Miscellaneous (LONG)

[Chris Rende]

I have a Nixdorf Targon/35-M50 running TOS.3.2 which I'm told is
a Pyramid 9810 running OSX 4.0. My background is with System V Release 2.

Here is a list of questions and observations which I've been gathering
over the last month:

If anyone has answers to any of the following or can shed any light on
them, please let me know.

------------------------------------------------------------------------

Nixdorf tells me that TOS.3.3 will be out soon (which is OSX 4.4).
What are the major differences/bug fixes/enhancements/etc... between
OSX 4.0 and OSX 4.4 (or TOS.3.2 and TOS.3.3).

Are there any plans to move up to System V Release 3?

What affect does dk_enable=1 have on performance when enabled?
   (/usr/sys/conf/param.c)
I suppose that "dkstat -a" won't be completly usefull with dk_enable=0...

I've noticed that the following man pages are munged: chmod.2, utmp.4, signal
Does anyone have un-munged ones?

What exactly is sendmail and what can it give me?
Currently, I use SMAIL and PATHALIAS and my System V mailer.

The machine comes with documentation which is System V based.
Is there any BSD documentation? (Aside from the man sheets).
Nixdorf tells me they have none. How about Pyramid?

When I run "mailx -s", mailx passes the -s to /bin/mail which doesn't
like the -s. What is wrong?
"mailx -s" worked OK on my previous System V box...

Our file systems mkfs'ed with 16K block sizes. I don't suppose this can
be changed without re-mkfs'ing and reloading... can it? I didn't think so. :-(
(I'd like to change it to 2K).

How does the ucb UUCP package compare to the att UUCP package?

How does the ucb INIT package compare to the att INIT package?

I had to "chown uucp /usr/lib/uucp" to get it to work.

My TOS release (3.2) is missing 99% of /usr/lib/terminfo/*. How/where can
I get the rest of what belongs there?

I can't get adb or sdb to work at all. I get some type of error message
about a table being the wrong or old format. dbx does seem to work.

I had trouble with expire when I installed it. The man sheet makes
reference to a command like "expire -e 999999 -E 999999 -r". When I run
this, I get floating exceptions because of the 999999. So, I use
9999 instead.

How is the AAU used by the system? Does a ld have to be done with a
special math library? Does anyone know if TDE makes use of the AAU?

In order to get shl to work I had to create a /dev/sxt directory and
"ln /dev/sxt000 /dev/sxt/000" and so on for 001, 002, 003, etc...

Here's an odd error message I recieved once while running ps:
"ps: error locating command name for pid 13216 from Thu Jul 13 14:07@ Q"

What does this message mean from du:
"du: warning - There are more than 1000 linked files"
I've gotten this message in places where there weren't 1000 link files around.

What is the "Commercial instuction set" board?
What is the "Address generation unit"?

I wrote a test program that just allocates large blocks of RAM. It seemed
to let me allocate an amount of memory that was limited by the amount of
RAM in the system. This program also seemed to have a "bad effect" on
performance.
- Does this machine use virtual memory? Seems not to since I was limited
  by physical RAM size.
- Does this machine do paging of individual RAM pages? Or, is all of the 
  processes memory swapped in and out?

When I issue the command "ps" or "ps -f" I get memory faults. But, "ps -ef"
works.

"fuser" doesn't work.

"sar" reported an average of "-20647" for kchar/s.

I got the following output from dkstat:
(Note negative numbers)
