We have a CASE 5.0 environment: Sun Solaris Server
                                PC's running X-emulation
                                Dec X-terminals
                                Sun Workstations (Solaris & SunOS)

Because of the mix of equipment on the desktop, running the ORACLE client processes on the database server and using the desktop machines as X-servers allows us to provide virtually all of our users with access.

However, we have spent some considerable time trying to make each configuration work : (i.e. configuring Sun Workstations, configuring Dec X-terms,configuring PC X-emulators, ), and it pushes the database server quite hard. CASE*Designer displays fastest and most reliably on the Sun workstations, but can work quite well on a fast PC with a X emulator.

Possibly the most important factor to consider is the direction ORACLE are going with CASE 5.1/CDE Tools/CASE*Designer 2 (currently under development)

• i.e. PC / MS-Windows, and choose good PC's.

Good luck, Kevin.
