How Uncle Sam Gave Rise to Open Source
ArsTechnica Article Suggests Perhaps That Was the Case

Only infrequently does the history of IT occupy writers on the industry but Matthew Lasar's article "The Unix revolution -- thank you, Uncle Sam?" is an exemplary bit of IT history. Lasar backtracks to 1956 when AT&T and the U.S. Justice Department signed a consent decree that, among other things, prompted AT&T to begin licensing its formerly closely held Unix patents with the declared intention of not providing support for the code. Thus, Lasar argues, was born what we now know as "open source," though he concedes that not all will agree with his interpretation of events. In any case, the article is a rewarding read.

Oracle Solaris Security: It's a Given
Oracle Solaris: In a Class By Itself
"Oracle Solaris Security" is the topic under discussion in this episode of Oracle Solaris: In a Class by Itself. Bill Nesheim, VP of Oracle Solaris Engineering, Chris Armes, Senior Director of Oracle Solaris Engineering, and Alex Barclay, Product Manager for Oracle Solaris Security, join host Charlie Boyle. By design, the panel observes, security is part and parcel of Oracle Solaris, which has been developed within the Oracle Software Assurance process. As a result, users can protect data both at rest (e.g. with the new ZFS on-disk encryption), or in motion (e.g. with the built-in cryptographic framework). They can as well reduce insider risk with Role Based Access Control, and use Zones as a security isolation feature, capitalizing on its new delegated administration capabilities. In addition, together with process privileges, customers can add modern security policies to legacy applications without changing them, which offers enough granularity to meet their specific security requirements.
Integrated Load Balancing Feature in Solaris 11
How-to Demonstrates Balancing Traffic Across Two Zones
If you are unfamiliar with the load balancing function of Solaris 11, Brian Leonard's blog post "Integrated Load Balancer" will be helpful reading. There he provides an implementation example of the explanation from the "Integrated Load Balancer Overview" using the HALF-NAT operation mode. HALF-NAT, he explains, means that the client's IP address is not mapped so that the servers know the real client address, normally a preferred practice for server logging. In an 11-step procedure, Leonard shows how to load balance traffic across 2 zones, each running the Apache Tomcat server. The load balancer itself will be configured as a multi-homed zone.
Oracle Solaris Zones Demo on OTN
How Telco Develops and Deploys Applications Using Zones Technology
The Oracle Tech Network presents a demonstration on "Using Oracle Solaris Zones to Develop and Deploy Applications" drawn from the telco industry. The demonstration illustrates how isolation, rapid boot, built-in rollback, mobility between systems, and cloning -- capabilities built in to Solaris Zones -- enable fast and efficient application development and deployment. A link is provided to the "System Administration Guide: Oracle Solaris Zones, Oracle Solaris 10 Containers, and Resource Management" as well as to the "Resource Management and Oracle Solaris Zones Developer's Guide."

MySQL Cluster Manager 1.1.1 Available for Free Download, 30-Day Trial
Cluster Management Made Simpler and Safer

"While managing clusters will never be easy, it keeps getting a whole lot simpler," or so writes Mat Keep in his blog post "Simpler and Safer Clustering: MySQL Cluster Manager Update." He writes further that, with MySQL Cluster Manager 1.1.1 now released to General Availability it is much simpler to get up and running and to manager a cluster or even multiple clusters from a single process. MySQL Cluster Manager 1.1.1 is available free for a 30-day trial at Oracle eDelivery, Keep notes, pointing out as well the numerous upgrade operations that can easily be performed online. He draws attention to the whitepaper on MySQL Cluster Manager and to the online demo as well.

Oracle x86 Infrastructure TCO Study
Oracle's Vertical Integration Carries the Day, Edison Group White Paper Finds
The Edison Group's white paper, "Oracle x86 Infrastructure: The Optimized Stack: Reducing Total Cost of Ownership through Vertical Integration" examines the cost structures across a range of system sizes and deployments for the core x86 system stack by comparing Oracle's integrated complete infrastructure with alternatives from HP and HP, all deployed with Red Hat Enterprise Linux and VMware vSphere, both together and separately.

Among the findings is that TCO with an Oracle solution is as much as 57 percent lower than comparable deployments. Edison evaluated two, four and eight socket systems over three and five year periods using the Oracle Sun Fire X4170 M2 server for the two socket study and the Sun Fire X4470 M2 for the four socket system.

The white paper concludes that, "By engineering the entire infrastructure with service and support in mind, Oracle can deliver lower TCO in the design and operation of its system, in the ease of deployment enabled by VM Templates and Validated Configurations ... and in the efficiency and effectiveness of its ... Premier Support package."

    Live Upgrade
    Bob Netherton Offers some Survival Tips

    "Live Upgrade Survival Tips," a blog post by Bob Netherton, contains several useful suggestions that readers are well advised to employ in the process of patching software. As Netherton writes, some of his suggestions are common sense; others may surprise certain readers. Here they are:

    1. Always make sure your patching and packaging utilities are up to date

    2. Always check the logs. Always. Always. Always!

    3. Use ZFS as your root file system.

    4. Don't save patch backout files.

    5. Start using Live Upgrade immediately after installation.

    6. Remember to install the LU packages from the upgrade media.

    7. Use the installcluster script from the Solaris patch cluster.

    8. Keep it simple.

    The Oracle Hardware Management Pack
    Indispensible Tool for x86 Servers

    Oracle's Hardware Management Pack comprises two components: an SNMP monitoring agent and a family of cross platform Command Line (CLI) tools for managing and configuring Oracle Sun Fire x86 servers. The Sun Server Management Agent component provides an in-band SNMP agent for monitoring the server hardware and storage. The cross platform command line tools run on Solaris, Linux (Oracle Enterprise Linux, and current releases from Red Hat and Novell), and Microsoft Windows 2008. The tools. listed below, provide powerful and flexible configuration and update capabilities.

    • ilomconfig, configure the service processor
    • biosconfig, configure the BIOS
    • raidconfig, configure RAID components
    • fwupdate, update firmware
    • All configuration tools are Capable of loading

    The Hardware Management Pack saved the day for Peter Tribble, who blogs about his efforts to build a jumpstart profile and to map from the WWN-based device names to physical positions on the chassis of the SPARC T3-1 and the x86-based X4170 M2.

    Andy Bechtolsheim Casts His Vote for Merchant Silicon
    The Stuff that 10GB Ethernet Switches Are Made of

    Merchant silicon gets Andy Bechtolsheim's vote as the technology for Ethernet switches. He writes that throughput and cost-performance factors make merchant silicon the winner, hands down. This is reflected in the fact that, according to him, most of the 10 Gigabyte (GB) switches manufactured in the current year are based on merchant silicon. Given the network scalability demands of contemporary datacenters, Bechtolsheim writes, only 10 GB Ethernet will do as the switch. He also comments on the features of Arista's 7050-64S and compares them to those of Cisco's Catalyst 6509, asserting that the features gap between the two is closing.
