Three-fold Focus in Oracle Solaris Studio 12.3 Beta Program [24422]
Improvements in Performance, Reliability, Developer Productivity

In its beta release of Oracle Solaris Studio 12.3 the focus is on enhancements to performance, reliability and developer productivity, Oracle announces. In the area of accelerating performance, improvements, compiler and library optimizations for the newest Oracle Sun Enterprise Servers; acceleration of SPARC-based systems (incl. SPARC T4) that speed up application performance up to 3x over gcc, with up to a 40% boost over Sun Studio 12; and improvements in application performance of up to 1.5x over gcc and up to 20% faster than Sun Studio 12 for x-86-based systems figure prominently. Application observability has been improved by adding a new code analyzer that identifies common coding and memory access errors and by enabling application concurrency graphs and multi-process application profiling. Enhancements in the area of developer productivity include the capability of remote access from a Windows desktop in development of Oracle Solaris applications; the inclusion of Oracle Pro*C & OCI/OCCI Database development in Solaris Studio IDE; updated support for key open source runtime libraries, including BOOST and Apache C++; and the ability to build applications up to 20% faster than Studio 12.2 and up to 20% reduction in debug information size.

Java EE 6 Development with NetBeans 7 [24288]
New Title by David Heffelfinger from Packt Publishing

David Heffelfinger's new book from Packt Publishing, "Java EE 6 Development with NetBeans 7", wins the praises of Alexis Moussine-Pouchkine in his blog on The Aquarium. He writes that Heffelfinger has written a step-by-step book documenting " ... all of the Java EE 6 features and APIs (including CDI) using the IDE with the best Java EE out-of-the-box experience : NetBeans 7. It uses GlassFish as the default container and PrimeFaces as a JSF component suite." Packt announces that the ebook, available as both a PDF and ePub download, covers the latest versions of major Java EE APIs such as JSF 2.0, EJB 3.1, and JPA 2.0, and new additions to Java EE such as CDI and JAX-RS.

Oracle Secure Global Desktop Delivers Access to Development Environments [24218]
Oracle's Developers Worldwide Have the Access Required for their Work

As the Oracle white paper "Distributed Development Using Oracle Secure Global Desktop" explains, the Oracle Product Development IT Group (Oracle PDIT) employs Oracle Secure Global Desktop as a gateway to development environments used by Oracle’s software development teams working worldwide on Oracle Fusion, Oracle E-Business Suite, and various other Oracle applications. These software developers use Oracle Secure Global Desktop to access X Windows applications (xterm, fvwm, gnome) running on Solaris OS or Linux servers in the data center, giving them access to various graphical development tools such as Oracle JDeveloper, as well as systems running Microsoft Windows. Oracle PDIT has thousands of concurrent users spread across multiple Oracle Secure Global Desktop arrays around the globe. By this means, Oracle is able to provide its software development teams the access they require to their specific developer environments from any location, reliably and without performance degradation. In addition, administrators can centrally administer access to individual developer environments across multiple locations worldwide.

Oracle Tuxedo Delivers a New Way to Run PHP Applications [24190]
Download the VM from Oracle's Pre-Built Developer VMs Page

The Oracle Tuxedo Web Application Server Demo for PHP has been posted by the Oracle Tuxedo team. This free VirtualBox VM is available from the OTN Pre-Build Developer VMs page. The overview datasheet describes "Oracle Tuxedo ... [as] a service-oriented infrastructure for efficiently routing, dispatching, and managing requests, events, and application queues across system processes and application services." Oracle Tuxedo is said to provide a scalable and highly available mid-tier platform for managing and integrating heterogeneous applications. The VM uses Oracle Linux 5.6 and comes with PHP 5.3 and Oracle Tuxedo installed and configured. SALT and TSAM components of Tuxedo are available as well. Support for Tuxedo's PHP comes from a new mod_tuxedo module for Apache 2.2 (or Oracle HTTP Server), which handles all PHP scripts, using managed PHP processes to execute them and allowing existing applications to run normally. In addition, Tuxedo allows PHP to be exposed as a web service. Perhaps the greatest utility in Tuxedo 11/1/1/2 lies in its reported ability to make it easy to integrate modern solutions in a heterogeneous environment.

Keep Your DR Site in the Best Possible Condition [24175]
Use It for Application Development Testing

In the blog post "Leveraging a disaster recovery site for development -- Part 1" Amir Javanshir contends that this practice offers a testing cloud without additional costs for purchasing or deploying additional hardware while also giving access to the latest production data for testing, thus capturing the latest trends in using the application and making the DR site itself more secure. The last consideration is by no means the least, Javanshir writes, given that only when DR operations become necessary do shortcomings in the DR system itself. He says, " ... the best way to be sure that these systems are fully operational is to have them working / worked on, on a regular basis." In the forthcoming Part 2 the author promises details on how to use the Oracle Solaris Zones and ZFS technologies to setup such an architecture, at no extra cost.

Making Sense of Parallel Programming Terms [24181]
By Susan Morgan, Revised April 2011

This article explains common parallel and multithreading concepts, and differentiates between the hardware and software aspects of parallel processing. It briefly explains the hardware architectures that make parallel processing possible. The article describes several popular parallel programming models.

  • Parallel Processing
  • Parallelism in the Hardware
  • Parallelism by Software Programming Models
  • Shared Memory Programming Models
  • Distributed Memory Programming Models
  • Hybrid Programming Models
  • Oracle Parallel Application Development Software
  • For Shared Memory Systems
  • For Distributed Memory Systems
  • Hardware and Software for Cluster and Grid

It also makes connections between parallel processing concepts and related Oracle hardware and software offerings.
