I had several customers on D3/AIX and D3/SCO (a unix product no longer

discontinued we installed D3/NT systems at these sites and almost
immediately started experiencing problems with the system.

During this time our largest customers stayed on D3/AIX and had no
problems at all.

Over the years RD has worked on stablizing the product and resolving
the issues that our customers had. Although the one of their rescent
releases (7.4.5) had major stability issues. They were able to resolve
these on 7.4.6 but it took some time.

All in all, I believe that the D3/Linux and D3/AIX products are a more
stable solution than the D3/NT route. Most any tool that you can use
on D3/NT will also work on AIX. Also, keep in mind that if you are
thinking of writing Windows applications that access the database this
can still be done via ODBC to the AIX database with no problems.

Hope this helps.

Hi
I have found some of these answers quite fascinating.
In my experience the greatest thing we ever did was go to D3NT. Properly
setup it ran with no problems like a greased rocket. The memory leakage was
a very minor issue on a 35 user box requiring a 2 minute restore every
couple of years.
On the other hand the biggest disaster we ever had was OA on an Edge Unix
box closely followed by D3 on a SCO box. Sco was totally unreliable and
totally unfixable - yes we called in the experts ranging from a Pick/SCO
specialist VAR at great expense to the local Carpetland oops sorry
Computerland gurus. The best thing we ever did was dump SCO permanently and
forever.
The site that suffered the most from this has happily moved through NT,
Windows 2000 and now Windows 2003. On the way we have gone seamlessly to
Citrix with offices statewide running something like 17 or 20 printers and
downloading from unattended remote sites.
D3 NT rocks.
Regards
Peter McMurray

We've (our customers included) never had any NT problems, either, but
that's NT for UV and, now, OpenQM. Most NT sites seem to like a
re-boot every now and then.... We do ours monthly... Takes all of 2 or
3 minutes...

The NT thing has been a constant part of my life since the mid 90's
and I've never felt the urge to go away from it, although now we're
talking mostly XP/Pro, W2k and W2003, but there's still a few NT's out
there.... they keep ducking below the desk every time I walk in....

Have you looked at the new IBM P5 185 box
http://www-03.ibm.com/systems/p/hardware/entry/185/

We will have one in a few weeks and will be loading OpenQM on Debian on
it but D3 on Red Hat or SuSE should work great as well and if you
compare feature for feature and spec for spec, the IBM box is cheaper
than a windoze box. Are you making sure also that you configure a
tapedrive of sorts into your new system? There was again another post
recently, on slashdot I believe, about only relying on tape for
archival purposes.

I don't believe it's correct that there are more tools available for
D3NT than D3/*nix. What you're probably seeing is that there are more
GUI and connectivity tools available for Windows (.NET, etc) but these
all connect to D3 over any OS. Be sure you clearly separate client,
middle-tier, and server when you're thinking about topology.

About performance: Many years ago, RISC was considered superior
technology but I have no idea if that's true anymore with
hyperthreading, dual core, and other modern "PC" CPU optimizations.
IBM tends to get more horsepower for AIX boxes by adding more CPUs.
It would be interesting to see benchmark comparisons to get some real
numbers in MIPS, but the problem is that PC (Intel/AMD) benchmarks
won't run over AIX and vice versa.

As mentioned by others, D3NT is definitely not the same as your D3AIX
and I would recommend migrating to D3Linux if you just want to get
away from big iron and OS costs. Lack of noise about AIX isn't
necessarily a bad thing. You probably don't hear a lot about D3AIX
for two main reasons. First, AIX is rock stable and always has been
the most stable platform for D3. It doesn't change radically like
Linux and doesn't require vendors like RD to endure a perpetual
development cycle to keep up with changes. Second, AIX sites are much
less vocal than Linux sites. It seems companies that pay for their
software are much more apt to quietly address their needs via business
channels than those who clammor in public forums about how everything
should be free. The exception to this is with some AIX (DG, HP) sites
that have migrated to Linux, where the quieter business mentality
still prevails. Larger Linux sites generally don't do a lot of boat
rocking unless something is really wrong like disk or memory
management.

If you are looking to get more out of your OS, there are more tools
available for Linux these days than AIX, simply because of the whole
OSS movement. Again back on topology, you need to think about what
you want out of your IT/IS resources, and then decide if IBM or
third-party vendors can provide that for AIX within your time and
budget requirements. You can also consider your D3AIX box to be
nothing more than an data/application server, and host all of your
other tools in separate boxes. (Easier said than done but a good
approach.)

D3NT has had several rocky years of growth. Some people swear by it
while others swear at it. The new D3NT 7.5 (in Beta) has a lot of
major changes that may be of interest to a lot of sites. I'd
recommend waiting until this release goes production and goes through
a couple patch cycles before deciding whether you want to switch to NT
or not. I believe this release will help to define where RD is going
with this platform.
