	This seems to work, giving me 90% functionality.  I'm having trouble
specifying display-specific resources in xdm-config.  Here's what it looks
like:

DisplayManager.servers:         /usr/lib/X11/xdm/Xservers
DisplayManager.errorLogFile:    /var/X11/xdm/xdm-errors
DisplayManager.pidFile:         /var/X11/xdm/xdm-pid
DisplayManager*resources:       /usr/lib/X11/xdm/Xresources
DisplayManager*session:         /usr/lib/X11/xdm/Xsession
DisplayManager.remoteAuthDir:   /var/X11/xdm
DisplayManager*authorize:       false

If I add the line

DisplayManager.0.resources:       /usr/lib/X11/xdm/Xresources-0

so that I can specify different resources for the local display, it doesn't
seem to work.  I've tried variations on _0 and _0_0, etc. without any success.
Can anyone offer a hint?  BTW, we're running under 4.2a.

I had to make some kludgy kernel configuration hacks dealing with 
max processes and some of the calculations in param.h to get pathworks to
function in a large lab (more than 50 PCs). It works acceptably now, 
and the labs get beat on heavily. Before I made the hacks, it was 
unusable after a certain load threshold. 

Maybe DEC has this fixed now, or knows how to tell you to fix it. If not
you'll either need someone who knows what they are doing, or someone
(like me :-) who delights in kludgy hacks to make it work in an 
environment with lots of PCs.

Per, 

I noticed the same problem when Iran my 5000/25 on 4.3..  I found that if I
waited a few minutes, it started recognizing the mouse.  It was acting like
some mouse daemon had to get warmed up before the mouse would work.
I then upgraded from 4.3 to 4.2 because of the reboot on modem line hangup
feature added to 4.3.

I am beginning to wonder if Sun wrote 4.3 to run DEC out of business!

What Marcus says is probably true, but it's not necessarily the whole
truth.  His changes avoid some NFS read operations, which are marginally
slower than reading from a local disk, but probably not so much slower
(unless your NFS server is wimpy) that they account for the entire
problem.

If your working directory is also NFS-mounted, then the real problem
may be that NFS writes are awfully slow.  You can speed things up by
installing PrestoServe on your NFS server, or by using NFS server code
that does "write-gathering" (such as comes in ULTRIX 4.3), but the
specific problem is that the loader tends to do all sorts of
random-access writes to the final output file.  I think this is worse
when lots of libraries are involved, since many more symbol references
get resolved.

What I sometimes do is:

foo: /tmp/foo
	cp /tmp/foo foo
	rm /tmp/foo

/tmp/foo: foo.o $(LIBS)
	cc -o /tmp/foo foo.o $(LIBS)

Believe it or not, this can run twice as fast as the more direct
method (especially when lots of X libraries are used) because the
"cp" command does the NFS I/Os in nice big chunks.

I believe it spots that the two directories are really the same

The latest release of the consolidated Ultrix documentation CDROM

of me is nowhere in the disk contents listing does it say which
disk the products appear on. In other words, if I want to read
the documentation for a certain product, I have no way of knowing
which disk to mount.

What is ironic is that the consolidated Ultrix binary CDROM,
which has been a multi-CD release for quite a while, does include
a column in their disk contents listing that shows which CDROM
a product appears on.

This is admitedly not the most serious problem DEC is facing but it
shows that DEC is not communicating internally.

I am writing device drivers for ULTRIX 4.2A and have encountered a 
problem that is either an ULTRIX bug or possible my misunderstanding
the behaviour of a system call.

My driver will occasionally notify an attached user process by sending 
a signal (psignal - SIGURG or SIGSTOP) to the application. The application
is setup to allow and catch those signals (signal()). In the current
test version of the application code, the sending the signal will
cause a simply function to be called which prints a message to the 
screen, then returns.

Here is the problem.

When a signal occurs and the installed function is called during the
execution of:

	if ((err = ioctl(driver, IOCALL, param)) < 0) {
		....
	}

the driverioctl() function is sometimes called TWICE with IOCALL. 
Naturally, this will cause severe problems. 

Can anyone explain why this might be happening?

By poking the right registers you could probably arrange to boot off
a MASSBUS tape drive, if you can find a bootable 9 track tape.  You
might even be able to find in some very old documentation a machine
code program for booting off a UNIBUS tape drive (TU80 or TS11).  The
V4.2 or V4.3 distribution for the 11/780 should come with appropriate
standalone RX02s, so I doubt you'd need to boot off something else.

Subject: Ultrix 4.3 and DMS
Organization: University of North Carolina at Asheville
Date: Mon, 11 Jan 1993 02:02:13 GMT

Been having a hard time with Ultrix 4.3 and DMS.

I installed Ultrix 4.3 on our DMS server Friday.  It works fine.

I installed it on one DMS client Saturday -- and it seemed to work OK.
I had /dlenv0 set up with Ultrix 4.3, SCSI CAM, Motif --
the whole ball of wax.

So, I thought I'd be smart and put a couple of "customizations"
in a few files (etc/rc.local, etc/resolv.conf) in the /dlenv0
area, figuring they would be copied over to the the REAL root
in the /dlclient0 area.

Then I started having real problems.  I'd try the initial
boot and the client would come back with error messages about
missing files in the /sys/conf area.  I went through a couple
of rounds of deleting and re-adding the DMS client and
got similar results, BUT with varying files -- some were
in /sys/conf but files in /tmp were also missing.

I figured I'd messed up my DMS environment area, so I deleted the
whole thing and re-dms-ed it.  This time I didn't touch any
thing in the DMS environment, but now the problem is worse.
Every attempt to install fails.  The client starts and
bombs out when it tries to configure itself on account of
missing files.  I poke around on the client  -- and
sure 'nuf, the files aren't there.  Now, once the client machine
actually did get up to multi-user mode (after complaining
during the configure), but it didn't start the X window server.


Now there are a couple of unusual things happening on
the hardware side.

First, this is a DECstation 5000/25.  Ultrix 4.3 doesn't immediately
recognize the mouse.  As the release notes say
    2.5.1 Personal DECstation 5000 Mouse Configuration
	After an install or upgrade, the mouse for the Personal DECstation
	takes some time to become configured. When the mouse finally comes
	online, you will see a message similar to the following:
		0x54 A V1.0       DEC        VSXXXX-BB - 3884
This message appears at various times during my attempts to the
boot the client under DMS, and I wonder if the unpredictable appearence
could be causing the problem.

Second, our network is in rather sorry state.  Perhaps, some packets
are getting lost.  The DMS client thinks it is creating files,
but it isn't?

How about you other people?  Is anyone else having similar problems?

I'm about ready to call it quits and stay with Ultrix 4.3 on
the server and Ultrix 4.2 on the DMS clients.

You could, of course, spend _NO_ money, and acquire GCC, which is more or less
the be-all and end-all of ANSI-C standard compatibility, from any friendly

vcc does not.

Yes sir!  

I have a VS2000 with 6 MB RAM and an RD54. I did a base installation of
Ultrix 4.2 - just a bare bones Unix with BASIC installation set, the
Comm Utilities subset and the kernel config files.

I also managed to install the complete X11R5 core installation (no
contrib, the basic MIT clients, a display server, headers, libs) and
still had room to spare on the disk (24 MB) to put some useful GNU
stuff - like bash.

To build X11R5 - I NFS mounted a larger disk from a nearby DECStation.

If you want the X11R5 binaries, I can arrage to FTP to them to you to
spare you the TWO AGONIZING days of compiling.

..... Jim Doyle

BTW- I run few local processes on the VS2000 ; I use a 16" mono display
which is quite crisp and does the job of a sluggish XTERM rather well.

Hi netters,
I have soon to install an Everex Laserscript LX EX 0 2510 as printer
for a Dec 5000/240 (Ultrix 4.3) DecServer250 combination on a serial
interface. 

Because I am only used to HP workstations, I have no exact idea what
to put in the /etc/printcap entry, especially in the filter fields
(the 240 only provides entrys for Dec printers in /usr/lib/lpdfilters). 

I looked up the sample printcap entries at gatekeeper.dec.com, as
proposed in the ultrix-FAQ, but there are only two entries, both
regarding HP LaserJets. 
 
Could anybody out there share his printcap entry or any other
experiences he has made with this combination?

Any help would be greatly appreciated; e-mail preferred.

Many thanks in advance, Josef

I seem to have a potentially similar problem w/ 4.3 on

that the mouse and keyboard will work for a while, and then
I will attempt to access an application via the Session Manager
