2248.0. "Starting Servers ONLY under ULTRIX" by IOUONE::BRYSON () Fri Feb 09 1990 17:44

What is the best way to start a server only on an ULTRIX system?  On VMS,
it is no problem - @DECW$STARTUP SERVER.  On ULTRIX, I have tried the
following entry in /etc/ttys which started the server only but also caused
a cycling init process.
 
:0 "/usr/bin/Xqdsg" none on secure

- and -

:0 "" none secure window="/usr/bin/Xqdsg"
 

Any suggestions??

Just execute it.

# /usr/bin/Xqdsg
2248.2Restart after crashesIOUONE::BRYSONMon Feb 12 1990 17:488
Yes, but I would like it to restart when it crashes (of course, this will
never happen  ;-)), but just in case...  Execution by init from ttys is
what I am looking for.

Thanks,

David
2248.3Should be correctSMURF::COUTUHe who will not risk, cannot win.Tue Feb 13 1990 10:0419
    Your first line:
    
     :0 "/usr/bin/Xqdsg" none on secure
    
    should work correctly. I use this constantly for running tests
    against a 'bare' X server with no other X client applications
    running. Be sure that you have the line in /etc/ttys for the
    console device set to 'off' or else you'll have problems. Of
    course this does assume that you're using a color VAX workstation.
    If you have another type of workstation then you're using the
    wrong X server.
    
    Xqdsg = color VAX (except 3520/3540)
    Xqdsm = mono VAX
    Xcfb  = color RISC
    Xmfb  = mono RISC
    Xgb   = 3520/3540 VAX

2248.4It works, but....IOUONE::BRYSONWed Feb 14 1990 12:555
Yes the line that I gave does work; however, I get a cycling init process
created when I use this line.  I am trying to keep this cycling process from
being created.

    If your login screen is going away and coming back by itself then it is
    a serious problem somewhere in your system. I'd suspsect that maybe
    you have two init processes or else the line in /etc/ttys which starts
    with 'console' is set to on as well as the line starting with ':0'.
    This gives you dueling tty line processes. Check your setup, see if
    you have more than one process named init.

2248.6Must know cpu type?HPSRAD::KOMARYou can't fool NatureWed Feb 14 1990 18:5113
	In an Ultrix environment, one needs to know what type of machine
	(even what type of VAX, gasp) one is using before determining
	what line to put in a file?

		A bit more primative than I would have imagined.

		Isn't there a better way?

	(I don't manage any Ultrix systems, but I had that they would
	 be, uh, easier than these others...)

		-pk.

You need to know what kind of display hardware you have.  That is the extent
of the dependency.

    Re: .6
    
    Well you pay your money and take your choice. ULTRIX doesn't have
    shared libraries like VMS does so our executable images tend to be
    larger. Large files on small workstations are not user friendly.
    Therefore splitting one large X server into several smaller pieces
    makes a lot of sense. You don't have to carry around the baggage of
    things that you'll never use. Keep in mind that all of what we're
    talking about doing in this note is non-standard use of DECwindows. The
    installation process sets things up correctly for normal use and you
    don't have to know about there being more than one X server unless
    you're trying to do odd stuff like we're talking about.
    
    Just because you don't agree with a design doesn't mean that it's wrong.

2248.9Field test software strikes again...IOUONE::BRYSONThu Feb 15 1990 12:588
OK,

Apparently, my system was messed up for a while.  After a reboot, the first
line from .0 worked fine (ah the life of field test).

Thanks,

David
