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

The Oracle Tuxedo 11.1.1.2 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 11.1.1.2 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.

JDK 7 Support in NetBeans IDE 7.0: A Quick Overview [24041]
Tutorial Shows How NetBeans Can Help in Writing Code Compatible with JDK 7 Language Spec

One of the most valuable features of NetBeans IDE 7.0 is its ability to automatically fix syntax, which it does -- along with much more -- when users enable support for such JDK 7 language features as diamond operator, string in switch, and multicatch. With these features enabled, NetBeans 7.0 can assist users to write code that is compatible with the JDK 7 language specification. In the blog from NetBeans.org entitled "JDK 7 Support in NetBeans IDE 7.0: A Quick Overview" readers will find a tutorial that shows step-by-step how to enable JDK 7 support in the IDE and illustrates how the IDE handles new language constructs.
