. For example, how can my client application obtain
state information on the fact that the orchestration has reached a certain
point in its instance lifecycle?
Thanks in Advance,
Thilina

| Take a look at using BAM. You can easily collect milestone data as well as
key data values and provide them in a rich analytical environment. You can
also use the BAM view to get the current status and then query your service.
if you want to get data out of the actual instance of the orchestration, you
can put a web service over top of a port that does a request response on
your service instance (correlated) and returns whatever state you have in
the orchestration.

| Hi Matt,
Thanks a lot for your response. Would it be please possible for you to
elaborate on obtaining the status via a web service? My requirement is to
obtain the current status of a workflow instance in an online manner. For
example, in a Human Workflow scenario, how could we know the present
participant / stage of the instance?
Could you also tell me where I could find a detailed guide on configuring a
web service to obtain this information.
Thanks a lot,
Thilina

| If you have a running web service, you can expose a request response port on
the service as a web service. This is documented in the help. When you get
a message in on that port using correlation (also documented) you can return
a message containing the state information you are looking for. For the
workflow, I believe the HWS web service provides a good deal of what you
need in terms of getting a list of active workflows and figuring out what
the last action was and by whom,etc. All the information you need on
setting up a web service should be in the docs. Just make sure you got the
doc update from MS on their web site (April was the latest I believe).
