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.

Make Your Database Run Faster on Oracle Linux

If you can get your hands on a Sun Flash Accelerator F40 PCIe Card, and you're running Oracle Database 11g Release 2 or later on Oracle Linux, you can use the Oracle Database Smart Flash Cache to improve performance and response times. That was a mouthful, so let me say it again.

  1. Configure Sun Flash Accelerator F40 PCIe Card as a file system.
  2. Configure Oracle Automatic Storage Management, a feature of Oracle Database, to use multiple Sun Flash Accelerator F40 PCIe Cards.
  3. Configure the Database Smart Flash Cache capability of Oracle Database.

Your pals at Jay Leno's garage can keep a 27-liter 1930 Bentley humming, but they can't help you with that little procedure can they? No worries, Rick Stenho may not own a Bentley, but he can help your database run faster.

Tech Article: How to Improve Database Performance Using Database Smart Flash Cache on Oracle Linux

by Rick Stenho

Oracle Database 11g Release 2 Enterprise Edition allows you to use flash devices to increase the effective size of the Oracle Database buffer cache (Level 2 cache) without adding more main memory. This capability is referred to as Database Smart Flash Cache. This article walks you through the steps required to take advantage of it.

Caution: Any performance advantages you obtain with smart flash cache will probably be nullified by the time you waste watching Jay Leno's garage.

Simplifying the Installation of Oracle Database on Oracle Linux - Reprint








Most of my workdays start by shapechanging me into a seven-headed Hydra, and each Hydra promptly makes a beeline for multi-tasking hell. So, when I get a chance to simplify something, anything, I jump on it.

Ginny has done that for OTN at last twice. Below are two of her exercises in simplifying our lives. We published these articles before, but we recently had to rebuild one of them because somebody (I'm not going to say who) deleted it. To avoid annoying one of your Hydras, and instead send you off to a peaceful weekend, here they are again.









How I Simplified Oracle Database Installation on Oracle Linux 5

by Ginny Henningsen

Before installing Oracle Database 10g or 11g on a system, you need to preconfigure the operating environment since the database requires certain software packages, package versions, and tweaks to kernel parameters. Ginny discovered that Oracle Linux provides a remarkably easy way to address these installation prerequisites. Find out how.

How I Simplified Oracle Database 11g and 12c Installation on Oracle Linux 6

by Ginny Henningsen

Similar to the article above, but updated for 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.

The Case for Running Oracle Database 12c on Oracle Solaris

You may have already seen some of these individually, but here are several resources that explain why Oracle Database 12c runs so well on Oracle Solaris and SPARC.

Oracle Solaris 11 + SPARC

Interviews with experts, videos, architectural papers, technical articles, and other resources to help you understand the optimizations between the OS and hardware layers that make Oracle Solaris and SPARC such a winning combination. link

Oracle Solaris 11 + Oracle Database 12c

A deeper dive into the optimizations and capabilities of Oracle Solaris that make it such a good platform for Oracle database 12c. link

Oracle Solaris 11 + Oracle Stack

A high-level overview of the optimizations in Oracle Solaris 11 that make it an excellent platform for the entire Oracle stack. link

Article: How Oracle Solaris 11 Makes Oracle Database So Fast

A technical explanation of the optimizations that make Oracle Database run so fast on Oracle Solaris 11. Memory, critical threads, kernel acceleration, virtualization and resource management, and much more. By Ginny Henningsen. link

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.”

It's on Wednesday, July 10, 2013 at 9 a.m. PT / 12 p.m. ET. link .

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.

Video Interview: Why Is The OS Still Relevant?

In a world of increasing virtualization and growing interest in cloud services, why is the OS still relevant? Michael Palmeter, senior director of Oracle Solaris, explains why it's not only relevant, but essential for data centers that care about performance.

Interview: An Engineer's Perspective: Why the OS Is Still Relevant

Sysadmins are handling hundreds or perhaps thousands of VM's. What is it about Solaris that makes it such a good platform for managing those VM's? Liane Praza, senior engineer in the Solaris core engineering group provides an engineer's perspective.

Interview in the Lab: How to Get the Performance Promised by Oracle's T5 SPARC Chips

If you want your applications to run on the new SPARC T5/M5 chips, how do you make sure they use all that new performance? Don Kretsch, Senior Director of Engineering, explains.

Interview: Why Oracle Database Engineering Uses Oracle Solaris Studio

The design priorities for Oracle Solaris Studio are performance, observability, and productivity. Why this is good for ISV's and developers, and why it's so important to the Oracle database engineering team. Taped in Oct 2012.

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.
