Hi,
Below shell script executes based on liasted data files parameters.But small problem need to avoid ,If any empty line occures in dat files it's throwing oracle error .Need to ignore empty lines (means does not ready by script).Please advice.

Hi Gurus,
I am very new in Unix,
I have 1 script, in which I am truncating the table , then BCP the data in Sybase table, and then loading the data from sybase table to sybase table.
every thing is working fine, but the problem is with Error.
I made some hanges in my insert statement so... (3 Replies)
Hi
Am making connection to oracle using ISQL as shown in the code.
This code is just a minor part of a big code.
I want to capture the error if the password/login is wrong or if connection is not made.
I need to capture the error code also.
Also, If such an error occurs, i need to exit out... (4 Replies)
Hi,
I am using RHEL4 and Oracle11g , my application requires odbc connection
hence I modified ODBC.ini file and when I exceute isql commande I got the following error.

Hi Guys,
I am using simple ls command to find out whether the dir exist there or not. If dir found than remove. But the problem is I don't want the error shown on the terminal window that "dir not found" on the terminal window everytime i execute it. The code I am using is:
set x = `/bin/ls... (4 Replies)
mkdir logs
mkdir: Failed to make directory "logs"; File existsTo avoid this error i use the -p argument so it creates a folder only if it is does not exists like you see below.

Hello Everyone,
Coming again for your help to solve the below error:
In a script, i had created a temp table (Temp_table) and loaded the data in it using bcp command (performed successfully) and I wanted to move it to the preferred table (called Main_table) for further use. hence I have added... (1 Reply)

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.
