Install Oracle Instant Client and PHP OCI8 module

If you want to connect to an Oracle database with PHP, you can use Oracle's Instant Client and the oci8 module from pear.

Download the Basic and the SDK packages from oracle.com. At the time of this writing, the filenames are instantclient-basic.zip and instantclient-sdk.zip.

Unzip these files in a new directory, e.g. /opt/oracle/instantclient.

Code:
[bash]
sudo su
mkdir -p /opt/oracle/instantclient
cd /opt/oracle/instantclient
unzip instantclient-basic.zip
unzip instantclient-sdk.zip
echo /opt/oracle/instantclient >> /etc/ld.so.conf
ldconfig
[/bash]

The previous two lines are supposed to create symlinks named libclntsh.so and libocci.so which we will need later. In my case these symlinks were not created by ldconfig, so I created them manually.

Code:
[bash]
ln -s libclntsh.so.11.1 libclntsh.so
ln -s libocci.so.11.1 libocci.so
[/bash]

In the next step we will download the oci8 module with pear. Pear is in the php-pear package.

Code:
[bash]
apt-get install php-pear
[/bash]

Also, you need php5-dev and build-essential packages for compiling oci8 module.

Code:
[bash]
apt-get install php-pear php5-dev build-essential
[/bash]

"Normally" we should be able to just use pecl install oci8 now, but apparently pear is not able to figure out where the instantclient libraries are. So we will just download the oci8 module and build it on our own.

Code:
[bash]
mkdir -p /usr/local/src
cd /usr/local/src
pecl download oci8
tar xzf oci8-1.3.4.tgz
cd oci8-1.3.4
phpize
./configure --with-oci8=shared,instantclient,/opt/oracle/instantclient
make
make install
[/bash]

The oci8-1.3.4.tgz filename will of course change for newer releases.

To enable the oci8 module in the php.ini (/etc/php5/apache2/php.ini and /etc/php5/cli/php.ini), add a line
Code:
[text]
extension=oci8.so
[/text]

(put this line after the examples starting with ;extension).

Now stop and start Apache. You should see the oci8 module in the output of phpinfo().

Good luck

Nested X11 environment session


Hi :)

Instead of using a full-blown new virtual X for developing software you can use Xephyr to embed your KDE 4 session into your working KDE 3 or other X11 environment.



If you want to get a minimal KDE session up and running, just launch Xephyr (available in Kubuntu as xserver-xephyr; Gentoo users compile x11-base/xorg-server with USE="kdrive"):
Xephyr :1 -extension GLX &


You can now launch KDE:
export DISPLAY=:1
/path/to/kde4/bin/startkde &


For other X11 environment just change /path/to/kde4 like:
/usr/bin/startx &

or
/usr/bin/startkde &

or
/usr/bin/startxfce&


You can use "locate" command to find paths like:
locate startkde

Webmin, Installing on Ubuntu Gutsy Gibbon (7.10)

Webmin
Hi :)
I wrote post about Webmin in ITPencil. My Persian friend like it. I decide to write post about Webmin and how to installing it on Ubuntu Gutsy Gibbon (7.10).
It's very good for newbie.

from webmin.com:


Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.



Installing Webmin On Ubuntu Gutsy Gibbon (7.10)
Webmin has some dependency package.
Install dependencies:

sudo aptitude install bash perl libnet-ssleay-perl openssl \
libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl

After install dependencies, you can download and install Webmin. Last version of Webmin is 1.390.
Download Webmin:

sudo wget http://prdownloads.sourceforge.net/webadmin/webmin_1.390_all.deb


Install Webmin:

sudo dpkg -i webmin*.deb


Log in and use it:
Copy this URL into your web browser: https://localhost:10000

Linux and UNIX bash shell aliases

shell
Hi

Commonly used for a long strings that are frequently used. Alias allows you to have a small more familiar command or name to execute a long string.

Set an alias
Syntax
alias [name[='command']







nameSpecifies the alias name.
commandSpecifies the command the name should be an alias for.
-aRemoves all alias definitions from the current shell execution environment.
-tSets and lists tracked aliases.
-xSets or prints exported aliases. An exported alias is defined for scripts invoked by name.
-pPrints the list of aliases.


Examples
alias command with no arguments or with the -p option prints the list of aliases:

$ alias
alias ff='firefox'
alias l='ls -CF'
alias la='ls -A'
alias ll='ls -l'
alias ls='ls --color=auto'
alias sx='startx'


Sets clr to type clear

$ alias clr='clear'


Remove an alias
Syntax
unalias [name]



nameSpecifies the alias name.
-aRemoves all alias definitions


Clear all Linux / UNIX bash shell aliases

$ unalias -a


Note
When the computer is rebooted all alias will be lost.

How to prevent it?
All alias must be added to .bashrc file located at your user folder (example: /home/saeid/.bashrc)

Example

$ gedit /home/saeid/.bashrc

paste:

alias clr='clear'

now you have to 'compile' your .bashrc file

$ source .bashrc

Now clr alias it's saved.

Good luck
