Xenlism WildFire: Minimal Icon Theme For Linux Desktop
|
||||
================================================================================
|
||||
|
||||
|
||||
It’s been some time that I covered an icon theme on It’s FOSS. Perhaps because no theme caught my eyes in recent times. There are a few which I consider the [best icon themes for Ubuntu][1] but these are mostly the known ones like Numix and Moka and I am pretty content using Numix.
|
||||
|
||||
But a few days back I came across this [Xenslim WildFire][2] and I must say, it looks damn good. Minimalism is the current popular trend in the design world and Xenlism perfects it. Smooth and tranquil, Xenlism is inspired by Nokia’s meego and Apple iOS icon.
|
||||
|
||||
Have a look at some of its icons for various applications:
|
||||
|
||||
|
||||
|
||||
Folder icons look like:
|
||||
|
||||
|
||||
|
||||
Theme developer, [Nattapong Pullkhow][3], claims that the icon theme is best suited for GNOME but it should work fine with Unity, KDE and Mate as well.
|
||||
|
||||
### Install Xenlism Wildfire icon theme ###
|
||||
|
||||
Xenlism Theme is around 230 MB in download size which is slightly heavy for an icon theme but considering that it has support for a huge number of applications, the size should not be surprising.
|
||||
|
||||
#### Installing in Ubuntu/Debian based Linux distributions ####
|
||||
|
||||
To install it in Ubuntu variants, use the command below in a terminal to add the GPG key:
|
||||
|
||||
sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 90127F5B
|
||||
|
||||
After adding the key, use the following commands:
|
||||
|
||||
echo "deb http://downloads.sourceforge.net/project/xenlism-wildfire/repo deb/" | sudo tee -a /etc/apt/sources.list
|
||||
sudo apt-get update
|
||||
sudo apt-get install xenlism-wildfire-icon-theme
|
||||
|
||||
In addition to the icon theme, you can download a matching minimal wallpaper as well:
|
||||
|
||||
sudo apt-get install xenlism-artwork-wallpapers
|
||||
|
||||
#### Installing in Arch based Linux distributions ####
|
||||
|
||||
You’ll have to edit the Pacman repository. In a terminal, use the following command:
|
||||
|
||||
sudo nano /etc/pacman.conf
|
||||
|
||||
Add the following section to this configuration file:
|
||||
|
||||
[xenlism-arch]
|
||||
SigLevel = Never
|
||||
Server = http://downloads.sourceforge.net/project/xenlism-wildfire/repo/arch
|
||||
|
||||
Update the system and install icon theme and wallpapers as following:
|
||||
|
||||
sudo pacman -Syyu
|
||||
sudo pacman -S xenlism-wildfire
|
||||
|
||||
#### Using Xenlism icon theme ####
|
||||
|
||||
In Ubuntu Unity, [use Unity Tweak Tool to change the icon theme][4]. In GNOME, [use Gnome Tweak Tool to change the theme][5]. I presume that you know how to do this part, but if you are stuck let me know and I’ll add some screenshots.
|
||||
|
||||
Below is a screenshot of Xenlism icon theme in use in Ubuntu 15.04 Unity. Xenlism desktop wallpaper is in the background.
|
||||
|
||||
|
||||
|
||||
It looks good, isn’t it? If you try it and like it, feel free to thank the developer:
|
||||
|
||||
> [Xenlism is a stunning minimal icon theme for Linux. Thanks @xenatt for this beautiful theme.][6]
|
||||
|
||||
I hope you like it. Do share your views on this icon theme or your preferred icon theme. Is Xenlism good enough to change your favorite icon theme?

Red Hat CEO Optimistic on OpenStack Revenue Opportunity
|
||||
================================================================================
|
||||
Red Hat continues to accelerate its growth thanks to an evolving mix of platform and infrastructure technology revolving around Linux and the cloud. Red Hat announced its second quarter fiscal 2016 financial results on September 21, once again exceeding expectations.
|
||||
|
||||
|
||||
|
||||
For the quarter, Red Hat reported revenue of $504 million for a 13 percent year-over-year gain. Net Income was reported at $51 million, up from $47 Red Hatmillion in the second quarter of fiscal 2015. Looking forward, Red Hat provided some aggressive guidance for the coming quarter and the full year. For the third quarter, Red Hat provided guidance for revenue to be in the range of $519 million to $523 million, which is a 15 percent year-over-year gain.
|
||||
|
||||
On a full year basis, Red Hat's full year guidance is for fiscal 2016 revenue of $2.044 billion, for a 14 percent year-over-year gain.
|
||||
|
||||
Red Hat CFO Frank Calderoni commented during the earnings call that all of Red Hat's top 30 largest deals were approximately $1 million or more. He noted that Red Hat had four deals that were in excess of $5 million and one deal that was well over $10 million. As has been the case in recent years, cross selling across Red Hat products is strong with 65 percent of all deals including one or more components from Red Hat's group of application development and emerging technologies offerings.
|
||||
|
||||
"We expect the growing adoption of these technologies, like Middleware, the RHEL OpenStack platform, OpenShift, cloud management and storage, to continue to drive revenue growth," Calderoni said.
|
||||
|
||||
### OpenStack ###
|
||||
|
||||
During the earnings call, Red Hat CEO Jim Whitehurst was repeatedly asked about the revenue prospects for OpenStack. Whitehurst said that the recently released Red Hat OpenStack Platform 7.0 is a big jump forward thanks to the improved installer.
|
||||
|
||||
"It does a really good job of kind of identifying hardware and lighting it up," Whitehurst said. "Of course, that means there's a lot of work to do around certifying that hardware, making sure it lights up appropriately."
|
||||
|
||||
Whitehurst said that he's starting to see a lot more production application start to move to the OpenStack cloud. He cautioned however that it's still largely the early adopters moving to OpenStack in production and it isn't quite mainstream, yet.
|
||||
|
||||
From a competitive perspective, Whitehurst talked specifically about Microsoft, HP and Mirantis. In Whitehurst's view many organizations will continue to use multiple operating systems and if they choose Microsoft for one part, they are more likely to choose an open-source option,as the alternative option. Whitehurst said he doesn't see a lot of head-to-head competition against HP in cloud, but he does see Mirantis.
|
||||
|
||||
"We've had several wins or people who were moving away from Mirantis to RHEL," Whitehurst said.

How To Upgrade From Oracle 11g To Oracle 12c
|
||||
================================================================================
|
||||
Hello all.
|
||||
|
||||
Today we will go through how to upgrade from oracle 11g to Oracle 12c. Let’s start then.
|
||||
|
||||
For this, I will use CentOS 7 64 bit Linux distribution.
|
||||
|
||||
I am assuming that you have already installed Oracle 11g on your system. Here I will show what I did when I installed Oracle 11g.
|
||||
|
||||
I select “Create and configure a database” for Oracle 11g just like below image.
|
||||
|
||||
|
||||
|
||||
Then I select “Desktop Class” for my Oracle 11g installation. For production you must select “Server Class”.
|
||||
|
||||
|
||||
|
||||
Then you must enter all the paths for the Oracle 11g and your password as well. Below is mine for my Oracle 11g installation. Make sure you meet the Oracle password methodology for placing your password.
|
||||
|
||||
|
||||
|
||||
Next, I set Inventory Directory path as below.
|
||||
|
||||
|
||||
|
||||
Till now, I showed you what I had done to install Oracle 11g as we are going to upgrade to 12c.
|
||||
|
||||
Let’s upgrade to Oracle 12c from Oracle 11g.
|
||||
|
||||
You must download the two (2) zip files from this [link][1]. Download and unzip both files to the same directory. Files names are **linuxamd64_12c_database_1of2.zip** & **linuxamd64_12c_database_2of2.zip** respectively. After extracting or unzipping, It will create a folder called database.
|
||||
|
||||
Note: Before upgrading to 12c, make sure you have all the necessary packages installed for your CentOS and all the path variable are OK and all other prerequisites are done before beginning.
|
||||
|
||||
These are the following packages must be installed with correct version
|
||||
|
||||
- binutils
|
||||
- compat-libstdc++
|
||||
- gcc
|
||||
- glibc
|
||||
- libaio
|
||||
- libgcc
|
||||
- libstdc++
|
||||
- make
|
||||
- sysstat
|
||||
- unixodbc
|
||||
|
||||
Search for your correct rpm version on the internet.
|
||||
|
||||
You can also combine a query for multiple packages, and review the output for the correct versions. For example:
|
||||
|
||||
Type the following command to check in the terminal
|
||||
|
||||
rpm -q binutils compat-libstdc++ gcc glibc libaio libgcc libstdc++ make sysstat unixodbc
|
||||
|
||||
The following packages (or later or earlier versions) must be installed on your system
|
||||
|
||||
- binutils-2.23.52.0.1-12.el7.x86_64
|
||||
- compat-libcap1-1.10-3.el7.x86_64
|
||||
- gcc-4.8.2-3.el7.x86_64
|
||||
- gcc-c++-4.8.2-3.el7.x86_64
|
||||
- glibc-2.17-36.el7.i686
|
||||
- glibc-2.17-36.el7.x86_64
|
||||
- glibc-devel-2.17-36.el7.i686
|
||||
- glibc-devel-2.17-36.el7.x86_64
|
||||
- ksh
|
||||
- libaio-0.3.109-9.el7.i686
|
||||
- libaio-0.3.109-9.el7.x86_64
|
||||
- libaio-devel-0.3.109-9.el7.i686
|
||||
- libaio-devel-0.3.109-9.el7.x86_64
|
||||
- libgcc-4.8.2-3.el7.i686
|
||||
- libgcc-4.8.2-3.el7.x86_64
|
||||
- libstdc++-4.8.2-3.el7.i686
|
||||
- libstdc++-4.8.2-3.el7.x86_64
|
||||
- libstdc++-devel-4.8.2-3.el7.i686
|
||||
- libstdc++-devel-4.8.2-3.el7.x86_64
|
||||
- libXi-1.7.2-1.el7.i686
|
||||
- libXi-1.7.2-1.el7.x86_64
|
||||
- libXtst-1.2.2-1.el7.i686
|
||||
- libXtst-1.2.2-1.el7.x86_64
|
||||
- make-3.82-19.el7.x86_64
|
||||
- sysstat-10.1.5-1.el7.x86_64
|
||||
|
||||
You will also need unixODBC-2.3.1 or later driver.
|
||||
|
||||
I hope you already have a user on your CentOS 7 named oracle when you installed Oracle 11g.
|
||||
|
||||
Let’s login onto CentOS by using user oracle.
|
||||
|
||||
After login to your CentOS by user oracle, open a terminal on your CentOS.
|
||||
|
||||
Now change directory and navigate to your extracted directory where you extracted both the zip files by using terminal. Now type the following in the terminal to begin installation of 12c.
|
||||
|
||||
./runInstaller
|
||||
|
||||
|
||||
|
||||
If everything goes right then you will see something like below which will start the installation process of 12c.
|
||||
|
||||
|
||||
|
||||
Then you can skip the updates or you can download the latest update. It is recommended that you must update it for production server. Though I am skipping it.
|
||||
|
||||
|
||||
|
||||
Now, select upgrade an existing database.
|
||||
|
||||
|
||||
|
||||
For language, English is already there. Click next to continue or you can add according to your need.
|
||||
|
||||
|
||||
|
||||
Now, select Enterprise Edition. You can select upon your requirements.
|
||||
|
||||
|
||||
|
||||
Then select your path for Software location. This is pretty much self-explanatory.
|
||||
|
||||
|
||||
|
||||
For step 7, keep moving with the default options just like below.
|
||||
|
||||
|
||||
|
||||
In step 9, you will get a summary report like below image.
|
||||
|
||||
|
||||
|
||||
If everything is fine, you can start your installation by clicking install on step 9 and which will take you to step 10.
|
||||
|
||||
|
||||
|
||||
In the process you might encounter some errors and you need to Goggle it for fix those errors. There are a number of errors you may encounter and hence I am not covering those here.
|
||||
|
||||
Keep your patience and it will show Succeeded one by one for step 10. If not, search it on Google and do necessary steps to fix it. Again, as there are a number of errors you may encounter and I can’t provide all the details over here.
|
||||
|
||||
Now, configure the listener just simply following on screen instruction.
|
||||
|
||||
After finishing the process for listener, it will start the Database Upgrade Assistant. Select Upgrade Oracle Database.
|
||||
|
||||
|
||||
|
||||
In step 2, you will find that it will show the 11g location path along with 12c location path. Also you will find that it is indicating Target Oracle Home Release 12 from Source Oracle Home Release 11. Click next step 2 and move to step 3.
|
||||
|
||||
|
||||
|
||||
Follow the on screen instructions and finished it.
|
||||
|
||||
In the last step, you will get a success window where you will find that the update of oracle database was successful.
|
||||
|
||||
**A word of caution**: Before upgrading to 12c for your production server, please make sure you have done it some other workstation so that you can fix all the errors, which you will encounter on the way of upgrading. Never try upgrading a production server without knowing all the details.
