I am trying to connect my application to the server using a DSL with no sucsess.  Has anybody tried to run a
DBISAM application in C/S mode over a DSL line?

If you are using a router or firewall, you must have opened the port
used by your application (Port on the session component).

We've tested our application over DSL via a VPN.  It works, but is
unusably slow.  This is the fault of DBISAM, we haven't taken the time
to find out where the problems are and move such work to the server.

You do need to be aware that the high latency will make any
database-using loops running on the client very slow.  People on this
newsgroup have also reported problems with some reporting tools.

I think Oliver means ..."this *isn't* the fault of DBISAM"...

We are using DBISAM apps over DSL and it works great when the apps are
architected for lower bandwidth rather than LANs.

When I say "architected" I mean:

Use RemoteReadsize property when traversing datasets
Use server side procedures and events where possible to do tasks
Avoid lookups and master-detail relationships where possible
Use multi-threading to perform background tasks
Use higher compression levels
Turn off encryption if not needed
As with any DBISAM app, optimize indices

Julio,

I am using a DSL modem that has a built-in router and have no firewall.  How to open this port?  Could you give me some details?

We use DBISAM over VPN without problems.  I guess it depends on what
type of application you are using.

Which version of DBISAM are you using?

DBISAM 3.30 and the same application works fine on a dialup connection.

Hi Abdulaziz,

How to open this port?  Could you give me some details?

You'll need to read up on NAT, and port forwarding. The steps will be
different for each type of modem, but in short, what you need to do is Port
Forward the DBISam server port from the 'outside world' to the computer that
you're hosting the server on.

The manual should have more information on NAT and Port Forwarding, which
should help you.

Cheers

Adam.

What make and model of modem/router is it?

Also if your using Windows XP check that the DBISAM server has an
exception in the firewall for port 12005 and 12006 if you require
administrator facilities.

Kind Regards,

Hi Stuart ,

The firewall is off.
