Re: VMS versus UNIX
Thank you for bringing that whitepaper to our attention. Personally, I had not noticed that paper on TCO, although I have cited some of the other TCO papers extensively.

Re: VMS versus UNIX
There will always be people irrationally biased against VMS or biased towards Microsoft or other, but more whitepapers like this can help to convince the sane ones.

Re: VMS versus UNIX
Although I wonder WHO did the testing of running VMS 8.2 on Integrity for five years??
Was this somehow "tranlated" from earlier versions on AXP, or was it extrapolated from 5 days (the report was from januay, and 8.2 was only released mid-january).
In my view, it would have been more convincing if they had used real-world measurements...
FWIW
Proost.
Have one on me.

Re: VMS versus UNIX
I'm sure that you can find documents on the IBM or Sun site that prove that their platform is cheaper.
Take the "change costs" on page 17. Average application porting cost : 0$ for VMS. Then they should come and look to our applications ... HP estimated 100 days and it became 1000 days (env and applic).

Re: VMS versus UNIX
nevertheless, it holds some truth.
My two cents:
* I once did the techical maintenance of an application (based on an (at the time) HP product, using Oracle 6) on a smaller HP machine running HP-UX9. When upgrading to the then latest PA-RISK platform, this required the lastes OS version, the latest version of the product and a next Oracle version. It has taken me a year to prepare and test, and one week to get the whole thing running smoothly. (the transfer of data took the whole weekend, but the backlog of processing required a week to die out)
* SUN (and IBM) keep telling that conversion to their platform is cheaper. What they do not count is the cost to port the application, cost of data conversion, cost of inavailability, and the risks involved.
Any good OBJECTIVE whitepaper to be able to calculate these is welcomed.

Re: VMS versus UNIX
Its available as a pdf file at various places.
e.g
http://web.mit.edu/~simsong/www/ugh.pdf
http://catalog.com/hopkins/unix-haters/handbook.html
This manual explains exactly why unix is a really bad idea. Yes its dated but is it wrong?

Re: VMS versus UNIX
If like it seems to show linked document, VMS has more stability, more safety and major facility of control.
Why does proportion grow between the systems UNIX installed and the VMS for big projects?
Might it be a problem of formation of new managers?
Lack of information about operating systems?
Minor develop of freeware software to VMS?
Saludos.
Daniel.

Re: VMS versus UNIX
VMS : HP
All proprietary OS (MPE, AS400, MVS) are being banned ...
Also : Unix sources can be exchanged over Unix platforms without big changes. When they visit VMS some rewriting must be done to make it work/performant. Also : you need to find someone for doing (and keep doing) the job.
Also : DEC did bad marketing 15 years ago.
