Each of the supported platform hardware vendors has a 'competency' center located within JDE to do sizing. Many hardware companies do sizing and are OK at it. The problem is Hardware Companies want to push boxes, and Hardware vendors/resellers don't know JDE and take the Hardware vendors word for what a client needs. 70-90% of the sizings I've reviewed are just dead wrong. Current Platforms that support Oracle DB are Intel, Sun, HPUX, and AIX on an RS6000. There are a lot of factors that determine sizing and a lot of questions that go into Architecture design for Xe. I am not familiar with Digital and Oracle is not a super popular platform for JDE due to the cost of ownership and maintence. I've seen a trend to move away from the Unix/Oracle platform because finding resources with the proper skills to do it and do it right within the JDE Market is very hard. I have worked on Many Intel/Oracle and Sun/Oracle shops and there is a lot that goes into it.
# of users, types of transactions, volume of transactions, # of locations, Fat Clients vs. Thin, application servers, bandwidth, modules being installed, etc.
If you are deadset on Oracle, I will lay out a table so you at least know the disk configuation you should consider on the Enterprise Server.
Area SCSI Channel # Of Disks Redundancy Files
1 SCSI Channel - 1 2 Mirrored Oracle executable and user area, a control file, System tables and Redo logs
2 SCSI Channel - 2 3 (Minimum) RAID 5 Data files, a control file and Redo logs
3 SCSI Channel – 3 2 Mirrored Index files, a control file and Redo Logs
4 SCSI Channel - 4 2 Mirrored Rollback Segments
5 SCSI Channel - 4 1 (Minimum) None – can be Mirrored Archive log files
6 SCSI Channel - 4 1 (Minimum) None – can be Mirrored Backup Staging and Export file
Area 1 Oracle executable and user area, a control file, System tables and Redo logs
Area 2: Data files, a control file and Redo logs
Area 3: Index files, a control file and Redo Logs
Area 4 Rollback Segments
Area 5 Archive log files
Area 6 Backup Staging and Export file
I hope this helps. I will be more than happy to talk to you in person, I ran the CNC practice for a JDE BP for a few years and worked extensively in sizing by reviewing the all the factors I mentioned before.
Have a great day
