illumos and the Google Summer of Code
Experienced staff members will mentor student projects
The illumos project has been accepted as a “mentoring organization” for the Google Summer of Code program (GSoC 2012). The illumos project is a community-driven open source operating system development project derived from the former OpenSolaris project.

The GSoC program promotes open source by sponsoring summer internships for students interested in working on open source projects like illumos. Members of the illumos community (including Nexenta and Joyent) support this program by offering experienced staff members willing to mentor student projects.

If you might like to apply for one of these internships, or just want to learn more about our involvement in this program, please see the illumos GSoC page.

Transitioning Existing Oracle Solaris 10 Applications to Oracle Solaris 11
Use the Tools and Procedures Oracle Furnishes
In his post on how to transition existing Oracle Solaris 10 applications to Oracle Solaris 11 using a standard process and tools from Oracle, Stefan Schneider notes that most applications will not cause issues to be reported by the scanning tools such as Oracle Solaris Preflight Applications Checker, and they most likely will not face the issues discussed in the "Oracle Solaris 11 ISV Adoption Guide" or the Oracle Solaris 11 EOF page. While most applications will likely work out of the box on Oracle Solaris 11, some will report problems because they use outdated and deprecated frameworks and APIs.
Solaris 10 Features in Common with Solaris 11 Ease Migration
Users of Solaris 10 will Find Many Familar Features

By way of facilitating customer migrations from Oracle Solaris 10 to Solaris 11 Karoly Vegh has posted a number of features the two versions have in common. Users of Solaris 10 will find the migration less intimidating (and time consuming) when they realize the commonality that Vegh outlines, and the listed features should improve the administration experience. The post recommends Joerg Moellenkamp's PDF "Less Known Solaris Features" and provides a link to the document.

Joerg Moellenkamp's Oracle Solaris 11 Cheatsheet
Author of 'Less known Solaris Features'
Joerg Moellenkamp's Oracle Solaris 11 Cheat Sheet covers a lot of ground. Among the categories for which he provides guidance are:

  • Installation
  • System Configuration
  • Users and Groups
  • Boot Environments
  • Packaging
  • File Systems: Basic ZFS Administration
  • Service Management Facility
  • Oracle Solaris Zones
  • Networking and Manual Administration
  • Networking and Automatic and Advanced Administration

Look out for updates!

dtrace.conf 2012 in San Francisco, Tuesday, April 3rd
All Users of DTrace Are Encouraged to Sign Up
Users of DTrace for whom San Francisco is a convenient destination should reserve Tuesday, April 3, 2012, because that is the date for dtrace.conf, first held in 2008. The program is already filled with luminaries from such companies as Nexenta, Joyent, Oracle, Sony, Juniper Networks, and many others. For those unable to attend in person, the proceedings will be streamed live. The conference venue is the Children's Creativity Museum at 4th and Howard in downtown San Francisco. The entrance is behind the carousel.

Updating Oracle Unbreakable Enterprise Kernel
Installing Release 2 Without Scheduled Downtime
In his post on Oracle Unbreakable Enterprise Kernel Release 2 Lenz Grimmer describes two methods for updating Oracle Linux systems to the latest version of the Unbreakable Enterprise Kernel. With the help of Ksplice, applying future updates can even be performed without having to schedule any downtime or reboots. Switching to the latest Unbreakable Enterprise Kernel, Grimmer asserts, provides the latest innovations in mainline Linux. Switching is easy—applications and the operating system remain unchanged. There is no need to perform a full re-install; only the relevant RPM packages are replaced. The article features code samples and numerous screen shots.

Oracle Exalytics In-Memory Machine Draws Partners' Praise
Unprecedented Analytical Depths of Insight into Corporate Operations
A number of Oracle partners have high praise for the Oracle Exalytics In-Memory Machine, chiefly for the insights into corporate operations that the solution provides. The comments of David Wheeler, VP, Business Intelligence & Performance Management, Apps Associates LLC, are typical: "Our customers will now realize robust, real-time reporting coupled with proactive, forward-looking planning, modeling and predictive analysis. With Oracle Exalytics, complexity and TCO are reduced.”

Download the ZFS Storage Appliance Simulator
A No-risk Introduction to this Powerhouse Solution
If you'd like to have a idea of just how the ZFS Storage Appliance works, Steen Schmidt suggests having a look at Oracle's ZFS Storage Appliance Simulator, and he helpfully provides a link to a download of the simulator. The simulator is said to deliver the following information:

  • A graphical interface that guides your choice of replication profile

  • Oracle's Solaris DTrace analytics

  • Support for various data protocols, including CIFS, NFS, iSCSI

Users can install and manage a virtual storage system on any laptop or desktop and experience the power of NAS Storage.

    Release of LibreOffice 3.5.1 Provides Additional Security and Stability
    Developer Community Shows Remarkable Pace of Growth
    The majority of the most-important bugs identified by users have been fixed in the release of LibreOffice 3.5.1 which includes improvements in security and stability. LibreOffice 3.5.1 is available for immediate download. According to Italo Vignoli, member of The Document Foundation Board of Directors, “During the last month, the number of TDF hackers has overtaken the threshold of 400 code developers, with a large majority of independent volunteers and several companies paying full time hackers. In any case, the project is independent, as none of these companies employs more than 7% of the developers."

    How Memory Allocation Affects Performance in Multithreaded Programs
    Sniffing Out Lock Contention with Several Tools
    If your new server has an alarmingly lower transaction rate than you had anticipated, Rickey C. Weisner suggests that you look first at lock contention in the memory allocator. His article demonstrates the use of prstat to determine whether there is lock contention. Demonstrated as well is the use of Professor Emery Berger's MT-hot allocator named Hoard, and of the mtmalloc (both old and new), and the libumem memory allocators. The question of which is best is answered by Weisner's use of a test harness, which appears to give the edge to the new mtmalloc.

    Video Series Shows How to Build a JavaFX Application Using Netbeans 7.1
    Start-to-finish Instructions -- with Code Samples -- Outline Easy Path
    In her series of videos demonstrating how to build a simple JavaFX application using NetBeans 7.1 Angela Caicedo, Oracle Technology Evangelist for JavaFX, provides easy-to-follow, step-by-step instructions. The first video provides an introduction to the application and shows viewers the end result of the exercises that will be demonstrated throughout the series. The second video (Part 1) demonstrates how to get started creating the application from an empty project to build your first JavaFX application in NetBeans 7.1. The third video (Part 2) demonstrates how to handle events and binding in the sample application using JavaFX.
    Survey Results on Use of JavaFX on Mac and Linux Platforms
    Possibility Finds Favor with Clear Majority
    A recent poll on whether developers would turn to JavaFX once it is fully ported to Mac and Linux platforms is interpreted by Nicolas Lorain, Java Client Product Manager at Oracle. His finding is that some 63% are already using JavaFX in this manner or intend to while some 22% register a "maybe" or "don't know" response. Since interpolation was involved in deriving these conclusions, Lorain concedes that the only indisputable conclusion is that less than 10% of developers who have taken this poll plan to stick to another toolkit (presumably Swing or SWT).
