Big Performance-Problems using ISDN

Hi All!

We want to use Oracle SQLNET via ISDN. We have two different configurations:

    RS6000 with AIX 4.1, Oracle 7.1 Server, 64KBit ISDN-Connection, SQLNET V1     SGI with Irix 6.2, Oracle 7.3 Server, 128KBit ISDN-Connection, SQLNET V2

Our application uses embedded SQL to access the Database. The databases are using the default configurations recommended by Oracle. As long as we work inside a LAN, the performance is great. When we start to work across the ISDN-Line with up to 25 clients, the performance is _extreme_ bad. It is not possible to work with the configurations at all. It is interesting, that neither the line capacaty nor the server load gets higher than 30%!

We want to know the following stuff:

• Who else uses a similiar configuration _without_ performance problems?
• What kind of configuration changes may increase the performance?
• Do we have a conceptual problem using this kind of network configuration?
• Is it possible, that the ISDN protocol itself slows down the transport of packages?
• Are there any other ideas to solve the problem?

Thanks in advance for your support! Received on Mon Nov 10 1997 - 00:00:00 CET
