Radiant Data Corporation has released PeerFS version 3.0, peer-to-peer continuous data availability technology for Linux-based enterprise applications. PeerFS enables simultaneous transactions on multiple servers in multiple locations with separate but identical data stores. New features of PeerFS version 3.0 include support for more distributions, including Trustix and Debian, support for the 2.6 kernel and support for SuSE Standard Server 9.0 and SuSE Enterprise Server 9.0; a lost node policy that detects when one or more nodes in the configuration group is no longer reachable; and support for consistency groups with more than two nodes. In addition, PeerFS diskless clients receive new functionality with the addition of load balancing and host affinity options to the mount command.

1-Box for Linux 1.0 is standalone software that can be added on to Linux distributions in order to turn a single PC into a network of up to ten workstations. With the addition of extra dual-head video cards to the main PC, each workstation needs only a standard monitor, a USB keyboard and a mouse. Users simultaneously can browse the Internet, send e-mail and independently run any installed software they desire. 1-Box offers support for Novell, Mandrake, Fedora Core and Red Hat distributions, with support coming soon for Sun Java Desktop.

WebScan for Linux combines antivirus and content security features in order to protect the network on the gateway or proxy server level. WebScan was designed to allow organizations to control the type of Web traffic content that can flow through the gateway and to protect the network from viruses that gain access through proxy servers. WebScan can scan Web pages for content policy violations, viruses, worms, Trojans and other malware. It also allows blacklisting of MIME file types, such as audio and video, so that Internet bandwidth is used effectively. Also, HTTP file uploads can be blocked to prevent theft or leakage of sensitive data. Unauthorized access to certain Web sites also can be prevented based on ratings by organizations such as RASCi, Safe Surf and ICRA. For administration, WebScan offers an extensive reporting system for policy violations and a Web-based GUI front end for easy configuration and administration.

The PostgreSQL Global Development group has released version 8.0 of PostgreSQL, an object-relational database management system. Key new features for version 8.0 include savepoints, an SQL-standard feature that allows specific parts of a database transaction to be rolled back without aborting the entire operation. Also new for PostgreSQL 8.0 is point-in-time recovery, a feature that allows full data restoration from the automatic and continuously archived transaction logs, which is an alternative to hourly or daily backups. Version 8.0 also offers tablespaces, which allow the placement of large tables and indexes on their own individual disks or arrays, improving query performance. Finally, PostgreSQL offers improved disk and memory usage through the use of the Adaptive Replacement Cache algorithm, the new background writer and the new vacuum delay feature.

IBM announced the release of the eServer OpenPower 710, a POWER5 processor-based server running Linux. The OpenPower 710 is a one- or two-way rackmount system that uses IBM's 64-bit Power architecture and offers optional mainframe-inspired virtualization and micro-partitioning capabilities unique to POWER5 systems. The OpenPower 710 is available with 1.65GHz POWER5 microprocessors and a maximum memory of 32GB. It supports Novell SUSE LINUX Enterprise Server 9 and Red Hat Enterprise Linux AS 3. The 710 also comes with 1GB of memory, a 73GB 10KRPM disk drive, DVD-ROM and a three-year, next-business-day warranty. Four standard hot-swappable Ultra320 SCSI drive bays are available for more than 570GB of internal storage. The system has three PCI-X slots, dual 10/100/1000 Mbps Ethernet ports, hot-plug power supplies with optional redundancy and redundant hot-plug cooling.

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
