believe we couldn't get A97 to replicate over the Internet at all so we
tried converting the app to A2K2 and that would only work over VPN. We had
a developer talk to M$ on the phone or via e-mail for a week or two and the VPN
was the only way it would work (M$ could not get replication to work over the
Internet either, FYI). If you had a non-VPN replication working do you
have any "secrets" to share?</FONT></SPAN></DIV>

<DIV><SPAN class=650361016-31032003><FONT face=Arial color=#0000ff size=2>No, the Access97 replication is done straight through the
phone lines. The government has been using it's own internal network,
first through fast dedicated phone lines and finally an 'Ubiquity' fiber-optic connection that now covers most of the province. I have ran
Access97 through the net and noticed no major problems but it was only a test
and not under full load.</FONT></SPAN></DIV>

<DIV><SPAN class=650361016-31032003><FONT face=Arial color=#0000ff size=2>It
should be stable in the current versions of Access, even running across the

would be any more or less stable than a standard internet

<DIV><SPAN class=460394011-29032003><FONT face=Arial color=#0000ff
size=2>I have been running a Access replication application for five
years. There are basically three government offices with about forty total
individuals. The program has both an automatic and manual replication process programmed in. I have one BE db with one table
that is centeral to the process. This is the file that supplies all
the invoice numbers. It is linked to each site by its URL address. As soon
as a ne record is created, the program goes looking for the next number.
If the lines are glogged, that can take about 30
seconds.</FONT></SPAN></DIV>

sometimes the timing is off. The issue only comes up once every couple months or so. The cost to permentantly resolve the
problem, with a nice SQL BE, is prohibitive so the clients have settled on
this type of solution.</FONT></SPAN></DIV>

call to file claims, they fill out paperwork and submit it. Not
that your situation won't occur, of course it will. I can
certainly ask how often it occurs but having spent 8 months on site I
didn't get that it happened "several times a day". People call to
"check" on their claim that is already in the system - having been entered from a claim form. The folks handling the phones do take
info over the phone, but mostly it is "fill out this form and mail it
in", or "get your doctor to fill out this form and mail it in" or "get
your employer to fill out this form and send it in". No paperwork,
no claim! So people "calling back with info" simply isn't a common
occurrence since they don't ask for verbal information other than current address and the likes.</FONT></SPAN></DIV>

the occasional "out of sync" info in order to get a doubling of
effective speed.</FONT></SPAN></DIV>

<P><FONT face=Arial color=#0000ff size=2>I'm not saying your solution
doesn't work. I pointed out a situation that will arise and that
they need to have some procedure in place to handle it. Whether
that procedure is within your solution or something they will have to
handle manually is for them to decide.</FONT></P>
<P><FONT face=Arial color=#0000ff size=2>As to how often such calls
occur, all I can say is when I worked for my Dad in his insurance agency it happened several times a day that somebody would call to
file a claim but didn't have all the information the agent needed so
they would have to call back later with the additional
information. I doubt that human nature has changed much in the
intervening years.</FONT></P>

<P><FONT face=Arial size=2>They need an answer, and can't afford SQL
Server. This is an answer. To not look at the realistic
options because of the 1 in 1000 (or whatever) occurrence is not realistic.</FONT></P>
<P><FONT face=Arial size=2>I am certainly open to other options.
However they just spent 8 months moving an old creaky flat file to a
relational MDB FE/BE. They don't have a budget for a $10,000
solution at the moment. What solution can they get for
$500? Moving to SQl Server will be $5k or more. They don't
have that, they have said so. I have done all of the typical
"make sure the fields are indexed" things.</FONT></P>
<P><FONT face=Arial size=2>So rather than saying "this solution
doesn't work", why don't you suggest a solution that does?</FONT> </P>
