Oracle Academy, Computer Science Teachers Association Team Up
Plan Sessions for Hundreds of U.S. and Canadian Computer Science Teachers
The Oracle Academy is collaborating with the Computer Science Teachers Association (CSTA) to instruct teachers in the U.S. and Canada in the delivery of the Oracle Academy’s Introduction to Computer Science curriculum. The curriculum includes Database Design and Programming courses and a Java-specific curriculum aligned to Oracle certification and the US Advanced Placement Computer Science A exam. The Oracle Academy and CSTA will host 32 teacher training events and workshops in the training of up to 600 teachers throughout Canada and the U.S. in sessions running from February through August 2013.

'Time for Change: Optimizing Datacenter Infrastructure with Technology Refresh': IDC Whitepaper
Survey Reveals Positive ROI, Payback, Productivity Results
The authors of the IDC white paper "Time for Change: Optimizing Datacenter Infrastructure with Technology Refresh," Randy Perry and Susan G. Middleton, identified the benefits from a survey of seven enterprises that had recently undergone a refresh of their Unix server storage and operating environment. The survey focused as a secondary issue on the results of partnering with Oracle to support their respective consolidation efforts. The datacenter refreshes provided a three-year ROI of 267% and a payback in less than 13 months. One overriding principle the authors derived from their survey is that recent experience with IT infrastructure does not project linearly into the near future.

Oracle Delivers Unique Value with Oracle Solaris: IDC White Paper
IDC Takes a Second Look at Oracle Solaris and Customer Attitude
In his comments on the revised IDC white paper "Oracle Delivers Unique Value with Oracle Solaris" Larry Wake remarks on its highlighting of how Oracle Solaris 11 is optimized for cloud computing, with unique virtualization, scaling, and provisioning capabilities, evidence, Wake notes, of Oracle's increased investment in Solaris since the Sun acquisition. White paper co-authors Gary Chen and Al Gillen include a case study based on the experience of Synodex, a medical records processing company that adopted Solaris 11 early. The white paper also notes a revitalized level of customer confidence in Oracle Solaris since 2010 vis-a-vis competitive major Unix solutions.

Oracle IaaS with Capacity on Demand Enables Users to Pay for Capacity as Needed
Engineered Systems Hardware Deployed On-premise for a Monthly Fee
Oracle's portfolio of cloud products continues to grow. The latest addition is Oracle Infrastructure as a Service with Capacity on Demand (Oracle IaaS). Oracle’s newest private cloud offering enables organizations to deploy Oracle Engineered Systems, including Oracle Exadata Database Machine, Oracle Exalogic Elastic Cloud, Oracle Exalytics In-Memory Machine, Sun ZFS Storage Appliance, and Oracle SPARC SuperCluster, in their own data centers for a monthly fee. Instead of buying or leasing the hardware, and without making an upfront capital expenditure, customers can deploy on-premise, spreading the cost over time by paying a simple monthly fee, adding or shedding additional capacity as required.

Big Data Appliance X3-2 Updates
Review of Changes in Hardware and Software
The release of Big Data Appliance X3-2 includes improvements in both the hardware and in the software, reports Jean-Pierre Dijcks. The new 2 x 8-core count CPU (as compared to the earlier 2 x 6-core CPU) results in more parallel compute power while saving some 30% in energy and heat. Changes in the software include CDH 4.1.2 and the default set up of highly available name nodes for Hadoop, the Oracle Enterprise Manager management of the BDA, the uptake of the Oracle R Distribution and the updates to Oracle NoSQL Database, as well as numerous bug fixes.
Evaluating and Comparing Oracle Database Appliance Performance
White Paper Reports Performance on OLTP- and DSS-type Workloads
"Evaluating and Comparing Oracle Database Appliance Performance," an Oracle white paper, documents the performance testing on OLTP- and DSS-like workloads executing of Oracle Database Appliance. During the performance testing Oracle Database Appliance demonstrated scalable performance for both workloads. Using all 24 cores, Oracle Database Appliance supported 10,000 concurrent Swingbench users and more than 9800 Swingbench transactions per second while maintaining an average response time of less than 30ms. With the DSS type workload, Oracle Database Appliance easily supported a sustained IO throughput of more than 2400 MB/Second. Some configuration adjustments and tuning were needed to obtain maximum performance from the Oracle Database Appliance.

Rick Hetherington on the SPARC T5
Plus 'SPARC T5: 16-core CMT Processor with Glueless 1-Hop Scaling to 8-Sockets': Hot Chips Presentation
Rick Hetherington delivers an overview of the SPARC T5 processor, explaining how doubling the number of S3 cores allows the T5 to achieve 2X throughput improvements, and how 28 nanometer silicon enables clock speed increases to 3.66 Gigaherz (GHz). Hetherington adds that on-die PCI Express Rev 3 results in a doubling of I/O bandwidth. Scaling the SPARC T5 to eight sockets and 16 cores gives the processor the capability of gluelessly interconnecting eight sockets for a total of 128 cores, each supporting up to eight independent threads totaling 1024 CPUs. An accompanying Hot Chips presentation provides a detailed look at the SPARC T5.

    Oracle VM for SPARC: Best Practices - Top Ten Tuning Tips
    Jeff Savit Offers Both Tips and Cautions
    While there are relatively few "tuning knobs" to adjust with Oracle VM Server for SPARC, there are nevertheless several best practices that can enhance or ensure performance. Jeff Savit's post includes 10 of these, along with several cautions about the use of best practices themselves. He advises users to be aware that best practices do not apply in every situation and that they undergo changes as technology changes. Also, once service level objectives have been met, it's best to quit tuning and move on to something else. Finally, the application of any best practice calls for a healthy measure of judgment.
    Examining Oracle Solaris 10 1/13 Secure Copy Performance for High Latency Networks
    Findings Reveal Significantly Improved Performance
    With Oracle Solaris 10 1/13, the performance of secure copy or scp is significantly improved for high latency networks Brian posts. Oracle Solaris 10 1/13 enabling a TCP receive window size up to 1 MB has up to 8 times faster transfer times over the latency range 50 - 200 msec compared to the previous Oracle Solaris 10 8/11, he writes, adding that the default TCP receive window size of 48 KB delivered similar performance in both Oracle Solaris 10 1/13 and Oracle Solaris 10 8/11. Settings above 1 MB for the TCP receive window size delivered similar performance to the 1 MB results.

    Network Virtualization and Network Resource Management
    Part 5 of Virtualization Series by Detlef Drewanz
    Detlef Drewanz has posted part 5 of his series on virtualization, defining and discussing the features of internal and external network virtualization and network resource management in this segment. Drewanz explains the features that are part of virtualization products, calling them the "glue" that binds all the VMs, zones, and containers together and enables them to communicate among themselves and with the outside world. He then recommends the employment of several types of network resource management tools, including constraints, scheduling, and partitioning.

    JavaFX Open Source: A Progress Report
    Plans Are to Include Android and iOS Implementations as Well
    The open sourcing of JavaFX is the subject of a progress report by Richard Bair, who shares a list of projects that have been moved to open source, along with news about what to expect by way of the actual completion of the undertaking. Bair also shares the news that the Android and iOS implementations will also be open sourced, even as he addresses Apple's antipathy toward GPL-licensed applications in its app store. He suggests a workaround to use until such time as Apple changes its mind about the GPL-licensed app, which is to use JavaFX on iOS via OpenJDK / OpenJFX.
