I would like to know if it is possible to install a Red Hat 5.1 or 5.2 system from a parallel port Zip drive. —Chris Bensch, email@example.com
Yes, it should work. The distribution won't autodetect your Zip drive (I'm fairly certain), but you can tell it you have a SCSI controller and select the ppa controller, which really is SCSI, over your parallel port. You should then be able to do your install. However, Red Hat will not fit on a Zip drive. You will have to get rid of many of the packages in the /RPMS directory, and the installer will complain about not finding those packages, but should proceed with the install anyway. If you carefully choose which packages to install on the Zip drive, you may end up with a working system. In other words, it's much easier to use a Jaz drive or some other device that can hold at least half a gigabyte. —Marc Merlin, firstname.lastname@example.org
I am trying to install the Oracle8 database and don't know how to create mount points. On the installation guide, it says I need to make one software mount point /u01 and three DB mount points /u02, /u03 and /u04. Please tell me how to create them and what the difference is between these mount points. —Tim Wu, email@example.com
A mount point is just a directory. On a UNIX platform, file systems are not referred to with drive letters. They are mounted, at which time they become part of the root file system mounted on /. It is at this location that you create /u01, /u02, /u03 and /u04. You may need to check the permissions required for those directories. Also, Oracle may require you to create partitions to actually mount, but that is another issue. —Chad Robinson, firstname.lastname@example.org
Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
