In this week's MacWeek magazine, I read an article that TOPS has problems on
high-speed networks, such as Ethernet. Apparently, it has some syncronization
and timing problems on such networks. This problem arises mailing when sharing
large files across the network, say from a shared database application (in
their example, they used Omnis-3 or something like that). The databases can
become corrupted under certain circumstances.
Does anyone know what causes this? Is this also possible when using Ethernet
and smaller files? Just curious. I don't want to recommend something that
doesn't work (although "they are working on the problem").

Not only does it have these problems, but certain databases which claim to work with TOPS (i.e., 4D) have known problems with it which can cause data or layout corruption, while the smart ones (FoxBase) refuse to use it at all. It's bad news. Fortunately, out of the blue comes a solution to this problem- distributed peer-to-peer AppleShare. Read my next message, which describes this in detail. --- Alexis Rosen alexis@ccnysci.{uucp,bitnet} alexis@rascal.ics.utexas.edu (last resort)
