I'd imagine it's just an oversite. Add the line:
options SHMPOOL="xxx"
to your kernel config file (/usr/sys/conf/SOMEFILE) and rebuild your kernel;
you might was well change MAXUSER=12 while you're at it.
"xxx" is some number of k-bytes; we use SHMPOOL="8000" to get 8meg
of shared-memory.

we've had the version of the problem to which wnl refers. I've solved the
problem - in the sense that it can only occur when your local partition is
full - by linking /tmp to a tmp file in the user-space. Make sure that
file is public write.

Subject: Re: csh "filec" bug (2)
I've tried similar tests on a variety of Sun-3s and a Vax running Ultrix
2.1. I also tried with the tcsh (version 5.4). My results were similar
to the previous reportings of this error: error on Sun clients (running
3.3 or 3.4) and not on 3/160 servers (running 3.3 or 3.4). An exception
was a Sun-3/260 server running 3.4 which exhibited the same error as our
clients.
As concerns tcsh, the pattern was symetric with my findings above. In
addition, to not doing user-name expansion on clients, it would also
refuse to do "ls ~ralph" when the full name was given. No such problem
exists with our Vax; we have the same source of tcsh installed on all our
machines. The Vax does succeed in using `yp' in order to get user names
on our Suns.
I hope that this supplementary information might be useful to someone who
may look into this problem.

Well, I've never actually used SunCore in a SunView window, but I have
used SunCGI in a SunView window. Appendix F of the SunCGI manual talks
about how to merge SunCGI level and Pixwin level code. Basically you use
the 'cgipw_<command>' instead of the '<command>'.
There are also some functions you need to call to open/close/initialize
cgi to work with pixwins. You wanted an example so here's one that
creates a SunView frame and canvas and draws two rectangles in the canvas,
one with a pw call and the other with a cgi call.
The really confusing thing about using cgi and pw together is that you've
got to fiddle with the order of the open/close/draw function calls. Play
with not closing cgi before you call window_main_loop to get callout
events to use cgi in a pixwin.
Good Luck.

Subject: X11 & suntools on a Sun 3/60C (multiple screens)
There has been some recent discussion on using multiple frame buffers on a
Sun 3/60C. The X11 Rev 2 Sun server will support 2 displays on a 3/60C -
one monochrome and one color. When you drag the mouse off of one screen it
flips to the other. You have two completely different desktops, almost
like having two seperate screens. My question is, if X11 can handle that
is there a way to make suntools or NeWS behave similarly: to have NeWS or
suntools running on different desktops simultaneously, or two instances of
suntools or NeWS, like X11. Someone from Sun should know the answer to
that question. I'd imagine it's possible, with a little hacking maybe?

Subject: Sun 100U Video Problem
I have recently acquired a Sun 100U and it has a video problem. Its
horizontal retrace does not quite reach the top. This results in losing
the top 10-15 raster lines + the part of the screen it scribles across.
Does anybody have schematics or can tell me what the fix for this problem
is? In Sun-spots volume 4 issue 13 there is a follow up by Mark Murray
(MKM at WASHINGTON.ARPA) on some video fixes that he posted. Unfortunately
that is my oldest issue and I cannot seem to reach Mark at the above
address. If somebody could send me a copy of the original article or tell
me how to get in touch with Mark, it would be greatly appreciated (I know,
I know, I'm the only idiot with a hard copy archive that old.;^)

Subject: 4 Fuji-2372's on a single xy451 ?
HELP!
We've just installed 4 Fuji-2372 disks on a Xylogics 451 controller with
an AVIV VME-bus adapter on our Sun-3/280. After formatting up the disks,
installing UNIX and reloading our dump tapes we discovered a very nasty
problem. The problem is that some programs will not run anymore.
Interestingly, if we make multiple copies of the same executable file,
some of them will run just fine. Others however never even make it to
main(), instead they report an EMT trap and dump core. Yet cmp reports
that there are no differences between the executables that work and the
executables that dump core. So, apparently, the executable's position on
the disk affects whether it will run or not ! This problem can be
reproduced consistently on each of the 4 2372's. By the way, no disk
errors are being reported.
We've already replaced the 451, the AVIV adapter, and all the cables yet
the problem still persists. Has anyone out there successfully installed
2372's on a 451 controller on a Sun-3/280 ?

Subject: canvas resizing?
Does anyone know of a way to dynamically resize a canvas? I'm not talking
about the window resizing that one can perform from the Frame menu; I want
to dynamically change the size of the actual drawing surface. I have an
application where I draw something on the canvas, and if the user clicks
on part of what I've drawn, that part can be expanded. Some of these
drawings can get quite large (I've had occasions to create canvases as
large as 8000 by 8000).

Subject: Are there any decent serial boards for Suns?
We need some decent RS232 boards for a Sun 3/280. We have some Systek
(sp?) boards and they suck: they appear to be interrupt-per-char on
output, of all obsolete things, like dz's. On top of that they
periodically cause our Interphase 4200 disk controller to lock up (and
then slowly reset, due to our adding the reset code to the driver). The
latter could be an Interphase bug, not a Systek bug, considering our other
experiences with the Interphase boards and driver (in a word, buggy).
I have heard that Interphase makes a serial board. Anyone used it?
Anyone know of any others? Thanks for any info.

Subject: SDRC I-DEAS Calcomp plotter driver?
We are looking for a plotter driver so we can use a Calcomp 1044GT plotter
on our Suns when we are running SDRC's I-DEAS software (SDRC stands for
Structural Dynamics Research Corporation). The software manuals mention
the ability to compile a plotter driver for the Calcomp plotter, but the
documentation that tries to explain what must be done is very unclear.
I-DEAS only supports one plotter type (when plotting the 3-D picture
files) - Hewlett-Packard. While I like HP equipment, I think Calcomp
provides a much plotter for the money. The 1044GT is a sharp plotter, but
it it is to be unsupported we are send back the evaluation unit and look
at buying a less capable HP [budget is limited]. I-DEAS is pretty sharp
CAD/CAM/CAE, but only supporting one plotter [and they actually support
the older HP models - not even the current ones, i.e., 7585/7586 versus
the DraftMaster I/II.
Anyone from Calcomp read this netnews group and care to help us out with
this?
Any help would be appreciated - leads, tips, etc.
