RE: BizTalk 2006 FILE adapter polling interval

The polling interval is for control the workload. Because when message was
accepted in to the server, it will occuppy a lot of memory. When set up a
batch size it limited how many messages the system have to process before
getting new messages in. And interval property decide how long system
should wait to poll the receive location again, if it get no message last
time it polls.

For your scenario, if you put batch size to 1, then, system will get read
one file at a time. But it process it very quickly. So, it will
immediately poll the location again. Because the last it poll the location,
there is message, so the system will not wait for the polling interval. It
will poll again, and find one more file. So it will process it, and polling
again. Because it is so fast, It looks like to you that it has processed
all the files very quickly, without considering batch size or polling
interval.

To see batch size working, you can stop send port which uses this receive
location. And then try. You should see that only one file is read, and
pending for process. If system poll all the file in under this condition,
report a bug to me:)

To see polling interval, please put a file into receive location, let it to
be read and processed. Wait a while(time < your polling interval),then,
you put another file again. You will see system will not immediately read
it, and it will wait until pooling interval and read it.

For Biztalk server 2006, there is a new property on the FILE adapter
receive
location called "polling interval" and "batch size" that can be set from
the
UI. When I set the batch size to 1 and polling interval to 120000
milliseconds, it seems not not behaive as expected. If I place 5 files
on
the receive location it will pickup and process them all regardless of
the
batch size or polling settings.

Any ideas why this is happening?
