Call for Papers: OTN VTS Systems Track - September 2015

If you've spent the last several months in a cave it's possible that you have not heard of the OTN Virtual Technology Summit event series. No problem -- I'll bring you up to speed.

Each event in this quarterly series is comprised of four tracks, covering Java, Database, Middleware, and of course, Systems. Within each track you'll find a selection of sessions presented by community members and members of various product teams. The sessions are deeply technical, with a focus on hands-on, how-to information.

If you're interested in presenting in the Systems track at one of these events, you can submit your session proposals in this special dedicated space on the OTN Community Platform. Please note that you must be logged in to the Community Platform in order to submit a session proposal. A Community account is absolutely free, and also entitles you to access to a wide array of discussion groups and other resources.

Systems track proposals are now being accepted for sessions covering Oracle operating systems, virtualization, or hardware for the September 2015 event. In order to be considered for the September event, proposals must be submitted by Monday July 20. Final selection will be made by July 27.

Questions? Post them as a comment, below?

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:

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).

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 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.

What Can You Do With Data Link Multipathing (DLMP)?

When I first learned about high availability, it was something you provided by creating one or more copies of the operating environment on separate servers. Sometimes on different continents. If the server in Canada failed, the server in Ireland would take over.

Then I found out about Real Application Clusters. Wait, I asked myself, weren't applications invented for the sole purpose of field-testing the OS? Why do test programs need high availability? Haven't these people heard of Oracle Solaris Cluster?

Well, to my great disappointment there are plenty of different approaches to high availability. Just like there are plenty of different approaches to virtualization. And, as you might imagine, you can combine the two.

For instance, if you're going to build a cloud infrastructure using the virtualization capabilities in Oracle Solaris 11, you might as well allocate your network resources to the virtualized environment, as well. And so, you'd probably find yourself creating virtual switches, routers, cards, and what not. Well, what happens if all those virtual networks, which are really just one physical network, go down?

Bjoern Rost, Oracle ACE, provides a nice explanation of a Solaris feature that didn't get a lot of attention when it was released: Data Link Multipathing (DLMP) and DLMP aggregation. DLMP aggregation allows you to combine virtual network interfaces from different physical network interfaces into high availability clusters. You can also use these clusters to improve load balancing, as Bjoern explains in his blog post.

Orgad likes DLMP, too. So much, in fact, that he took a break from reconfiguring the International Space Station so his kids could control it from their XBox, and wrote an article explaining how to apply DLMP to a virtual network. Two articles, in fact.

Tech Article: Using DLMP to Add High Availability to Your Network in Oracle Solaris 11.1

by Orgad Kimchi

How to combine virtual NICs from different physical NICS into a DLMP aggregation assigned to a zone, and configure the aggregation to provide failover for the zone, using Oracle Solaris 11.

Tech Article: Doing More with DLMP

by Orgad Kimchi

You can give an Oracle Solaris 11 zone exclusive access to a physical NIC. Although that approach can ensure that particular zone has full access the entire bandwidth of the NIC, it does leave NIC and the entire network exposed to security breaches. Unless you use DLMP's Link Protection capability. Orgad explains how to do that, as well as enabling resource management for your Oracle Solaris 11 virtual network, improving the availability of an NFS server, and more.

Replay of Solaris Labs From OTN Virtual Sysadmin Day

Missed OTN's last Virtual Sysadmin Day? That's OK, so did the majority of Earth's 7 billion inhabitants. A stalwart 400 did manage to pull themselves away from The Daily Grind and attend in person. To accommodate the remaining 7 billion slackers, I published videos of the Solaris hands-on labs. I'll do the same for the Oracle Linux and Virtualization sessions over the next few days.

Lab Intro - How Oracle Solaris 11 Simplifies the Life of a Sysadmin

Typical tasks and challenges in a sysadmin's work and how Oracle Solaris 11 simplifies them. Managing software packages, updating systems, managing users, monitoring system performance and diagnosing problems, assessing, assigning and redistributing system resources according to workload patterns. Which Oracle Solaris 11 features can help. Examples and best practices. Exercises that model everyday situations.

Lab 1: Managing the Software Lifecycle with Oracle Solaris 11

Tricks to help you to manage software packages installed on your systems. Most organizations have separate environments for development, test, QA and production applications. How can you make sure the right versions of software packages are installed in each of them, and avoid inconsistencies? How can you configure your production systems to avoid accidental updates? How should you integrate your software packages with SMF services? These and many other questions will be answered by using practical hands-on examples.

Lab 2: Managing Your Data with ZFS in Oracle Solaris 11

ZFS has been a round a long time, but it has so many new capabilities to explore that you might still have a lot of questions. For instance, how do I create a ZFS file system that will have a guaranteed amount of available space, instead of sharing it with other file systems in a pool? What are the best practices for backing up ZFS file systems? How can I use ZFS encryption? Can I create a raw block device on ZFS and why do I need it? These and many other questions will be answered by using practical hands-on examples.

Lab 3: Managing Virtual Environments in Oracle Solaris 11

What are the best ways to create and manage zones? How should I use Solaris virtual networking to separate traffic from different applications? How can I monitor and manage system resources assigned to zones? How should I protect my zones from malicious users? How can I migrate zones between hosts? These and many other questions will be answered with practical hands-on examples.

Which Type of Virtualization Should I Use?

I routinely ask techies which type of virtualization they'd recommend for which type of job. I seldom get an answer as crystal clear as Brian Bream's.

Video Interview: Which Type of Virtualization Should I Use?

with Brian Bream, CTO Collier IT

Oracle's portfolio of virtualization technologies includes Oracle VM Server for x86, Oracle VM Server for SPARC (previously known as LDOMS), and Oracle Solaris Zones, among others. Brian Bream provides a crystal clear technical overview of their differences and examples of what you would use them to do to. After you listen to the recording, which is about 5 minutes long, you'll understand why Brian was selected Instructor of the Year for both Oracle University and Sun Microsystems University before that.

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.

Lab - How to Deploy Oracle Software in Minutes Using Oracle VM Templates

In my first 12 years of school I had a natural ability in Math and Science, but had to work hard at English and History.

When I went to college, I didn't do well in Math and Science, so I transferred into Liberal Arts, where strangely enough, I did well. After all these years I just realized why. I never had to study for Math and Science. I just understood the material. If I did any homework, I did it during class. Which means I never listened to lectures. As a result, I never learned how to learn what I didn't know. So, when college presented me with more advanced topics that I couldn't just grok, I didn't know what to do. I fell behind. I assumed I wasn't any good. The opposite was true with Liberal Arts. Literature, History, Economics, it all confused me. So I listened in class. And I studied after class. SoI did well.

And that's why I'm not an engineer.

If you're a hands-on learner like me and Joel Schallhorn, the guy doing bicycle tricks in the picture, you'll appreciate our latest hands-on lab.

Lab: How to Deploy a Four-Node Oracle RAC 12c Cluster in Minutes, Using Oracle VM Templates

Hands-On Lab by Olivier Canonge with contributions from Christophe Pauliat, Simon Coter, Saar Maoz, Doan Nguyen, Ludovic Sorriaux, Cecile Naud, and Robbie De Meyer

This lab demonstrates how easy it is to deploy software environments with Oracle VM Templates. It uses a single-instance, Oracle Restart (Single-Instance High Availability [SIHA]), and Oracle Real Application Clusters (Oracle RAC) for Oracle Database as an example. During this lab, you are going to deploy a four-node Flex Cluster (three hubs and one leaf) with a dedicated network for Oracle Flex ASM traffic.

About our Latest Lab: How to Migrate to Oracle Linux and Oracle VM





Step by Step Instructions for Migrating to Oracle Linux and Oracle VM

Red Hat Linux and VMWare are fine technologies. A great pairing. However, if you have business reasons for migrating to Oracle Linux and Oracle VM, such as having earlier access to the latest Linux innovations or taking advantage of more integrated virtualization, take a look at our latest lab. It provides the best step by step instructions we could come up with for carrying out that migration. You can also try it just to hone your migration skills. You never know when the boss is going to ask you whether you can handle a migration.





Here's a peek at the major tasks:

  1. Start the two servers (Oracle VM Server and Oracle VM Manager).
  2. Connect to Oracle VM Manager and become familiar with the product.
  3. Verify that the Oracle VM environment started correctly.
  4. Import an assembly that has Oracle Database on top and was exported from VMware.
  5. Create an Oracle VM Template based on the VMware assembly.
  6. Edit the Oracle VM Template that was created.
  7. Create a guest based on the Oracle VM Template that was created.
  8. Verify and then start the Oracle VM guest that was created.
  9. Manually modify the guest configuration and remove VMware tools.
  10. Switch from the Red Hat kernel to Oracle's Unbreakable Enterprise Kernel for free.
  11. Transform the guest into a usable Oracle VM Template ("gold image").

You can run the lab anytime you like on your laptop, or you can attend OTN's next Virtual SA Day, and run it with the help of a proctor. There will be several hundred sysadmins running the same lab at the same time, so you can discuss it with others via chat, and get help from our proctors. Details here.

Why I'm Going Straight to Hell

Article: Performance Analysis in a Multitenant Cloud Environment

by Orgad Kimchi

My little brother and I used to drive our Sainted Mother mad with this game at bed time. We'd wait till she was stressed out, then throw something big, like a softball, against the wall. Being a worry-wart, she'd come into the room to find out which one of us had fallen out of his bed and broken his arm. We both pretended to be fast asleep, of course, and had already recovered the soft ball.

Perplexed, she would return to the kitchen. A short while later, we would throw the bat against the wall. After the initial boom against the sheetrock, it would clatter on the ground, making a sound similar to a mother's precious child cracking his skull on the cement steps in front of the house. Quickly one of us would recover it, tuck it under the sheets, and then we'd both return to our previous sleeping positions.

Little did we know, as we pushed our mother closer to the edge of Insanity, that our techniques would be adopted by virtualized environments the world over. As Orgad explains in the article above, as each virtualization product abstracts computing resources for isolation or other purposes, it creates a little brother. If something goes boom in the night or, if your environment starts hanging, how do you figure out where the problem is?

It's a super article, and well worth your time. If Mom had read it, we would have woken up inside an anthill, with only our heads sticking out so she could listen to our screams while she sipped a cup of Darjeeling.

Article: Performance Analysis in a Multitenant Cloud Environment

Performance analysis in a virtualized multitenant cloud environment is difficult because of the abstraction layers. How do you find the physical system resources that are overloaded? Orgad Kimchi explores four examples that show how you how with the built-in Oracle Solaris 11 tools.

Tech Article: How to Set Up a Hadoop Cluster Using Oracle Solaris Zones

by Orgad Kimchi

Apache Hadoop helps you process large amounts of data on multiple computers that are clustered together. Oracle Solaris zones are easy to clone and manage as a cluster. Oracle Solaris 11 has great network virtualization capabilities. Orgad walks you through all the steps required to combine these three technologies into an easy to manage big data cluster.

Blog: How to Host a Hadoop Cluster on a SPARC T4-2 Server

by Jeff Taylor

After reading Orgad's paper (see above), Jeff Taylor decided to give Orgad's suggestion a try. He had to configure an Oracle SPARC T4-2 server to store and process two types of data. One type was critical and sensitive data that required ACID transactions and had to be stored in an Oracle Database. The other was high-volume/low-risk data that had to be processed using Apache Hadoop and stored in HDFS. In this blog post he details how he used Oracle Solaris zones.

Oracle VM Deep Dives

"With IT staff now tasked to deliver on-demand services, datacenter virtualization requirements have gone beyond simple consolidation and cost reduction. Simply provisioning and delivering an operating environment falls short. IT organizations must rapidly deliver services, such as infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS). Virtualization solutions need to be application-driven and enable:"
  • "Easier deployment and management of business critical applications"
  • "Rapid and automated provisioning of the entire application stack inside the virtual machine"
  • "Integrated management of the complete stack including the VM and the applications running inside the VM."
Application Driven Virtualization, an Oracle white paper

That was published in August of 2011. The new release of Oracle VM Server delivers significant virtual networking performance improvements, among other things. If you're not sure how virtual networks work or how to use them, these two articles by Greg King and friends might help.

Looking Under the Hood at Virtual Networking

by Greg King

Oracle VM Server for x86 lets you create logical networks out of physical Ethernet ports, bonded ports, VLAN segments, virtual MAC addresses (VNICs), and network channels. You can then assign channels (or "roles") to each logical network so that it handles the type of traffic you want it to.

Greg King explains how you go about doing this, and how Oracle VM Server for x86 implements the network infrastructure you configured. He also describes how the VM interacts with paravirtualized guest operating systems, hardware virtualized operating systems, and VLANs.

Finally, he provides an example that shows you how it all looks from the VM Manager view, the logical view, and the command line view of Oracle VM Server for x86.

Fundamental Concepts of VLAN Networks

by Greg King and Don Smerker

Oracle VM Server for x86 supports a wide range of options in network design, varying in complexity from a single network to configurations that include network bonds, VLANS, bridges, and multiple networks connecting the Oracle VM servers and guests. You can create separate networks to isolate traffic, or you can configure a single network for multiple roles. Network design depends on many factors, including the number and type of network interfaces, reliability and performance goals, the number of Oracle VM servers and guests, and the anticipated workload.

The Oracle VM Manager GUI presents four different ways to create an Oracle VM network:

  • Bonds and ports
  • VLANs
  • Both bond/ports and VLANS
  • A local network

This article focuses the second option, designing a complex Oracle VM network infrastructure using only VLANs, and it steps through the concepts needed to create a robust network infrastructure for your Oracle VM servers and guests.
