New Oracle Solaris/SPARC SIG Launched by IOUG







What happens in Vegas ...










... stays in Vegas.










Well, most of it does, anyway.

Collaborate 2014, put on by the Independent Oracle User Group (IOUG), the Oracle Applications User Group (OAUG), and the Quest International User Group was terrific. Great content, great people, great event. And lots of sysadmins!

One of the most interesting things to come out of Collaborate is a new Special Interest Group (SIG) for Oracle Systems technologies, sponsored by Independent Oracle User Group (IOUG). It's called the Solaris/SPARC SIG, but the first meeting covered a lot of ground that included the other technologies in Oracle's Systems portfolio, including engineered systems, storage, networking, and optimized solutions. This perspective on Oracle Solaris is significant because the value of Oracle Solaris becomes increasingly evident when viewed from the perspective of the database, engineered systems like Oracle SuperCluster, and cloud strategies.

So keep an eye on the SIG and join us in future activities. I'll be sure to promote them here, but also keep an eye on the SIG Calendar.

Seth Miller and Ed Whalen, Oracle ACES, were kind enough to tape a couple of video interviews for the OTN Garage. I'll be posting them there soon.

Four High Performance Configurations for SuperCluster and SPARC Servers

When a surfing buddy of mine asked me to look at a banking application that runs on Solaris, I thought he'd been hit on the head by his board one too many times. Solaris is cool. Banking is not. But I looked into it, anyway, and to my surprise, I found the banking app had a certain amount of geek appeal.

If geek appeal is not enough to hold your interest, Mister Hair-on-Fire, the other reason for talking about this banking application is that it helped identify four high performance configurations for Oracle's SuperCluster and SPARC servers that might be useful for other types of applications. So keep reading. Or ...

Go directly to white paper (pdf) that describes the configurations.

What first caught my interest was the idea of a bank operating system. A traditional computer OS manages hardware devices and provides services for application software. A bank headquarters does something very similar. It manages the branches (hardware) and provides services for its operations (applications). Turns out, that's the idea behind Finacle's Core Banking Solution.

Core banking sounds dull as hell, but it's a big deal for banks. It replaces cumbersome end-of-day consolidation between branch banks and HQ. (I almost feel asleep just writing that.) In fact, centralized banks worldwide now mandate the implementation of core banking technology to prevent fraud and meet regulatory requirements.

As a result, Finacle's Core Banking Solution is designed as configurable modules with layered Service-Oriented Architecture (SOA), straight-through processing (STP) capabilities, web-enabled technology, and support for 24 x 7 operations.

But no matter how sophisticated the application, the underlying architecture can limit its performance. Not a problem! Since Finacle 10 is now available on Oracle Solaris, it can be run on the screaming fast Oracle SuperCluster or Oracle’s SPARC T-Series servers. As you might expect, Finacle tested this combination for both batch and OLTP processing and found:

  • Batch results that processed 15% more accounts and 3.2 to 3.7 times the required minimum records per second, all achieved within one third of the specified time, with plenty of CPU resources available to handle further load.
  • OLTP results that exceeded Finacle acceptance criteria with more users and more transactions per second, all with sub-second response times and with considerable CPU resources remaining available.

White Paper: Infosys Finacle Core Banking Solution on Oracle SuperCluster and Oracle’s SPARC T-Series Servers

Roger Bitar provides technical details about the software and hardware layers in this solution, and describes the configurations that obtained the best performance:

  • Configuration for Fastest OLTP Processing on SuperCluster T4-4
  • Configuration for Fastest Batch Processing on SuperCluster T4-4
  • Configuration for Fastest OLTP Processing on SPARC T4-4 Server
  • Configuration for Fastest Batch Processing on SPARC T4-4 Server

Configuring COMSTAR to Provide Local iSCSI Storage

Oracle Solaris 11 introduced two storage capabilities that I wasn't aware of until Oracle ACE Alexandre Borges brought them to my attention.

A Solaris 11 system can serve as an iSCSI target that offers storage to other machines, or as an iSCSI initiator to access the storage offered by another iSCSI target. This capability is a real advantage, because any storage offered through the iSCSI protocol is available to an iSCSI initiator as local storage, without the need to use expensive technologies such as Fibre Channel (FC).

Solaris provides this service through a framework named Common Multiprotocol SCSI TARget (COMSTAR). Alexandre Borges shows you how to use it:

Tech Article: Using COMSTAR and ZFS to Configure a Virtualized Storage Environment

How to use COMSTAR to provide local iSCSI storage for any service that runs in Windows, Linux, or Mac OS. It also shows you how to configure authentication using the Challenge Handshake Authentication Protocol (CHAP) to secure the iSCSI storage against forbidden access. Part 1 of a series about ZFS.

About Alexandre Borges

Alexandre Borges is an Oracle ACE who worked as an employee and contracted instructor at Sun Microsystems from 2001 to 2010 teaching Oracle Solaris, Oracle Solaris Cluster, Oracle Solaris security, Java EE, Sun hardware, and MySQL courses. Nowadays, he teaches classes for Symantec, Oracle partners, and EC-Council, and he teaches several very specialized classes about information security. In addition, he is a regular writer and columnist at Linux Magazine Brazil.

More content from Alexandre:

Exploring Installation Options and User Roles in Oracle Solaris 11

Part 1 of a two-part series that describes how Alexandre installed Oracle Solaris 11 and explored its new packaging system and the way it handles roles, networking, and services. This article focuses first on exploring Oracle Solaris 11 without the need to install it, and then actually installing it on your system.

Exploring Networking, Services, and the New Image Packaging System in Oracle Solaris 11

Alexandre walks you through the new way Oracle Solaris 11 manages networking, services, and packages, compared to the way it managed them in Solaris 10.

Preserving Unpacked Software During a Package Uninstall

I love it when I can wriggle out of the unintended side effects created by an automated system designed to simplify my life.

Here's a side effect created by the very good Image Packaging System (IPS) in our beloved Oracle Solaris 11. If you use the IPS to uninstall all packaged content from a directory, it also removes the directory. Not good if you also kinda sorta loaded unpackaged content into that directory.

For instance, let's say you worked with a third-party IPS package that installed its software into /usr/local. After a pause to polish the chrome on your custom Softail Deluxe, you install a second application into /usr/local from a tar file. What happens to that second application when you use IPS to remove the third-party IPS package from the /usr/local directory? Yup. IPS dumps the directory on the asphalt and high-sides the unpackaged content all the way to /var/pkg/lost+found.

Thank goodness somebody watches out for those of us who don't follow directions. Alta Elstad, from the Solaris Documentation Team at Oracle, is one of them. Here's how she suggests you avoid this problem.

How to Preserve the Directory

To prevent the packaged directory from being removed along with its content, package the directory separately. Create an IPS package that delivers only the one directory or directory structure that you want. Then that directory structure will remain in place until you uninstall that specific package. Uninstalling a different package that delivers content to that directory will not remove the directory.

Here's a detailed example.

  1. Create the directory structure you want to deliver. This example shows /usr/local. You could easily expand this to include /usr/local/bin and other subdirectories if necessary.
    $ mkdir -p usrlocal/usr/local
  2. Create the initial package manifest.
    $ pkgsend generate usrlocal | pkgfmt > usrlocal.p5m.1
    $ cat usrlocal.p5m.1
    dir path=usr owner=root group=bin mode=0755
    dir path=usr/local owner=root group=bin mode=0755
  3. Create a pkgmogrify input file to add metadata and to exclude delivering /usr since that directory is already delivered by Oracle Solaris. You might also want to add transforms to change directory ownership or permissions.
    $ cat usrlocal.mog
    set name=pkg.fmri value=pkg://site/usrlocal@1.0
    set name=pkg.summary value="Create the /usr/local directory."
    set name=pkg.description value="This package installs the /usr/local \
    directory so that /usr/local remains available for unpackaged files."
    set name=variant.arch value=$(ARCH)
    <transform dir path=usr$->drop>
    
  4. Apply the changes to the initial manifest.
    $ pkgmogrify -DARCH=`uname -p` usrlocal.p5m.1 usrlocal.mog | 
      pkgfmt > usrlocal.p5m.2
    $ cat usrlocal.p5m.2
    set name=pkg.fmri value=pkg://site/usrlocal@1.0
    set name=pkg.summary value="Create the /usr/local directory."
    set name=pkg.description value="This package installs the /usr/local \
    directory so that /usr/local remains available for unpackaged files."
    set name=variant.arch value=$(ARCH)
    <transform dir path=usr$->drop> 
    
  5. Check your work.
    $ pkglint usrlocal.p5m.2
    Lint engine setup...
    Starting lint run...
    $
    
  6. Publish the package to your repository.
    $ pkgsend -s yourlocalrepo publish -d usrlocal usrlocal.p5m.2
    pkg://site/usrlocal@1.0,5.11:20140303T180555Z
    PUBLISHED
    
    
    
  7. Make sure you can see the new package that you want to install.
    $ pkg refresh site
    $ pkg list -a usrlocal
    NAME (PUBLISHER)      VERSION      IFO
    usrlocal (site)       1.0          --- 
    
  8. Install the package.
    $ pkg install -v usrlocal
               Packages to install:         1

    Updating search index                            1/1
    
  9. Make sure the package is installed.
    $ pkg list usrlocal

Oracle Solaris 11 Resources for the AIX Sysadmin

Start buttons belong on Tiger Wood's golf cart. Give me car keys that jangle when I insert them into a 1968 Dodge Charger. The music that engine makes ... it enters your body through your soul before your ear drums even register the vibration. And give me Save buttons on browser-based interfaces, too. This amorphous invisible background save that I'm supposed to trust is happening is the brainchild of developers who put posters of Joseph Stalin on their walls.

In spite of my Luddite tendencies, I do like new technologies. I also like a variety of them. If you ask my personal opinion, the more operating systems, the better. More jobs for sysadmins. More jobs for developers. More arm-wrestling matches in the server room. And more interesting problems. That's my idea of fun.

Unfortunately, it's not The Man's idea of fun. Forces I can't possibly understand and would never take for a joy ride in a stolen Dodge Charger push for consolidation and cost-cutting with the frenzy of a four barrel carburetor sucking air at wide open throttle (WOT). Even if, like me, you prefer a more genteel IT environment, you have to adapt. And so, we sometimes wave good-bye to our friends.

If you're facing a migration away from AIX, consider Oracle Solaris. Yeah, it's designed to handle the competitive pressures of today's IT environments...

  • Cloud-ready provisioning, security, and virtualization
  • Quick to reallocate compute, storage, and network resources
  • Zones, ZFS, Dynamic Tracing, Predictive Self Healing and Trusted Extensions reduce downtime and simplify the application deployment
  • Optimized to run on Oracle hardware, and to run Oracle applications
  • Automated migration tools plus assistance and education for DBAs and Power/AIX administrators migrating to Oracle Solaris.

... and yeah, because the Oracle stack is optimized to run best on Oracle Solaris (and Oracle Linux), it gives you some crazy good numbers compared to AIX ...

  • Up to 2.4x greater database performance
  • Up to 3.4x faster Java application server performance
  • Increased Oracle application performance : 1.9x faster for Siebel CRM (4) and 3x faster for JD Edwards

... but it's also got soul. And it doesn't have a dumb Start button.

Below is a link to a hands-on lab and some other resources to help you understand what's involved in migrating from AIX to Oracle Solaris.

Hands-On Lab: Oracle Solaris Administration for AIX Sysadmins

by Glynn Foster

Walks an AIX sysadmin through the basic administration of Oracle Solaris 11 and how it compares to IBM AIX Enterprise in areas including installation, software packaging, file systems, user management, services, networking, and virtualization. Even makes helps you navigate your way through documentation, man pages, and online how-to articles.

If Your Processor Stalls From a Read After Writer Operation ...

... rewrite your code. Better yet, write code that avoids this problem in the first place. The problem can occur when an application wants to load a value that it has just stored in memory. Read After Write (RAW) operations are common, so most chips are designed with hardware that makes that happen fast. But in some cases, you can write code that stumps the hardware. And so it stalls.

And you tumble to earth in horror, screaming for your life and clawing at the controls.

And you smack into the a pile of rocks. Or, to the horror of young mothers in minivans, the freeway during rush-hour traffic. Or worse, the middle of the ocean, so that if you somehow survive the impact, you drown. And nobody finds your body. And your loved ones can never move on.

Unless you're wearing a parachute. Like the one we just published from Darryl Gove.

Tech Article: Avoid Performance Loss (And a Fiery Death) from RAW Hazards

by Darryl Gove

Darryl explains exactly how a processor can stall from a bad RAW operation, and the common situations that cause this problem. Then he shows you how to identify, fix, and avoid writing that kind of code. Examples included. Help your loved ones move on. Read Darryl's article.

Getting Your Hands Dirty with Load Balancing

What Does the Integrated Load Balancer Do?

According to the Oracle Solaris 11 documentation, the Integrated Load Balancer (ILB) intercepts incoming requests from clients, decides which back-end server should handle the request based on load-balancing rules, and then forwards the request to that server. By spreading one server's work load across multiple servers, ILB improves reliability, minimizes response time, and improves performance of the server.

The documentation describes features, components, how it works, and even the command line interface. The docs help you understand what your load balancing toolset is, but if you want to get your hands dirty, try this:

Hands-On Lab - Deploying the Integrated Load Balancer in 60 Minutes

by Amir Javanshir

This is a cool lab because it walks you through the steps that set up an environment that enables you to play with the load balancer. The steps consist more or less of:

  • Installing Solaris
  • Setting up the virtual switches and their VNICs
  • Configuring the zone for the load balancer, including its access to the VNICs
  • Cloning that zone into three other zones
  • Configuring each cloned zone to run Apache Tomcat
  • Installing the load balancer on the first zone

Once the environments are set up, the lab walks you through several exercises to help you become familiar with the different ways in with the load balancer monitors and manages traffic. This lab is a whole lot of fun.

Man Vs. Machine

Man vs machine. Command Line vs GUI. It's not a new debate. In fact, when I was a little boy I watched this Paul Bunyan cartoon with the dismay of a sysadmin watching the increasing popularity of GUIs:

Cartoon: Paul Bunyan's Ax vs The Chain Saw

What Skills Do Sysadmins Need to Manage a Modern Data Center?

Video Interview with Brian Bream

When I wrote technical manuals for Oracle Solaris back in the day, I had the luxury of my very own lab. For instance, while writing the NIS+ books, I was able to discover my own procedures on a small network and, when I needed something larger, I could ask the sysadmins in Sun's bigger labs to try some experiments for me. Little did I know those were the Golden Years of technical writing.

They were also the Command Line Years. We used the command line for everything, including email, product testing and, of course, managing Solaris. The command line put the operator in control. You had a mental map of what you were doing, you were completely engaged, and if something became repetitive, you could always write a script for it. The shell was the interface, and emacs was the only tool you needed.

When GUI's first came out, we hated them on principle. They were slower than the command line, and they didn't really add any value. Plus, they weakened your skills.

Since then it's been a tossup. GUI's have gotten steadily better, but they didn't add enough value to overcome our attachment to the command line. In fact, we kinda resented them because they were used as a pretext to hire less experienced and cheaper sysadmins.

However, with the advent of vertically-integrated systems such as Oracle's Exadata and SuperCluster, the GUI may have finally come into its own. Listen to Brian Bream explain why.

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.

Life could be a dream
If I could take you up in paradise up above
If you would tell me I'm the only one that you love
Life could be a dream, sweetheart

Hey nonny ding dong, alang alang alang (ha-doop)
Ba-doh, ba-doo ba-doodle-ay
Life could be a dream
Life could be a dream, sweetheart!

Life could be a dream
If only all my precious plans would come true
If you would let me spend my whole life loving you
Life could be a dream, sweetheart

How to Limit Upgrades Beyond a Prescribed Version of Oracle Solaris

by Bart Smaalders and Alta Elstad

The Oracle Solaris 11 Image Packaging System (IPS) provides various methods to control the operating system version to which a server can be upgraded. One method is to provide a custom incorporation package.

An incorporation package specifies the versions of other packages that can be installed. An incorporation package ensures that if you install an incorporate dependency package of that incorporation package, only the prescribed version of the dependent package can be installed. You can create your own custom incorporation package to specify the constraints you want. Using a custom incorporation to control the version of software that can be installed enables you to easily maintain different versions of Oracle Solaris on different machines without maintaining multiple package repositories. Each image can install a different version of the custom upgrade control incorporation package. All systems share the same package repository that contains all versions of software needed by any of the systems.

In the example in this article, a system has been newly installed with Oracle Solaris 11.1. The solaris publisher origin is the Oracle Solaris support repository, which includes many updates since Oracle Solaris 11.1 was released. The IT department in the example company has not yet qualified the most current support updates, and they want to limit administrators to upgrading to only the latest update that is qualified for their environments, not the latest update that is available from the package repository.

Create a Custom Incorporation Package

The versions of core operating system packages that can be installed in an image are controlled by the pkg:/entire incorporation package. To control system upgrades, create a package that specifies a particular version of the pkg:/entire package as an incorporate dependency.

The following example shows a manifest named upgradectrl.p5m for a custom incorporation package that controls the version of the pkg:/entire package that can be installed. Some of the settings in this manifest are described below.

set name=pkg.fmri value=upgradectrl@1.0
set name=pkg.summary value="Incorporation to constrain the version of the OS"
set name=pkg.description value="This package controls the version of \
pkg://solaris/entire that can be installed."
set name=info.classification value="org.opensolaris.category.2008:Meta Packages/Incorporations"
set name=pkg.depend.install-hold value=core-os
set name=variant.opensolaris.zone value=global value=nonglobal
set name=variant.arch value=sparc value=i386
depend fmri=feature/package/dependency/self type=parent variant.opensolaris.zone=nonglobal
depend fmri=pkg://solaris/entire type=require
depend fmri=pkg://solaris/entire@0.5.11,5.11-0.175.1.0 type=incorporate
  • pkg.depend.install-hold This setting ensures that if a user updates the upgradectrl package, the pkg:/entire package is automatically updated as well.

  • variant.opensolaris.zone This setting enables this package to be installed in both global and non-global zones. See also the description of the parent dependency.

  • variant.arch This setting enables this package to be installed on both SPARC and x86 systems.

  • parent dependency This package can be installed in a non-global zone only if it is already installed in the global zone.

  • require dependency The upgradectrl package can be installed only if the pkg://solaris/entire package is already installed or can be installed in this same operation.

  • incorporate dependency The pkg://solaris/entire package must be installed at the specified version. More than one version can satisfy an incorporate dependency, depending on how many places of accuracy are specified. In this example, 0.175.1.0 specifies Oracle Solaris 11.1 SRU 0. This upgrade control package will keep systems at the newly installed Oracle Solaris 11.1 version, no support updates. This upgrade control package will, however, allow packages that are not contrained by the pkg:/entire incorporation to be updated.

Publish the upgradectrl package to a local file-based repository. This repository is for developing and testing this new package. If you create a repository for general use, you should include additional steps such as creating a separate file system for the repository. For information about creating package repositories for general use, see Copying and Creating Package Repositories in Oracle Solaris 11.2.

Create a package development repository on your system. See the pkgrepo(1) man page for more information about the pkgrepo command.

$ pkgrepo create myrepo

Set the default publisher for this repository. The default publisher is the value of the publisher/prefix property of the repository.

$ pkgrepo -s myrepo set publisher/prefix=site

Publish the upgradectrl package to the development repository.

$ pkgsend -s myrepo publish upgradectrl.p5m
pkg://site/upgradectrl@1.0,5.11:20131120T010105Z
PUBLISHED

Notice that the repository default publisher has been applied to the package FMRI.

Examine the repository to confirm that the package was published.

$ pkgrepo -s myrepo list
PUBLISHER NAME                                       O VERSION
site      upgradectrl                                  1.0,5.11:20131120T010105Z
$ pkg list -vg myrepo
FMRI                                                                         IFO
pkg://site/upgradectrl@1.0,5.11:20131120T010105Z                             ---

Deliver the package to a local repository in a separate ZFS file system in a shared location.

$ pkgrecv -s myrepo -d /export/IPSpkgrepos/Solaris upgradectrl

Update the Upgrade Control Package

When you are ready to allow users to upgrade their systems to a new version, update the upgradectrl.p5m manifest, and republish and redeliver the new upgrade control package. In the following manifest, the version of the upgrade control package and the version of the pkg:/entire incorporation are updated. As an aid for users, the version of the upgrade control package matches the updated version of the pkg:/entire package.

set name=pkg.fmri value=upgradectrl@1.10
set name=pkg.summary value="Incorporation to constrain the version of the OS"
set name=pkg.description value="This package controls the version of \
pkg://solaris/entire that can be installed."
set name=info.classification value="org.opensolaris.category.2008:Meta Packages/Incorporations"
set name=pkg.depend.install-hold value=core-os

depend fmri=pkg://solaris/entire type=require
depend fmri=pkg://solaris/entire@0.5.11,5.11-0.175.1.10 type=incorporate

The following commands republish and redeliver the upgrade control package:

$ pkgsend -s myrepo publish upgradectrl.p5m

Upgrade the Image

The following pkg update command updates all packages to the newest available versions allowed because no packages are specified. The command updates to the newest available version of the upgrade control package, which upgrades the image because the pkg.depend.install-hold setting in the upgradectrl package causes the pkg:/entire package to be updated when the upgradectrl package is updated. The image is upgraded to the version of the pkg:/entire incorporation that is specified in the new upgradectrl incorporation.

Understanding Process Scheduling in Oracle Solaris

The process scheduler in the Oracle Solaris kernel allocates CPU resources to processes. By default, the scheduler tries to give every process relatively equal access to the available CPUs. However, you might want to specify that certain processes be given more resources than others. That's where classes come in. A process class defines a scheduling policy for a set of processes. These three resources will help you understand and manage it process classes:

Who Is Right - the Hardware or the Software?

Michael Palmeter and Renato Ribeiro enjoy a good duel. Michael represents Oracle Solaris. Renato represents SPARC servers. Watch and listen as they argue their case on two questions of interest to sysadmins. Taped at Oracle OpenWorld 2013.

What Determines Performance - The Hardware or the Software?

Michael Palmeter vs Renato Ribeiro

Is the hardware or the software more important to the performance of a system? Oracle Solaris product director Michael Palmeter goes mic-to-mic with Renato Ribeiro, Oracle SPARC Director. Taped at Oracle OpenWorld 2013.

What Kind of Scalability is Better - Horizontal or Vertical?

Renato Ribeiro vs Michael Palmeter

Is Oracle's approach to large vertically scaled servers at odds with today's trend of combining lots and lots of small, low-cost servers systems with networking to build a cloud, or is it a better approach? Michael Palmeter, Director of Solaris Product Management, and Renato Ribeiro, Director Product Management for SPARC Servers, discuss.

Screencast: Outliers

In this screencast, Jon Haslam describes how the Oracle Database and Oracle Solaris engineering teams worked together to integrate DTrace and V$ Views to provide a top-to-bottom picture of a database transaction I/O -- from storage devices, through the Oracle Solaris kernel, up to Oracle Database 12c itself. With this end-to-end view, you can easily identify I/O outliers -- transactions that are taking an unusually long time to complete -- and use this comprehensive data to identify and mitigate storage system problems that were previously extremely hard to debug. link

And Don't Forget ...

WebCast: Introducing Oracle Database 12c

Oracle prez Mark Hurd and friends will be talking about the pluggable databases capability in Oracle Database 12c’s new multitenant architecture. No, they do not let you pause a running database with a cork, unfortunately, but they do make it easy to consolidate onto the cloud. Topics covered:

  • Simplify database consolidation
  • Automatically compress and tier data
  • Improve database and application continuity
  • Redact sensitive data
  • And as an added bonus, hear Tom Kyte’s “Top 12 Features of Oracle Database 12c.”

How Oracle Solaris Makes the Database Scream

Few things are as satisfying as a screaming burnout (image removed from blog). When Oracle Database engineers team up with Oracle Solaris engineers, they do a lot of them. Here are a few of the reasons why.

Article: How the OS Makes the Database Fast - Oracle Solaris

For applications that rely on Oracle Database, a high-performance operating system translates into faster transactions, better scalability to support more users, and the ability to support larger capacity databases. When deployed in virtualized environments, multiple Oracle Database servers can be consolidated on the same physical server. Ginny Henningsen describes what Oracle Solaris does to make the Oracle database run faster.

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?

Monday, July 15 at 9:00 am Pacific Time. (Time converter here.)

What If I Want to Update Just Java?

Sometimes all you want to update is Java, and not your entire Oracle Solaris environment. But Java is packaged as part of the Oracle Solaris systems software, and Oracle recommends that you update all the system software at once, since it was tested together.

What can you do?

How to Update Only Java in Your Oracle Solaris Environment

by Peter Dennis and Alta Elstad

This article describes how to update one piece of software that is constrained by an incorporation without altering any other software that is constrained by that incorporation, and still end up with a supported system. This article by Peter Dennis and Alta Elstad explains how to do that. It focuses on Java, but you can use the same technique for other software.

How to Build A Cloud for Family and Friends Using Oracle Solaris 11

image copyright 2013 by Rick Ramsey

When we talk about cloud, we tend to focus on The Cloud. Enterprise. Government. Scalable. Fast. Big. Bigger. Fastest. That's all wicked impressive, but it's not something I can do on a rainy Saturday afternoon. Now, I like and use Dropbox. There are other easy-to-use cloud services out there similar to Dropbox. But my Inner Geek wants his own cloud. Something modest and unassuming. Itty bitty, even. Just for fun. Kinda like putting a race cam on my Ducati 748: I don't need one, but I want to see if I can do it. Turns out it's nowhere near as involved as installing a race cam on a Ducati. And you don't need to get your hands greasy. Suk Kim, Oracle ACE Director, shows how.

How to Build a Web-Based Storage Solution Using Oracle Solaris 11

by Suk Kim, Oracle ACE Director

Combine AjaXplorer, Oracle Solaris 11.1, and Apache Web server to build a cloud-based storage service that is similar to Dropbox. These are the main tasks ... Install Oracle Solaris 11.1. Configure ZFS storage. Install the Apache and PHP packages. Set up Security. Connect to the client. Check ZFS compression and deduplication. That's all it takes. Suk Kim provides the instructions.

(In case it's not clear that the link is in the heading, Laura, you can also click here)

Suk Kim is an Oracle Ace Director for Oracle Solaris in South Korea. He is also chairman of the Korea Oracle Solaris User Network, manager of Oracle Solaris TechNet, manager of the Solaris School community, an adjunct professor at Ansan University, and a senior system and security consultant at NoBreak Co., LTD.

About the Cloud Picture

I took it from my house in Colorado in the summer of 2011 with a cheap Sony camera. 2013 has brought a snowy Spring to Colorado (next storm, on May 1, will drop 6 inches of snow on us), so it's likely we'll see a lot more of these storms in May, June, and July. I need to spring for a better camera so you can see how spectacular these storms are in the high country.

The Sysadmin as CEO

Bjoern Rost began his professional life as a sysadmin, and no doubt through the clever use of scripts became the CEO of his own consulting company (image removed from blog). Oracle recently announced his appointment to Oracle ACE Director. Here's some background information about Bjoern and his company, a video interview, and links to his most recent blog posts.

About Bjoern Rost, Oracle ACE Director

Bjoern is the co-founder of Portrix Systems, a service provider and consulting company focused on Oracle technologies including servers, storage, Solaris, Real Application Cluster databases, and desktop virtualization. He enjoys working with software developers to tightly integrate with existing Oracle features, is passionate about sharing knowledge, and has enjoyed speaking at several conferences and user group meetings including OpenWorld, UKOUG, COLLABORATE and DOAG. He also serves as the European Chair of IOUG's RAC special interest group.

Interview with Bjoern at Oracle Open World 2012

Before I knew that Bjoern was even being considered for Oracle ACE Director, I had the good fortune of chatting with him at Oracle Open World 2012. He's an excerpt from our conversation:

A Sysadmin CEO's Favorite Technologies in Oracle Solaris 11
Bjoern Rost, Orace ACE Director, was a sysadmin before he co-founded a consulting company, Portrix Systems. He describes how that happened, which Oracle technologies he used, what he used them for, and what his favorite parts of Oracle Solaris 11 are. Bonus: how engineered systems are leading to a confluence of the system admin and the database admin.

Bjoern's Blog

Bjoern's Blog is actually a team blog with contributions from three Euro-techies named Florian, Markus, and Ole. Recent topics are:

About Portrix Systems

Portrix Systems, an Oracle Gold Partner, is a full service provider helping customers run and operate complex IT systems by integrating infrastructure and services. From their home page:

"We started as the internal system administration division of the PORTRIX group. Duties involved setting up test and development systems for software developers and consulting about their optimal use. This soon evolved into services we provided for our customers who leveraged the potential to receive ISV software products bundled with integration and operation services by the same people who were already involved in development.

Congratulations, Bjoern! We're very glad to have you with us.

Why Solaris Loves Python

It's not well known that Oracle Solaris 11 includes a healthy dose of Python code, and that Solaris engineering uses Python tools. These four videos provide more of the story.

How Oracle Solaris 11 Uses Python

Oracle Solaris 11 installation tools use Python to access C libraries more quickly and easily than if they were coded in C. Drew Fisher explains why the Solaris engineering team chose Python for this purpose, what he personally likes about it, and what it implies for the future of Solaris development.

Why Is Oracle Solaris Engineering Looking for Python Developers?

Martin Widjaja, engineering manager for Oracle Solaris, describes the development environment for Oracle Solaris and why Oracle wants to hire more Python developers to work on Solaris.

Why I Started Developing In Python

David Beazly was working on supercomputing systems at Los Alamos National Laboratory when he began to use Python. First, he used it as a productivity tool, then as a control language for C code. Good insights into Python development for both systems developers and sysadmins from the respected author.

How RAD Interfaces In Oracle Solaris 11 Simplify Your Scripts

Every time a new release of Oracle Solaris changes the syntax or output of its administrative commands, you need to update any scripts that interact with those commands. Until now. Karen Tung describes the RAD (Remote Administration Daemon) interfaces that Solaris 11 now provides to reduce the need for script maintenance.

Evaluating Oracle Solaris and Oracle Linux From Your Laptop

Evaluating Oracle Linux From Inside VirtualBox

After importing your Oracle Linux virtual image, you can use the yum install command to download additional packages into your Linux environment. Yuli explains how.

But what's really cool about evaluating an OS from inside VirtualBox is that you can assign each virtual image a unique IP address, and have it communicate with the outside world as if it were its own physical machine on the network. Yuli describes how to do this, and also how to install guest additions to, for instance, share files between the guest and host systems.

Evaluating Oracle Solaris 11 From Inside VirtualBox

In this article Yuli shows you how to create and manage user accounts with either the GUI or the CLI, how to set up networking, and how to use the Service Management Facility (SMF) to, for instance, control SSH connections to the outside world.

Both article cover the basics to get you started, but also very valuable are the links that Yuli provides to help you move further along in your evaluation.
