The user interface for the financial applications was mainly terminal-based (or Reflection emulating terminals) via COBOL programs. Now, on the Alpha .... it is doing nothing more than ORACLE financials. No X-windows. No nothing else. Some client/server access, but mostly telnet client from a VT terminal emulator. Sure, the comparison smacks a little of 'apples and oranges', but let us not loose sight of the business case--you take the functions off MPE/Image and put them on UNIX/ORACLE and it costs you .... a lot. And let us also not forget that on the HP we only used less than one-quarter of the CPU .... so the Alpha CPU is arguably TWELVE TIMES what we were using before. The memory is FOUR TIMES the HP's--and it is doing nothing but serving the financial apps, whereas on the HP the paltry 256MB served (and continues to serve) over 200 users (typically 190 sessions and 16 jobs).
