Hello,
I'm trying to write a script that will loop a sql statement through an external list. Basically, the script enters a loop and runs the sql statement for each entry in the list file. Currently, the script will stop at a cursor where I can then manually enter the SQL statment. This is... (11 Replies)

But I dont want any file name to be passed,I just want to pass the parameter. Is there any way to that??

Hi,
I am writing a script which creates an external table using a shell script. My requirement is like this.
Usage: . ./r.ksh <table_name> - this should create an external table.
e.g . ./r.ksh abc - this should create an external table as abc_external.
How do i achieve this? Please... (5 Replies)
Hi, I'm a it stuck on the below code where a variable is pulled from sqlplus and used in awk. It runs with no errors but still pulls back all records in the input file.
It should pull the max reference from sql plus and then only print those records where the reference value in column 1 is... (4 Replies)

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.
