My requirement is that I wanted a shell script which should read the alert.log(oracle) and should send the alert to my email if any error encountered on daily basis. I have a script which does the same job but at the same time it creates a new alert.log whenever any error occur. But I don't want the new alert log I wanted to read the same alert log daily and if any new error come should alert as email.

I don't understand the results of a simple performance test I ran using two basic scripts (running on a high end server):
perfVar.zsh :
#!/bin/zsh -f
MYVAR=`cat $1`
for i in {1..10}
[code]...
Performance test result:
> time ./perfVar.zsh BigTextFile > /dev/null
./perfVar.zsh FE > /dev/null 6.86s user 0.32s system 100% cpu 7.177 total
> time ./perfCat.zsh BigTextFile > /dev/null
./perfCat.zsh FE > /dev/null 0.01s user 0.10s system 91% cpu 0.118 total
I would have thought that accessing a VARIABLE was way faster than reading a FILE on the file system... Why this result ?Is there a way to optimize the perfCat.zsh script by reducing the number of accesses to the file system ?

I want to read the file into array and store each line in each index. I've tried using the following code.
Code:
dataarray=($( < file.txt ))
It stores each word in each index rather than each line in each index.
I know that cat can output the file, but how do you store that output in a variable to process:

This doesn't seem to work?

I am new to shell script and to this form as well, I did try to search for a similar post like mine here, but could not find one.
Here is what I'm trying to do:
I am trying to grep server logs to find a specific string and then capture the time stamp and the value of that grep string in them. The log file prints out messages on per sec basis.
My script is able to grep the server logs for the entire period of my load runs and then outputted it to a .csv file too.
Unfortunately this .csv file is too large to extract it on my PC and to generate graphs as it exceeds the excel limit. I need some help on how to read this .csv file in a shell script and then take an average on per min basis before I can export it out on my desktop and generate graphs for analysis. example of the out in my .csv file:
I recently decided to try installing Command & Conquer Red Alert 2 Yuri's Revenge from an old iso file I had floating around my hard drive. I first mounted the iso and copied the files from it into a folder. I then used Wine to install. Everything went according to plan until I went to run the game. When I tried running Red Alert 2 (original) an error message popped up: Error - Unable to set the video mode. When I tried running Yuri's Revenge the same thing happened with one small exception, the first couple of times I tried the Yuri's Revenge splash screen popped up before showing the error message. However the splash screen no longer pops up.

I've AMD64 system with Ubuntu 11.04 installed. It's been rough ride for me to install oracle-xe-universal. I've already spent more than 2 days on this. Still unsuccessful.
1) First I downloaded the packages libaio_0.3.104-1_i386.deb and oracle-xe-universal_10.2.0.1-1.1_i386.deb
2) Then I ran
sudo apt-get install bc (ran fine)
sudo dpkg -i --force-architecture libaio_0.3.104-1_i386.deb (ran fine)
sudo dpkg -i --force-architecture oracle-xe-universal_10.2.0.1-1.1_i386.deb
(gave me dependency error for libc6 (>= 2.3.2), I modified the control file to remove dependency and rebuilt the package) (now worked fine) Oracle xe is now installed. Then I tried to start the DB it started but it's HTTP client never started. So I decided to uninstall the oracle-xe=universal. None of the sudo apt-get remove oracle-xe-universal command's didn't worked for me. So i went for manual uninstallation directions as per oracle link.
I ran the following command-
--Manually uninstalling Oracle 10g--
sudo rm -rf /usr/lib/oracle /etc/oratab /etc/init.d/oracle-xe /etc/sysconfig/oracle-xe /usr/share/doc/oracle_xe /usr/share/doc/oracle_xe_client
Then I again ran the following command to install oracle-xe
sudo dpkg -i --force-architecture oracle-xe-universal_10.2.0.1-1.0_i386.deb
See below what I got as the output-
rocky@ubuntu:~/git/mygit/edas2/libaio$ sudo dpkg -i --force-architecture oracle-xe-universal_10.2.0.1-1.1_i386.deb
dpkg: warning: overriding problem because --force enabled:
package architecture (i386) does not match system (amd64)

Even in applications menu I don't see the if oracle has been installed. So i conclude first time installation was ok but somehow http client didn't worked. After manual uninstallation, second installation didn't even loaded/installed the oracle-xe in init.d directory.

We are trying to install Oracle RPAS 13.1.1 on Redhat Enterprise 5 Linux Server, when we open the directory rpas/rpas/bin, the file DomainDaemon needed to start this server can be seen, but when we try to execute it as ./DomainDaemon it says "cannot execute Binary file", for that reason all files in this directory are giving same message .
We have tried the following :-
a) Given Execute permissions using chmod and run that.
b) Done file DomainDaemon to see if the file is corrupt.
c) Even tried executing using superuser account.
d) The OS and updates required as per Hw&Sw Requirements of RPAS 13.1.1 are there.
e) The directory has Execute Permissions
I am using a backup system with cron + tar. Since the server is very busy, I get often the cron-email: "The file XYZ has changed while reading". This message is a bit annoying and I see it as critical point in my backup system. I believe that this file is then not in my backup. (Is that correct?) Let's imagine the hard disk dies and I have to recover the system and my personal data, and in the night the mysql-table XYZ was not in the backup, because it was in read-usage. I would then have lost this table forever. Is there any way to tell TAR, that it should force the file to be included (if in read-usage, then wait 2 seconds and try again)?
View 9 Replies View RelatedI recently set up a server in my house using Apache 2 running off Ubuntu 10.10 Netbook edition (no, the computer is a desktop). I tried running the website on a few computers in house and all the images and scripts seem to load fine but it is unable to read from the data.xml file through javascript. This leaves all of the web pages empty because all of the content is parsed from the xml file through javascript. I tried debugging with google chrome and after running this code to load the xml file:
if (window.XMLHttpRequest) {
// For IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
}

the xmlhttp.responseXML is null and the script crashes. Could this be a permission issue? I tried setting the data.xml file to read-write permission for any user but that didn't work.
