Our business uses an enterprise supply chain management app that runs
on D3/AIX. The app has worked well for years, but the AIX server is
aging and is being considered for replacement. The IBM VAR is quoting
a replacement AIX server that is thousands more than a similar
size/speed Win server. It also seems that there is more development
and tools available for D3(NT) than D3/AIX, that D3/AIX just isn't
getting the attention from Raining Data (among others). I'm
considering jumping to the Dark Side (Win), buying a D3(NT) server,
converting to D3(NT), etc. Your thoughts - good, bad, and assuming .
.. no one is indifferent on this subject. Thanks.

Size and speed makes no difference, if you're not comparing the same
processor type and setup. What are the AIX box specs, versus the NT box?
What user base do you have?

All of my customers are running on D3/Linux or D3/AIX. I have never
personally taken on a D3/NT system. Based on all of my positive experience
and what I have read and heard about the alternative, I'm sticking with the
Force.

You have answered your own question - the app has worked well for
YEARS. Why break things? Does the app use AIX facilities for
"anything"? Perhaps the "more development" you are seeing on D3/NT is
because there are more "issues" (see recent thread about space being
lost from D3/VME on NT)

Plus, don't forget that you will be up for a platform change for the
database (switching from D3/AIX to D3/NT --> chances are that will more
than take care of the hardware cost differential!

If you HAVE to move off AIX, I'd suggest D3/Linux may be a better "safe
harbour" alternative, and on the "tools" side of things, you should
find that the tools will work just as well with D3/*nix

Hi.

Be advised that D3/NT is not D3 ported over to Windows, it is a fairly
different beast. You should be clear of your reasons to migrate and
undertake thorough application testing before you commit.

In 1999 the fortune of my company rested on a 32 user D3/NT box running
my unique local government application. With no competing product it
seemed that success was in the bag. However faced with memory leaks,
stalled telnet sessions and daily reboots the customer decided to stop
using it and I lost my business. Later when I started work with Disys I
encountered customers running D3/Linux boxes that had not been switched
off in five years. This surely speaks volumes.

Since then it is fair to say that the waters have muddied somewhat and
now the issue is not so clear cut. Windows XP is much more stable than
Windows NT and Red Hat 9 Linux has some issues of it's own.

If my business (or my job) depended on it then I would choose a
commercially supported Unix/Linux type operating system to host a
database. For developing software on my laptop I used to use D3/NT but
since my license expired now use UniVision on Windows XP.

Hope this helps.

I've never used AIX so I can't make a meaningful comment but I have use D3
on Win boxes without Windows problems. I suspect - but again we need a
comment from someone who actually knows - there may be issues with the AIX
update. I do know that one issue that you will face if you go the Windows
route is the FSI - about which you can find many posts if you Google. It's
hard to rank things without numbers.

Isn't UniVision like Universe, i.e., more of a Prime Information roots

No - UniVision comes from an Mentor (mvBASE) background

Hi Art.

UniVision can be run in a Prime Information mode or D3 compatible mode.
I have personal experience in porting a fairly complicated application
over from D3 to UniVision. Let me assure everyone that the D3
compatibility is excellent.

Yes, I am a big fan of UniVision but for the record I currently work for
EDP Plc.

I'm quite familiar with Universe and it's compatibility flags for Prime,
D3, etc. When I think Mentor, I think of the Adds Mentor, which is more of
a Pick (OA?) branch.
