Help, I need somebody, help not etc. etc. etc.

Hello fellow Informix users, I need some advise. We are using Informix V4 on an IBM RS6000 model 320h with 64mb of REAL ram. We are currently looking into buying a MRP (Materials Requirement Planning) system and the best one we've seen at the moment has been written using the PROGRESS database. Does anybody have any experience of linking this DBMS with Informix, is it possible, and if so how easy is it. (I'd need a on-line connection I wouldn't want to do it with CSV files or anything silly like that). Also as part of this new system purchase we're going to possibly upgrade our RS6000 to a later model with more RAM. Would someone give me some advice on what model to buy (I know this is the Informix group but I'd hope somebody out there would be using a RS, if not then I apolgise for wasting your time) System Usage: We will have around 32 concurrent users, using applications developed mainly in Informix, and possibly Progress (see above), they all use dumb WYSE terminals (that sounds a bit silly!). We have a small (5 user) TCP/IP network running off the RS, we are using the Informix Standard Engine, 4GL, R4GL and SQL. The options I have currently looked at include:- 1. Buy a IBM RS6000-360h with 128mb of RAM. 2. Buy a model C10 with 128mb of RAM. 3. Keep the current RS6000-320h and upgrade it to 128mb of RAM. Would someone please advise me on the best course of action. Wwould we get greater speed performance by using Informix ON-LINE instead of standard engine? I look forward to receiving some responses, I'm sorry for the length of this post, it's us British people we're a bit dumb and talk to much! Thanks.... -- Paul Eccleston, England
