HOWTO: install Oracle-XE in Mint 4.0 KDE CE  

Although this is a very specific HowTo, except the installation of the package, the other steps are identical in all Linux distributions.

Step 1: go to the official oracle-xe site, and download the package. Because we want to install it on Mint, we download the deb package, oracle-xe-universal_10.2.0.1-1.0_i386.deb. In order to download the package, you'll have to register, but fear not, it's free :). Then, before installing this package, in the package manager install libaio, because in order to install oracle-xe this package must be preinstalled. Libaio can be installed using Adept, only run this package manager, type in the search bar libaio, click request install, click apply, and it's done.

Step 2: Now we are going to install oracle-xe-universal_10.2.0.1-1.0_i386.deb. This cannot be done using Adept, because this package cannot be found in Ubuntu or Mint's repositories because is proprietary software.

So, double click on oracle-xe-universal_10.2.0.1-1.0_i386.deb, and KPackage will appear. You will get a screen like this one:


Click on Install, and wait for a moment for the installation process to finish.

Step 3: Open Konsole, type su, and enter the root password. Next, type /etc/init.d/oracle-xe configure and press enter. The next text will appear:

This will configure on-boot properties of Oracle Database 10g Express
Edition. The following questions will determine whether the database should
be starting upon system boot, the ports it will use, and the passwords that
will be used for database accounts. Press to accept the defaults.
Ctrl-C will abort.

Next, it will ask for a port number, which will be used to access oracle-xe, so change the default one (which is 8080) with the desired one, e.g. 5050:

Specify the HTTP port that will be used for Oracle Application Express [8080]:5050

The next port number can be left the same, which is used for the database listener. So instead inserting a new number, just press enter, and leave the default one (which is 1521).

Specify a port that will be used for the database listener [1521]:
Specify a password to be used for database accounts. Note that the same
password will be used for SYS and SYSTEM. Oracle recommends the use of
different passwords for each database account. This can be done after
initial configuration:

So, enter the password, and after that it will ask You again for confirmation, so enter it again. The last input is whether to start or not the database service at startup.

Do you want Oracle Database 10g Express Edition to be started on boot (y/n) [y]:y
Starting Oracle Net Listener...Done
Configuring Database...Done
Starting Oracle Database 10g Express Edition Instance...Done
Installation Completed Successfully.
To access the Database Home Page go to "http://127.0.0.1:5050/apex"

And it's done. New icons should appear in the menu, meaning something like this:


Step 4: Click on 'Go To Database Homepage' login with the account SYS, and with your entered password. When you login, you can create more accounts, with different passwords, and different restrictions. For more tricks and tips on working with Oracle XE here is a nice official tutorial.

Life Saviour: Root Actions Servicemenu  

In case you use Kubuntu, Mint KDE edition, Mandriva, or another KDE based desktop, 'Root Actions Servicemenu' allows admin users to perform several root only actions from Konqueror (the KDE file/web browser). That is a very good thing, not everybody likes to use Konsole/Terminal.

Lets take a look at it now:


Infact, this works with all distros that have sudo/kdesu installed and that the user is authorized to use sudo/kdesu. The installation is pretty simple, there are three *.desktop files in the archive that need to be placed in ~/.kde/share/apps/konqueror/servicemenus and one script rootactions-servicemenu.pl which needs to be pasted in /usr/local/bin or /usr/bin. I prefer in /usr/bin. Note, if you want all of the users to have the menu, copy the three *.desktop files in /usr/share/apps/konqueror/servicemenus instead.

When a folder is selected, the service menu gives the following options:


Open With - opens the selected item/items with a program of our choice;
Copy/Move/Rename/Delete - basic file operations, but in ROOT mode, so be carfeul;
Ownership to Root - changes ownership of the selected items to root:root;
Ownership to Active User - changes ownership of
the selected items to current user e.g. martin:martin;
Ownership to ... - changes ownership of
the selected items to a UserID:GroupID which we want;
Change Permissions - changes permissions of the selected items;
Open Terminal Here - opens a terminal session in the folder we are located in ROOT mode;
Open in File Manager - opens Konqueror but in ROOT mode, meaning there are no restrictions;

When a file is selected,
the service menu gives the following options:


Open as Text - opens the selected item/items in Kate (the default text editor)
Open With - opens the selected item/items with a program of our choice;
Copy/Move/Rename/Delete - basic file operations, but in ROOT mode, so be carfeul;
Ownership to Root - changes ownership of the selected items to root:root;
Ownership to Active User - changes ownership of
the selected items to current user e.g. martin:martin;
Ownership to ... - changes ownership of
the selected items to a UserID:GroupID which we want;
Change Permissions - changes permissions of the selected items;

To download this great menu, go to kde-apps.org. There you can also post comments, suggestions, submit a translation (although there are a lot of translations already) and get help if needed.

For Mandriva users, there is a similar RPM package, so you don't need to copy all those files... Just install the package 'openasroot-kmenu'.

NEWS: Linux MINT 4.0 KDE CE Released  

The latest edition of Mint, in KDE flavor, in it's Community Edition... The download links are available, as well as the release notes. Here is the announcement:

Linux Mint 4.0 KDE released. Daryna KDE is nearly as 'minty' as the main edition now. The packages are (safely) up to date and the kernel is the Ubuntu Gutsy Gibbon kernel 2.6.22. Mint applications: mintInstall, mintwifi, mintUpdate, mintAssistant, mintUpload. Minted versions of Firefox, Sunbird. Changes since the beta release: fixed the HAL USB NTFS problem; changed some Compiz default settings to make it more KDEish and fix a known bug; added a Linux Mint user agent to Konqueror and pre-added some sites to use the Mint user agent. This helps people know Linux Mint is out and about.

When the DVD (yes this one comes on a DVD, and is 1GB) is booted, the following screens appears:


In the Main edition everything was greenish, but here everything is blueish, which gives a better feel. When booting, tree options are given, to boot the DVD in 'normal' and safe mode, and to boot the HDD (meaning to skip the DVD). The bootsplash is simple, infact, all of the artwork is simple, but it's nicer. The default window decoration is 'Domino' and the default window border is 'Crystal'. That is a very nice combination indeed. So, lets install the Mint.


A lots of languages are available in which the installer is localized:


Now find yourself in the world ;)


Is asks for keyboard layout, and if manual partition setup is selected, this nice screen will appear. One thing I don't know, is this installer the same as in Ubuntu, or is it ported in QT? Nevertheless it does it job as it should.


When the installation finishes, you can remain in the Live Session, or restart and take a look at the newly installed Linux distro.


MINT features KDE 3.5.8, and Linux kernel 2.6.22. These are not the newest packages, but are pretty stable, which is more important. Homebrew Mint packages are: mintInstall, mintWiFi, mintUpdate, mintAssistant, and mintUpload. Ohter highlights in the default applications are: Internet: Firefox, KFTPGrabber, KGet, Kopete, Krdc, Krfb, KTorrent, Thunderbird, and so on... Graphics: digiKam, GIMP, Gwenview, Hugin panorama creator, Inkscape, KPdf, Scribus... Multimedia: AmaroK, K3b, k9copy, Kaffeine, KAudioCreator, KMix, KsCD and MPlayer.


MPlayer and Kaffeine are here for video playback, and AmaroK is for all of the audio filetypes. Almost all multimedia formats are playable. So, next, in Office: HPLIP Fax Utility and Fax address book, KArm, KMyMoney, KNotes, the whole OpenOffice.org suite, and an Online Dictionary.


OpenOffice.org in the latest stable version, 2.3. And, now, lets continue, in Settings: Compiz, Enable KWin, Emerald Theme Manager, mintInstall, Ndiswrapper, and so on... in System: Adept, Envy, HPLIP Toolbox, kbluetooth, KCron, Keep, KInfoCenter, Konsole, Kpackage, kpowersafe and so on... in Utilities: Ark, Filelight, KArm, Katapult, Kate, KJobViewer, Skim and lots more.... I also liked that Java was preinstalled here, and I'm glad to see that Envy is still here, to take care of installing nVidia drivers without fuss.

Mint Offers a healthy package selection, and for the average desktop user, everything is given. The packages are not the newest/beta/rc but are the latest stable ones, which is also a big plus. Another thing that I liked is that the Filelight was associated in the file browser.


So, on whichever folder you like, right-click it, and open it in Filelight, to have it analyzed. To sum up, this is a really nice Community Edition, and if you are in search of a new desktop replacement for your Linux PC, give this one a try, it wont dissapint you. But if you want commercial support, try the Main edition. Imagine Kubuntu, with everything it misses included, well, Mint 4.0 KDE CE it the answer.

NEWS: SLAX 6.0.2 Released  

So, here is the new release announcement:

What is the point of a new release every week? Well, I guess there is none. If you don’t need it, don’t download it :) The version 6.0.2 fixes several bad bugs introduced by the previous release, and it also adds patched Gtk+2, to fix the konqueror+flash hangups. So now you can watch this youtube’s video in Slax as well, just to celebrate with me that I’ve just lost $17000 on forex thanks to InterbankFX’s idiotic rules.

As stated, this release compared with the previous one (6.0.1) features several bugfixes. The downloaded iso image is 192.2MB, and when it's booted the following screen appears:


Several options can be seen, Graphics Mode which loads KDE 3.5.9 as the default desktop, the second options copies the whole SLAX to RAM, Vesa mode, Text mode, and Memtest, which tests your system RAM.

If Graphics Mode is selected, the following screens will appear soon:


As seen, except the wallpaper, almost everything seems the same as in Slax 5 at first sight. The same applications are here, Juk, Kopete, K3B etc... The KDE theme remains unchanged (why?), it seems that the developers don't want or don't have time for wasting on eye candy. But that's not a problem, kde-look.org is always here ;)

Modules are easily added, although there aren't many, the key ones are here. The Slax Module Manager is the package management system, and installing modules is very easy, just download a module from HERE, click Add a new Module, find it, and it's done. NOTE, currently the modules page is in development and only four modules are available, Firefox, Thunderbird, Krusader and Wine. We all hope that this page will have more healthy selection soon.


And, in the end, some stats. Linux Kernel 2.6.24 is used, KDE 3.5.9 is featured, and (almost) all of the default desktop applications are KDE based. They are: the most important first, Internet: Konqueror, KMail, Kopete, Akregator, Krdc, Krfb, KNetAttach; then in Games: KBattleship, KBounce, Patience; Graphics: Kuickshow, KolourPaint, KSnapshot, KColorChooser; Office: Word, KPresenter, KSpread, KPDF, Kontact; in Utilities are found: KCalc, Kjots, KWrite, Ark, KNotes, Klipper; and finally in System: KInfoCenter, KSysGuard, KDE Printer and the Slax Module Manager. It's a nice set of applications for a 192MB.

Although a lot of improvement is done since SLAX 5, and a lot of bugs are fixed, I think that a lot of improvement is still needed. Multimedia features are still lacking although it played all my video files, hardware support is OK, but (as some people say) some specific dirvers aren't found by default. I tried it in VirtualBox and on a standard Office P4 PC, and everything worked fine (when it comes to hardware recognition).

It's a nice distro, and it's easy customizable, but when it comes about customization, there will be another post/howto about that ;) I recommend SLAX to everyone who wants a light KDE based Live CD.

NEWS: Parted Magic 2.1 Released  

If, you are tired of reading, and only for the screenshots, it's Okay, the important thing you should know compared between PM2.1 and PM2.0 is that this release is mainly bugfix release. It features: Linux kernel 2.6.24.2, NTFS-3G 1.2216, VisParted is now able to create ext4 partitions. Bugs are fixed, and drivers have been added.


Parted Magic comes in Live CD, USB, and PXE. Here the Live CD is tried. When you boot the disk, the image above is given.


After booting, you can notice the XFCE desktop enviroment. PM 2.0 featured GTK+ H20 theme, but in 2.1 is replaced with Clearlooks.


This CD is a tool for managing disk partitions, and for this feature, VisParted does the job. VisParted is a fork of GParted, and is improved by the lead developer, Patrik. You can create, restore, backup and delete partitions. Supported file systems are: forext2, ext2, ext3, ext4, fat16, fat32, hfs, hfs+, jfs, xfs, inux-swap, ntfs, reiserfs, and reiser4.


Besides VisParted, lots of other tools are included. One of them is Test Disk, which is used for scanning and repairing partitions. There is also a tool to create a Live USB, but, you should know that, for a Live USB to boot, the PC should be able to boot USB drives. Other tools included are Partition Image, List Partition Table, Test Disk, PhotoRec, Iso Master, Conky, Galculator, Hardware Lister, Save Files, Find Utility and so on..

If you wish for a complete list of all of the programs found in Parted Magic (X based, and Command Line Based ones), go HERE.


The package management system is simple and in 7zip compression, and adding new programs is much more easier. Besides the tools for managing partitions, new programs found here (and in 2.0) are: Start Network, Firefox, Grsync, and lftp.


Start Network is used to establish a working connection, to configure the LAN, etc. It's a simple and powerful tool. Also, Firefox is included, for web browsing, and it's a nice touch. My overall impression is really good, and I think that everyone who reinstalls their operating system once in a while needs this disk.
