I was doing an
audit of PUB.SYS and found X.PUB.SYS. What is this file for?
HP's Bill Cadier
contents indicate that it is really
/usr/include/if_arp.h. I found an X.PUB.SYS on my 6.0
system and one on a system that was just updated to 7.0 last week. My
guess is that this file was created on a CSY system in some early
installation testing and we have accidentally propagated it out via
the installation tapes.
Gilles Schipper adds:
This file has
been there at least as far back as 5.5 and probably even before that.
I have renamed this file to x.delete.sys before later deleting it
without any consequences. I seem to recall that it reappears after
each MPE/iX update.
Is there a quick
and dirty way of sorting a text file alphanumerically by the content
of each line?
file of 80 bytes and no defined columns.
of any other filename
Andreas Schmidt adds:
sort.hpbin.sys HFS-filename. For more options see the man page!
When dropping to
the shell and doing a more or vi, I get a
message that reads
history: File too large
What is the
meaning of this message and where do I find this history file?
Rick Clark replies:
The file is
..sh_history. From the shell, type, man history
Ted Ashton adds:
dont want its contents, you should be able to simply remove it
and start afresh.
We installed 2.0.7
Samba when we upgraded to 7.0. Even though I can see the Samba
directories, mine and other users when I do the old map network
drive, I get one of 2 errors: 1) Unexpected network error, or
2) The network name cannot be found. Why?
Lars Appel and
others supply the answers to both:
username must map to a group with the same name on the HP 3000,
otherwise youll receive An unexpected network error
occurred. 2) Windows NT doesnt like more than 12
characters total for the user and account name.
I am building a
new IMAGE data base. What is the number I need to get the record to
fit into. Is it still a multiple of 256?
MPE/iX is a page driven system, I have long maintained the best
blocking factor for IMAGE datasets to be 2,048 words, or a fraction
thereof, like 256, 512 or 1,024.
I have a new 100Mb
card for my 9x9. Ive installed the software, but now I need to
install and configure the card. I cant find any indication of
the physical path of the LANIC (the slot).
The Web knows all.
Tom Turner replies:
There is a
nice diagram in the K-Class IO upgrade manual that labels all of the
slots. Its available online: Go to docs.hp.com and select
browse by topic. Then select System Hardware, then select K-Class
Servers. Then Select I/O Upgrade manual (in PDF format). Its on
page 21 of the manual.
We had a power
failure and the attention light on our N-class is on. What should we
Liz Campbell replies:
You have to
clear the logs - <cntl> b - then sl - view error logs.
What do I need to
know about using the big pin with MPE/iX 7.0? It is
supposed to let the N-Class servers allow more processes to
Guy Paul replies:
Your 7.0 PP1
communicator describes this in the Technical articles section. See
Tracy Johnson then asked, tongue firmly in cheek, What happens
after you pull the Big Pin?]
Will MPE/iX 7.0
run on my 918?
responded that 7.0 will run on 9x8, 9x9, 99x, A- and N-class
Joe Dolliver notes
a word of caution:
check the size of LDEV 1. Many of these systems came with a 1Gb disk
Would a store tape
created on a DLT4000 be able to be restored using a DLT8000 and would
it work the other way around?
and Thomas Root reply:
will be able to read any tape created on a DLT4000. If you use TYPE
III tape, then it will automatically be readable on a DLT4000. If you
use Type IV tape in a DLT8000 then you must force a density switch to
make it readable by a DLT4000 drive.
