UnixWare kicks butt!
jo...@interdynamics.com
Our two heaviest-loaded mail and web servers, running UnixWare 2.03
and 2.01 respectivly have been up for 40 days (they both lost power at
the same time 40 days ago at which time they were up for 20 days
following another power outage). Not only that, but our mail server
also handles shell accounts for our customers, and is logged into up
to 1000 times per day.
I just have to say, none of our competitors that run BSDI have ever
had this type of uptime. Our BSDI-loving competitors have a good week
if they do not crash once. Our competitors that were running Linux
(there were two) are now BANKRUPT.
After posting this, I'm quite sure both my UnixWare servers will dump
core for one reason or another, but I just had to express how happy I
am with UnixWare.

Its a good thing your'e running 2.0x of UnixWare. I upgraded from 2.03 to
2.1, then 2.1.1, then back to 2.1. I've had nothing but trouble since the
upgrade. Based on some of the answers here, SCO appears to be aware of the
problems for quite some time but fixes don't seem to happen.

Well, I have a cron job boot this old UW 1.1.2 machine weekly, but have not
had trouble after power outages (which are happily quite rare here), thanks
to the Veritas Journaling File System.

Are you saying I should be happy if my system only crashes once a month?!!!
I'm moving a transaction processing system from an old Sanyo Icon Unix/Pick
system to an Intel SMP UnixWare platform. If that is the best I can hope
for I better start working on my resume. I hope someone can tell me I'm not
about to be fired!

I can't speak for the SCO versions of UnixWare, but the Novell 2.01-2.03
releases run here without problems for months on end. One of them is the
mail server for 2000 college students, and it resides in an unmonitored
wiring closet. We also have two UW 1.1 systems running as NFS file
servers for various classroom labs, and a quick "who -r" reveals that
they were last rebooted last December (the day after the Christmas
holiday, to be exact). I think of these things as appliances, and they
require zero attention unless something breaks.
I have to give the most trouble-free PC UNIX award to Interactive (ISC)
V3.01. We have a 486 system that serves as an NFS file server and
terminal server to an AS/400 that ran from November 20, 1995 through
March 6, 1997 without being rebooted. It cracked a power supply,
otherwise it would still be running without interruption to this day.
UPS's are a great thing.....

Just think how long you could have gone if the box was on an UPS!
(Or was this an extended outage?) I remember one outage in my office lasting
some 15-20 minutes. I was in the middle of loading OS/2 Warp on my desktop
when the lights went out. All of the servers I'm most responsible for kept
running in a near-dark computer room (the Sequents were not protected). I
kept feeding disk by the light of the monitor, since I neglected to protect
my desk lamp!

Here I've got UnixWare 1.1.3 on one user's NCR 3333, and typically it
goes down only if I'm mucking around with the LanMan/X installation or the
building power goes out.

I am running 2.03 on a single processor with much success. I had
nothing but trouble with SMP under heavy load. It reached a point where
I had to reboot every nite. Once I removed the MP package (pkgrm osmp)
last August, It hasn't crashed once (& yes, I tried everything else first,
like replacing all hardware with different vendors' products & ptfs &
2.01, 2.02, 2.03 & taking a processor off line (so it was effectively
running 1 processor. (I did have to take it down to add disk space once,
16 Gigs now).

Couldn't resist the a followup to this, even though it's not technically
about Unixware. However, I do run UnixWare 2.03 at home and do find it
a stable platform for use as my home server (web server, msql database,
file server for several win95 pc's, etc) but here's the 'uptime' from
the server I do the most work on at the office (NCR, Columbia, SC):
folsom-buzz-130(3C): uptime
1:32pm up 197 days, 4:22, 116 users
It's about 40 days from a mandatory reboot (when lbolt in the kernel
rolls over).
The machine: NCR 3550, 8 processors, 512M of memory, 38G of storage.
The OS: MP-RAS Release 3.01.01, NCR's Unix SVR4 variant(deviant?).
