NT v. Linux on D3

 NT v. Linux on D3

We are evaluating both Linux and NT for our D3 databases. We have a few
questions about each:

1) What is the minimum practical (for real usability) processor, speed, ram
& hard disk needed for Win NT & D3? Microsoft understates the real
requirements for a usable NT system.

2) What is the minimum practical (for real usability) processor, speed, ram
& hard disk needed for Red Hat Linux v4.0 & D3?

3) Does NT or Linux with D3 have any advantages over the other in a mixed
network of PCs (Win 95), Macs and UNIX (Solaris) boxes.

4) Are there any performance or reliability concerns when running other
services (i.e. fileshareing, print spooling, Win 95 apps) with D3 on NT or
Linux?

5) Has anyone connected a D3 database to FileMaker Pro?

A 486DX4-100 would work okay. If you want a fully loaded RedHat Install,
24-32M would be good. For a bare RedHat 4.0 install, 16M and a 486DX4-100
would be useable; but you may need to tune some of the parameters in
your D3 configuration for best preformance.

RedHat 4.0 comes with support for SMB (allows you to talk to Win95/NT boxes),
Netware, and Unix. One thing that RedHat 4.0 can do that NT cannot do is
utilize YP to simplify login administration. Also, unlike NT, do not
have a login license restriction; under RedHat 4.0, your main concern is
number of PICK users.

It may or may not be an issue, but out of the "box" RedHat 4.0 can do
NFS (Solaris). If you need to share files with Macs, you can install
Netatalk on RedHat.

With printing, RedHat out of the box can print to any printer
except for AppleShare printers. Installing Netatalk (or CAP) will
fix that.

Because of the way Unix (and Linux) works, as long as RedHat can talk
to all those platforms, D3 can automatically utilize it.

RedHat 4.0 comes with gcc (a compiler). This means you can use the
fastest form of FlashBASIC, available only on Unix/Linux versions.

Hope this helps.

Pentium Class computer - 90 or higher, 32 megabytes of RAM - 1gig
minumum.  This is a typically stocked new computer these days (with
the exception of the extra 16 megabytes of RAM).  This is minimum.
The rest depends on how many users and how active they are.  The base
system should easilly support a 10-20 user base.

Yes - in linux you will be able to mount remote windows 95 directories
and vice versa - you will also be able to do the same for your solaris
boxes.  You'll also be able to use any shared printer on windows, mac
or unix box.  In NT you will only be able to talk to other Windows 95
or NT machines.  You can purchase addon software for NT that will
allow it to use unix nfs shares but that's extra $$$.

A similarly configured linux box will consistantly run rings around
it's NT counterpart.  Linux configuration is tougher - requring a more
experience (or persistant) system administrator.

 NT v. Linux on D3

I just returned for Pick systems for a dealer intro to D3/NT.  The NT
implementation is a complete rewrite of Pick and is significantly different
from any other D3 platform.
r
#1: Pick has seperated the file system from the virtual machine
       a) File system being any access to a pick or non pick file
       b) Virtual machine being where we execute pick applications,
interface with printers, terminals, etc.  Essentially the TCL prompt.

#2: You can now distribute the virtual machine and file system across
machines.  The virtual machines get to the new files (which by the way, are
now stored in NT or Dos directories) by using super Q pointers.  This now
allows a configuration as follows:

We have a 1000 user site, we can install NT machines and on each of those
machines we install a virtual machine.  Each machine then has 200 users
assigned to it.  Each one of those users will get a TCL prompt on their
specific machine.  All code will run on that machine, printer access will
be on that machine, etc.

We then install one or more NT machines with FSI (picks new file system
server, it is sorta like a SQL server).  Each one of the virtual machine
NT's will then create super Q pointers to the FSI to get at the files.  We
can distribute the files over a number of NT file servers to decrease our
load.

The above example is for people requiring support for legacy systems.  The
virtual machines can install dumb terminals on serial ports or PC's can
connect to the virtual machines via Telnet (D3 spawns it's own telnet
server on NT). One machine can handle all the services (FSI and Virtual
machines).  You could even feasably install a seperate virtual machine on
each Windows 95 machine and install FSI on a server and have each persons
legecy app run on their own machine!

For the future, we now have VB functions that allow us to write VB apps
that connect to the FSI and extract pick data.  Pick systems has a
extensive VB library that gives us most of the command we need.  There is a
Dynamic Record object for management of our dynamic records, a Oconv and
Iconv function, list select statement, etc.  You can also create a
connection from VB to a Pick Virtual machine and call basic subroutings
that were flash compiled.  From VB you just do

pickenvironment.brcall("pick subroutine name","param1","param2","param3")  
(my syntax is probably wrong)

This will call the pick routine and it will return values.

The product is really new and has has number of bugs to still work out but
I was quite impressed.  I have personally loaded my legacy app and got it
to work and have then moved to VB and started writing small VB forms to
test access.

In closing, Pick has stated they are working on moving a lot of the D3
functionality down to the Unix implementations.  This should eventually
allow you to set up NT Virtual machines that access a Pick file sitting on
a D3/RS6000 for example.  But at this point, the D3/Nt (this product will
also work on Windows 95, Nt workstation, and Nt Server) is light years
ahead of the other D3/Unix systems in terms of features but is way behind
in maturity.

That is, unless your problem falls out of the normal distribution.  If you
have a bizarre problem with Linux, consult the newsgroups, if you have one
with NT, good luck.
