It is a bad idea to have relative paths in scripts, so i changed ./Generateadd.sh to a call with the absolute path. If you use relative paths in scripts that means the script will work in one directory but not in another.
I've got a dual CPU Itanium server that we use for hosting our Oracle database. It's been up and running fine for quite some time. So well, in fact, that I haven't even looked at 'top' in a while. Recently I needed to look at 'top' and I only see one CPU listed now. CPU0. Is there any other... (5 Replies)
Does anybody know if HP-UX on Itanium always comes with backwards compatibility for PA-RISC applications?
I've heard that there is an emulator called Aries which should do the trick, I just need to know if it always comes as standard with HP-UX Itanium systems.
Any help would be greatly... (3 Replies)
This is definitely a "stupid" question, but I can't think of anywhere else to ask it, so here goes. My knowledge of CPU history on big iron machines starts with the last DEC Alphas, a short stint with Sun servers, PA-RISC and Itanium, Intel 486s on the desktop before that, and Motorola 68000 CPUs...

I have 2 servers , both are HP-UX

According to the press release, Oracle will stop supporting the Itanium platform altogether, including all databases.
Just out of curiosity: what selling-points will there be left for Itanium servers? From personal experience I know that the ports of FLOS software are mostly very out of date... (4 Replies)
Our company developed applications on an HP-UX 11 Itanium system using gcc.
We did not have HP's C/aC++ system installed.
We are now attempting to install/run on a customer system that already has C/aC++ on it.
Can gcc (gcc-4.3.2, or just the runtime libraries gcclib-4.3.2) be installed and... (1 Reply)
Hi Unix and HP-US experts,
I have a need to encrypt/give password to PDF files in HP-UX servers, but unfortunately I am new to unix and hp-ux.
My server is HP-UX 11.31 running on Itanium 64 bit architecture. I have downloaded and installed PDFtk from this link:... (1 Reply)
Hi
I can't download gnome from HP website because links are broken:
I can only download patch for Gnome.
Can you help me?

bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
