I'am running a Linux RedHat 8.0 server with zope-2.6.1.

I wish to connect to a DB on a remote server. It's a Dataperfect DB (running on MS DOS).

Is it possible ? Is there an adapter for Dataperfect ? if not, how would you do it (without migrating the DB) ?

It's possible, of course, though likely not entirely easy. It's unlikely a Zope connector exists for it, and I can't even find a Python DB-API implementation. (In fact, I can't even find an ODBC driver.) Most likely you'll have to write your own adapter if you want to use it in Zope. This may or may not be hard, depending on how your database handles connections and transactions. A very naive implementation might actually be quite simple: it's in the performance and threading and transaction issues where things get difficult. The source of the existing DAs and http://www.zope.org/Members/petrilli/WritingADA should be helpful. Also, existing remote connection software can provide understanding of what you need to do, or even be used (via the Python/C API) to do some of your work. In this case, it may be easier to use the Firestorm and your existing data, but that's massive speculation. --jcc (massively speculative)
