We see a strange phenomen on one of our remote plant networks.
The W2000 clients (Chinese version), running OpenRoad4.1 applications, are defined on the same subnet as the Ingres 2.0 DBMS on HP-UX 11.
An external DNS is used.
Each time the internet line doesn't work, then performance of the client/server applications is dropping significantly.
This is very strange because the clients use the ip-address of the DBMS server in their middleware component (IngresNet) for establishing a DBMS connection, so there is no need for a DNS lookup, I guess.
What can cause this ?
Thanks in advance,
Franky

Re: client server performance drop when internet goes down
You should have an internal DNS server for all internal IP's that also forwards requests to the external DNS for internet names and IP's.

Re: client server performance drop when internet goes down
Thanks for helping to solve this problem.
I am only aware of some basic DNS & networking stuff.
John,
The w2000 clients connect to the HP-UX DBMS server by using the servers ip-address.
Why should the clients be waiting for a DNS lookup of their own IP's in this case ?
Jon,
Similar question for your answer. Why should the DBMS bother to qualify the clients address if the clients connects with the ip-address ?
Regards,
Franky

Solutionit has nothing to do with the application using an IP to connect to
it has everything to do with the terminal itself connecting to TCP/IP services on the server

Re: client server performance drop when internet goes down
Now, I realise that the problem is not the client being able to use the ip-address of the server to connect to it, but the fact that the simple addressing itself of the TCP/IP services of the server causes a DNS lookup on the server, I guess.
As you, and the other contributors suggest, a local DNS service will solve the problem, and that's what we are up to now.
Further I am anxious to know more about this process of clients addressing the TCP/IP services on the server. What is exactly happening causing a DNS lookup ? Is it possible to shortly point this out a bit more ?
Anyway, thanks for sharing your expertise.
Regards,
Franky Leeuwerck

Re: client server performance drop when internet goes down
Just because Windows has a long history of calling machines by names (the old Netbeui stuff), most of it's configuration goes thru names anyway, whereas it's your server of your client's name being to be resolved...

Re: client server performance drop when internet goes down
As mentioned earlier : the client uses an ip-address for connecting to the server.
If I understand what you explain then it is the server's name that is being resolved by the client. This way of doing things is typical for Windows TCP/IP networking, correct ?
Thanks for your input.

Franky
