Oravle Virtual Assembly Builder, New Database Assemblies Ease Application Deployment to the Cloud
Applications Can Be Stored, Deployed from Enterprise Manager 12c Self-Service Interface
Oracle Virtual Assembly Builder (OVAB) used in conjunction with Oracle Enterprise Manager 12c can graphically model the topology of applications deployed to the cloud, define all dependencies and deployment constraints, and package the entire application as an application assembly that can be uploaded to the centralized software library in Enterprise Manager for self-service deployments, according to Anand Akela. Oracle Enterprise Manager 12c now also has a link to Oracle that will announce the availability of new downloadable assemblies. Customers can create a zone of Oracle VM 3.x servers and deploy these assemblies from the Enterprise Manager 12c Self-Service interface.

Oracle Makes Enterprise Manager Ops Center 12c Free for Existing Customers
Engineered to Make the Most of Oracle Solaris 11
The newest version of Oracle Enterprise Manager Ops Center, is available free for any organization with an Oracle Premier Support agreement under an initiative called the Ops Center Everywhere Program, writes Joab Jackson in IT World. Oracle Enterprise Manager Ops Center 12c includes several updated capabilities for managing Oracle Solaris 11, specifically, the ability to use Solaris Image Packaging System (IPS), Automated Installer (AI) and Alternate Boot Environments across multiple servers, and is also the first version to allow administrators to manage both x86- and Oracle SPARC-based servers from a single console--the first commercial product with this capability, Oracle says.

Bring KVM to illumos
An Account of the Effort by Brian Cantrill
An interesting account of how KVM came to be part of illumos is available in a post by Brian Cantrill, who credits the efforts of his collaborators Max Bruning and Robert Mustacchi in "porting" the Linux kernel virtual machine (KVM) to the SmartOS. The account covers the many weeks between Bruning's initial copying of KVM bits from the stable Linux 2.6.34 source to the trio's successful booting into KMDB running on a SmartOS.
DTrace

Summary of the Program at dtrace.conf(12)
Includes Videos of Important Segments
There is a convenient summary of the events at dtrace.conf(12) in a post by Adam Leventhal. The post is divided into several sections, including:

  • User-land CTF and Dynamic Translators
  • The D Language
  • Work with DTrace
  • DTrace with Oracle Enterprise Linux
  • A ZFS DTrace Provider
  • Whither DTrace

Leventhal includes links to videos dealing with the conference, one of which is Kris van Hees's presentation on the Oracle port to Linux and Eric Schrock on the D language additions in this release.

DTrace Now Available for Oracle Linux
View DTrace Team Appearance at dtrace.conf On-demand
DTrace is now available for Oracle Linux on the Unbreakable Linux Network, Lenz Grimmer posts. He reports the packages are based on the final public release of the Unbreakable Enterprise Kernel Release 2 (2.6.39). There is no new functionality specific to DTrace in this release. Users find that libdtrace is now a shared library although, Grimmer cautions, the API/ABI is not fully stabilized and may be changed. Also, QA testing has resulted in the reorganization of some test cases into their own subdirectories, which enables using the test suite in a more fine-grained manner.

Benchmarking MySQL Replication with Multi-Threaded Slaves
Multi-Threaded Slaves Delivers 5x Higher Replication Performance when Configured with 10 Databases/schemas
In his post "Benchmarking MySQL Replication with Multi-threaded Slaves" Mat Keep measures performance improvements achieved when enabling the Multi-Threaded Slave enhancement feature of MySQL 5.6. His apparatus included two Linux servers, one running the replication master, the other running the replication slave. Multi-threaded slaves deliver ~5x higher replication performance when configured with 10 worker threads, with the load evenly distributed across the 10 x schemas. The configuration does not scale noticeably from 5 to 9 worker threads, but, configured with 10 worker threads, scalability increases significantly, suggesting it is desirable to configure the same number of worker threads as schemas.

EOL Comes for Linux 2.4
Release Makes It to 11
The news, as reported by Sean Michael Kerner in InternetNews.com is that the end has come after 11 years for Linux 2.4. He writes that the 2.4 kernel has been in maintenance-only mode for the most part for the last six years, ever since the 2.6 kernel was first released. There has long been a subset of vendors that still relied on 2.4, but that's no longer the case, he notes. Although EOL has been officially declared, Kerner avers that, as is often the case in open source, "I suspect this isn't quite the last we've heard of Linux 2.4."

Using Throughput Latency 'Gaps' to Optimize Performance
'How the SPARC T4 Processor Optimizes Throughput Capacity': Oracle Technical White Paper
"How the SPARC T4 Processor Optimizes Throughput Capacity: A Case Study," an Oracle technical white paper by Ruud van der Pas and Jared Smolens, examines the architected latency-hiding features of Oracle's UltraSPARC T2+ and SPARC T4 processors, focusing on instruction-level latencies. In instances where neither caching nor prefetching work, the latency-caused "gaps" in a processor's execution pipeline can be employed to execute instructions from another application or a different thread from the same application. The latency hiding engineered into Oracle's SPARC T-series processors has this capability, and van der Pas and Smolens illustrate how this works at the application level.

Traffic on Oracle's SPARC Roadmap Is Accelerating
Achievements Outpace Initial Projections
"The driving time to major SPARC milestones has gotten shorter, and with the recent release of the SPARC T4 chip, Oracle is providing better-than-promised performance," writes David A. Kelly in Oracle Magazine Online. One typical company, attracted by the performance the SPARC processor delivers, is Tucson Electric Power Company, whose Senior Systems Administrator, IT Operations Group, Scott Myers, says, “We went from using more than 20 servers and a bunch of different operating systems to having everything running on Oracle Solaris 10 inside Oracle Solaris Zones. Oracle Solaris Zones allow us to consolidate more operations on a single server .... ”

    Solving Storage Problems Caused by Server and Desktop Virtualization
    Hardware-based Replication Is not the Answer

    There are alternatives to using direct-attached storage (DAS) to remedy the storage problems inherent in server and desktop virtualization, argues Jon Toigo, president of Toigo Partners International: hardware-based replication is not the solution, he contends; VMware, on the other hand, may just be the answer. Toigo recommends storage virtualization (putting capacity management, performance management, data protection management into a virtual pool and then create pools of storage that move with the guest machine. Users can create an atomic infrastructure based on building blocks of storage that grow and scale as storage is added to it.

    Speculations on the Performance Impact of Zones
    Joerg Moellenkamp Looks at the Benchmarks

    "What is the overhead of using Zones," ponders Joerg Moellenkamp in a recent post. He admits to never having measured any overhead caused by zones but he also contends that additional load introduced by processes wouldn't be there when only one zone is in use but, when additional monitoring daemons -- like additional daemons having a controlling or supervising job for the application that resulted in slightly longer runtimes of processes -- questions of overhead become pertinent. Moellenkamp posts links to a number of benchmarks that provide some evidence of the effect of overhead imposed by the use of zones.
