  • Profound Delivers First RPG Open Access ‘Handler’

    April 20, 2010 Alex Woodie

    Profound Logic, one of three ISVs committed to delivering “handler” solutions that enable i/OS shops to take advantage of the new Open Access for RPG technology IBM is shipping with i/OS version 7.1, tomorrow will begin delivery of the industry’s first handler solution with a new product called Profound UI.

    Now that Open Access for RPG is officially out of the bag, the System i community can begin discussing its merits. If the early comments are any indication, IBM has scored major points with anybody who is committed to writing business applications in RPG. Considering that RPG is by far the most popular 3GL on the i/OS platform, the boys in Rochester will be receiving kudos for months, if not years to come.

    One unequivocal supporter of RPG OA is Alex Roytman, the CEO of Profound. “This is perhaps one of the most important IBM i-related announcements in the last decade,” Roytman states in a press release. “It’s the exact type of functionality IBM i developers have been asking for. Finally, developers can use native RPG operations to talk directly to rich browser interfaces.”

    Roytman, who is one of the smartest RPG developers in the business, wasted no time in vaulting his company to the front of the pack with the delivery of Profound UI tomorrow, even before RPG OA becomes officially available with i/OS 7.1 on Friday. The company is holding a Webinar to mark the availability of Profound UI.

    As an RPG OA handler solution, Profound UI will take care of the nitty-gritty grunt work required to map an RPG application’s I/O into the constructs mandated by the Web’s architecture. Without a handler solution from Profound or another vendor–application modernization competitor looksoftware and ERP developer VAI so far are the only other two ISVs to commit to delivering handlers–RPG developers will face a very steep learning curve to develop their own handlers.

    The drag-and-drop screen designer in Profound UI allows people to create rich Web screens for RPG applications without training in HTML, JavaScript, or AJAX.

    Profound UI will bundle a drag-and-drop interface design tool that the company says will be simple enough for anybody to use. The design tool will ship with a collection of 150 pre-defined widgets, such as drop-down lists or a radio dial, which people can use to design their new Web browser interface for their RPG applications.

    According to Profound, the collection of widgets and their properties together will compose a native IBM i object called a Rich Display File. Rich Display Files are similar to traditional DDS display files (indeed, DDS plays a big role in the RPG OA scheme of things), and support standard RPG operations–such as execute format and write and read–just like traditional DDS display files served over 5250.

    The difference is data from the Rich Display Files are translated into standard Web formats through the Profound UI handler, thereby bypassing the need for 5250 while keeping the business logic in RPG and eliminating the need to use a proprietary API.

    “We are relying on the object-based architecture of the i here, and just like with green-screen apps, the integrity and reliability of programs is maintained through an object-based architecture,” Roytman writes in an e-mail. “Traditional green-screen apps use display files, and so does Profound UI. But Profound UI display files are Rich Display Files with metadata to represent rich user interface output rather than 5250 output.”

    The native support for “statefull” connections is one of the most important benefits that RPG OA will bring to System i shops that want to modernize their applications, according to Roytman. Getting that statefulness has always been a challenge given the constraints of the 5250 datastream and Web access techniques, such as CGI.

    “Without such a system, the developer has to do a lot of manual work to ensure relevant data is accessible as users navigate throughout the application,” Roytman writes in an e-mail. “For RPG developers, an ideal system is one that allows the typical ‘execute format’ (ExFmt) style of a top-down business application. And this is what Profound UI provides by tapping into RPG Open Access.”

    In addition to statefulness, Profound UI’s backend server will provide call stack support, error handling, subfile processing, session handling, overlays, library lists, “and virtually all other features that RPG programmers are already familiar with from traditional concepts,” Roytman says.

    Currently, Profound intends to support the most popular Web browsers, such as Internet Explorer, Firefox, Chrome, Safari, and Opera, as well as any mobile devices that support JavaScript, with the Profound UI handler. Development is moving fast right now, and the company already plans to unveil an update to Profound UI at the COMMON conference next month.

    Profound Logic is hosting a Webinar tomorrow, April 21, to introduce Profound UI. The Webinar, titled “It has arrived! A Native GUI for RPG,” starts at 1 p.m. EDT. For more product information or to register for the Webinar, visit the company’s Web site: www.profoundlogic.com.

    Integrate Virtual Tape to Automate Your Backups And Strengthen Your Ability To Recover From Cyber Attacks And Disasters

    With most IT departments stretched thin, finding something that can quickly free up IT time is definitely a bonus. That’s why it’s important to stop and take a look at integrating virtual tape into your backup and recovery. Virtual tape is one of those technologies where once you have it, you’ll wonder why you didn’t do it sooner. See a demo and get a $50 gift card.

    But what is it about using virtual tape that makes it so worthwhile? Why is it that so many IBM i shops are already using or considering using virtual tape for all or part of their backup and recovery systems?

    Virtual tape and virtual tape libraries offer a way to both simplify and strengthen backup and recovery operations. By incorporating virtual tape technology, automation of backups becomes possible resulting in hundreds of hours saved annually for IT departments and personnel.

    “We needed to find a replacement that would lower the maintenance cost and reduce complexity of our backup and recovery functions without a major disruption to our operations.” David Fray, Director of Enterprise Systems, ABC Financial

    LaserVault ViTL is a virtual tape and tape library solution developed specifically for use with IBM Power Systems (from AS/400 to iSeries to Power 9s). With ViTL you can:

    • Replace physical tape and tape libraries and eliminate associated delays
    • Automate backup operations, including the ability to purge or archive backups
    • Remotely manage your backups – no need to be onsite with your server
    • Save backups to a dedupe appliance and the cloud
    • Recover your data at lightspeed greatly improving your ability to recover from cyberattacks
    • And so much more

    Sign-up now to see a ViTL online demo and get a $50 Amazon e-gift card when the demo is complete as our way of saying thanks for your time. Plus when you sign-up you’ll receive a free facts comparison sheet on using virtual tape vs tape so you can compare the functionality for yourself.
