Very Computer

Does anyone know if there are any performance issues with running
Openingres 1.2 on NT compared to Unixware?  

We have been developing a new database system using Openingres1.2/OpenRoad
using Unixware as the operating system, but are concidering taking it over
to a server running NT.  Any advice would be welcome.

This could explain why Compaq, and not Sun, could afford to buy Digital.

  1) More memory
  2) Twice as much CPU power
  3) More patience
  4) More time, so give up a hobby or two

I assume you are doing this to be on a mainstream platform.  Might I
suggest Solaris x86?  Or possibly a full blown SPARC with Solaris?

The new SPARCs are very affordable, and they live longer.  Most SPARC
systems built after 1991 are still being used today.  Most PC's built
before 1995 have been melted down.  Why would that be?

I DARE you to ask me about our Java solutions ...

If planning to move on NT, use NTFS file systems on SCSI disks. I also
suggest to use a biprocessor machine, since OpenIngres can take
advantage of this.

To be very honnest with you, I would stay on Unix.

Cheers,
Armand

In a test I saw, a RDBMS (not OI) was tested on identical hardware
(Compaq, 4 CPUs, if I recall) using UnixWare, OpenServer, NT and OS/2.
The results: (sorry, I don't remember the units)

        UnixWare        35
        OpenServer      28
        NT              25
        OS2             21

and the new UnixWare 7 is even faster, though not yet supported by OI.

Thank you,

Actually, I think NT would be almost usable.  I do indeed use telnet
servers and PC Anywhere over the Internet to easily achieve remote
access.  And I use bash from the Cygnus toolset just fine.

The most stupid thing is that if you change ANYTHING that requires
the Windows NT disk be inserted and copied from, you must re-apply
service packs.  There are scenarios that turn this process into hours
even when you use VERY FAST, fully supported hardware.  

This is what truly sucks.

Oh, and NT threads are as heavy as Solaris processes.  What can you
expect from the person who designed VMS, the world-record holder of the
"huge processes from hell" title.
