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.

Why Move My Oracle Database to New SPARC Hardware?

If you didn't manage to catch all the news during the proverbial Firehose Down the Throat that is Oracle OpenWorld, you'll enjoy these short recaps from Brad Carlile. He makes things clear in just a couple of minutes. photograph copyright by Edge of Day Photography, with permission

Video: Latest Improvements to Oracle SPARC Processors

with Brad Carlile

T5, M5, and M6. Three wicked fast processors that Oracle announced over the last year. Brad Carlile explains how much faster they are, and why they are better than previous versions.

Video: Why Move Your Oracle Database to SPARC Servers

with Brad Carlile

If I'm happy with how my Oracle Database 11g is performing, why should I deploy it on the new Oracle SPARC hardware? For the same reasons that you would want to buy a sports car that goes twice as fast AND gets better gas mileage, Brad Carlile explains. Well, if there are such dramatic performance improvements and cost savings, then why should I move up to Oracle Database 12c?

Migrating from SUSE Linux to Oracle Linux - System Initialization

The iptables service defines rules for handling packets on a Linux system. It's usually a good idea to disable this service during installation of a Linux update to prevent malicious code from being installed by angry cats (image removed from blog). Once the update is installed securely, you can define the iptables rules and once again enable the service.

To find out, before you install an update to Oracle Linux, whether the iptables service is enabled, use the list option to the chkconfig command. It displays the status of Linux services at boot time. For example:

# chkconfig -- list
abrtd 0:off 1:off 2:off 3:on 4:off 5:on 6:off
acpid 0:off 1:off 2:off 3:off 4:off 5:off 6:off
atd 0:off 1:off 2:off 3:on 4:on 5:on 6:off
...
...
iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off
...
...

...
...

To check the status of only the iptables service, pipe in a little grep:

chkconfig -- list | grep iptables

This is just one of the tips provided by Manik Ahuja and Kamal Dodeja in their OTN technical article, ....

Tech Article: How to Initialize an Oracle Linux System

This is the first in a series of articles that outline the major steps in migrating from SUSE Linux to Oracle Linux. It focuses on registering your system, downloading the latest version of Oracle Linux, and performing some basic initialization steps. Stay tuned for more articles.

Migrating to Oracle Linux: How to Identify Applications To Move

source

One of the first things you need to make when migrating from SUSE Linux to Oracle Linux is an inventory of your applications. A package management tool such as Yet Another Setup Tool (YAST) is a big help here. So is the rpm command. Here are some ways to use it.

To List All The Installed Packages

Use the -qa option.

# rpm –qa
filesystem-11.1.3.5.3
sles-release-DVD-11.2.1.234
...

To Save the Output in a File

You can move that file to any location and, anytime later,search through the package list saved there to look for a package of interest:

# rpm –qa > rpmlist.txt

To Sort the Packages

To see the installed packages sorted by install time, use --last. The packages installed most recently will appear at the top of the list, followed by the standard packages installed during the original installation:

# rpm –qa --last
VirtualBox-4.2-4.2.6_82870_sles11-0-1
...

To Find Out If A Particular Component Is Installed

To find out whether a particular component is installed and what version it is, use the name option. For example:

# rpm –qa python
python-2.6.0-8.12.2

To Find Out What Dependencies a Package Has

Use the -qR option:

# rpm –qR python-2.6.0-8.12.2
python-base = 2.6.0
rpmlib(VersionedDependencies) <= 3.0.3-1
...

We Need More Migration!

source

Eva Mendez says, "Oye chico, do you really want to keep your data in that tired legacy file system when it could be enjoying encryption, compression, deduplication, snapshots, remote replication and other benefits provided by ZFS in Oracle Solaris 11?

It's really not that hard to cross over. If you know how."

"I don't know how, me dices? Esta bien, papacito. Go to OTN. Take my word for it. They know how."

<blushing>
Aw shucks, Eva. Anything for you!
</blushing>

The Best Way to Migrate Data From Legacy File Systems to ZFS

To migrate data from a legacy filesystem to ZFS in Oracle Solaris 11, you need to install the shadow-migration package and enable the shadowd service. Then follow the simple procedure described by Dominic Kay.

How to Update to Oracle Solaris 11 Using the Image Packaging System

Oracle Solaris 11.1 has been released. You can upgrade using either Oracle's official Solaris release repository or, if you have a support contract, the Support repository. Peter Dennis explains how.

How to Migrate Oracle Database from Oracle Solaris 8 to Oracle Solaris 11

How to use the Oracle Solaris 8 P2V (physical to virtual) Archiver tool, which comes with Oracle Solaris Legacy Containers, to migrate a physical Oracle Solaris 8 system with Oracle Database and an Oracle Automatic Storage Management file system into an Oracle Solaris 8 branded zone inside an Oracle Solaris 10 guest domain on top of an Oracle Solaris 11 control domain.

You Don't Want to Meet Orgad Kimchi in a Dark Alley

source

Do you remember what those bad guys in the old Charles Bronson films looked like? They looked like Orgad Kimchi, that's what they looked like. When I met him at Oracle OpenWorld 2012, I realized I didn't want to meet him in the wrong alleyway of Budapest after dark.

Neither do old versions of Oracle Solaris, which Orgad bends to his will with as much ease as he probably bends stray tourists to his will in Budapest, Kandahar, or Dagestan.

How Orgad Made Oracle Database Migrate from Oracle Solaris 8 to Oracle Solaris 11

In this article, which we liked so much we reprinted it from his blog (please don't tell him!), Orgad explains how he head-butted an Oracle Database into submission. The database thought it was safe running in Oracle Solaris 8, but Orgad dragged its whimpering carcas into Oracle Solaris 11. How'd he do that? Well, if you had met Orgad in person, you wouldn't ask that question. Because you'd know he could have simply stared at it, and the database would have migrated on its own.

But Orgad didn't do that. Instead, he stuffed an Oracle Solaris 8 Physical-to-Virtual (P2V) Archiver Tool into his leather trench coat, the one with the special pockets sown in by the East German Secret Police for several Uzis and their ammo, and walked into his data center in a way that reminded the survivors of this clip from Matrix Reloaded.

The end result? The Oracle Database 10.2 that was running on Oracle Solaris 8 is now running inside a Solaris 10 branded zone in Oracle Solaris 11. With no complaints.

Don't make Orgad angry. Read his article.

Excuses, Excuses!

Excuses BookThere are two kinds of sysadmin. One charges into the unknown, eager to try the latest-and-greatest, confident in his or her ability to fix whatever breaks. The other is cautious, dedicated to keeping the Enterprise running and probably aware that unplanned downtime can become one of those career-limiting events.

If you are the latter, you probably have a pile of valid reasons (polite version of "excuse") why you haven't upgraded from Oracle Solaris 10 to Oracle Solaris 11. But that pile is getting pretty small. One of the remaining challenges may be how to get from here to there with minimal downtime. Fortunately, Harold Shaw has written an article that takes fear, pain, and loathing out of that migration: How to Live Install from Oracle Solaris 10 to Oracle Solaris 11 11/11.

You'll notice that we are being very specific that this will get you to Oracle Solaris 11 11/11. In fact, there are a couple of very important caveats: not only is this how-to (currently) specific to a target OS of Oracle Solaris 11 11/11, Harold is careful to point that you can't create a golden image on one type of system, say a SPARC M-Series system from Oracle, and deploy it on a different system, such as a SPARC T-Series system from Oracle.

The 4 Steps to Migrating from Oracle Solaris 10 to 11 11/11

Harold's formula is very detailed and surprisingly concise. I'd say you are running out of excuses to not make that switch to Oracle Solaris 11.

Does Your Weekend Workload Look Like This?

We have a couple of resources to help you dive under.

Article: How Dell Migrated From SUSE Linux to Oracle Linux

In June of 2010, Dell made the decision to migrate 1,700 systems from SUSE Linux to Oracle Linux, while leaving the hardware and application layers unchanged. Suzanne Zorn worked with Jon Senger and Aik Zu Shyong, from Dell, to understand exactly how Dell did it. In this article, they describe Dell's server environment, the migration process, and what they learned. The article covers:

  • Preparation, including the use of a "scratch" area
  • Archiving configuration files
  • Conversion of MPIO to PowerPath with a custom script
  • Re-imaging the new OS and installing with kickstart
  • Restoring the configuration files
  • Adjusting profiles
  • Restarting database and applications, and verifying correct operation.

More about Oracle Linux here.

Demo: Update the Oracle Linux Kernel with Ksplice

Waseem Daher uses the command line to demonstrate how you can use Ksplice to install kernel updates to Oracle Linux without rebooting, even while your applications are still running. He also shows you how to use the Uptrack utility in Ksplice to manage your Linux packages more easily. It's only 18 minutes long, and well worth your time.

Why big wave surfers do it.

Sun.com Will NOT Disappear After June 1 (Corrected)

A few days ago I wrote:

The www.sun.com site will be decommissioned on June 1 of this year.

In the comments I went on to say that I doubted there would be 1:1 redirects.

I was wrong. (Don't tell my wife I'm capable of saying that!) The www.sun.com domain will NOT be decommissioned or sold on June 1 of this year. Rather, sun.com URLs will redirect to oracle.com URLs, with 1:1 redirects where possible.

Most of the content that was on BigAdmin, OpenSolaris.com, and some sections of SDN has already been migrated to the System Admin and Developer Community of the Oracle Technology Network (OTN).

Our engineering team is working on a solution for the Hardware Compatibility List. I'll let you know where it ends up and in what form as soon as I know.

If you find content on those legacy sites that you'd like to ensure we make available on OTN, please let me know.

The Fat Bloke Sings About VirtualBox

One of my favorite bike builders is Russell Mitchell, owner of Exile Cycles. He designed and his crew builds bikes like the Fat Bloke pictured above. You can buy the bike already built like the movie stars do, or initiate yourself into the world of old-school motorcycling by building it yourself from parts in Russell's shop.

Here's another Fat Bloke that's got something interesting to offer. Migrating from VMWare to VirtualBox with Oracle Enterprise Linux describes how to move a virtual machine from one virtualization platform to another. Kinda like moving your hard drive from one machine to another, as the Fat Bloke puts it. Or swapping out the engine on Exile's Brown Pearl and dropping it into the Hot Rod. Or, God-forbid, a Honda Gold Wing.

The writeup by Fat Bloke the blogger includes these topics:

  • Preparing to Migrate
  • Exporting the Virtual Machine
  • Importing into VirtualBox
  • Installing the VirtualBox Guest Additions
  • An Alternative Approach for Advanced Users
  • My favorite of Russell's bikes is the Silver Bullet, though the Brown Pearl is a close second.
