CHAPTER 26. Client/Server Communications
Network adapter boards have configuration settings that allow them to use different interrupt request (IRQ) levels. The network adapter board may work only when it is using the same IRQ level as another adapter board in your computer (for example, your parallel card). Performance may suffer when the network adapter board shares an IRQ level.
The drivers for some adapter boards have parameters. The most important type of parameter to look out for is one that controls buffer size or number of buffers. For example, some versions of the NDIS driver for an SMC PLUS Ethernet adapter have these configuration parameters:
ReceiveBuffers = 12 ReceiveBufSize = 768
The default packet size for Adaptive Server Anywhere is 512 bytes. The maximum buffer size used by the adapter board should be at least 600 to allow for protocol information in the packet. The computer running the database server might need more than the default number of buffers used by a driver.
