Hi all, This is a mail message I've sent to some people who have in the past commented on SUPRA from Cincom. If anyone else can reply/help it would be much appreciated. I've posted it in the RDB,RDB_VMS_COMPETITION,OLTP_INFORMATION and VMS_OLTPSERVICES. I'm currently part of a team working on selling ACMS/Rdb into a large account here in Belfast. Up until recently it looked extremely good for these products with DBMS for any MRP work that was in the pipeline. Suddenly their evaluation of MRP systems has raised CINCOM to the top of the preferred suppliers in this area and they being good marketing people have offered Supra as the tool for all the other work. They even made a presentation to the customer in which they put Oracle,Ingres and Rdb in the same league an said that Supra was much superior. I've noticed your name with comments in notesfiles on SUPRA. I need concrete facts on some issues a.s.a.p. as the customer will make decisions in the next few days. The points I mention below are from notes you may have entered in the past in notesfiles. If it's you comment or if you can add meat to anyone else's comments it would be much appreciated. -------------- Some Previous Notesfile Comments ------------------------ 1. The products also have major performance problems, and are riddled with inconsistencies and a few bugs. Q? Need Examples Please? 2. If the customer is at all interested in workstations, it is doubtful that Cincom will support DECwindows even in the medium to long range. Q? Cincom say next year? 3. It is doubtful that Cincom will add support for parallel processing to ULTRA. Q? symmetric processing?? 4. Converting Ultra and maintaining compatibility with existing customers would be extremely time consuming and expensive. I would encourage anyone to look deep under the covers at a 'Supra' release for VMS. The best that they will be able to do is to maintain application level transparency between IBM and VAX via Mantis. Q? Any more info availabel? 5. Also he was of the opinion that Supra is no more than Ultra + LUVs (Logical User Views) + Spectra (query language). Can anyone verify this? ------------------------ End of Comments ----------------------------- Regards and thanks for any help in advance Kevin

<Hope this is not too late> 1. Ultra Bugs - : Suggest you try out different queries under SPECTRA with SORT orders and Totals, Counts etc. Due to the internal design, this area is riddled with problems. : Is supposed to support RMS as a User View (LUV). If you try RMS Indexed files with alternate keys, there are lots of potential problems - like a sweep of the entire file instead of using the Keys. 2. MANTIS - : For most internal numerical variables, it uses Double Precision Floating Point. (D_FLOAT I believe) This leads to a number of inconsistencies when printing (CONVERSEing a screen) and using it internally in a MANTIS program. 3. SUPRA/ULTRA - If IBM coexistence is an issue, they do not have a convenient supported way of migrating the metadata from IBM to VAX or vice versa (last I knew - about 7 months back). Even migrating a database is likely to be a messy affair. 4. General One of the biggest drawbacks of these products is that they are not integrated well. Every product has its own look and feel. From you go from one product to another, the entire keyboard layout and keyboard conventions change. For instance MANTIS keyboard usage and ULTRA keypad usage are so different it is too obvious they had been developed by two different groups who did not talk to each other.
