Who are the real challengers in the payments space?


 o much of the UK’s traditional banking and payment infrastructure sits astride a very old and creaking rocking-horse. One that may look very nice in the corner of your living room, but chances are you’re a bit afraid it may no longer take your trim weight for more than a second or two.

UK Challenger Banks are taking a different route, and are leveraging EU Passporting to bring you & I better banking.  The names Atom, Revolt, Starling and Monzo are not necessarily high street names that you see every day, but the young and flexible millennials are adopting them in their droves.

The modern generation don’t really understand why anyone would want to go to a bank; in the same way we look back at the lost art of letter-writing, the clunky-ness of a fax machine, or the single-use capability of a waist-mounted pager. 

Banking and Payments are changing rapidly and variety of Alternate Payment Methods shows how much power has now transferred to the consumer. 

On the news this week was Barclays whose mobile App can now offer you the ability to control your spontaneous spending at certain merchants, like betting shops.  Wow, really?  Some of us have been offering this merchant control feature to our clients for years already. This and many other great features come ready-built inside the OmniPayments solution.

If you want to know how OmniPayments can help you engage with all these new payment methods, and offer flexibility to your customers contact or click here to read on.

Gravic Presents at BELUG, INNIG, and MATUG Events

This month we attended and presented on HPE Shadowbase at BELUG and INNIG (Brussels and Amsterdam), and MATUG (Baltimore).


During the European events, we enjoyed meeting with the customer base at the local HPE offices, and reviewing our latest feature and solution enhancements, along with discussing our future product direction. In particular, we discussed how best to manage the replacement of RDF (now in the ‘Mature’ product state) with HPE Shadowbase, and presented examples of how to do this using the low-risk HPE Shadowbase Zero Downtime Migration (ZDM) approach.


The attendees were also keenly interested in our latest HPE Shadowbase Compare enhancements, (including our new Repair feature), which allows both the source and the target databases to remain online for updating while the comparison takes place (it manages any ‘false positive’ mismatches due to replication latency). It also can be used to compare any two NonStop files or tables, regardless if they are being replicated or not (Enscribe or SQL). Since it works with any data replication engine environment, it can be used to validate and verify that the two databases match, and if not, will identify the discrepancies. The Repair feature is available when comparing NonStop SQL databases (MP or MX), and can be used to repair the discrepancies that are found.

We enjoyed connecting with everyone on a more personal level, along with sharing our various experiences and challenges. We appreciate the interest and feedback we received on our presentation, HPE Shadowbase Use Cases and Product Update. We hope the attendees enjoy their new Shadowbase socks! Special thanks to Ad Klijn, Bart Wever, and Ton Vrowe for coordinating the meetings, and for their hospitality while on site.


At MATUG, we also reminded the audience to consider migrating to HPE Shadowbase as their go-forward solution for the additional features it offers. We recapped a few slides from the TBC (Connect Technical Boot Camp) regarding the announcement of end-of-sales for specific J-series hardware platforms, and how HPE Shadowbase provides ZDM capabilities to assist customers in migrating to NonStop X with no risk and little to no application downtime (contact us for more information). We are grateful to John Vollers and Pat Boland for helping us plan and manage the MATUG meeting. We would also like to thank the other vendors that supported, attended, and presented, along with the consultants and customers that attended. Congratulations to Andrew Kim of Navy Federal Credit Union for winning our Beats earphones prize!

 ‘ITUGLIB team needs your input’


Sadly, your support team at ITUGLIB is at the point that our beloved NS 2000 (‘HPITUG’) is at the end of its support life.  We have been working with HPE to understand how they might be able to help, but it seems certain we won’t be able to solve the problem the same way we did nine years ago with a generous donation of hardware.  We are currently looking at all of our options, which include the possibility of a TNS-V solution.

 Because of this, and to continue to provide services you want and need, we’ve opened an Online Survey on Connect’s web site.  Since ITUGLIB is a service provided by members, for members, we want to know some key things such as what you depend on, how you access it, and what your future needs are.

 When you have a few minutes over the next couple of days, please go to and take the survey.  We estimate it should take less than 15 minutes of your time.

 We will be paying very close attention to the results of this survey to help us make sure that whatever choices we make, they’re done with our membership’s needs in mind.  Please take a few minutes to take the survey for us!



Green Screen, in 2018, seriously?



It's hard to say what is most surprising. To be sitting in the last throes of 2018, writing an article about green screen applications. Or to have recently found myself deep in the bowels of 3270 and 6530 terminal data streams writing code to automate the testing of them. More accurately, that should really read 'porting code' - since my firm, Ascert, has had a TAL screen handling and testing library since I first joined (and worked on it) back in 1997. Even then, I think most of us assumed it was the last chance saloon for a technology that would soon go the way of the dinosaurs, disco, and flares. But time and the future makes fools of us all I guess. Especially those whose predictions of the death of the mainframe have proved somewhere between premature and wildly inaccurate.

​At least the cause of this peculiar turn of events is simple to explain – a customer needed it. Rather less easy to explain is why this wasn't just one isolated customer, but a steady stream of requests from different sources over a period of months. Having barely had a single conversation over testing this style of application for the last 20 years, all of a sudden it was a hotter topic than contactless EMV testing, or Open Banking APIs. Being more of a practitioner than an analyst though, I parked my curiosity as to this resurgent interest and got on with the far more solvable task of understanding what was required and cracking on with delivering it. In so doing, I unwittingly uncovered some pieces that could help explain what was going on...

The first, and perhaps most unexpected piece, was that far from declining, according to at least one recent study mainframe use is actually growing again! It seems that the mass migration of applications away from mainframe data centers, that began with the client-server boom of the early 90s and continued through the cloud hosting and serverless computing trends, may have reached its zenith. Those applications, which could (arguably should) belong on cheap and widely available commodity infrastructure, have moved. Those which remain are too critical, risky, or expensive to consider migrating. Whether you consider IBM and HPE NonStop applications as classic, well engineered solutions built to last, or bygone relics that you are stuck with maintaining, the big iron systems we are left with today simply aren't going anywhere. There's no choice but to embrace the challenge of streamlining the management and testing of them within our modern, probably agile, practices.

Truthfully, I'd rather have avoided the word 'agile' for the entire article if it were possible – just mentioning it can be riskier than announcing you're a Red Sox fan before noticing you're in a Yankees bar. But as the second of those pieces I stumbled upon, there's no way around it. Fortunately we're going to stay on the firmest of ground, because in amongst Scrums, Sprints and the plethora of other ethereal terms, there is one whose value is beyond reproach: Continuous Integration, or CI for short.

Availability Digest Flips Pancakes

Jacob Goodman is a mathematician at the City College of New York. While folding towels for his wife one day, Goodman decided to restack the towels in the order of size, smallest towel on top. This wasn’t as easy as Goodman initially thought. He was forced to flip over a few towels at a time, reassess his progress, then flip over a few more until the towels were ordered to his satisfaction.

Goodman’s math-oriented brain led him to consider a curious problem. Was there a general formula that could calculate accurately the number of flips required to order any number of towels? Although towel flipping was one option, Goodman decided that the formula would be more interesting if it could be applied to pancakes. Thus was created the Pancake Problem, a deceptively difficult conundrum with some real world parallels to reordering disorganized data. Even Bill Gates was intrigued. His only academic paper is on the topic of pancake flipping.

“The Pancake Problem” is one of several articles in recent issues of the Availability Digest. In addition to this story, read the articles below as well as others.

Swapping Replication Engines with Zero Downtime Migration – Part 2 – In Part 1 of this article (October 2018 Availability Digest), we explained how an existing data replication engine can be replaced in a two-node scenario with a new version or with a different replication engine without requiring an outage. As we pointed out, it is important to avoid requiring different replication engines to communicate with each other. Interoperation between different versions is dangerous, error-prone, and can produce faults. Here in Part 2, we examine eliminating the versioning problem by using additional nodes. We also look at protecting the standby system while the replication engines are being switched.

Google Cloud Adds Dual Region Support – A challenge that companies face as they move data to the cloud is ensuring the data stays close to the application in order to reduce latency. Companies also require redundancy in the event of a catastrophic failure. Moreover, access to this data must be low latency. To address these requirements, Google has introduced a new dual-region storage option. Data is written to a single dual-region bucket, and Google automatically replicates this data to a backup bucket. In the event of a region failure, Google transparently handles the failover to the data in the backup bucket. Customers can pair specific Google dual regions, and data will be replicated automatically between these regions. The data is distributed redundantly across a multi-region that can span the U.S., the European Union, and/or Asia.

Object Storage – When Digest Managing Editor Bill Highleyman first began his career in Information Technology, dinosaurs roamed the earth; and data was stored in files. A file had a file name by which it was accessed. Each record in the file typically had a unique field that could be used as an index to access the record. Then came relational databases. These SQL databases allowed data items that had a relationship of some sort with each other to be stored together in the database, and they could be accessed based on that relationship. Now there is a new guy in town – objects. Object storage is a computer data storage architecture that manages data as objects as opposed to other storage architectures like file systems that manage data as a file hierarchy and block storage that manages data as blocks within sectors and tracks. In this article, we look at objects and how they are stored and retrieved.

The Availability Digest offers one-day and multi-day seminars on High Availability: Concepts and Practices. Seminars are given both onsite and online and are tailored to an organization’s specific needs. Popular seminars are devoted to achieving fast failover, the impact of redundancy on availability, basic availability concepts, and eliminating planned downtime.

The Digest provides a variety of technical writing, consulting, marketing, and seminar services. Individuals too busy to write articles themselves often hire us to ghostwrite. We also create white papers, case studies, technical manuals and specifications, RFPs, presentation slides, web content, press releases, advertisements, and so on.

LUSIS is a leading French software and IT services provider that launched more than 15 years ago.  The company is well known for offering advanced software solutions to the global retail payment industry for critical online transaction processing but it also provides FX brokerage platforms and other trading related services. After launching a dedicated Artificial Intelligence department, it has now started to create AI based trading strategies. We asked Fabrice Daniel Head of the AI team at the firm to tell us more about these and some of the other FinTech solutions it now offers.

​What range of FinTech products and services does Lusis offer for Capital Market applications?

Lusis offers a wide range of FinTech products and services for Capital Markets:

• FX trading; which is our core competence

• CFDs, Options Futures and Equities

• Advanced systems and tools including algorithmic trading, market making, backtest engine and trading strategy alerts sent to mobile applications

Our product is based on a microservice architecture providing high capacity, high availability and great flexibility. We are hardware and middleware independent with the ability to support cloud-based deployments.

​Lusis are experts in Artificial Intelligence and Machine Learning. How much impact do you expect these technologies to have in the FX trading environment?

We spent 5 years using data science approaches to analyzing and improving our trading platform. In June 2017 Lusis created a dedicated Artificial Intelligence department because we think AI will change end to end trading, automatic trading, portfolio management and it will impact everything that is related to Capital Market applications. We are especially focused on Deep Learning because of its incredible power and flexibility for problem resolutions.

Unlike the other Machine Learning approaches, for instance random forest, Deep Learning includes architecture as a concept. Today you are not just managing the number of neurons and layers of the model, and you don’t just select a feed forward, recurrent or convolutional model. Many approaches are now using more and more hybrid models mixing different types of Neural Networks to create more complex architectures with “building blocks” working together, each resolving a part of the problem.

You have developed solutions that use AI for the creation of trading strategies. How hard was that?

These allow the creation of models capable of discovering patterns by themselves in time series (market prices) to determine future moves. Doing this seems very straightforward and simple to do. However, there are many challenges in this task making it very difficult to achieve.

Tributary System: HPE OEM Tape Supplier

By Glenn Garrahan, Director HPE Business, Tributary Systems


NonStop professionals are well aware of Tributary Systems’ flagship product, Storage Director. This is an advanced, cost effective, secure software defined, policy-based and tiered enterprise backup virtualization solution. It enables data from any NonStop (or other) host, OS or backup application, to be backed up to any storage device, medium or technology, including on-premise and Public Cloud. In fact, Tributary Systems has entered into strategic partnerships with both IBM and Hitachi, allowing Storage Director to support both IBM Cloud Object Storage (ICOS) and Hitachi Content Platform (HCP).  Tributary Systems’ Storage Director is, to the best of our knowledge, the only solution that offers this connectivity to all NonStop NB, NS, and NonStopX servers.


 Along with developing Storage Director, TSI has been supplying HPE NonStop with Backup/Restore Solutions for over two decades, and today we are the exclusive OEM supplier of all Tape products and Library Management software.

There are currently three LTO 6 Tape drive types available for all NB, NS and NonStop X servers:

HPE M8801A/M8802A LTO 6 FC ACL

The M8801A and M8802A ACLs (Automated Cartridge Loaders) are capable of storing 24 LTO 6 cartridges. Each cartridge has a capacity of 6.25 TB (assuming 2.5 times compression), for a total unit capacity of approximately 150 TB.

HPE M8805A LTO 6 FC Tape Drive

The HPE M8805A LTO 6 represents HPE’s sixth-generation of LTO single play, manual load tape drive technology capable of storing up to 6.25TB per cartridge.

Remember that all LTO 6 drives are backward compatible; they can read and write to any LTO 5 cartridge and read-only any LTO 4 cartridge. These drives are ideal for use with NonStop X development servers; recall that tape is still the lowest cost per TB storage media. Looking on the web, one can find HPE LTO 6 cartridges priced as low as $22.58 for 6.25 TB, or only $3.60 per TB.

So contact your HPE Sales Rep to order an LTO 6 drive, and you can get additional information at:
