Dear all
I've downloaded Solaris 10 from Sun's website. The Operating system installation files are on 4 CD's. I boot with the first CD and start the installation. Then it reboots and start the installation al over again. If I take the CD out during the 1st reboot, then it cannot continue... (3 Replies)

Hello Unix Gurus,
Does anybody have an idea on how to verify packages exist on a remote or ftp server connected through http. Here is my task at hand. We have a central repository in which we retrieve our packages. eg. http://packageserver/packages. What i have done is compiled a list of... (2 Replies)

Hello guys, I am trying to install oracle grid infrastructure 11.2 on Solaris 5.11.
while I was reading the installation guide to check for the software requirements, there were two packages mentioned for the Solars 5.11. They are as follows

Hello Experts,
I need your inputs to figure out the issue I faced post applying Linux patch.
Question:
As a part of change implementation UNIX team applied patches and upgraded OS from version SuSE Linux 11.2.3 to 11.3.6. Post upgrade we could bring up Tomcat successfully; however... (0 Replies)
Hi,
This question is not for troubleshooting, but want to get some clarification. In few of our Solaris-10 x86 servers, there are no SUNWaccu and SUNWless packages, so sar is not present. These are old servers, so not sure, when and how these were build.
Now, there is a big push from application... (1 Reply)

bup-margin
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.
