Tomcat Server Configurations

Add these 2 files to /usr/share/tomcat5/common/lib

ojdbc6_g.2.jar and tools.jar

You wil get ojdbc6_g.2.jar from /u01/app/oracle/product/11.1.0/db_1/jdbc/lib

(or ur $ORACLE_HOME/jdbc/lib)

You wil get tools.jar from /usr/lib/jvm/java-1.6.0/lib

(or $JAVA_HOME/lib)

bash: ls: command not found

Don't Worry

This occurs when you edit your .bashrc file in your home folder
Suppose you edited your /root/.bashrc file as root folder.. Then you will not be able to do any commands.. No other users can change roots file also..

Solution
--------------
Take the terminal
[sarith@acerfedora ~]$ export PATH=/bin or to the path where your ls executable resides
Now you will be able to work with ls command. Come to home folder of the user

[sarith@acerfedora ~]$ export PATH=/usr/bin

Now you will be able to use gedit or vi or any other editor.Edit .bashrc file
Delete the path you added or Add path to all directories like
/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/u01/app/oracle/product/11.1.0/db_1/bin:/home/sarith/bin

Exit the shell.. It started working again.. If any other problems mail me
sarithdivakar@yahoo.co.in

Bash

NAME
bash - GNU Bourne-Again SHell



DESCRIPTION
Bash is an sh-compatible command language interpreter that executes
commands read from the standard input or from a file. Bash also incor-
porates useful features from the Korn and C shells (ksh and csh).

When Bash starts, it executes the commands in a variety of different scripts.

When Bash is invoked as an interactive login shell, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.

When a login shell exits, Bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, Bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force Bash to read and execute commands from file instead of ~/.bashrc.

Customizing the splash image in GRUB

Got bored with corporate logo of your Linux distribution?

Change it..

1.The image should be of size 640x480 pixels

2.Should only have 14 colours

3.In gzipped xpm format

You can use GIMP for these modifications and save it as xpm file. Then gzip and make it splash.xpm.gz

Back up your /boot/grub/splash.xpm.gz and overwrite with your file

Note: You need root privileges

Done! Reboot and watch...

Here is my lap's bootupscreen..

Monochrome images in grey scale, red, blue or green work better than other colours. I used grayscale...

Mounting Windows partitions on CentOS 5

CentOS is an Enterprise Linux distribution based on the freely available sources from Red Hat Enterprise Linux... While installing you have to choose custom layout so that it will dual boot with windows.. In my system Windows XP, Windows Vista and CentOS5 is working together... In order to access data from windows partition and to write data you need to install a software(fuse) and also you need to upgrade your kernel to latest version... For that you can just type(yum update as root)...

Install:
yum install fuse fuse-ntfs-3g dkms dkms-fuse

Then you can mount by:
mount -t ntfs-3g /dev/??? "/mnt/???"

You can check the partition by:
fdisk -l
