The IBM AIX operating system provides a highly scalable IT infrastructure for client workloads. Learn about the latest version, AIX 7.1, an open standards-based UNIX operating system, that includes significant new capabilities for virtualization, security features, availability features, and manageability.

PowerHA for AIX is the new name for HACMP (High Availability Cluster Multiprocessing). HACMP is an application that makes system fault resilient and reduces downtime of applications. This article introduces PowerHA and provides a detailed explanation of how to configure a two node cluster. This document is very useful for understanding PowerHA and setting up a two node cluster.

Bazaar is used to produce the Ubuntu Linux distribution, which is an enormous software project with thousands of components. If you're using a UNIX or Linux system, chances are that your distribution offers a pre-built Bazaar package. Bazaar is flexible enough to accommodate Subversion - a centralized system and Git - a decentralized system. This article introduces you to Bazaar's many appealing features.

One of the most novel and differentiating features of a UNIX system is its command line. With just a few keystrokes, including a bit of "glue", you can use the command line to combine the finite set of UNIX utilities into innumerable, impromptu data transforms. These articles will teach you the basics of the UNIX shell and discover how you can use the command line:

The GNU Image Manipulation Program (GIMP) is a robust application for editing and manipulating digital images. In this article, you will learn how to get started with the GIMP code, how to build the project from the Git repositories, and how to find your way around the code tree. And you will build an example application that creates a whole new painting tool for the program.

Some UNIX protocols need investigation to understand what they are doing and what information they are exchanging. In this article, we will take a look at techniques for performing detailed analysis of the protocols in use on your UNIX network.

You don't have to break into a Watergate office to uncover the secrets of UNIX power users. There's an informant, and he's spilling the beans. Learn why Environment Variables, the dot file, and the Secure Shell (SSH)are very important.

This article describes a real-word software port, with examples of how various porting challenges are resolved. If you are a software developer porting software to UNIX, you will find these techniques invaluable in avoiding common pitfalls, resolving bugs, and improving your productivity.

Use gnuplot to dynamically generate Web pages from your system using raw data to provide graphic images. This raw data typically contains MIS-related information, on system performance, storage, or database growth.

Most AIX administrators understand the virtualization features available to them on their System p platform through PowerVM, which is also available on the System p for Linux. What about the other UNIX hardware platforms? find out what HP-UX, Solaris have to offer and how do some of their features compare to PowerVM.

Master the rich features of the Emacs editor. It's unlike any other program you're likely to have encountered. Delve into the depths of its most advanced editing commands that have made it famous.

The systems world will shortly be celebrating a major anniversary milestone. UNIX is turning 40 years old! Most of us know the story of how UNIX was born, but what about why? Was it born strictly because its founders wanted to play a computer game on a different platform? And why does UNIX continue to thrive 15 years after an (in)famous Byte Magazine article that asked: Is UNIX dead?

Are you broadening your skills as a Linux systems administrator into various flavors of UNIX? Get a rundown of the differences and similarities between Red Hat Enterprise Linux and AIX so that you can perform day-to-day activities with ease.

Pipe Viewer is one of those little-known gems that once you find it, you can't recall how you lived without it. Find oodles of uses for it in your automation scripts. You can now insert a probe to give you real-time feedback of whats happening in your pipes.

Learn about the virtualization capabilities of both HP-UX and AIX. The intent of this article is to educate you and also to help you make informed decisions as to which platform works best for you, from a feature and functionality standpoint and for your long-term strategic goals.

Keeping multiple machines synced can be challenging. Fortunately, a powerful tool is available to make the task easier: rsync, an open source utility that provides fast incremental file transfer. An important feature of rsync not found in most similar programs/protocols is that the mirroring takes place with only one transmission in each direction.

Do you know what to do when the performance of your UNIX network and the speed at which you can transfer files or connect to services suddenly comes to a stop? How do you diagnose the issues and work out where in your network the problems lie? This article looks at some quick methods for finding and identifying performance issues and the steps to start resolving them.

There's a lot more to text manipulation than cut and paste, particularly when you aren't using a GUI. This article introduces you to text manipulation on Linux using filters from the GNU textutils package. By the end of this article, you will be manipulating text like an expert.

Monitoring system logs or the status of a command that produces file or directory output are common tasks for systems administrators. Learn how to use two popular open source tools simplify these activities for modern systems administrators: the multitail and watch commands.

Active Memory Sharing (AMS) is an enhancement to IBM's PowerVM virtualization technology available on the POWER6 platform. This article describes how to configured Active Memory Sharing on AIX. It also touches on performance considerations with AMS and gives you a better understand of how AMS interacts with the virtual memory.

Look at how the leading Python testing frameworks provide robust auto-discovery of your application tests. Make sure your applications are written right the first time, and that they stay working through months and years of further tweaks and improvements.

Here's a great cheet sheet on managing NFSv4 ACLs on different filesystem with different commands. This article discusses and compares the different commands that you might use to migrate from one filesystem to another.

Learn the differences on how to work with certain tasks, such as networking and performance tuning. Also, see at a high level some of the virtualization differences among these big three. You decide what you prefer best.

Why is virtualization so important? The short answer is that virtualization enables businesses to lower their technology Total Cost of Ownership (TCO), while increasing their Return on Investment (ROI). What do the top UNIX vendors have to offer with respect to virtualization? Find out what virtualization is more scalable. Here's a look at HP's Virtual Server Environment (VSE), Sun's xVM, and IBM's PowerVM.

Much like a vernacular, the universe of UNIX tools changes almost perpetually. New tools crop up frequently, while others are eternally modernized and adapted to suit emerging best practices. To speak UNIX fluently, you have to keep up with whats New and good.
