Oracle releases full virtualized Oracle Solaris 11

9 November, 2011
By Mark Cox

Oracle has announced availability of Oracle Solaris 11, the first fully virtualized OS, which it is terming the first Cloud OS. Oracle Solaris 11 is designed to meet the security, performance and scalability requirements of cloud-based deployments allowing customers to run their most demanding enterprise applications in private, hybrid, or public clouds.

Oracle Solaris 11 provides comprehensive, built-in virtualization capabilities for OS, network and storage resources. In addition to its built-in virtualization capabilities, Oracle Solaris 11 is engineered for Oracle VM server virtualization on both x86 and SPARC based systems, providing deployment flexibility and secure live migration.

“Oracle Solaris 11 is the most significant operating system release of the past decade,” said John Fowler, executive vice president, Systems, Oracle. “With built-in server, storage and now, network virtualization, Oracle Solaris 11 delivers the industry’s first cloud OS. Customers can simplify their enterprise deployments, drive up utilization of their data center assets, and run Oracle and other enterprise applications faster all within a secure, scalable cloud or traditional enterprise environment.”

Oracle Solaris Zones virtualization scales up to hundreds of zones per physical node at a 15x lower overhead than VMware and without artificial limits on memory, network, CPU and storage resources. New, integrated network virtualization allows customers to create high-performance, low-cost data center topologies within a single OS instance for ultimate flexibility, bandwidth control and observability.

Oracle Solaris 11 runs business-critical enterprise applications in virtualized massive horizontal scale as well as vertically integrated environments on a wide range of SPARC and x86 servers. Customers can run any of the more than 11,000 applications supported today on Oracle Solaris 11, with guaranteed binary compatibility through the Oracle Solaris Binary Application Guarantee Program. Customers can also preserve their existing investments by using P2V and V2V tools to move their existing Oracle Solaris 10 environments to an Oracle Solaris 10 Zone, while gaining access to the latest Oracle Solaris 11 enhancements.

“With Oracle Solaris, we have a unique opportunity to support the industry’s largest and leading business software portfolio on the industry’s best UNIX for both SPARC and x86 servers,” said Thomas Kurian, executive vice president of Oracle Product Development. “Working together, our development teams engineer, test and support advanced solutions to our customers’ toughest problems. We are pleased to announce that our key software products–Oracle Database 11g, Oracle Fusion Middleware, Oracle Enterprise Manager, and Oracle Applications–are available and optimized for Oracle Solaris 11 on SPARC and x86 systems.”

Oracle Enterprise Manager Ops Center, now included in systems support, provides converged systems management, enabling enterprise wide, centralized control over hardware, OS and virtualization resources.

Oracle Solaris 11, Oracle Enterprise Manager Ops Center and Oracle VM software are included as part of systems support with all of Oracle’s Sun servers, providing customers with built-in cloud capabilities.

Partners in Oracle Partner Network (OPN) will find new Oracle Solaris 11 tools and resources in the Oracle Solaris Knowledge Zone including the Oracle Solaris Remote Lab and the Oracle Solaris Development Initiative. New Oracle Solaris 11 Training is also available to help customers and partners take advantage of the best-in-class features of Oracle Solaris 11 and upgrade from Oracle Solaris 10 or earlier versions.

 

c0t0d0s0.org- Close

Oracle related blog closure is that of Joerg Moellenkamp who has closed his Solaris oriented c0t0d0s0.org blog, which was home to the “Lesser Known Solaris Features” (LKSF) tutorial. Moellenkamp, an Oracle employee, says the offlining of the blog is not because of health issues, that there were no technical problems and no copyright issues, but beyond that he will not say why he has taken the decision. The LKSF tutorial has been saved from the shutdown and is available to downloadPDF. The closure of the c0t0d0s0 blog does though reduce the already meagre number of Solaris blogs further.

It is worth noting that Oracle, as a company, has never been comfortable with employee blogging. Oracle appears to regard blogs as mostly a function of its public relations department and it is said that the complexity of working with the PR department to approve postings is sufficient that many either give up or don’t try.

There are rumours that Google may lauch +1 as plus.me which google recently purchased. Google is trying very hard to catch up the Facebook popularity in social realm but it failed with Buzz, so let us wait and watch how this new social connectivity will be taking up spaces..

New Persona from Firefox >>>

Personas are easy-to-use themes that let you personalize the look of your Firefox

Firefox 3.6 has introduced a new feature (that was in Beta for some time): Personas.

What’s a Persona? From Firefox’ own description: Personas are easy-to-use themes that let you personalize the look of your Firefox There’s a very nicely done video on the Firefox Personas site to introduce the feature.

If you (or your friendly sysadmin) haven’t upgraded to Firefox 3.6 yet, you can still install the Personas Plus Add-On to enjoy all of the Personas goodness.

Very easy to use indeed: Roll your mouse over a Persona image and see immediately how it looks on your browser. Click on “install” and make it permanent. Theming made super-easy!

Of course, I started searching for an OpenSolaris Persona as soon as I found out about this feature. There wasn’t any. Yet.

Creating your own Firefox Persona is really easy, so I got my hands dirty with Gimp on my OpenSolaris work machine, perused some of the supplied OpenSolaris GNOME desktop backgrounds, and…

Voila! Today, the nice and restless Firefox Personas folks approved my own homebrew OpenSolaris Persona! It’s available from the Firefox Personas website, ready to try and wear instantly!

Constantins OpenSolaris Persona

(Note: I would have loved to bring you the instant tryout and install goodness to this image, but, alas, my JavaScript, jQuery and Drupal skills aren’t sufficient to do this right now. Just click on the image to be taken to the Persona site and try it out from there.)

So, if you’re a fan of OpenSolaris, why not dress up your Firefox web browser and wear the OpenSolaris persona?

If you’re involved in any official OpenSolaris marketing: Let me know when there’s an officially approved OpenSolaris Firefox Persona, and I’ll be happy to point people at it.

Meanwhile, have fun while wearing the unofficial OpenSolaris Firefox Persona now!
