Well, that essentially means that I have to deploy one more server
with MTS on it....isn't there anyway that I can do this thing on the
Linux server? If I have to deploy one more machine...I would like that
to be a Linux one ;-))

We are planning to shift our inhouse apps to Linux & Java (GUI using
SWING), so I would like to byepass MS, if thats at all possible
somehow. I understand, I would be able to pool my connections
serverside using Java, but presently I am stuck with ODBC.

In any case, if somebody can guide me how to calculate the connection
load & query load, I shall be very thankful.

With best regards.
Sanjay.

PS: I agree that the XML idea is a terrific one and I shall definitely
wait till someone develops it....just wish I had the capability to do
it myself....anyways....someday ;-))
