SysAdmin and Systems Developer Newsletter, January 2016
Congratulations to Systems’ Newest Oracle ACE Director:
Johan, whom hails from the Netherlands, is a Oracle Linux, scripting, and open source guru working for Capgemini. He has worked as a developer, administrator, manager, project manager, managing consultant and senior architect within several IT companies and IT departments and specializes in Oracle technology, infrastructure technology, and IT strategy and has been advising and actively working with a large range of customers and companies.
Join the OTN VTS Systems Replay Library Group and hear from Oracle ACEs and Oracle Product Experts, as they share their insights and expertise through hands–on–labs, highly technical presentations, and demos that enable you to master the skills you need to meet today’s IT challenges.
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...
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.
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.
Oracle VM VirtualBox 5.0.12— Oracle has released VirtualBox 5.0 Maintenance Release 12! This release is a major improvement which include a large number of changes and bug fixes.
Oracle Linux 7.2— We’re happy to announce the general availability of Oracle Linux 7 Update 2, the second update release for Oracle Linux 7. You can find the individual RPM packages on the Unbreakable Linux Network (ULN) and the Oracle Linux Yum Server and ISO installation images are available for download from the Oracle Software Delivery Cloud.
Oracle Solaris 11.3— Includes Full Support for Security in Silicon, SQL in Silicon, Secure Live Migration, Secure Lifecycle Management, Automated Upgrades and Rollbacks, and High Availability for OpenStack. To read more, please read the official press release.
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.
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.
