Users keep complaining about their DB connection from ADP projects keep
disconnecting.

Even when I develop i get disconnected, and I don't leave it unattended for
over 3 minutes

What's going on ?
can you make it automatically reconnect or something ?

Disconnected? Can you be more specific about your installation and the
error message?

Sounds like you may have a couple of issues.

1) Your WAN is not stable. Somewhere along the way you are having network
issues.
2) You may need to reveiw your application's design. Even with an ADP, it
is very important to understand the how things work in a remoted
environment. You need to make sure that ANY data that is requested from the
server includes a very narrow WHERE statement in order to limit the data
transfer to a bare minimum. You should NEVER try and open a full table
accross a WAN. The ideal is that you use stored procedures with parameters
that limit form data to a single record. I have found this works very well.
The trick here is that the built in navigation doesn't work.

HTH,
Jim

I will add to that that recently I have seen an unstable VPN connection with
a machine that has been infected by spywares. At least one of these spyware
was spoofing is TCP-IP address; which resulted by the server dropping the
VPN connection after a few minutes.

One way to verify that would be to see if Enterprise Manager is also
dropping its connection after a few minutes. If it does, than clearly ADP
is not responsible here.

Hi,

Will using linked tables help my cause?

Enterprise manager doesn't give me any errors over periods of time, but I'm
not sure if it automatically reconnects from a dropped connection.

Of course you may try with linked tables. Even if if doesn't help your
case, it can give you precious information about the cause of the error by
chance.

What kind of connection/configuration are you using?
