Designing a Multi-Layered Security Strategy
By Glenn Brunette, Senior Director, Cybersecurity, Oracle Public Sector, Oracle

Security is a concern of every IT manager and it is clear that perimeter defense, trying to keep hackers out of your network, is not enough. At some point someone with bad intentions will penetrate your network and to prevent significant damage it is necessary to make sure there are multiple layers of defense. Hear about Oracle’s defense in depth for data centers including some new and unique security features built into the new SPARC M7 processor.

Help Us Find OTN's New Systems Community Manager!

After 5 years of managing BigAdmin (under the watchful eye of Robert Weeks) and almost as much time managing the Systems Communities of OTN, I'm getting back with my ex. No, not her. I'm not that crazy. I'm returning to writing. A coupla novels, a little technical writing, maybe a blog or two.

I asked for a parade in honor of my departure, but my boss's response was unequivocal:

"Um. No."
Parade or no parade, this means you get a chance to select the new head honcho (or honchess) of OTN's Systems Communities. There are several of them, and they will eventually encompass these topics and technologies:

  • Application Development in C, C++, and Fortran
  • Systems Management Tools
  • Oracle Solaris
  • Linux
  • Virtualization
  • OpenStack
  • Systems Configuration Support
  • Engineered Systems
  • Optimized Solutions
  • Servers
  • Storage
  • Networking

If you know someone who is comfortable with these technologies, loves to hang out with system admins and developers, and is comfortable writing about, interviewing technical experts about, and generally horsing around with these technologies and the technical trends surrounding them, point them to:

Most Excellent Job Posting for Manager of Systems Communities

Our system admins and developers in the community, and our Oracle technical experts, are a fun and fascinating bunch of people. The best part of the job is rubbing elbows with them. Give the job a try. Or tell a friend about it. If you do nothing, you might end up with someone who doesn't know how to use grep.

Tech Article: How to Start Using Docker on Oracle Linux

As Ginny Henningsen puts it, "Docker is an open source virtualization technology that creates lightweight Linux application containers." What I think is particularly cool about Docker is the portability it derives from its open-source genes. As Ginny explains:

"Docker containers can define an application and its dependencies using a small text file (a Dockerfile) that can be moved to different Linux releases and quickly rebuilt, simplifying application portability. In this way, "Dockerized" applications are easily migrated to different Linux servers where they can execute on bare metal, in a virtual machine, or on Linux instances in the cloud."

Here's her article, plus a few additional resources to help you include Docker in your Linux deployments:

Tech Article: Getting Started with Docker on Oracle Linux

by Ginny Henningsen

How to customize a Docker container image and use it to instantiate application instances across different Linux servers. This article describes how to create a Dockerfile, how to allocate runtime resources to containers, and how to establish a communication channel between two containers (for example, between web server and database containers).

A Brief Chat with the Linux Foundation

I recently got to chat with Jim Zemlin, Executive Director of the Linux Foundation. In case you were just rescued from a buried time capsule as part of a fraternity pledge, you probably already know that the Linux Foundation is a non-profit trade association that fosters the growth of Linux. It supports the Linux kernel development community, provides services to help companies adopt Linux, and hosts collaborative projects to solve problems in an increasing range of fields. It is supported by leading Linux and open source companies, including IBM, Intel, and Oracle.

More about the Linux Foundation

Every year the Linux Foundation surveys large-scale enterprises to find out how they are using, and planning to continue using, Linux. Jim was kind enough to take a few minutes to walk me through the results of this year's survey. You can listen to our conversation here:

Podcast: How Large Enterprises are Using Linux - mp3

Here's Jim's blog, his Twitter handle, and a recent Ted talk discovered by Dan Lynch.

Migration and Provisioning Strategies, Plus SWiS for Developers

OTN's next Virtual Technology Summit (VTS) is being held on these dates:

Here's some information about the sessions:

Overview

The main benefits of deploying Oracle Linux are its optimizations for the Oracle stack and the newer capabilities such as Docker that you can access long before they are released in the major Red Hat distributions. Did you know, however, that you can also optimize your applications to run better on the Oracle stack using Oracle Solaris Studio? In spite of the name, it is designed to help your Oracle Linux applications take advantage of performance, security, and reliability advances across the entire Oracle stack, particularly Oracle Database. Our first two sessions for VTS4 will show you how to migrate from Red Hat Linux to Oracle Linux and give you an overview of the capabilities of the Oracle Solaris Studio IDE. And just in case you'd like to practice a little, our third session will show you some advanced techniques for deploying applications through Oracle Virtual Box.

Session 1 - How to Migrate from RHEL to Oracle Linux

by Erik Benner

Oracle Linux has been around since 2006, and for years it has offered several advantages over the Red hat distribution which it tracks. These advantages include lower support costs, improved performance in many key areas, like SSD I/O, the ability to use Ksplice for zero downtime patching and support for emerging technologies like Docker and Openstack. Migrating your existing RHEL servers to Oracle Linux is not as challenging as many admins would expect. This VTS session will show admins how to migrate an existing RHEL 6.x system to Oracle Linux. A process that takes minutes to perform! To prepare for this lab, please have an RHEL 6.x installed, with network connectivity to the internet.

Software in Silicon and What's New in Oracle Solaris Studio

by Ikroop Dilhon

Learn about Software in Silicon Application Data Integrity and how developers can use this revolutionary technology to quickly and easily increase application reliability. Also learn about what's new in Oracle Solaris Studio, including redesigned performance analysis tools, powerful memory leak protection tools, and remote development support that enables you to develop applications for Oracle systems from virtually any desktop environment.

Advanced Provisioning Techniques for VirtualBox

by Oracle ACE Seth Miller

This presentation will demonstrate advanced techniques to accelerate the provisioning of virtual machines in VirtualBox using the VirtualBox command-line tools. The first half of the presentation focuses on the VBoxManage command-line tool itself, showing how it can do everything the GUI can with much greater efficiency and speed. The second half will take those same commands and run them in PowerShell while at the same time demonstrating PowerShell's robust scripting capabilities.

The "New to Solaris Development Forum" Has Moved

The New to Solaris Development Forum brought over from Sun Microsystems is still pretty active. It used to live in the Oracle Solaris space, but we just moved it under the Application Development in C, C++, and Fortran space.

We did this for two reasons:

  1. To create a dedicated space for systems developers.
  2. To reflect the fact Oracle Solaris Studio is an IDE for Oracle Linux as well as Oracle Solaris applications.

If you haven't been on the Forums in a while, you might not know about the changes we've made to them. Quite a few, actually.

1. It's not longer called forums.oracle.com.

It's called community.oracle.com, and looks like this:

To participate, you'll need to log in and create a profile. The system will assign you a ID such as User7877777. You can be a lout and keep that ID, or you can change it to something magnificent, like TomTheMagnificent. I hope you choose to be magnificent.

2. It's Not Just Discussions Any More

We are posting technical articles, video interviews, and other content on the Community Platform. Over time, the Community Platform and the web pages for the Oracle Technology Network will merge and become one. You can see some of that happening already:

This will take time, and we'll proceed slowly. I'll post lots and lots of blogs about the changes so you can keep track. And be sure to let me know what you think. If I can address any of your concerns by providing more information or altering our design a bit, I will.

5 Steps for Installing Oracle Database 12c on Oracle Solaris 11

You can install and run Oracle Database 12c on different platforms, but if you install it on an Oracle Solaris 11 zone, you can take advantage of these capabilities:

  • Isolation - Database processes that execute in one zone have no access to database processes running in another zone. This isolation simplifies database consolidation, allowing multiple instances and versions to coexist safely on a single physical machine.
  • Independently Managed and Autonomous Environments - A non-global zone can be booted, patched, and shut down independently. A failure or reboot of one zone has no impact on other zones (unless, of course, a failure is due to a shared component). A zone reboot is faster than a full server reboot (seconds versus minutes), so a database in a rebooted zone is available more quickly.
  • Distinctive Identity - You can define virtual network interfaces for a zone, so you can give the database instance installed on that zone its own independent host name and IP address. You can also apply networking resource controls to zones, aligning network bandwidth consumption with service level targets.
  • Easy Database Instance Migration - If a database needs more CPU power, you can add CPUs to an Oracle Solaris Zone and reboot the zone. If a database needs more compute capacity than what's available in the physical server, you can migrate the zone to a larger server.
  • Hard Partitioning - Assigning a resource pool or capping CPU cores can configure Oracle Solaris Zones as hard partitions for Oracle Database licensing purposes. This can potentially lower database licensing costs.

Tech Article: 5 Steps to Installing Oracle Database 12c on Oracle Solaris 11

by Ginny Henningsen and Glynn Foster

Ginny Henningsen and Glynn Foster from the Oracle Solaris product management team wrote down the simplest instructions for installing Oracle Database 12c in an Oracle Solaris 11 non-global zone, including how to implement hard partitioning.

How to Install and Use Oracle Solaris 11.2 for x86 from an ISO in VirtualBox

I ran into Erik Benner, founder of the SPARC/Solaris SIG group for IOUG, at Rocky Mountain Oracle User Group Training Days yesterday. He has been busy. Not only is he working on some labs and demos for OTN's upcoming Virtual Technology Summits, but he's taken the time to write a three-part blog to show you how easy it is to install and play with Oracle Solaris 11.2 for x86 on VirtualBox. In his own words ... "Recently I had a DBA at an IOUG event complain that they were unable to install from the Solaris 11.2 ISO. They had seen me demo Openstack a few weeks ago, and wanted to know how to install Solaris 11.2 in a VM. So guys… here is a step by step for you."

Part 1 - How to Install Oracle Solaris 11.2 for x86 from an ISO in VirtualBox

by Erik Benner

Covers how to launch the Solaris VM, how to assign it memory, how to create a virtual drive and configure it as a dynamic allocated drive to save space, how to install the Oracle Solaris 11.2 image, and how to start it.

Part 2 - How to Patch Oracle Solaris 11.2 the Easy Way

by Erik Benner

You've probably heard by now that the new patching system in Oracle Solaris 11 lets you patch or revert back with a simple reboot. Erik walks us through a few simple uses of the beadm and pkg update commands.

Part 3 - Managing NICs, IPs, and Hostnames

by Erik Benner

How to configure the networking capabilities of your VirtualBox environment to run Oracle Database 12c so that you can experiment with its new V$KERNEL_IO_OUTLIER views and the Optimized Shared Memory method of managing database memory. Covers adding disks and configuring them into a ZFS pool, adding a NIC to the database server, and setting up IP addresses correctly. This is done differently in Oracle Solaris 11 than in previous releases, as Erik explains.

About Erik Benner

Erik Benner is an enterprise architect for Mythics Corporation, which provides training, systems integration, consulting, and managed services for the entire Oracle product line of cloud, software, support, hardware, engineered systems, and appliances.

How to Build a Software Defined Network with Oracle Solaris 11





Before software engineers got so freakin' smart, we used to pay a special type of sysadmin to fiddle with the cables and switches at the back of our racks. They were mean, they were hunch-backed, and their fingers were stained with nicotine.

Those were the good old days. Today, network administrators wash their clothes and and sit at desks. And they use something called "software defined networking." I looked it up in the Urban Dictionary, but there was no listing for it. Which is just as well because if you ask me ...

Software Defined Networking = voodoo magic






A Little Bit About Software Defined Networking

Software Defined Networking is the equivalent of doing your homework the week before it's due. I mean, who does that? Well, the Solaris engineers at Oracle do, for starters. Talk about annoying! They started this trend back in the early days of Oracle Solaris 11. Instead of visiting Rufus in the basement server room, they designed this infrastructure that makes it possible for them to put dibs on networking resources from the comfort of the local Starbucks.

In other words, instead of Rufus yanking cables out of one box and hooking them up to another, you can simply change the cable routing by keyboard, so to speak. And assign them to virtual compute nodes. And configure all kinds of aspects about each network, including Service Level Agreements, an implement of Trotskyist-Leninist Totalitarianism if there ever was one. All without waking Rufus.

Orgad Kimchi, our fearless explorer of real-world Solaris, horsed around with not only the software defined networking capabilities of Oracle Solaris 11, but its latest features, which, in his words provide "greater application agility without the added overhead of expensive network hardware." The SDN features in Oracle Solaris 11.2 now:

  • Enable application-driven, multitenant cloud virtual networking across a completely distributed set of systems
  • Allow network service-level agreements (SLAs) at the application level
  • Provide cloud-readiness, thanks to the OpenStack distribution include in Oracle Solaris 11
  • Integrate tightly with Oracle Solaris Zones.

Tech Article: How to Build a Software Defined Network Using Elastic Virtual Switches

In Oracle Solaris 11.2

Orgad starts by walking you through the steps to set up SSH authentication and the Elastic Virtual Switch controller. Then he shows you how to configure both compute nodes, the four Solaris zones, and their virtual networks. He wraps up by showing you how to test the entire configuration to make sure it's working the way you want. Orgad writes from real-world experience, so you can trust his recommendations.

Hands On Labs for C, C++, Fortran (and Java) Developers

I've always been a fan of Oracle Solaris Studio because it's the tool of choice for bad.ass developers. Java developers are ubiquitous, Database developers get more attention here at Oracle, and marketing apps generate a lot of buzz nowadays. But Fortran, C, and C++ developers bend big iron to their will. So I'm pumped that OTN's upcoming Virtual Tech Summit (VTS) will feature two 90-minute hands-on labs proctored by members of the Oracle Solaris Studio engineering team.

Lab: How to Use the Code Analyzer in Oracle Solaris Studio

moderated by Joseph Raja
Note:Instructions will be posted here before the end of January.

The Code Analyzer is a suite of tools designed to work with the Studio C/C++ compiler to identify issues in source code. The tools in this suite are

  • Previse, for compile-time checking of errors e.g. exceeding array bounds, infinite loops, etc.
  • Discover, to identify memory leak and memory corruption issues at run time, etc.
  • Uncover, to verify test coverage and identify sections of code not being tested
  • Codean, allows comparative analysis of error report across large projects
  • Code-analyzer, an intuitive GUI that allows analyzing and fixing the errors.

This lab will show you how to identify and rectify errors with these tools.

Lab: How to Use the Performance Analyzer in Oracle Solaris Studio

moderated by Eugene Loh
Note:Instructions will be posted here before the end of January.

The Performance Analyzer is a GUI and CLI tool for examining the performance of Java, C, C++, and Fortran applications and relating it back to constructs in the source code (functions, call stacks, source code lines, data structures, etc.) so that application performance can be understood and improved. The tool can examine time spent, Solaris microstates, hardware counters (cache and TLB misses, branch mispredicts,and so on), I/O operations, heap memory usage, synchronization locks, etc. Data collection is typically statistical, giving representative results with minimal invasiveness, even on highly optimized code. It is possible to profile the Solaris kernel. A timeline display shows load imbalances, synchronization, and different phases of execution.

This lab will help you become familiar with the basic operations of the Performance Analyzer.

The Importance of Hardware

Not long ago I had a brief conversation with an "expert" in the Oracle Stack. The expert had provided a comprehensive overview of Oracle technologies, from the top of the stack all the way to the database. I asked where the second part of the overview was, the part that covered virtualization, the OS, hardware, networking, storage, engineered systems, and optimized solutions. The expert shrugged and said those were "commodities."

I can tell you from experience that deep breathing and long walks do wonders for apoplexy. It's not that I don't appreciate the software. Of course I appreciate the software. Without it, what's the point of the hardware! It's just that I don't understand how people who love the software can fail to respect the hardware.

Oracle has been broadcasting for quite a while, now, the benefits you can gain from its advances in hardware, but the reaction I usually get from the unwashed masses is "yeah, well, you've invested in it, so of course you're going to hock it."


Thank goodness there is still some common sense left in the world.

In this TechTarget editorial, Rich Castagna explains, in very simple terms, that advances in software are helplessly dependent on advances in hardware. If you rub elbows with a software zealot, show them the article.

While you're at it, make sure to take a look at Oracle's latest advances in Software in Silicon, including the Software in Silicon Cloud, which allows you to test and optimize your applications on Oracle's latest hardware before you buy it. Here are three links to get you started:

Most Active Systems ACES of 2014

One of the best parts about my job is working with Oracle ACES. They are loads of fun, interesting, and know so much more about Oracle technologies than I ever will. One of the worst parts is not having the time to give them the recognition they deserve. I won't be able to remedy that anytime soon, but I'd like to use this time at the end of the year to at least shout out to the most active Systems ACES of 2014. If you were active in 2014, please let me know so I can update this blog with your activities, as well.



Newest ACE: Brian Bream


Brian Bream is the USA's first official Systems ACE. He had tremendous depth in Solaris, SPARC servers, engineered systems, and Oracle tools, and he's keenly aware of the challenges that sysadmins face today. I've interviewed him several times for OTN Garage and Oracle OpenWorld Live. I recently wrote a blog about Brian's ACE nomination, so you can read more about him there.




Ed "Hulk" Whalen

If you search the ACE repository for Edward Whalen, he is officially listed as an expert in database management and performance. Which he is, of course. But he's also got a keen interest in Oracle Linux and Oracle VM. Here are two of the books he's written on those topics:

See Ed's Amazon page here.

Ed has also been willing to conduct and participate in interviews, plus write technical articles for OTN:

I make sure to interview him when I can, and post links to his content when I can. Ed's got deep expertise, and his community contributions and reputation are growing to the point that I expect him to be accepted as an ACE director soon.


The Prolific Alexandre Borges


Alexandre knows and teaches Oracle Solaris in depth. His real-world perspective with Solaris is priceless. In his latest book, Oracle Solaris 11 Advanced Administration Cookbook he provides in-depth coverage of every important feature in the Oracle Solaris 11 operating system. Starting with how to manage the IPS repository, make a local repository, and create your own IPS package, he explains how to handle boot environments, configure and manage ZFS frameworks, implement zones, create SMF services, and review SMF operations. Also how to configure an Automated Installer, role-based access control (RBAC) and least privileges, how to configure and administer resource manager, and finally an introduction to performance tuning.

Alexandre is also a prolific author of OTN articles. For instance, he recently finished writing an entire series on ZFS. We have published seven of them so far, with more on the way:

Seth Miller is another one of those closet Systems ACES. Though he shows up in the ACE repository as a database ACE, he knows an awful lot about engineered systems and sysadmins:



Seth recently co-authored a book about Oracle Enterprise Manager with Kellyn Pot'Vin and Ray Smith, and had the good taste to focus on the command line:

Oracle Enterprise Manager 12c Command Line Interface

By the way, that's not Seth Miller, this is Seth Miller.








El Gaucho Diego Aguirre




When Diego is not selecting the best imported beers for his cooler, he's busy trying to keep older SPARC hardware and earlier versions of Oracle Solaris running in the data centers of his native Buenos Aires. It was also his idea to write this year-end wrap-up for Systems ACES. Gracias, Diego! Here are a few of his latest blogs. They're in Spanish, but Google will kinda sorta do a lame translation.






On My Radar

Becoming an Oracle ACE requires skill, expertise, and generosity. These four technologists have it, and I will be working with them over the coming year to help them achieve it.

Top 10 Systems Articles of 2014

Glynn Foster was on fire in 2014. Not only did he create several hands-on labs for OTN's Virtual Tech Summit, but he wrote three of OTN's top 10 articles for the year. Thank you Glynn, and Thank You to all the other writers who did the hard work of filling OTN with excellent Systems content. Don Bastardo finds you worthy of note.

0. How I Simplified Oracle Database 12c and 11g Installations on Oracle Linux 6

by Ginny Henningsen, updated by Michele Casey

Updated for Oracle database 12c and Oracle Linux 6. Ginny simplifies the installation of Oracle Database 11g by automatically pre-configuring Oracle Linux with the required software packages and correct kernel parameters.

1. How to Configure the Linux Out-of-Memory Killer

by Robert Chase

What the Linux out-of-memory (OOM) killer is and how to find out why it killed a particular process. Methods for configuring the OOM killer to better suit the needs of many different environments.

2. How to Create a Local Unbreakable Linux Network Mirror

by Jared Greenwald and Avi Miller

How to create a local yum repository for Oracle Linux, and configure up2date and yum to install and update packages from the repositories.

3. Taking Your First Steps with Oracle Solaris 11

by Glynn Foster

How to install Solaris 11 using the Automated Graphical Installer, one of three installation tools provided in Solaris 11. Glynn Foster and Brian Leonard show you how to install it either on VirtualBox, on bare metal as a standalone OS, or alongside another OS in a multi-boot environment on bare metal

4. How to Get Started Configuring Your Network in Oracle Solaris 11

by Andrew Walton

dladm and ipadm in Oracle Solaris 11 supersede ifconfig. Unlike ifconfig, changes made by dladm and ipadm are persistent across reboots. Andrew Walton explains these and other changes to networking in Solaris 11, and shows you how to work with them.

5. Introducing the Basics of Service Management Facility (SMF) on Oracle Solaris 11

by Glynn Foster

The Service Management Facility in Oracle Solaris 11 makes sure that essential system and application services run continuously even in the event of hardware or software failures. This article provides a few simple examples of administering services on Oracle Solaris 11.

6. Mixing C and C++ Code in the Same Program

by Stephen Clamage

This article shows how to solve common problems that arise when you mix C and C++ code, and highlights the areas where you might run into portability issues.

7. How to Update Oracle Solaris 11 Systems From Oracle Support Repositories

by Glynn Foster

You may already know that you don't have to worry about manually tracking and validating patch dependencies when you update a version of Oracle Solaris 11. This makes updates much easier. Glynn Foster demonstrates how easy it is to update the OS from a support repository, and how to make sure everything went well.

8. How to Get Started Creating Oracle Solaris Zones in Oracle Solaris 11

by Duncan Hardie

Zones are more tightly integrated with other OS features in Oracle Solaris 11 than they were in Oracle Solaris 10. As a result, you can do more with zones than you could before. Plus, it's easier. But you still need to learn the new commands and procedures. This article by Duncan Hardie is a great start: it shows you how to create a zone using the command line, how to add an application to a zone, and how to clone a zone. All in Solaris 11.

9. How to Use Oracle VM VirtualBox Templates

by Yuli Vasiliev

This article explains how to use Oracle VM VirtualBox Templates in Oracle VM VirtualBox. It is similar to the article that explains how to prepare an Oracle VM environment to use Oracle VM Templates, but it describes how to download, install, and configure the templates within Oracle VM VirtualBox, instead of on bare metal.

Three New Dev Tips for C++ Developers

How to Find Out What Resources Your Application Has Used

by Darry Gove

If you want to know how much CPU, memory, or other resources your application has used, you can pre-load a library and define a .fini method that prints out the results. You can also take advantage of the getusage call, which provides some information about CPU time and processes. But more information is available. Darryl provides examples of how to use these two components plus others that fill in the details.

How To Rapidly Identify Performance Opportunities

by Darry Gove

Profiling is critical to improving application performance. Without profiling, it is very easy to guess where the application is spending cycles, and then expend effort optimizing code that has little effect on overall performance. Oracle Solaris Studio 12.4 provides an overview screen designed to focus you on the metrics with the most promise. Darryl Gove walks you through the overview screen and explains what it indicates about your application.

Dev Tip: How to Get Finer Grained Control of Debugging Information

by Ivan Soleimanipour

The new options in Oracle Solaris Studio 12.4 provide much finer-grained control over debug information, which allows you to choose how much information is provided and reduce the amount of disk space needed for the executable. Ivan enumerates the options and provides examples of how to use them.

Brian Bream, USA's first ACE for Systems Technologies











Since the day I met Brian Bream, I've wanted him to become an Oracle ACE for Systems technologies. He has so much depth in Solaris, SPARC servers, engineered systems, what it takes to get your value out of them, that I couldn't imagine a better cornerstone to the ACE community in the US. Plus, he's very aware of the challenges that sysadmins face today:









You see, out of the 500+ ACES and ACE Directors in Oracle's program, only six specialized in Systems technologies. If you don't believe me, go to the ACE website and enter "Solaris" in the Search field. Until today, these were the only names you'd see:

As of today, you'll also see Brian Bream on that list.

Brian, who is the Chief Technology Officer for Collier IT and has certifications in over 20 industry technologies, had already received impressive awards. He had been named Instructor of the Year twice by Sun Microsystems University. And then he won that award again through Oracle University. But to the Oracle ACE program, depth of knowledge and industry recognition are not enough. They need to see contributions to the community.

That requirement presented another challenge, because Brian made his contributions to the systems admin and systems developer communities through old school communications channels. Which the Oracle ACE program does not monitor.

You try walking up to an ex-Navy, old-school Systems guy and telling him "You need to Tweet more." You'd better duck. And you'd better run. Lest you find a copy of the Sun Systems Handbook in a hard 3-ring binder lodged in your head. (If you're too young to know what a 3-ring binder looks like, see one here.)

But Brian adapted, and we had a lot of fun bringing him into Social Media. Here are three of my favorite contributions from Brian:

You fan follow Brian Bream on the newfangled social media:

Update to My Personal Crib Sheet for the ZFS Storage Appliance

In March of 2012 I posted a blog with some resources to help a sysadmin understand the ZFS Storage Appliance. A lot has changed since then, so this is an addendum to that blog. It reflects the latest information in preparation for the release of the ZS4-4.

Recent White Papers About the ZS4

  • Migrating a Database Stored on Fibre Channel (PDF White Paper)
  • Working with the RESTful Management API (PDF White Paper)
  • Deploying 10,000+ VM's on a Single ZFS Appliance (PDF White Paper)
  • Configurations

    It now comes in two variations, instead of the three highlighted in the original blog:

    • ZS3-2 - mid-range storage for the enterprise - cluster option - up to 1.5 PB raw capacity - Hybrid Storage Pools with up to 1 TB DRAM and 12.8 TB of optimized flash cache
    • ZS3-4 - For virtualized environments requiring multiple data services and heterogeneous file sharing - single or cluster - up to 3.5 PB of raw capacity and up to 3 TB DRAM and 12.8 TB of optimized flash cache

    For a high level overview, see this Data Sheet

    Posted: Lab Instructions for November Virtual Tech Summit

    Instructions for the six Systems labs that will be presented at November's Virtual Technology Summit are now available on the OTN Community Platform.

    Prepare Your Laptops Before the Event

    You need to set up your laptop with the correct VM and configure it before the event begins. If you wait until the event, you'll be too far behind and won't be able to ask questions or join in the discussions.The Oracle VM labs, in particular, require extensive prep work.

    A New Look for Docs

    The documentation teams at Oracle have been busy the past few months. In addition to updating product-specific content, all Oracle documentation teams have been working together on a revised docs.oracle.com site that should move our information into a more modern paradigm.

    The new docs.oracle.com site just went live this past weekend. The revised site is a significant change, but we think you'll like it.

    docs.oracle.com snapshot

    Note: You might need to clear your cache to see the new version of the site.

    The new site starts with 12 major product areas, each of which has a landing page that provides more direct links to content. For example, look at the Operating Systems page. The site also includes a site-wide search (which we have wanted for several years) and a product finder. These features aren't perfect; we're still tweaking the algorithms to provide better results. However, we hope that these features make the site more useful to you than in the past.

    Of course, the documentation teams continue to improve access to product-specific content also. For example, we recently updated the Solaris 11.2 and Cluster 4.2 libraries to provide better viewing on mobile devices and to improve access to localized content.

    Do these changes mean that our docs are perfect? Of course not. Web access design is an on-going process as are content updates. However, we wanted you to know about the recent changes and ask you to take a look. Please let us know what you think.

    Learn How to Use OpenStack on Oracle Solaris From the Comfort of Your ...

    You're probably heard by now that Oracle Solaris provides a complete implementation of the OpenStack platform. Here's a quick view of the integration, courtesy of Glynn Foster:

    Horizon Cloud Management Dashboard
    OpenStack Component Nova Compute Node Neutron Cloud Networking Cinder/Swift Cloud Storage Glance Image Deployment
    Solaris Component Zones and Kernel Zones Elastic Virtual Switch ZFS Filesystem Unified Archives

    Glynn has prepared two labs showing you how to get OpenStack running on Oracle Solaris. OTN is making them available virtually, with moderators to help you, in November's Virtual Technology Summit. Because they're virtual, you get to decide whether you want to try them out in the crisp mountain air of your fairytale castle in Germany, the convenience of your Manhattan mansion (who dares to be away from Wall Street for very long these days), or even the regal splendor of Windsor Castle, provided you convince the Queen to let you update her internet.

    Lab 1 - How to Deploy OpenStack in 20 Minutes

    Use Unified Archives to quickly provision an OpenStack private cloud on a single node and deploy VM instances based on Oracle Solaris Kernel Zones. The basics of cloud administration through the Horizon web interface, and how to quickly provision both Cinder block and Swift object storage using the ZFS file system. Also how the network virtualization features in Oracle Solaris 11 provide the necessary infrastructure to Neutron networking.

    Lab 2 - Deploy a Secure Enterprise Private Cloud with OpenStack

    Picks up where the first lab left off. Create a golden image environment for an Oracle Database installation using Unified Archives, upload this image to the Glance image repository in OpenStack, and deploy it using Nova compute to a VM instance. How to secure that application in a sandboxed environment using Immutable Zones, and check them for compliance using the integrated framework included in Oracle Solaris 11.

    Register Here

    The Virtual Technology Summit is a lot of fun, but you need to register. It's free. It lasts 4 hours. And it's all technology.

    We'll also have labs for Oracle Linux and Oracle VM. I'll tell you more about those in an upcoming blog.

    New Cookbook: Oracle Solaris 11 Advanced Administration

    The articles written by Oracle ACE Alexandre Borges never fail to provide real-world insight into the use of Oracle technologies, particularly Oracle Solaris. They also explain concepts with the patience and care that only professional instructors demonstrate.

    Alexandre has just written a book with the same insights and real-world practicality as his articles.

    Oracle Solaris 11 Advanced Administration Cookbook

    by Alexandre Borges

    In-depth coverage of every important feature in the Oracle Solaris 11 operating system. Starting with how to manage the IPS repository, make a local repository, and create your own IPS package. How to handle boot environments, configuring and managing ZFS frameworks, and ZFS shadowing. Implementing zones, creating SMF services, and reviewing SMF operations. How to configure an Automated Installer, which is part of the new software deployment architecture introduced in Oracle Solaris 11. Role-based access control (RBAC) and least privileges, how to configure and administer resource manager, and finally and introduction to performance tuning.

    Here is an excerpt, taken from the introduction to creating, activating, and destroying a boot environment:

    Let's imagine a scenario. We are requested to update Oracle Solaris 11, and to do this, we need to reboot the system, insert the Oracle Solaris 11 installation DVD, and during the boot, we have to choose the upgrade option. Is the upgrade complete? Is there no further problem? Unfortunately, this is not true because there are some potential tradeoffs:
    • We had to stop applications and reboot the operating system, and users had to stop work on their tasks.
    • If there was trouble upgrading the Oracle Solaris operating system, we'll lose all old installation because the upgrade process will have overwritten the previous version of Oracle Solaris; consequently, we won't be able to reboot the system and go back to the previous version.
    As you will have realized, this is a big threat to administrators because in the first case, we had a working (but outdated) system, and in the second case, we risked losing everything (and our valuable job) if anything went wrong. How can we improve this situation?

    In Oracle Solaris 11, when we are requested to upgrade a system, Oracle Solaris 11 takes a BE automatically to help us during the process. The boot environment is a kind of clone that makes it possible to save the previous installation, and if anything goes wrong during the upgrade, the boot environment of Oracle Solaris 11 lets us roll back the OS to the old state (installation). One of the biggest advantages of this procedure is that the administrator isn't obliged to execute any command to create a BE to protect and save the previous installation. Oracle Solaris 11 manages the whole process. This has two advantages: the upgrade process gets finished without rebooting the operating system, and the boot environment enables us to roll back the environment if we encounter a problem.

    Nowadays, professionals are making heavy use of the BE, and this is the true reason that creating, activating, and destroying BEs is most important when administering Oracle Solaris 11. You can be sure that this knowledge will be fundamental to your understanding of Oracle Solaris 11 Advanced Administration.

    I took the photo of some kind of flower (no clue what kind it is) on my hillside during a particularly wet summer in Colorado.

    Latest Hands-On Lab by Orgad Kimchi: How to Set Up a Hadoop 2 Cluster with Oracle Solaris

    If you're going to San Francisco, be sure to wear some flowers in your hair. Especially if it's for Oracle OpenWorld. And while you're there, don't miss Orgad Kimchi's latest hands-on lab.

    Lab: How to Set up a Hadoop 2 Cluster with Oracle Solaris

    In his own words ...

    "This hands-on lab presents exercises that demonstrate how to set up an Apache Hadoop 2 (YARN) cluster using Oracle Solaris 11 technologies such as Oracle Solaris Zones, Oracle Solaris ZFS, and Unified Archive. Key topics include the Hadoop Distributed File System (HDFS) and the Hadoop MapReduce programming model. It also covers the Hadoop installation process and the cluster building blocks: NameNode, Resource Manager, History Server, and DataNodes. In addition, you will see how you can combine the Oracle Solaris 11 technologies for better scalability and data security and will learn how to enable a HDFS high-availability cluster and run a MapReduce job."

    I'll try to convince Orgad to eventually make that lab available to those who of us who can't afford the tickets to Oracle OpenWorld.

    More Gems from Orgad

    Orgad regularly writers terrific articles that show you how to put Oracle Solaris technologies to use in the real world. Here are a few of them:

    Making Sure Your Exadata Is Running Right

    The service department of a local Harley Davidson dealer has a display that compares a chain driven cam to a gear driven cam. Each type of cam drive is attached to a cam support plate, and the service writer walks you up to the display and invites you to turn each of them. The chain drive is hard to turn, but the gear drive turns easily.

    The message is clear: replace the chain-driven cam in your Harley with a gear-driven cam, and you'll have more power. The display gets the message across brilliantly. Except that it's bogus.

    I've spun the chain drive taken out of a Harley Davidson, and it turns just as easily as the gear drive. Heck, why wouldn't it? In their zeal to convince us of the benefits of gear-driven cams, the boys at the dealership tightened down the chain drive in their display perhaps a bit too enthusiastically.

    Oracle makes some pretty big claims about its engineered systems, too. For instance, you've probably heard something along these lines for the Oracle Exadata Database Machine:

    "An engineered system with preconfigured, pretuned, and pretested hardware and software components that is designed to be the highest performing and most available platform for running Oracle Database."

    How can you know whether these claims are true? Because you have Brian Bream on your side, that's why. Brian is the Chief Technology Officer at Collier IT, and Instructor of the Year for both Oracle University and Sun Microsystems University. He knows his stuff. And he just wrote an article that will interest anyone who manages an Exadata Database Machine.

    Tech Article: Monitoring Oracle Exadata Storage Servers

    by Brian Bream

    The Oracle Exadata Database Machine gives sysadmins three monitoring technologies and two monitoring tools for its storage servers. Brian explains how they work, and how you can use them to monitor metrics, thresholds, and alerts (incidents), how to check the availability of your storage servers, and how to compare metrics for multiple storage servers.
