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.

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.

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.

You'll definitely want to do the prep work before the day of the event. The prep work consists of configuring your laptop and uploading the images. Don't be that guy. The one who, the day of, asks where the instructions are. Him. Don't be him.

Pre-Event Checklist

The checklist provides:

  • Virtual Conference hardware requirements
  • Virtual Conference software requirements
  • Setup instructions for Oracle Solaris labs
  • Setup instructions for Oracle Linux labs
  • Setup instructions for Oracle VM labs

If You Must Tweet

If you can't keep your hands off your danged phone while working on the labs, at least use this hashtag:

#OTNVSAD

Questions for Ed

Oracle ACE extraordinaire Ed Whalen and I will be hanging out at the Sysadmin Lounge during the last 30-45 minutes of the event. Ed knows his stuff, so if you have any questions about Linux, such as how to optimize it for the database or other applications, ask Ed. If you have questions about Harleys or Ducatis, ask me.

See you next week.

Next Virtual Sysadmin Day Is On Jan 28

OTN's next virtual sysadmin day is on January 28. It's four hours long, from 9:00 am - 1:00 pm PT. (Time converter here.) This time we have a whole new set of hands-on labs for Oracle Solaris, Oracle Linux, and Oracle VM. Proctored, of course, which means you can ask questions. The labs in our previous virtual sysadmin day focused on the basics. These focus on using these technologies in real-world scenarios. Click on the Agenda tab in the registration page to see the labs.

The event is free, but you do need to register. And there's a little homework involved. Nothing too complicated. We just expect you to have VirtualBox installed and the proper images already imported before we begin class. Click on the the Instructions tab for more info.

Register here.

Picture is of Mosquito Pass, in Colorado, taken from Mosquito Gulch. You need a 4x4 with good ground clearance to get up and over the top, and the rocks on the road will slice up your tires unless they're good and thick. A great place to catch your breath after you finish the hands-on labs.

Live Video Interviews on OTN Central at Oracle OpenWorld 2013

Good thing I drove to Oracle OpenWorld this year instead of riding the moto like I have on some previous OOW's. We had an inch of slush on Donner pass, and if we hadn't skeedaddled outta there when we did, we might have wound up like the ATV in my driveway in Colorado.

This year Oracle wants its customers to talk about their experiences with Oracle technologies, so OTN has lined up three live interviews. If you're at Oracle OpenWorld, you can watch them on the big screens. If you're not at the event, you can still watch them live from our home page at www.oracle.com. If you want to watch them later, look for a future blog in which I'll post the location of the recorded interviews.

Monday, 12:00 noon PT - John Dome, Systems Engineering Lead, Progressive Insurance

John will describe the business opportunity that lead Progressive Insurance to switch from Red Hat Linux to Oracle Linux, he'll explain why he recommended they switch, the results they got, and how it has changed the way Progressive's DBA's and SA's work together. We'll try to get as techie as we can in the time we have.

Tuesday, 11:50 am PT - Gautham Sampath, Chief Information Technologist, Pinellas County Government

Gautham (pronounced like Batman's Gotham) recently led an effort to refresh the Pinellas County hardware systems. He'll explain what they were looking for, why they chose Oracle Exalytics, how they became convinced it was the right decision, and how it changed the way they managed their data center.

Wednesday, 11:00 am PT - Brian Bream, CTO, Collier IT

Brian Bream, Chief Technology Officer of Collier IT, will describe the biggest changes data centers must deal with today, and how Collier IT recommends they face them. When we're done, he'll confess how he deals with his personal addiction to SPARC systems and the Oracle Solaris operating system.

Plus recorded videos

We're also going to have a snowsquallfull of recorded interviews, which we'll begin posting during the evenings, since going to all-night parties is getting harder and harder to recover from. Look for them on OTN Garage YouTube Channel.

Hands-On Labs + Proctors = Genius

If Albert Einstein (image removed from blog) had attended OTN's virtual sysadmin days, he wouldn't have gotten so old figuring out his Theory of Relativity. Thanks to the relentless advance of technology, you can outsmart Einstein from the comfort of your own office. See below.

OTN Virtual Sysadmin Day - July 2013

It's free - register here

We held our first ever virtual sysadmin day for North America on January 15 of this year. Almost 600 sysadmins attended and over 80% of them remained online for the duration of the event. Which means they found it a good use of their time. If you missed that one, we're doing another one in July. Oddly enough, we chose the same date and time: the 15th at 9:00 am PT. Which is at exact same spot of the Earth's rotation, but on the other side of the sun and closer to our upcoming collision with Adromeda.

That galactic fender-bender aside, we have updated some of the hands-on labs about Oracle Solaris and Oracle Linux that we presented at our in-person sysadmin days, and we added three new labs about Oracle VM:

  • Deploying Infrastructure as a Service
  • How to Virtualize and Deploy Oracle Applications Using Oracle VM Templates
  • Creating an x86 Enterprise Cloud Infrastructure

Details here.

The event is free, but you do need to register. And there's a little homework involved. Nothing too complicated. We just expect you to have VirtualBox installed and the proper images already imported before we begin class. You'll see the instructions after you register.

When was that again?

Uploaded so far:

Which Oracle Solaris 11 Technologies Have Sysadmins Been Using Most?

Director's Cut - Uncensored - Markus Flierl, VP Solaris Core Engineering, describes how Oracle Solaris 11 customers are taking advantage of the Image Packaging System and the snapshot capability of ZFS to run more frequent updates of not only the OS, but also the applications (agile development, anyone?), and how they're using the network virtualization capabilities in Oracle Solaris 11 to isolate applications and manage workloads on the cloud.

Watch How Hybrid Columnar Compression Saves Storage Space

Director's Cut - Uncensored - Art Licht shows how hyprid columnar compression (HCC) compresses data 30x without slowing down other queries that the database is performing. First he shows what happens when he runs database queries without HCC, then he shows what happens when he runs the queries with HCC.

Security Capabilities and Design in Oracle Solaris 11

Director's Cut - Uncensored - Compliance reporting. Extended policy. Immutable zones. Three of the best minds in Oracle Solaris security explain what they are, what customers are doing with them, and how they were engineered. Filmed at Oracle Open World 2012.

Why DTrace and Ksplice Have Made Oracle Linux 6 Popular with Sysadmins

Use the DTrace scripts you wrote for Oracle Solaris on Oracle Linux without modification. Wim Coekaerts, VP of Engineering for Oracle Linux, explains how this capability of DTrace, the zero downtime updates enabled by KSplice, and other performance and stability enhancements have made Oracle Linux 6 popular with sysadmins.

Why Solaris 11 Is Being Adopted Faster Than Solaris 10

Sneak Preview - Uncut Version - Lynn Rohrer, Director of Oracle Solaris Product Management explains why customers are adopting Oracle Solaris 11 at a faster rate than Oracle Solaris 10, and proves why you should never challenge a Montana woman to a test of strength.

Heading Out to Oracle Open World

In case you haven't figured it out by now, Oracle reserves an awful lot of announcements for Oracle Open World. As a result, the show is always a lot of fun for geeks. What will the Oracle Solaris team have to say? Will the Oracle Linux team have any surprises? And what about Oracle hardware?

For my part, I'll be one of the lizards at the OTN Lounge with the OTN crew, handing out t-shirts to system admins and developers, or anyone who is willing to impersonate one. I understand, not everyone can have the raw animal magnetism of a sysadmin, or the debonair sophistication of a C++ developer, so some of you have no choice but to pretend. I won't judge.

I'll also be doing video interviews of as many techie people as I can corner. I've got more than 30 interviews already scheduled. Most of them will be 3-5 minutes long. I'll be asking our best technical minds what's cool about their latest technologies and what impact it will have on system admins or system developers. I'll be posting those videos here:

Find OTN Systems Videos from Oracle Open World Here!

We've got some great topics in mind. A dummies guide to hardware-assisted cryptography with Glenn Brunette. ZFS deduplication. The momentum building around Oracle Solaris 11, with Lynn Rohrer, plus conversations with partners who have deployed Oracle Solaris 11. Migrating to Oracle Database with SQL Developer. The whole database cloud thing. Oracle VM and, of course, Oracle Linux.

So even if you can't be part of the fun, keep an eye out for the videos on our YouTube channel.

Worth the Money?

source

Learning a new technology really is the modern equivalent of doing the Ulysees thing in Homer's Odyssey. If you're the person who has to actually deploy the darned thing. And keep it running.

First, you have to wade through the marketing designed to mesmerize your boss ...

The eData Cloud-Optimized Storage Environment solution increases the adaptability of scalable business continuity while protecting infrastructure integrity optimized for the demands of reliability, availability, and security expressly designed for the unique requirements of the data center while enhanced for today's particular, unique, and demanding enterprise challenges. In a heterogenous computing environment.

So you shake your head vigorously in the hope that most of those words will fall out your ears, and go to the documentation, which is wicked, wicked useful. Once once you have a good idea of what you want to do. But frustrating as hell when you're not sure what you're supposed to be doing. Or why.

The technical articles that OTN publishes help a lot, but they don't give you the complete picture, do they? You wind up knowing how to do some really cool things, but not having a clue how to do others. Or worse: not knowing if there are other things you need to know.

So you go to the forums. And ask a question. OTN's forums are pretty good, but even in our forums you might not get an answer. And you might develop a lasting relationship with somebody born in San Quentin Prison who dedicates himself to stalking you for the rest of his life for wasting 18 seconds of his precious time.

We're all used to this, and repeat it hundreds of times throughout the year.

But wouldn't it be nice to learn something the easy way? Just once? Have somebody who really knows what they're talking about give us the complete picture? First at the high level so we get to see all the pieces and finally understand what it is we're dealing with. That alone is almost priceless. But also in full detail, so we know how to actually install, deploy, manage, and update a technology. From end to end. Because we've done it ourselves. More than once.

For me, that would be Christmas in August. The catch for most sysadmins nowadays is that there just isn't enough time to take a class. You can't get away from the office long enough without the place burning down. Which is why Oracle University came up with its on-demand format. Here's one example:

On Demand Training: Transition to Oracle Solaris 11

Like the average sysadmin, I have little to no free time during my work week. So I can't sign up for a week-long class. And even if I did, I wouldn't pay attention half the time because I'd be answering emails, IM's, and phone calls. So this on-demand format really works for me. Plus, the content is really good. An example of how the instructor sets the context for the new installation tools in Oracle Solaris 11, with just a few words:

"Now, speaking of Solaris installations, we have essentially three different ways that we can install this. We have the automated installer. Now, the automated installer is the replacement for JumpStart. The idea here is we're installing across the network. We have a manifest that lists what component should get installed. We have client profiles that say OK, these are the clients that should get the software.

"Then we have a couple of different interactive installation options. We have a LiveCD. Now, LiveCD is designed for the desktop environment. It has a GUI environment. So for those of you that are dealing with installations that are going to happen on a desktop or notebook computers, generally, you're going to do a LiveCD installation of that. Then we have the text installer. That's typically what you're probably used to in server deployments where it's a text-based interface where you're answering the questions to install the operating system so that you're not having to worry about the resources of a graphical environment."

If you're wondering why I'm blogging about this course on OTN Garage (again), it's simple: I'm taking the course right now, in between my other work, and I'm freakin' loving it! In my case, Oracle is paying for it. But after decades of trying to learn this technology on my own --with access to Oracle's engineers, mind you-- even if Oracle didn't pay for it, I'd be awfully tempted to stop buying motorcycles and pay for it myself. Just for the peace of mind. For the relief of being certain that I know what I'm talking about.

If the link above doesn't work for you, try this one.

Just because I’m paranoid doesn’t mean…

KeyholeWhile I’m a passionate computer user–recognized within my family and circle of friends as a reigning (or at least old) geek–I spend at least as much time warning people to be careful as I do showing them the cool things they can do with their computers. I’m shocked at the widespread complacency over computer and network security and privacy: we should all be afraid. Very afraid. I only need remind you of recent security breaches with LinkedIn and Dropbox!

I have been in the business of publishing systems best practices for over a decade: security has been a keystone topic all those years. The good news is that high levels of security can be achieved: you just have to be smart about it. With a few exceptions, security isn’t something we actually sell, because it is dominated by relatively unglamorous concepts, processes, and practices, not extra hardware and software.

Because of this, security experts often find themselves trying to teach really fundamental (and after-the-fact, obvious) concepts. For example, in building a secure environment, you want to make sure your platform fulfills four important points:

  • It must be able to prevent or minimize the damage caused from both accidental and malicious actions. This is referred to as survivability.
  • It provides a layered set of defenses exist so that secure operations continue even after a vulnerability or the failure of a single security control. This is referred to as defense in depth.
  • It provides only those services that are absolutely necessary to the function or user. This is referred to as least privilege.
  • It is critical to be able to detect and report a breach. This is referred to as accountability.

We just posted an important article, written by three security experts I have worked with for a long time: Best Practices for Securely Deploying the SPARC SuperCluster T4–4. In building a solution that will survive a world of sophisticated cyber-criminals, it is more important than ever to pick the correct hardware and software platform. This article gives you a crash course in the things to consider, and explanation of the special features of the SPARC SuperCluster T4–4 that will make your job of creating a secure environment easier, and (most importantly) how to go about putting things together.

This is a big and important topic. Once you have digested this “Reader’s Digest” article, I’m confident that you’ll want to look at the references listed at the end. Now is the time to get smart about security.

You might be able to on Thursday, August 23rd. OTN is hosting its next Sysadmin Day in Denver, Colorado, and we can never keep track of our sysadmins. In a place as purty as Colorado, it will be even harder.

Note: The date on the link above is incorrect. The correct date is Thursday, August 23rd.

Our previous OTN Sysadmin Day in Santa Clara had almost 100 attendees. The one in Denver will have similar presentations, but we're adding some content on virtualization. Which we hope to expand into a third track in the future. As usual, Pavel Anni opens our OTN Sysadmin Days with a talk about Oracle's dual OS strategy. He explains why Oracle offers two operating systems, and summarizes the main features of each one. Then we split off into two different groups to get our hands on each OS.

One group gets their hands on the ZFS filesystem, virtualization capabilities, and security controls of Oracle Solaris.

The other group gets their hands on the package management tools, services, and runs levels of Oracle Linux, plus its volume management tools and the Btrfs filesystem.

Both groups learn by doing, using the hands-on labs similar to those on OTN's Hands-On Labs page. Why attend an event in person when you could simply work the labs on your own? Two reasons:

  1. Since you are away from the obligations of the data center, you get to focus on working the labs without interruption.
  2. You get help from Oracle experts and other sysadmins who are working on the same labs as you.
The event is free. Here's the agenda:

Time Session
8:00 am System Shakedown
9:00 am Oracle's Dual OS Strategy
 

Oracle Solaris Track

Oracle Linux Track

10:00 am HOL: Oracle Solaris ZFS HOL: Package Management and Configuration
11:30 am HOL: Virtualization HOL: Storage Management
1:00 pm Lunch / Surfing OTN
2:00 pm HOL: Oracle Solaris Security HOL: Btrfs filesystem
3:00 pm Presentation: Oracle Enterprise Manager Ops Center 11g
3:30 pm Presentation: Oracle VM Manager
4:00 pm Discussion: What are the most pressing issues for sysadmins today?
5:00 pm Get lost in the mountains.

Viewing at Impossible Angles

Multibus driverThe picture of the little screwdriver with the Allen wrench head to the right is bound to invoke a little nostalgia for those readers who were Sun customers in the late 80s. This tool was a very popular give-away: it was essential for installing and removing Multibus (you youngsters will have to look that up on Wikipedia…) cards in our systems. Back then our mid-sized systems were gargantuan: it was routine for us to schlep around a 200 lb. desk side box and 90 lb. monitor to demo a piece of software your smart phone will run better today.

We were very close to the hardware, and the first thing a new field sales systems engineer had to learn was how put together a system. If you were lucky, a grizzled service engineer might run you through the process once, then threaten your health and existence should you ever screw it up so that he had to fix it.

Nowadays we make it much easier to learn the ins and outs of our hardware with simulations–3D animations–that take you through the process of putting together or replacing pieces of a system. Most recently, we have posted three sophisticated PDFs that take advantage of Acrobat 9 features to provide a really intelligent approach to documenting hardware installation and repair:

Download one of these documents and take a close look at it. You can view the hardware from any angle, including impossible ones. Each document has a number of procedures, that break down into steps. Click on a procedure, then a step and you will see it animated in the drawing.

Of course hardware design has generally eliminated the need for things like our old giveaway tools: components snap and lock in. Often you can replace redundant units while the system is hot, but for heaven’s sake, you’ll want to verify that you can do that before you try it!

Meanwhile, we can all look forward to a growing portfolio of these intelligent documents. We would love to hear what you think about them.

Santa Clara On April 10 - Next OTN Sysadmin Day

Before the part of Oracle that was then Sun Microsystems moved in, the facility used to be known as the Agnews Insane Asylum. Some of us who worked for Sun at the time thought the image was hilarious. Some thought it was insensitive. Some believed it was a statement about the rise of the corporate state and the demise of benign government. That was the Santa Clara campus back then, a diverse, magical workplace full of people who held strong opinions about everything, yet managed to have a great time together.

Another topic that incites strong opinions among good friends is Oracle Solaris vs Oracle Linux. Which one is better? Which one should I use? Which one should I learn how to use? At our OTN Sysadmin Days, we let you decide. Pavel Anni always opens our OTN Sysadmin Days with a talk about Oracle's dual OS strategy. He explains why Oracle offers two operating systems, and summarizes the main features of each one. Then we split off into two different groups to get our hands on each OS.

One group gets their hands on the ZFS filesystem, virtualization capabilities, and security controls of Oracle Solaris.

The other group gets their hands on the package management tools, services, and runs levels of Oracle Linux, plus its volume management tools and the Btrfs filesystem.

The truly adventurous sysadmins jump between groups. Both groups learn by doing, using the hands-on labs similar to those on OTN's Hands-On Labs page. Why attend an event in person when you could simply work the labs on your own? Two reasons:

  1. Since you are away from the obligations of the data center, you get to focus on working the labs without interruption.
  2. You get help from Oracle experts and other sysadmins who are working on the same labs as you.

I've been to all our OTN Sysadmin Days so far. The sysadmins and IT managers who attended told me that it was time very well spent. However, our attendance has been low. Not sure whether we haven't gotten the word out to enough people, or whether it's just difficult for sysadmins to get away. In any case, if we don't improve attendance, we'll have to cancel OTN Sysadmin Days.

So if you're interested, register now. Santa Clara on April 10 may be your last chance. The event is free. Here's the agenda:

Time Session
8:00 am System Shakedown
9:00 am Oracle's Dual OS Strategy

10:00 am HOL: Oracle Solaris ZFS HOL: Package Management and Configuration

Next OTN Sysadmin Day is on January 18

Our next OTN Sysadmin Day will be held on January 18 in Salt Lake City, Utah. As usual, we will have two tracks of hands-on-labs:

Time Session
8:00 am System Shakedown
9:00 am Oracle's Dual OS Strategy / Overview of OTN
 

Oracle Solaris Track

Oracle Linux Track

10:00 am HOL: ZFS HOL: managing packages, configuring services
11:30 am HOL: Exploring OS, network, and storage virtualization HOL on Storage Part I: managing storage and file systems
1:00 pm Lunch Break
2:00 pm HOL: Managing software with IPS HOL on Storage Part II: Device Mapper, BTRFS
3:00 pm Presentation: Oracle Enterprise Manager Ops Center 11g
4:00 pm Discussion: What are the most pressing issues for sysadmins today?
5:00 pm We all go home

Participants of previous OTN Sysadmin Days found the hands-on labs particularly valuable. You get to learn by doing. And what you get to do is install, configure, and manage the technologies of Oracle Solaris 11 and Oracle Linux in the same way as you would in the real world.

OTN Sysadmin Day in Salt Lake City is free, but you must register. Please stay for the feedback session at the end. They tend to be pretty spirited, and you might win a neat prize. Address:

Salt Lake City Marriott City Center
220 South State Street
Salt Lake City, UT 84111

If you'd like to see some pictures from the Sacramento event, go to the "OTN Sysadmin Day Sacramento" photo folder on the OTN Garage on Facebook.

Santa in the OTN Garage

You are welcome to peruse content the OTN Systems Community posted for sysadmins and developers over the past year, like Santa is doing:

Here's wishing that your moto start on the first kick, your engine oil run clear, your bolts not vibrate off before you reach home, your fuel not gum up your carburetor, and your face remain merrily in the wind.

Merry Christmas, or whatever you celebrate during the Holiday Season.

Two Sysadmin Articles Make OTN's Top 20

In the OTN blog, Justin reports that two sysadmin-related articles made OTN's top 20 list for 2011:

Number 2
Taking Your First Steps with Oracle Solaris 11
- by Brian Leonard and Glenn Brunette

Number 11
How I Simplified the Installation of Oracle Database on Oracle Linux
- by Ginny Henningsen

Boo-yah!

The good work of Brian, Glenn, and Ginny makes those of us in the Systems Community of OTN particularly proud because the number of OTN readers who are system admins and developers is dwarfed by the number who are Java developers. Even making the top 20 is notable. To Brian, Glenn, and Ginny, a heartfelt:

Next OTN Sysadmin Day is in Sacramento

Bottom Line: next OTN Sysadmin Day is September 8 in Sacramento.
Free, but registration is required.

One of the most subtle yet powerful skills I learned from The Missus is how to tell the difference between what was better and what I preferred.

Motorcycle magazines, for instance, spend an awful lot of time telling us why one motorcycle is better than another. They do this by employing their best interpretation of objective criteria: acceleration, braking, cornering, carrying capacity, conveniences, ergonomics, and sometimes even the personal riding experience of the reviewer.

There's nothing wrong with that. Very useful stuff. And fascinating to read. Except that it gets me all confused. Or confuzzled, as my daughter calls it. The objective criteria makes me think one bike is better than the other. But when I buy it, why am I less than fulfilled?

Because features and capabilities don't often match personal preference.

Although we don't usually put personal preference at the top of the list when choosing an operating system, we shouldn't ignore it. Personal preference is not just whim. It takes into account the job we're trying to accomplish, the way we have to handle it, and the tools we prefer to use. In fact, ignoring our personal preference has an impact on productivity: if we hate "our ride," we're not going to get very good at using it, are we?

OTN's second Sysadmin Day (read about the first) will begin with an overview of Oracle's dual OS strategy. Then we'll split off into two tracks, one with hands-on labs for Oracle Linux, one for Oracle Solaris.

Time Session
8:00 am System Shakedown
9:00 am Oracle's Dual OS Strategy
 

Oracle Solaris Track

Oracle Linux Track

9:30 am Overview of Oracle Solaris Overview of Oracle Linux
10:00 am HOL: ZFS HOL: managing packages, configuring services
11:30 am HOL: Exploring OS, network, and storage virtualization HOL on Storage Part I: managing storage and file systems
1:00 pm Lunch Break
2:00 pm HOL: Managing software with IPS HOL on Storage Part II: Device Mapper, BTRFS
3:00 pm Presentation: Oracle Enterprise Manager Ops Center 11g
4:00 pm Discussion: What are the most pressing issues for sysadmins today?
5:00 pm We all go home

Consider it an Oracle Demo Day, if you will. It's free, but you must register to attend.

As for me, after spending a couple of years riding the canyons on a 2005 Ducati 800SS, a 2003 Ducati ST4 with a 4-valve 996 engine, Ohlins shocks, and Marchesini wheels, a 2005 BMW K1200S, and the bikes of a few friends, I went back to a 2006 Harley Davidson Fat Boy. Even though the other bikes performed much better, I prefer the Fat Boy. And my wicked smaht Missus.
