FEATURED TECHIE CONTENT
 
by Antonis Tsavdaris
This article describes how to build a Cassandra single–rack database cluster on Oracle Solaris 11.3 and extend its overall availability with LUN mirroring and IP network multipathing.
This blog introduces the series on Oracle VM tuning and gave a perspective on virtual machine performance.
This blog on Oracle VM performance reviews general performance principles, and follows with a review of Oracle VM architectural features that affect performance. This will be high-level as a basis for more technical detail in subsequent articles.
The first articles in this series discussed general topics in virtual machine performance, and gave a brief architectural overview for Oracle VM Server for x86 and Oracle VM Server for SPARC. In this article we'll discuss performance goals for virtual machine environments, especially in the cloud, and some things that are different in the virtual world from the bare-metal world.
The previous article in this series described goals for virtual machines in the cloud, and CPU and memory recommendations to help achieve them. This article will go into more detail for Oracle VM Server for x86 CPU and memory management...
The previous article in this series described Oracle VM Server for x86 CPU and memory management. This article discusses domain types, huge pages, and how to configure scheduling.
This article focuses on what is often the most important performance topic: I/O. Most commercial applications, that is, everything except technical computing, depends more on I/O than anything else – but it doesn't always get the coverage it deserves. Seriously: people obsess about CPU scheduling and overcommittment, but most performance problems (IMHO) are I/O. We’ll discuss network I/O (briefly, for a reason you'll see in a moment), and disk I/O.
COMMUNITY UPDATE
 
“OTN Garage” is now called “OTN Systems Hub” — As we mentioned a few months ago, the OTN Garage name will be changing to OTN Systems Hub. This is an effort to make the community social channels name be a little bit more easily recognizable to newcomers, and help them understand the contents of the community. [Click here to read more]
NEW COMMUNITY SPACE: NETWORKING — As you may have noticed, there was an absence of a “Networking” space to house discussion spaces and informational content. So, I made one! It has discussion spaces for General Discussion, Solaris Networking (already exists, but is now brought under the "Networking" space), and Linux Networking. It also has informational spaces for Ethernet, InfiniBand, and Virtual Networking where we will post the latest OTN content for those product lines; such as white papers, how to instructional articles, specs and configuration support documents, and blogs from the teams.

Hardware Matters When You Encrypt Your Database | Erik Benner — If you don't want your boss to yell at you, take two minutes to watch this tech tip from Oracle ACE Erik Benner, in which he explains how to avoid database performance issues that can result from encryption.
What's New in Oracle Solaris 11.3 — Oracle Solaris 11 is a complete and secure cloud platform. With best of breed technologies for computer, networking and storage, learn how Oracle Solaris can help transform your IT operations to move to the cloud and make it simple to do. In this session we will cover some of the latest innovations engineered in Oracle Solaris 11.3 to manage a secure and integrated, large-scale cloud environment.
Automate Your Oracle Solaris 11 and Linux Deployments with Puppet — Puppet is a popular open source configuration management tool that is used by many organizations to automate the setup and configuration of servers and virtual machines. Solaris 11.2 includes native support for puppet and extends the resources that can be managed to Solaris specific things like zones and ZFS. This presentation will give system administrators that are new to puppet an introduction and a way to get started with automating the configuration of Oracle Linux and Oracle Solaris systems, talk about how puppet integrates with version control and other projects and look at the Solaris specific resource types.
Best Practices Building Efficient and Secure Cloud Infrastructure — Learn how to create virtual machines(VMs), deploy VM’s using Templates, rapidly migrate those VM’s to the Cloud, and deploy Oracle Applications and Databases in minutes on a flexible, secure, Private Cloud Infrastructure. Additionally, experience Oracle's Enterprise Cloud Infrastructure with Oracle's Enterprise Manager-Cloud Control to automatically provision both Operating Systems and Oracle Databases in a DBaaS model.
How To Increase Application Security & Reliability with Software in Silicon Technology — Learn about Software in Silicon Application Data Integrity (ADI) and how you can use this revolutionary technology to catch memory access errors in production code. Also explore key features for developers that make it easy and simple to create secure and reliable high performance applications.
Designing a Multi-Layered Security Strategy — Security is a concern of every IT manager and it is clear that perimeter defense, trying to keep hackers out of your network, is not enough. At some point someone with bad intentions will penetrate your network and to prevent significant damage it is necessary to make sure there are multiple layers of defense. Hear about Oracle’s defense in depth for data centers including some new and unique security features built into the new SPARC M7 processor.
Eliminate Cloud Security Threats with Oracle Systems — Learn and understand about the security threats to your public and private cloud and gain insight into how the Oracle Security Architecture helps reduce risk. This webcast will provide detailed information on the top 20 cloud security threats and how different parts of the Oracle systems stack help eliminate each threat.
