Hi,
What kind of binaries for SCO Unix (ODT 5) can i execute on my
Linux box under iBCS2 emulation?
Compilers like Microfocus Cobol?
SQL Retreiver?
DBMS as Ingres or Imformix?
Many thanks in advance

Put simply, yes. However you will need the latest (February) release to run
OpenServer 5 ELF binaries (and a 1.3.54 or later kernel). The SCO ELF
support is very new. However most SCO programs are still COFF (since SCO
didn't have ELF before OS5) which are fine.

CAUTION ! SCO has switched to ELF binary format in ODT5. I'm not sure if
anyone has tested SCO ELF binaries under iBCS2.
Since most programs offered for SCO are still 3.2.4.x COFF versions, you
won't have too much problems, though.

I know of the following working products:
- Informix SE/4GL/RDS/SQL 4.x
- Informix Online 5.x was reported to work
- WordPerfect for SCO
- Uniplex
There are surely lots more...

The next release of iBCS (due a couple of days ago, sorry) can do SCO ELF as
well.

Hello Mike,
The latest (February) release of what ?
Of Microfocus Cobol, SQL Retreiver, Ingres, Informix, ... :-)
If you think about the latest release of your (invaluable) iBCS2, then would
you mind sharing it with the rest of the community in the near future?
Or do you still think about commercial releases of this package?
FYI: Though not officially offered (or even supported), the current public
SCO-ODT release of Simple++ (one of the leading discrete event
simulation packages) does work under iBCS2 like a charm. As it appeares
to be faster than under SCO-ODT (on the same machine), I decided to drop
SCO completely from my system. And even better news: Under Linux/iBCS2
it is about twice as fast on a Pentium-PC (90MHz,32MB RAM) than the
current SunOS-4.x release on SunSparc5 (100MHz, 32MB).
Great work, Mike & Co., carry on !
Greetings from Beck'sTown, Germany,

I'm trying. The throughput from here to tsx-11 is currently pathetic. I
could type the hex quicker :-(.

Last time I did any benchmarking, Linux+iBCS seemed to have the same system
call speed as a SCO machine of twice the speed (roughly). Of course, this is
only a very, very small percentage of most program's execution times. The
main benefit is Linux' dynamic buffer cache that tends to hit disk far less
often than SCO. The greatest loss is the need for bloaty static binaries or
foreign shared libraries. In most cases the benefits win however :-).

What about kernel drivers from SCO like drivers for a GDT3010 SCSI Cache
Controller. Will it be possible to load them as modules into the linux
kernel. I have heard that there is a defined interface between the
kernel drivers and the SCO-kernel, so it should be possible. Is any
one working on it? It would be a great advantage over SCO because
nearly every hardware has a driver for SCO.
But because I know how stable SCO is, if ibcs2 will provide a interface
for SCO kernel drivers they should be totally separated from the normal
linux kernel! (May be as a task)

Unlikely to happen. Although the interface is defined there are underlying
assumptions about how the kernel works and what its requirements are. How
easy it would be to translate these I don't know.
One of the aims of the LiS project was to be able to make use of SVR4
STREAMS modules but, to the best of my knowledge, that project has died - or
at least entered indefinite suspended animation :-).
Anyway, in general I suspect you would be better off writing a driver from
scratch.
