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, chrisbensch@iname.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, marc@merlins.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, tim@vbisd.org
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, chadr@brt.com
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
