I have been thinking a lot about “Social Business” lately and wanted to write up some of my thoughts on the subject. There is certainly no shortage of information on the topic out there and why it's so great, but actually applying that to our little part of the universe is a different story. Much of the literature that I read about on the subject have statements like “social businesses make 57% more profits” and “employees at social businesses are 92% more engaged.” What I struggle to ever find is...

Global airline travel is estimated to reach 3.6 billion passengers by 2016 according to the International Air Transport Association. That is a lot of peanuts and seatback transgressions. But something I find amazing as I hear this statistic is how the majority of airline travel, including this predicted increase, has successfully and reliably depended on a singular solution from IBM for almost 50 years! 75% of all airline travel relies on IBM Transaction Processing Facility for their business-critical operations. These... [More]
Many of our clients who rely heavily on z/TPF as a crucial part of their transaction infrastructure also face the challenge of increasing manpower to enhance and grow their critical systems. The TPF Lab and our clients can already claim a valuable, and proficient systems and applications software engineering staff. However, perhaps your project managers are often faced with more work that needs to be done than people they can assign to do that work. Many of us were recruited to work with TPF right out of college. But... [More]
The z/TPF and z/TPFDF PUT 11 eDelivery packages are now available. The downloads can be accessed through the z/TPF 1.1 & z/TPFDF 1.1 tab on the TPF Family Products: Product Software web page. Please see Service Bulletin 182 for details.
Watch and then share this blog entry and short video with your non-TPF colleagues to give them a better idea of what z/TPF is and what it can do. https://ibm.biz/zTPFvideo The video includes comments from Jim McCarthy (SVP at Visa), Martin Kennedy (Director at Citigroup), Gordon Wilson (CEO at TravelPort), and Michael Perera (VP at IBM). Visa's global credit card authorization, Citigroup's North American ATM system and TravelPort's Travel Commerce Platform all run on z/TPF. z/TPF is the foundation for the many of the... [More]
Having worked for IBM nearly 27 years, almost exclusively in the z/TPF development lab, I have had the privilege of working with a wide range of people. From those who remember the early days of ACP (our predecessor), to university students born well after my career began. By starting my career in the middle of TPF's evolution, I have grown to appreciate our long history, from the first SABRE system, to the new developments occurring every day, to our exciting future. Why bring this up in a public BLOG? Even though I am closer to the... [More]
I still recall the first time I saw someone go through the airport security line with their electronic boarding pass. There I was, with my shoes in hand, my computer bag already unzipped for easy laptop removal and my boarding pass and license in my left…or was it my right, pants pocket. The teenager in front of me of course thought the announcement indicating everyone be ready for your turn at the front of the line did not apply to him, as he stood there checking his text messages on his phone instead of having his papers in...

Citi's Managing Director of Core Infrastructure Services, Anthony DiSanto spoke at the IBM Mainframe50 event in New York City on April 8 and shared his insight into the partnership with IBM that has sustained their Enterprise Computing Center for the past 50 years. Hear Mr. DiSanto's perspective on how listening is critical to any relationship and how that translates into the daily operations at Citi, one of the world's largest Financial... [More]
By Barry Goldberg & William Lappan With enhanced format-1 globals support, the I-stream unique primary and extended global areas are relocated to system virtual memory (SVM) above 2 GB to alleviate memory constraints below 2 GB. Only the main I-stream is allocated below 2 GB. Previously, all format-1 global areas used SVM below 2 GB, which limited the number of I-streams that you could add to the z/TPF system. After you enable enhanced format-1 globals support, each application I-stream uses the same virtual addresses below 2 GB as the main... [More]
z/TPF customers have expressed interest in exchanging messages with Linux systems. One common question that has been coming up is whether to use distributed (x86-based) Linux, or Linux on z in an LPAR next to the z/TPF LPAR. One factor important to many customers is latency so analysis was done to understand the network latency between these two configurations. The testing was done on an zEC12 machine comparing the latency from a z/TPF LPAR to a Linux on z LPAR in the same zEC12 machine sharing an OSA card to the latency from... [More]
After loading PUT 11 to your favorite TPF test system, you may notice some new behaviors in the Variables view and the Remote System Explorer(RSE) in TPF Toolkit. For PUT 11, I delivered four enhancements to the z/TPF debugger that I hope improve your debugging experience. Active USING statements are displayed in the Variables view When debugging assembler code, any active USING statements will be listed in the Variables view and will allow easier access to the content of the labeled DSECT. The debug information for the active module is queried... [More]
