Gigabyte Network Problem |

Peter Hodgson | Hi
I have had a DBISAM Server running on a Win 2003 server box for 5 years with no problems. I supply and maintain all the infrastructure on the site and the whole site is now running a Gigabyte LAN apart form the Win 2003 server. When I put a Gigabyte LAN Card into the server and hook it up my App immediately has problems, it crashes and burns straight away. It works perfectly on the 10/100. I have tried different makes of card. This occurrs on both Win 7 and XP Clients, I cant run my app over the Gigabyte LAN everything else works perfectly. I also have on site a FreeNAS server running solely on the Gigabyte LAN with the client often having 100+ documents open at any one time, so I cant see any problems with the LAN or cabling. The cabling from the Win2003 server into the backplane is Gigabyte certified. This is my 5th year of living off just this one client. The App is business critical for the client and as I originally only sold the client a license (I own the copyright) I am the sole supplier/contractor. DBISAM c/s is the best thing I ever bought and I expect it to keep the bread on the table until I retire in 4 years time. Thanks to you Tim I work part-time doing something I enjoy, live in a nice house and drive a Jaguar(err... when its running, but thats another story....). Any advice appreciated. Peter |

Can you access the tables using DBSys in client server and/or file server modes with the Gigabyte card in? Roy Lambert |

Raul Team Elevate | Hi Peter,
Sorry - are you running a gigabit LAN (e.g. 1000BASE-T) or a LAN card from Gigabyte Technology (manufacturer)? Is your gigabit network switch managed or non-managed ? Couple of things i would suggest trying (you may tried these already): 1. Is the server connection running in full gigabit full duplex-mode when you check its status ? If it's set to auto-configure have you tried setting both speed and duplex manually? 2. You mentioned it works with 10/100 - did you try that with same gigabit card forced to 100 or with another card. If another then how about forcing the card to 100/full-duplex on server? 3. What happens if you ping the server from client (e.g. ping -t) - any dropped packets or excessive timeouts) 4. Are jumbo frames enabled on server? if so then try setting it back to approx 1500 byte packet size 5. Not sure which card you have but some of them come with diagnostic utilities that may help (Broadcom for example has one of their Control Suite that can test card and even cable apparently). Raul |

Roy Lambert Hi Roy Its a very busy office and I could only take down the system for an hour which was only long enough to find out that it didnt work. Hi Raul Thanks for your suggestions. I think the only thing I can do is simulate the same conditions and see what happens. The switches are 2x20 port 10/100/1000 unmanaged - when I say gigabyte I am referring to the speed not the make. I am running the NAS on gigabyte(10/100/1000) and a backup server with most of the clients accessing the NAS with gigabyte(10/100/1000) without any problem. I am going to set up a Gigabyte LAN for testing here in the office so I can see whats happening in a non-critical environment. I was just wondering if anyone had any ideas or had seen the problem before. Thanks Peter |

They are similair in that department. Rita |

As far as my DBISAM app is concerned, it goes as far as the splash screen and crashes and burns. It just pops a windoze box that says 'your app has encountered a problem etc....'. My app is 100% reliable over the 10/100, I have never had a single incident reported in the last 5 years (apart from some figures that havent added up....). Thanks Peter |

Are you handling all the exceptions? If not then putting in a default exception handler might shed some light on what is happening. For quick test easiest IMHO is to put a handler on the Application.OnException and just show a message window. More info on that : http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/delphivclwin32/Forms_TApplication_OnException.html and another nice example here : http://www.chami.com/tips/delphi/011497D.html Raul |

I have been running a FreeNAS box on the site for 2 years but having problems with Windows 7. Problem is apparently Samba related and I cant find a solution to the problem. I am going to replace it with an OpenSuse box but there are logistics around this in a busy office, including getting 200,000 documents off the old box in the night time. And to add to that two new Windoze 7 machines I put on-site last week have developed hardware issues. They are identical so I guess all the components are from the same batch - happy days..... All reasonable exceptions are handled but not things like form.hide which are not usually issues. I am upgrading the office LAN to Gigabit next week when I have a moment and will test here in the office. Regards Peter |
