Dave asks:

No. Image needs to be able to directly interact with the disk storage
managers and the memory management system, plus of course the transaction
manager, in order to manage I/O to the database. None of the interception
products (NetBase, NFS client, etc.) developed for the 3000 has ever
intercepted at these levels. I can guarantee you that there's no way to do
exactly what you're asking.
Now if you have some server somewhere that can respond to higher level
requests like "dbget", "dbput", etc., then it's not too difficult to build a
simple NetBase-like set of interception routines (though without the fancy
caching and prefetching stuff probably) that simply transports the 3000
applications db-call parameters over to that system and then returns the
results, or translates the Image requests locally into something that a
foreign database understands.
But if you just want to put the physical storage for Image somewhere else,
then you're out of luck.
