I have a requirement to develop a prototype that will use a SQL-based, relational DBMS in a client/server architecture. The database will be concurrently accessed by multiple users, so the DBMS must support record locking. I am aware of several alternatives using a UNIX server/DOS client approach, but I am not sure what is available using a Netware 386 server and DOS clients. I'd appreciate any ideas or suggestions.

You can setup a OS/2 database server with Oracle or you can use Informix's NLM on the server itself. The NLM's performance is unknown, because it is too new. Reliability on any NLM products should be look at with more care, because it runs in ring-0. That means the f/s can be corrupted by faulty NLM code. Of course, if the NLM is perfect then everything would be very nice. Especially when this type of setup can reduce appl-appl protocol traffic on the link and save $ on the hw. Paul
