Abdulaziz Jasser | 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). Regards |

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.

Jason Lee | 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 ~Jason Lee Oliver Bock wrote: > Abdulaziz Jasser wrote: > >> I am trying to connect my application to the server using a DSL with >> no sucsess.

Abdulaziz Jasser | 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? |

I guess it depends on what type of application you are using. Which version of DBISAM are you using? -- Stuart Kelly mode software |

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

"Adam H." | Hi Abdulaziz,
> 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? 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. |

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, -- Stuart Kelly mode software |
