Oracle XE Part 2

Hi All,

Last post I had explained how to install Oracle XE for your distros.

Next part - that is this part - I explain how to configure further for proper working of the database.

1. Issue this command as root : /etc/init.d/oracle-xe configure
2. Once the steps for the above step 1 is done (Refer my last post on Oracle XE)
3. You would have given the password for system / sys - which is the main DBA.
4. Go to your Gnome Menu / K Menu and then under Oracle Database 10g Express Edition -> Go to ->> Go to database home page and there issue the login and password for "system".
5. You can create a new user - once you login in step 4.
6. Now from here on - use "Run SQL command line" from the same menu for connecting and working your DB problems.

3 Cheers :)

Hope all understood what I meant. Mail me for any doubts.

PowerISO and .daa

Hi All,

Ever came across a .daa file extension???

If yes - then hit your browsers to www.poweriso.com

For Linux distributions - hit this link - http://www.poweriso.com/poweriso-1.3.tar.gz

Extract the zip file and for operations / usage of PowerISO - try this command - ./poweriso - ?

Now coming to the .daa file extension - the expansion of .daa is "Direct Access Archive" and this file extension is a proprietary of PowerISO.

You can extract the content of a .daa file using the above linux based free tool - with this command:

./poweriso  extract filename.daa -od /home/username/

You can also convert a .daa file to an .iso file.

Thats it...

Enjoy archiving / extraction,

Oracle 10g

Hey All,

This post explains how to install Oracle 10g onto your systems.

Note: I will be explaining the installation procedure for Oracle XE aka, Oracle Express Ed is the student edition which is free for personal use and not for business use.

Follow these steps:

1. http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
2. Go to that above site and accept the license.
3. Search for "Oracle Database 10g Express Edition" and click on the link below with this text : Oracle Database 10g Express Edition for Linux x86  
4. If your distro is a Red hat based - like - Fedora, RHEL, Red Hat 9, openSUSE, Mandriva - then download the .rpm file. 
5. If your distro is a Debian based - like - Ubuntu, Linux Mint, Sidux etc - then download the .deb file.
6. For installation its simple:
a. for the rpm file: rpm -i filename.rpm
b. for the deb file: dpkg -i filename.deb
7. Make sure that you resolve the dependencies if any.

Post install configuration:

1. Go to /etc/init.d
2. As root - issue this command: ./oracle-xe configure
3. Mention the port number then
4. The listener port number and other details.

Add your a/c to the dba group.

Thats it. You may now check your database page by hitting your browser to: http://127.0.0.1:8090/apex/

This above 8090 is the port number you enter in the 3rd post install step.

3 Cheers :)
Hope you all understood the installation procedure.

Pronounce Debian

Hi All,

Pronunciation is such an important thing in life. For example if people pronounce your name in a different way/manner - its so annoying. Forget the nick names people keep for everyone - but the correct name's pronunciation has to be perfect.

At least this is what I expect out of you.

Now the whole point of this blog post... I met one of my AProf who had no clue as to how to pronounce Debian. He kept on calling it as Debiani or something very weird.

But next time I meet him - I will expect the proper way of calling for my OS.

Adriane Knoppix

Hi All,

Today I downloaded Adriane Knoppix - an approximately 700Mb file.

Its best features being - the full Distro is an Audio based one or a talking menu system - which according to Knopper, helps the visually disabled.

Read here:

A.D.R.I.A.N.E. (Audio Desktop Reference Implementation And Networking Environment) is a talking menu system, which is supposed to make work and internet access easier for computer beginners, even if they have no sight contact to the computers monitor. A graphical environment with also talking programs and arbitrary magnification using compiz-fusion, is another option. 

Try it out to know more... :)

MS Azure

Hi All,

Today I could discuss about cloud computing projects with my students. One of the project seems to use MS Azure.

I very well knew that MS Azure was not free. Check the below link.

I think that the students have to change to something else that open source and free and as well flexible to use.

Think twice before using MS products,

Monodevelop

Hi All,

Today was my first day at NIE as a lecturer. I learnt many new things from my students and of course from my faculty.

I taught some things as well. One of them being about Sharpdevelop.

A sharpdevelop version in Linux is Monodevelop - a GTK based version.

Installing monodevelop is pretty simple.

1. Have your repositories up to date.
2. Use synaptic, search for monodevelop and install it.

Thats it.

But what is MonoDevelop??? Read below "as is" from their site http://monodevelop.com/

MonoDevelop is an IDE primarily designed for C# and other .NET languages. MonoDevelop enables developers to quickly write desktop and ASP.NET Web applications on Linux, Windows and Mac OSX. MonoDevelop makes it easy for developers to port .NET applications created with Visual Studio to Linux and to maintain a single code base for all platforms.

Main Menu

Hi All,

Many a times though we install new packages / softwares - we will not see the shortcuts to them in the main menu.

This post solves that problem.

1. Check if that package is installed or not using gnome-terminal and typing that command.
2. For example if you installed amarok - a music player - and did not find it in the menu bar (Start Menu) -  then follow from step 3
3. Go to System -> Preferences -> Main Menu
4. There under Sound and Video -> Amarok (check box)
5. Check that check box stated in step 4

This step 5 automatically adds Amarok on the menu.

Safe umount

Hi All,

Most of us dont do a safe un-mount or rather a umount.

And most of us use XP - the door OS ;) 

This above leads to a peculiar problem for the pen drive - when its mounted in Linux - and also if the partition is of NTFS type only.

We will not be able to mount the ntfs partitions during this time.

There is a package called ntfsprogs using which we can solve this issue using the below command:

ntfsfix /dev/mount_point

This above command resets the ntfs journal file.

[Try this at your own risk.]
