Red Hat Enterprise Linux gets cozy with MongoDB

Easing the path for organizations to launch big data-styled services, Red Hat has coupled the 10gen MongoDB data store to its new identity management package for the Red Hat Enterprise Linux (RHEL) distribution.

“The beauty of Identity Management is that it has a central infrastructure that companies can use to manage identities across many different types of applications,” said Kelly Stirman, 10gen director of product marketing. With MongoDB linked to Identity Management, those shops already using RHEL will find it much easier to set up and run applications that run on MongoDB data.

Although it already has been fairly easy to set up a copy of MongoDB on RHEL — by using Red Hat’s package installation tools — the new integration minimizes a lot of work of initializing new user and administrator accounts in the data store software.

Being connected to Red Hat Identity Management, MongoDB can use the user IDs and group permissions that are already managed within Identity Management, helping the organization to establish a SSO (single sign on) infrastructure for its employees and contractors.

Learning System Administration: What to focus on?

By ScottLew

In the fall I am taking courses in System Admin and Networking Admin, along with Cisco classes. Sometime next year I hope to get Red Hat and CCNA certifications, then try to get some experience and a job.

I am wondering what I can focus on in the meantime (and in my spare time) that will contribute to my knowledge of systems administration.

I have some experience with C++, PHP and MySql programming but they’re not really related to SysAdmin.

I was thinking learning Perl would be more helpful. Or if I could do some type of project. I’d appreciate any other ideas though. I would like to focus on something that I can put to use and/or gain experience in SysAdmin.

Any ideas would be appreciated.

vnc viewer presents black screen along with GNOME settings daemon errors.

By Miguel E. Perez

File Type: txt
Hello folks,

I’m remotely connecting through VNC to two machines, each running Red Hat 5.9, from mine which is running Windows 7. Both connections were working well before. However, now one of the machines only gives me a black screen, with a pop up that says:

“There was an error starting GNOME Settings Daemon. Some things, such as themes, sounds, or background settings may not work correctly. The last error message was: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.”

I’ve searched all over the net for a solution to no avail. One thing I tried was deleting the following files in hopes of resetting my gnome environment but this did not help either.

Files: /tmp/orbit-, .gconf, .gconfd, .gnome, .gnome2 and .metacity.

I have attached the two vncviewer log files, one from the connection that still works well and the other from the one that gives me the above errors, named bad and good respectively.

I’m new to the forum so I apologize if this is not the most adequate forum section for my problem or if I omitted any relevant files or debug information. I would greatly appreciate any help you can send my way.

What to expect after RHCE certification?

By freebird8z

I finished my RHCE certification about 2 weeks back and was wondering when will I get my RHCE certification kit and when can I create a login on Redhat website (as I heard that there is special access to some content which is only available after RHCE cert).

I also heard that we can buy some accessories (like t-shirts etc) from Red Hat store but I did not get any such alert / email 🙂

PS:: Sorry, this is not a technical question but since it is related to Unix/Linux vendor indirectly, thats why posting here.

Red Hat, Hortonworks prep OpenStack for Hadoop

Merging the worlds of big data and cloud computing, Red Hat, Hortonworks and Hadoop integrator Mirantis are jointly building a software program, called Savanna, that will make it easier to deploy Apache Hadoop on an OpenStack cloud service.

The software will “allow Hadoop to take advantage of the scale-out storage architecture that OpenStack offers,” said Adrian Ionel Mirantis CEO. “Enterprises will have a much easier way to deploy and use Hadoop at scale.”

Mirantis launched the project earlier this month, donating the code to the OpenStack Foundation. OpenStack is a collection of open source software designed to offer shared compute, storage and networking services on an on-demand basis. And Apache Hadoop is a data processing framework for analyzing large amounts of data across multiple servers in a cluster. Both sets of software are increasingly being tested and deployed by organizations.

“The cloud provides an economic low-cost infrastructure that scales out easily. And that is something that is very important in the Hadoop world, as many of these projects are spinning up quickly inside of business units, and they don’t necessarily talk with the IT folks,” said Shaun Connolly, Hortonworks vice president of strategy. Savanna will work with any standard Hadoop distribution, not just Hortonworks’ own distribution.

Red Hat releases community OpenStack distribution

Red Hat has launched a community version of its still-in-development OpenStack distribution, and it also released a preview of the enterprise edition of this distribution for those who sign up for an early adopter program.

In much the same way the community driven Fedora Linux tests many of the software programs and utilities that make their way into Red Hat Enterprise Linux (RHEL), so too will this new OpenStack distribution, which Red Hat calls RDO, serve as a proving ground for technologies that may be included in Red Hat‘s enterprise OpenStack distribution.

And like with Fedora, Red Hat is hoping to build a community of developers and users around RDO. The company announced the new community edition at the OpenStack Spring Conference, being held in Portland this week. OpenStack is a collection of open source software designed to offer compute, storage and networking services on an on-demand basis, often called IaaS (infrastructure as a service).

RDO runs on RHEL, Fedora, and other distributions based on RHEL. It includes the core OpenStack components, namely Nova, Glance, Keystone, Cinder, Quantum, Swift, and Horizon. It also comes with a number of new tools still in development, such the Heat cloud application orchestration application, and the Ceilometer resource monitoring and metering utility. Red Hat also created a new installation tool for RDO, called PackStack.

My Linux Foundation Collaboration Summit Picks and Details on Live Video Access to Keynotes

By amcpherson

For The Linux Foundation, April is not the cruelest month: it’s one of the busiest. Every year, we hold our Collaboration Summit in mid-April to bring together our members, Linux and open source community developers, open source legal minds, and large scale Linux and open source users in an intimate setting. Even as The Linux Foundation has expanded its event lineup to include LinuxCon, CloudOpen, Automotive Linux Summits, and more throughout the world, this remains our original event, and because of that, as well as it’s small size and unique format, it’s special to many of us in the community.

As we prepare I wanted to share some of my top picks for speakers and sessions, as well as remind everyone who can’t join us this year that you can watch the day 1 keynotes for free via live video stream. Just sign up on the Events website.

My picks include:

* Automotive crowd sourcing, presented by Jaguar Land Rover‘s Matt Jones. Not only will Matt be speaking about how we can open up the software design process for in-vehicle infotainment, but there will also be a Jaguar Land Rover on display at the event that includes a Linux-based infotainment system.

* Adapteva CEO Andreas Olofsson will talk about how Kickstarter helped them create the $99 supercomputer, the Parallela Project, and how that works is transitioning parallel computing through open hardware. You can get more of a sense for Andreas and his perspectives in this recap of his recent LiveLinuxQA on Twitter.

* Collaborative Projects panel. This panel will include community leadership from a variety of the Collaborative Projects we host here at The Linux Foundation. Projects represented on the panel include Yocto Project, OpenMAMA and a special guest to be announced onsite.

* Netflix’ Adrian Cockcroft, director of architecture and cloud systems, will share how the company is using Linux and managing cloud services for one of the most highly-consumed services today. He will also detail Netflix’ cloud platform. Should be interesting.

* Jon Corbet will present the latest Linux Weather Forecast. This is a “don’t miss.” Jon’s presentations are always entertaining and thorough. If you want to know what’s taking shaping in the Linux kernel, this is the keynote to attend.

I’d also encourage people to drop into a variety of the sessions on days 2 and 3. I’m especially looking forward to GNOME’s Karen Sandler on bringing more women to free and open source software; Creative Commons’ Mike Linkvayer on “Software Eats the World;” and Red Hat‘s session on persistent memory for Linux for new storage technologies and interfaces.

You can view the complete Collaboration Summit schedule to see what else you might want to check out next week online or onsite.

Lastly, we’ll be hosting a Xen Project birthday party Monday night at the Julia Morgan Ballroom from 6 p.m. –

Red Hat JBoss Data Grid now spans data centers

Red Hat has revised its JBoss Data Grid software package, which now offers the ability to replicate copies of data across different data centers, and also comes with a number of other new features that can limit downtime.

Red Hat hopes that the updates will further entice enterprises to consider using a distributed in-memory data store.

“Most customers are facing challenges in providing access to real-time information, handling huge data transaction volumes, and meeting high uptime expectations. They are unable to solve these problems by scaling a rigid, complex and very expensive traditional data tier,” said Christina Wong, who is the Red Hat product marketing manager for the JBoss Data Grid, in an email interview. “So, there is a demand for flexible, high-performance [systems] that can reduce the overhead of interaction with the data tier.”

Red Hat bills JBoss Data Grid as a distributed in-memory data store, one that can be spread out across multiple servers for improved reliability and responsiveness. Maintaining a collection of data in working memory can help enterprise applications run more quickly, because they don’t have to store or draw data from disk-based database systems. Distributing multiple copies of the data across different locations could also make the application more reliable.

What Google Gets Wrong About Patent Assertion Entities

By Tim Worstall, Contributor Google, BlackBerry, Earthlink and Red Hat have made a submission concerning the activities of “Patent Assertion Entities” or PAEs and I’m afraid that there’s a logical mistake in said submission. That mistake being that hiving off patents into a PAE is not necessarily a bad thing: indeed, standard classical economics would suggest that it’s not only a logical thing to do, it’s desirable. Google, along with BlackBerry, EarthLink and Red Hat, today appealed to the Federal Trade Commission and Department of Justice to take stronger action against companies like Lodsys, Intellectual Ventures, and other “patent assertion entities” (aka patent trolls or so-called patent privateers) — companies they believe abuse patents for financial gain and are an increasing detriment to the technology industry, costing U.S. companies alone nearly $30 billion in 2011, “and $80 billion when accounting for all costs – direct and indirect.” The submission in full can be read here. …read more

Red Hat Achieves World-record Java Benchmark Result with OpenJDK

Demonstrates Leadership with Comprehensive Open Source Solution for Enterprise-critical Java Operations

RALEIGH, N.C.–(BUSINESS WIRE)– Red Hat, Inc. (NYS: RHT) , the world’s leading provider of open source solutions, today announced that OpenJDK (Open Java Development Kit) 7, running on Red Hat Enterprise Linux 6 posted a record result on the SPECjbb2013 benchmark.(1) Application performance remains an important attribute for many customers, and this recent result validates the leading performance that is now available from an open source implementation of the Java programming language.

The benchmark is an industry-standard measurement of Java-based application performance developed by the Standard Performance Evaluation Corporation (SPEC). With this result, OpenJDK 7 demonstrates its leadership in critical Java operations per second (JOPS), the ground-breaking new metric for measuring response time on the SPECjbb2013-Composite category of the benchmark. OpenJDK 7 on Red Hat Enterprise Linux supported 60 percent [double check the math to confirm that 60 percent is accurate] more critical JOPS than the closest competitor running Oracle JDK 7 on Oracle Solaris.(2) The result validates OpenJDK’s ability to deliver world-class performance, and marks the first open source entry into this server-side Java benchmark.

Red Hat is currently a member of the OpenJDK board of directors and has long been a leading contributor to the OpenJDK community, as well as being an active supporter of Java-based application performance measurement tools. Red Hat also participated in the development of the SPECjbb2013 benchmark, a completely redesigned Java server benchmark that replaces SPECjbb2005. The new benchmark has been developed from the ground up to measure performance based on the latest Java application features, and is expected to be widely used by many interested in Java server performance, including JVM vendors, hardware developers and Java application developers.

“Achieving a superior benchmark result demonstrates the powerful performance capabilities of OpenJDK and highlights Red Hat‘s commitment to driving the future of Java,” said Jim Totton, vice president and general manager, Platform, Red Hat. “We are focused on extending our enterprise platform leadership into Java and providing our customers with an open source solution that features better overall performance and maximum throughput for critical applications.”

SPEC and the benchmark name SPECjbb are registered trademarks of Standard Performance Evaluation Corporation (SPEC). Results as of 4/3/2013, see http://www.spec.org for more information.

Solaris for a Red Hat admin

By abohmeed

Hello Solaris gurus
Recently I was assigned to work on the company’s Oracle Solaris 10 servers. Actually this is the first time I lay eyes on a Solaris machine… like ever! I’ve spent my career dealing with Red Hat run servers (I am an RHCE). I’ve also worked for a while on IBM AIX.
The question is, simply, where to start? I’ve already downloaded the entire Solaris 10 information library from Oracle. It’s huge reading resource (> 1GB) that is going to take some time to go through. So is there another source of information not for newbies but for a Linux guy like me?
To narrow things down a little my manager has asked me to handle the performance degradation problem on those servers as a first priority, so what exactly should I be looking at? I already checked the CPU, memory and disk IO but they all look normal. So any more ideas?
Thanks a lot in advance

The Government of the Canary Islands Migrates Telecommunications and New Technologies Platform to Red Hat Enterprise Virtualization

Organization Achieves a Stable, Cost-Effective, Modern and Scalable Virtualized Platform After a Migration from VMware to Red Hat Enterprise Virtualization

RALEIGH, N.C.–(BUSINESS WIRE)– Red Hat, Inc. (NYS: RHT) , the world’s leading provider of open source solutions, today announced that the Government of the Canary Islands has migrated its virtualized systems from VMware to Red Hat Enterprise Virtualization to meet the growing demands of its IT department. The new infrastructure, based on Red Hat Enterprise Virtualization, JBoss Enterprise Middleware and Red Hat Enterprise Linux, is designed to provide support for the telecommunications, information technology and computer communications infrastructure of the government. The migration improved the consolidation ratios of virtual machines per host and resulted in budget savings of up to 70 percent compared to the costs associated with the previous VMware virtualization platform.

As the Government of the Canary Islands‘ previous virtualization infrastructure could not keep up with the organization’s growing workloads, it set two objectives when it came to upgrading it. The first was to promote convergence between horizontal and vertical growth so the government could take its physical machines up to their maximum capacity and thereby reduce the number of hosts, increasing efficiency. The second was to adopt a virtualization solution that could respond to its requirements, reducing cost of ownership as much as possible and minimizing risks in terms of quality of service and future continuity.

Having evaluated its options, the public body found that Red Hat Enterprise Virtualization was more cost-effective and provided greater capacity and improved service levels and continuity. The proposal put forward by Red Hat provided cost savings of up to 70 percent compared with proprietary solutions, while enabling the IT department to adopt a modernization plan, well-suited to the requirements of the Government of the Canary Islands.

Preparing for the future, the government wanted to avoid being tied to providers with unpredictable costs, or to technologies that might not develop or even disappear over time. In these respects, the technological roadmap provided by Red Hat, the capacity that its clients have for influencing that roadmap in a collaborative fashion, the model of annual subscriptions with predictable costs, the fact that it is based on public, open source technology and the soundness of Red Hat as a company were all decisive factors in the choice made by the Government of the Canary …read more

3 of This Week's Biggest Surprises

Say what you want about the tech sector, but it’s never boring. Any given week will keep tech investors flooded with product announcements, earnings surprises, and crazy strategy shifts that absolutely nobody saw coming.

These are three of the most shocking pieces of tech news this week.

What’s going on here?
Image source: Kk5hy at Dreamstime Stock Photos.

1 . Common sense prevails
Red Hat was a busy bee near the end of the week. First it published fourth-quarter results that left investors scratching their heads overnight, and then the company helped a friend in need.

Cloud-computing expert Rackspace Hosting was sued on charges of patent infringement last year. Licensing outfit Uniloc claimed that Rackspace’s virtual machines trampled all over its description of how to do math on floating-point numbers more efficiently. Some of the machines involved run Red Hat Linux, and Red Hat stepped in to defend its customer. The company has after all agreed to indemnify its paying customers against intellectual-property claims.

On Thursday morning, Judge Leonard Davis of the Eastern District Court in Texas found Red Hat‘s arguments persuasive and sent Uniloc home empty-handed. Judge Davis noted that Uniloc was trying to patent a mathematical formula, making Claim No. 1 “unpatentable even if it is an improvement” over existing methods, and nothing in the other claims could overcome this fatal flaw.

I would agree with Judge Davis that such patents are dangerous mistakes by the Patent Office. They “would cover vast end uses, impeding the onward march of science,” he wrote.

Red Hat and Rackspace get to continue processing complicated numbers with the rounding step taking place before or after any mathematical operations

In a perfect world, this news wouldn’t belong in a rundown of major shocks. In this world, however, such a swift and decisive smackdown of patently offensive legal tactics is pretty rare. That’s particularly true in the Eastern District of Texas, where patent wranglers swarm to a generous helping of plaintiff-friendly judges and juries.

A golf clap is in order for the esteemed judge. Eastern Texas may not be a favorite venue for patent plaintiffs much linger.

2. Facebook in your pocket?
Remember the last time Facebook decided to make a phone? Me, neither. The 2011 handset sold like frozen molasses and was canceled just weeks after its introduction. Here’s a picture to remind you what you missed:

The HTC Status/ChaCha in all its glory, rim-hugging rubber case and all. Note the blue Facebook button near the bottom edge of this BlackBerry-like Android phone. Image from HTC.com.

Well, Facebook seems ready to try again. The company announced a get-together for April 4, where another Android-based product or service will see the light of day.

Nobody knows exactly what Facebook will present on Thursday, but it seems reasonable to guess at a custom Android version or even an entire hardware-and-software package with Essence of Facebook drizzled …read more
