Subject: Re: Can I salvage an overwritten tar tape?
Organization: Rockwell International
Date: Fri, 14 Aug 92 20:05:38 GMT


I've received many requests for a summary of the responses (on how to
recover a tar tape which has been partially erased by a tar -c commnd).

I deleted the actual messages, but here goes the summary, as best I
can remember:

- Use dd to get the data from tape to disk, then try to manually
  put a tar header on the file, so tar can then extract the data.

- Use mt (with the no-rewind device) to advance past the EOF placed
  by the erroneous tar -c command.  Then use tar repeatedly, until
  a "good" file is found, and tar will recover from there on.

- Use a tape utility (available at an ftp site) which will recover
  the tape.  I'm so sorry, but I don't have the name of the tool.

What's happened is that after posting the question, we were able to
find an acceptable backup of teh data, so we decided to just use it
instead of trying to recover the tape, so I did not test any of the
suggestions above.

Hope this helps the others who had this problem.  I was surprised
to find this is a much more common problem than I expected.

Thanks again to all those who replied.

That's the crux of the problem.  For at least a while I'll have to deal with

  I am also trying to use the lwp libraries.  The man page notes under
bugs:
    Killing a process that uses the non-blocking I/O library may leave
    objects (such as its standard input) in a non-blocking state.  This
    could cause confusion to the shell.

  When I use the non-blocking I/O library, the shell exits immediately
after the program exits, so it looks like something was left funny.

  How does one get around this?  How do I reset things so they will not
be left in a funny state?  (And, why didn't unix just have non-blocking
I/O calls that die with the process instead of a non-blocking state for
the device as this warning implys.)

  I asked our unix system person to ask the hotline at Sun about
this, but the hotline claimed that there was no such product as the
lwp library, and that it was not supported.

The conversion is:

	active power (in W) = complex power (in VA) * power_factor

If you remember your vector math, complex quantities can be expressed
in one of two ways:  either as a magnitude and an angle, or as a real
and imaginary component.  Complex power is a vector quantity, or, as
we EE folks say, a phasor quantity.  The magnitude of the complex
power phasor is measured in VA.  The real component is called active
power, and is measured in watts.


		     /|
	complex	   /  |
	power	 /    |
	(in VA)/      |
	     /        | reactive power
	   /          |
	 / >theta     |		power factor = cos(theta)
	---------------
	 active power (in W)

A power factor of 0.8 is the typical rule of thumb.  So, the UPS
required to support a 1.2KW load would be about 1.2KW/0.8 or 1.5KVA.

If you were to look at the voltage and current signals on an oscilloscope,
you would see that the voltage sine wave is a little ahead of the
current sine wave.  This is always the case when driving an inductive
load, i.e. a transformer.  The power factor indicates the separation
between the voltage and current.  If the time of that delta is called
`d', then the power factor would be cos(2*pi*(d/16.7msec)) where
16.7msec is the period of a 60Hz signal, or pf = cos(377*d).

The faceplate power readings tend to be conservative.  If you want to
measure the actual power loading you need a clamp-on current probe
and a `true RMS' reading multimeter.  Multiply the measured current
by the measured voltage to get the active power in watts.  You need
to throw in a fudge factor to account for both future growth and
startup surge, and then divide by the power factor to size up the
needed UPS.

They shouldn't normally have anything in them.  Notice the "rm *" in the
above sequence.  lost+found is supposed to have lots of unused entries.
When fsck needs to reconnect a file (e.g. you answer yes to the
"RECONNECT?" question) it uses one of these slots.  This is done so that
fsck doesn't have to grow the directory file.

	Oh dear, the automatic device determiner isn't working. It must
be because the Exabyte returns '0' for the density field for the first
mode sense. '0' means a helpful 'default density', rather than the
more useful SCSI-2 code of 0x14 (8 mm helical scan).

Unfortunately, the inquiry data of:

	'EXABYTE 8200SX'

neither matches "EXABYTE EXB-8500" nor "EXABYTE EXB-8200", which is
what the fallback table in 4.1.2 has for exabytes. In previous releases,
the match was against just plain "EXABYTE", but that caused problems
when the 8500 showed up.

If you can't make a new kernel, you're hosed. If you can, edit
the table in /sys/scsi/targets/st_conf.c as appropriate.
I'd also complain to your exabyte rep.

I'd also file a bug at Sun (Hah! fixed in NT! :-;)

Or you can use the AutoRaise X resource for olwm.

OpenWindows.AutoRaise:  True

will pop to the top any window you move the focus to (you should also set the 
resource OpenWindows.SetInput to "followmouse").

Be aware that this can sometimes affect you in ways you don't expect, and if
you have overlapping windows, slight mouse motions can suddenly bring another
window to the top because you went over the edge. "twm" allows you to specify
which applications should be autoraised; olwm does not. However it does have
another resourse, AutoRaiseDelay, which you should be able to use to alleviate
this a bit.

There is also another resource called RaiseOnActivate, which raises the window
as soon as you start to type into it. That might be a good compromise.

daemons.  Not the same thing as demons.

The phrase daemon is not a Sunism, nor for that matter is it a UNIXism.  The
term apparently goes back to the early sixties when they were working on
CTSS, and they appeared in Multics and then UNIX.

The word Daemon is a much older form of demon, and it has no bias towards
either good nor evil.  The Greeks had a concept of a "personal daemon," 
similar to the current concept of a "guardian angel."

Tell you coworker to go look up daemon in a reasonably good dictionary. :-)

This is the behaviour I encountered when my reset signal didn't work

This is considered anti-social behavior and is not supported.

You are strongly encouraged to use a supported application programmer 
interface (API), which on SunView includes:  Pixwin, SunPHIGS 1.x and
GKS 3.x (I think); which on OpenWindows Version 2 includes:  
xlib, XGL 1.x, SunVision 1.0 and PostScript; and which on 
OpenWindows Version 3 includes:  xlib, direct xlib, XGL 2.0, 
SunPHIGS 2.0, GKS 4.1 (I think), SunVision 1.2 and PostScript.

By choosing the right API for your needs, you have an excellent chance of
achieving close to 100% of raw hardware performance.

Among the reasons why direct access is not supported:

- applications which are ported directly to one frame buffer are not
  portable and do not work on any other frame buffer.  Even if the 
  developer is sure this is what s/he wants to do, the customers
  of such applications may think otherwise, except that they often
  assume Sun is at fault, not the developer.  Everybody loses.

- applications which are ported directly to a frame buffer are often
  very difficult to debug, especially with stateful frame buffers
  such as the CG6, which is very unfortunate, because such applications
  are often very buggy.

- different versions of a given frame buffer may have different
  register offsets, etc.  The supported APIs know how to take this
  into account.  A developer with soem arbitrary version of the frame 
  buffer doesn't.  Result:  an application which fails on some versions 
  of a given frame buffer, in which case the customer often assumes 
  Sun is at fault, rather than the developer.  Everybody loses.

- it's a pain to document and support direct access to a stateful 
  frame buffer, especially one with many different flavors and 
  revisions.  Hint:  CG6 fits this category.  Epitomizes it, even.

If you have an application that absolutely must have direct hardware
acess, and you're really serious, you do have the option to pay $75k 
(or whatever) for source and go have a ball.

the reason why the shell is being blown out of the water,
