After switching to Ubuntu, I tried to install Oracle but no luck until I found this guide from Augusto Bott . He has really written an excellent guide on installing Oracle on different versions of Ubuntu. But again with this guide also the users need to open different files and edit them manually. It isn’t that much difficult but if you are like me who often needs to reinstall/upgrade Ubuntu for one reason or other, reading the whole guide and manually editing the system files is really time consuming and cumbersome. So, to save my time for future installation of Oracle database on my Ubuntu box, I wrote a couple of scripts (four scripts to be exact). Running these four scripts will install Oracle database and will give you a fresh database to start with. To facilitate visual-learners, I’ve also made two videos which have been embedded below. I will explain how to proceed briefly below:

1. Download all four scripts.and unzip them

2. Extract Oracle database downloaded from Oracle to a folder (such as in your home folder)

3. Open 2_OraInstaller.sh in a text editor and change the source/destination values. The default values assume that you have extracted the Oracle installer files in ~/oracle folder and you want to install Oracle db in /opt/oracle folder.

4. Open 4_OraInstaller.sh in a text editor and change the name of your database instance (dbSID). The default is oraIntrepid.

5. Fire up the Terminal and make all the files executable:

$chmod 755 ./1_OraInstaller.sh

$chmod 755 ./2_OraInstaller.sh

$chmod 755 ./3_OraInstaller.sh

$chmod 755 ./4_OraInstaller.sh

6. Make sure you have at least 3gb free space where you want to install your Oracle DB

7. Execute: $./1_OraInstaller.sh

You need to logoff and login once

8. Execute: $./2_OraInstaller.sh

This will install Oracle in silent mode. Please be patient as it will take some time and be very sure that YOU ARE CONNECTED TO THE INTERNET!!!

9. Execute: $./3_OraInstaller.sh

You need to restart you computer once at this point.

10. Execute: $./4_OraInstaller.sh

This will install Oracle database instance in silent mode. This will take about 15 mins so be very patient.

At this point your Oracle installation on your Ubuntu box is complete.

Here are two videos showing all the above steps:

1. Bring up the Volume Control panel by double clicking the volume icon on the top panel. You might see only the Playback tab

2. Go to Edit>Preferences and select Mic Jack, Capture, Internal Mic and click Close

Now you will see three tabs – Playback, Recording, and Switches

3. Go to Recording tab and make sure microphone is not muted.

To select between Internal Mic and External Mic, go to Switches tab and select your preference.

That’s it!

1. I always backup my /etc/X11/xorg.conf file to something like /etc/X11/xorg.conf.bckup
2. When something is broken, I often find that my xorg.conf file has been modified. To find out whether there is any modification, I issue:
   stat /etc/X11/xorg.conf
3. If there is any, I list the changes:
   diff /etc/X11/xorg.conf /etc/X11/xorg.conf.bckup -y –suppress-common-lines
4. I then undo the modifications. Those who aren’t comfortable with command lines can try meld. It is a graphical frontend for diff command. It couldn’t be more easier to merge/remove changes in two versions of same file. It is in the Universe repository so you should get it by issuing:
   sudo apt-get install meld
5. After the modifications have been undone, I restart Hardy. Most of the time I get my xserver fixed with everything working fine – color depth, screen resolution etc.
6. If restarting the system does nothing other than greeting with that dialog box – Ubuntu is running in low graphics mode, then i try to reconfigure xserver by issuing:
   sudo dpkg reconfigure xserver-org
   It will ask you a couple of questions, clicking on default option will be OK
7. After it gives a ’successful’ message, time to restart. I can see the changes immediately – login screen spanning to my whole screen.
8. I need to enable the drivers for my card by going to System>Administration>Hardware Drivers
9. Finally, enabling my nvidia card, restarting once again and going to System>Preference>Screen Resolution to set the correct resolution, gives my pretty looking xserver back again.
10. The next important task is to create the backup of my /etc/X11/xorg.conf file again.

A friend of mine writes “…when I open some heavy sites with Firefox, my Ubuntu desktop gets freeze. I can’t close the Firefox so I find no other way than to restart my system. Aren’t there any other ways to unfreeze the system without restarting?”
Yes there are!


The most efficient way to unfreeze your system is to be patience. Don’t try to open other applications, when your system is not responding. Don’t press unnecessary keys. Go have a cup of coffee, get fresh and get back. You system might have already been unfrozen or a dialog box might be waiting for you to click on that Force Quit button. (I promise you won’t be greeted by BSOD!)

If you don’t have much patience or your system just can’t unfreeze automatically, then follow these steps:

1. Hit Caps Lock or Num Lock keys to see if your keyboard is responding, if it isn’t than you’re out of luck.
2. Press Ctrl+Alt+F2, you will be taken to a black&white terminal window. It will ask you for your username and password.
3. Type the following command to get the PID (process ID) of the program that is not responding (in this example Firefox)
   ps -A | grep firefox
4. It will display you the PID of firefox. You should get at least two PIDs something similar to:
   5961 ? 00:00:00 firefox-2
   5977 ? 00:01:12 firefox-2-bin
5. Now issue the following command to kill the non-responding firefox (its PID is 5977 in this example)
   kill 5977
   [update: If you hate working with numbers you can also kill the non-responding program by issuing: killall firefox-2-bin]
6. Re-check that you have successfully killed the non-responding program:
   ps -A | grep firefox
7. If it doesn’t show you anything, then you are done. To exit and get back to your Graphical System, press Ctrl+Alt+F7

Follow these easy steps (and ask your girlfriend to follow these steps too):

1. Head to http://download.tuxfamily.org/arakhne/pool/ricoh-webcam-r5u870/2.6.22-14-generic/
2. Click on the file ricoh-webcam-r5u870-2.6.22-14-generic_0.10.0-4_i386.deb
3. In the dialog box that appears, select Open with GDebi Package Installer (it is default so you should be able only to click on OK button)
4. In the package installer dialog box click Install Package.
   Done! Finished! But check if your webcam is working:
5. Go to Applications menu (or just press Alt+F1 you lazy fellow)>Add Remove …
6. On the upper right list box labelled Show: ensure All available applications is selected
7. In the search box type: xawtv and select and then install
8. Go to Applications>Sound & Video>Xawtv. You should straightly see your face yourself. Want to show your face to your girlfriend and do chat simultaneously? Follow these steps
9. Head to http://www.skype.com/download/skype/linux/choose/ and click on the link. Again the sametwo dialog boxes should appear. Install using the default option: Open with GDebi Package Installer and then clicking the Install Package on the second dialog box.
10. Go to Applications>Internet>Skype and log in.

Assuming your girlfriend is already waiting you in Skype, call her and enable your video. That’s all!

If you want to see your girlfriend’s face, ask her to follow all the above steps. If she can’t understand you talking so technically (for the first time in her life), send her a link to this blog. I swear I won’t ask her email id. I swear!
