Actually we have a database under HP UX (HP Unix)

Our development department would like to change for NT.

What do you think about it ?

Thanks bye avance.

We were faced the same choice between Sun Solaris and NT.  I put a similar
question out last year and got a response that was slightly in favor of
keeping Solaris.

My feeling:  the devil you know is better than the devil you don't know.
We kept Solaris (but we did upgrade the hardware from a Sparc 10 to an
Ultraserver 1).  Haven't had any problems.

I've used both products, and by-and-large :

the Sybase documentation for NT is not sufficient for the job (registry and
services issues)

The NT scheduler is not as robust as Unix cron.

Sybperl is not available on NT.

Sybase is forced to use ordinary files on NT versus raw partitions available
under Unix.

However,

NT is cheaper and the NT client environment is friendlier

Hope that helps......

We are a HP-UX/Sybase site principally because we understand that Sybase
develop on HP hence fixes/enhancements AND support for the HP platform come
before any other OS.

Concerning NT in particular, my personal opinion is it's great for clients,
but when it comes to Mission Critical servers, I would rather Microsoft
iron out the reliability issues before I'll commit my customer's 7X24
operation to it!

We already have an alpha of 11.5 like the other platforms.  We're
playing with it and trying to break it...  there are benefits to
being on the cutting edge and not... I think nowadays every major
platform comes out pretty much at the same time...

: Gee...that's funny...all of us Solaris people think Sybase codes first
: on Solaris and then ports to HP-UX et al....therefore, Solaris fixes and
: enhancements should be first in the EBF pipeline.  I think this was the
: case prior to System 10, but who knows now?  Pablo?  Bret?  Teresa?

Well, Bret and Pablo are the best sources to know for sure, but I too
was always under the impression that Sun was the primary (for lack of
a better word) platform.  But that was back in the *old* SunOS days. :-)

I do remember Sybase executives talking about this at one of their
presentations at an ISUG conference a couple of years back.  It was
regarding all the quality control issues that had everyone up in arms.
I remember a statement to the effect that releases would be done at
the same time for all the platforms so that everyone would be at the
same bug level :-)  and that does, indeed, seem to be the case.

Not exactly a hard core answer, but that's my 2 cents.

The waterloo people do the workplace ports of sybase to NT. They seem
to be out in front on the 11.5 release.

You can do raw devices with NT. Create a partition but don't format
it. Specify the drive name as the device. Have to use all of device,
and you can only have 4 partitions per drive, at least with 3.51.

"Sybase Server" 2nd Quarter 1997 had an article by Jim Barrett from
Compaq on ASE 11.5 for NT showing use of raw devices. ( But, Jim,

comparisons or reliability factors between NTFS and raw devices.)

I have only been working with Sybase on NT since MAY. Despite
upgrade problems from 10 to 11, uptime is incredible, to my
own surprise. I just installed a Compaq 6000 with 2 Smart-2
Arrays configured Raid 10 across six drives on each controller,
only 4 meg battery backed up cache. Phenominal perf!

The Enterprise 450 was going to be my preference for consolidation,
now, I am rreally having some second thoughts.

( Still hate NT, but, U/WIN 1.3 is helping.)

        Solaris, HPUX, AIX, Dec Unix and NT.

All of these platforms are treated as equal for release/support purposes
(although perhaps Solaris and NT are sometimes a little "more equal than the
others"! ;-)

Wasn't Solaris the LAST OS to be converted from 4.x?

Well, since it took them almost a full year to release Sybase XI on
OpenVMS for Alpha, I guess that "same bug level" referred to the
various flavors of UNIX... ;-)

:       Amazing! And I thought it couldn't be done. But then again,
:       I thought NT didn't do async I/O.

:       Have you tested it yourself?

I did install some databases on raw devices. But, I had to reconfigure
the system for Platinum support on the current release we are using.
So, I couldn't test what I was asking Jim about.

I am not sure of the advantage. The Sybase 10 installations are crashing
due to read defer errors, and we have had power outages that Power-chute
didn't catch due to serial cables getting unplugged. Always a
resilient restart! (One time, though, drive names got remapped, after
someone installed anti-virus software off a CD. E: was F: and G:
was H: -- a lot of databases flagged suspect. Some of that
Windows-Not showing through...) Everything in production is NTFS
with async I/O.
