Using Linux in a Training Environment
As mentioned earlier, most, if not all, Linux distributions ship with a multitude of packages which would cost you extra from some commercial vendors. A third party Motif derivative for Linux runs far less than the asking price from OSF. In fact, one of the reasons that I became involved with Linux was the steep-pricing structure issued by SCO. I am a former employee of a SCO VAR, reseller and software development house. I decided that I would purchase SCO for myself and run it at home on one of my spare machines. I laid out $1,500 just for the base operating system, only to discover that to add TCP/IP and the Developer Kit another $1,500 would be in order—not for me.
This is truly the most pressing battle you may need to fight. Since there is no central technical support group for Linux, internal staff are responsible for all maintenance and support of the system. If you don't have a true Linux fanatic around or someone, who plans on becoming one in a hurry, you might be better off with a commercial solution. We have two Linux mongers on our instructor staff, with another dozen or so in our local consultant base—works out rather nicely for us.
Up until now, most commercial software developers and vendors shied away from marketing Linux native tools. However, a new trend is coming into play. Thanks to some key players in the industry (Caldera, WordPerfect, etc.), more and more tools are becoming available for Linux proper. I expect this trend to continue, as more and more Linux machines appear in the workplace. In addition to the Linux native packages which are becoming available, another option exists. Under the freely available iBCS2 emulator, binaries for other iBCS-supported platforms can be utilized under Linux. In fact, we have had great success running the SCO versions of many packages under Linux, including WordPerfect/X and Oracle 7. While a further discussion of iBCS2 is an entire series of articles in itself, it is something you may wish to explore further at least as an interim solution.
In order to assist others in putting together a Linux solution, I have put together a list of tips and pointers to give you a good starting point. Some of these areas are discussed further in the wonderful white paper by Caldera, Inc., “Using Linux in a Commercial Setting.” The primary focus of your effort is probably to convince management that a freely available OS is a viable solution. This is rarely an easy task by any stretch of the imagination. If you have strings in the company, plan on pulling them.
Before presenting your case to management, be sure to have a game plan in order. Don't jump up and shout “Let's run Linux.” at the first project meeting. Corporate ties with commercial solution providers often run deep, so be careful. Put together a detailed implementation plan, complete with a cost savings analysis and time schedule. There are a number of things you can do to help yourself in this regard.
Actively research the necessary areas. Provide solid numbers for commercial solutions. Be sure that you have accommodated all aspects of the project within your proposal. Make sure that all issues of connectivity and software facilitation have been addressed. Think of it as a legal battle—leave no loopholes in your argument.
Obtain and maintain high-level contacts in the industry. Meet with other folks who have successfully implemented a Linux solution. They may be able to provide additional insight into your argument. Planning on running the latest and greatest version of “product X” under Linux? Chances are, someone else has already driven the Linux wagon down that road—investigate.
Establish a good flow of incoming information. Actively participate in the various Linux newsgroups. They are a wonderful resource for obtaining contacts and production information. Subscribe to Linux Journal. Helpful articles and vendor information are in abundance with each issue.
Hardware integration—make sure that your proposed hardware will function once its all together on-line. If you can't do it yourself beforehand, try to find someone who has. The worst thing in the world is to win the battle with management and run into hardware issues which require additional purchases to patch a problem that you didn't foresee.
Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
