New Reflex UI: LightWave ServerTM Advantages – The Simple Way

Insider Technologies recently went through a significant technology refresh of one of our core products, Reflex.  This article explains the reasoning behind that refresh, the steps that we went through to develop the refreshed solution, and the benefits we are enjoying as a result of the updates.

We hope that it will be of interest to Connection readers, as, while we are a software development company, in this case we have also been a user of a middleware solution used to modernize our application. This is a situation that is not unique for us – indeed many NonStop users find themselves with similar requirements.



Reflex is an Operations and Service Management Facility for your entire HPE NonStop arena. The package provides performance metrics and log monitoring for all NonStop subsystems, OS and application components. Nominated error conditions may be automatically corrected and/or transferred to the Reflex graphical alerting views, graphical event Console, Enterprise Management, mobile GSM or email technologies.

It is successfully utilised in the UK’s major banks, monitoring their NonStop system health and applications such as payments, foreign exchange, MQ 8.



Compared to other UIs, the original Reflex Client looked quite outdated.

Since the above UI was built on the Microsoft Foundation Class (MFC) framework, which included the use of outdated IDE software, development and maintenance became increasingly difficult.

Reflex also utilises an in-house communications product called ‘Fastpipe’ to execute multiple TCP/IP socket sessions between the Client and the NonStop Serverclasses; this has become increasingly difficult to manage and requires expert knowledge to maintain its development.


Client-Server Communication

Over time, FastPIpe had been improved to support other operating systems such as Linux, as well as updates to the Windows OS.


Sometimes, these changes would include additional modifications to both the Client and the NonStop object code, both of which would increase the development time and therefore further complicate the software maintenance.

Because of these issues, we soon realised, that along with the need to create a new usable UI, we would need to find a more efficient and effective framework for communication between the Client and the NonStop serverclasses.

It was determined that using a REST API to retrieve data from the NonStop would be the best way to do this.


NuWave LightWave ServerTM

We were aware of LightWave ServerTM , offered by NuWave Technologies, and an analysis of their product suggested that this was the best option for our requirements. Therefore, we utilised a trial copy of LightWave ServerTM to proceed through a Proof of Concept (POC) exercise. Within a very short time, we quickly realised that LightWave ServerTM would satisfy all our requirements.

This has also helped us to design and build a completely new look for the Reflex Client and in comparison with our old UI, our development time has shortened considerably, helping to bring a new UI very quickly to market.


Immediate Benefits

The LightWave ServerTM Console which we use to control and administer LightWave ServerTM, makes setting up of the REST APIs incredibly easy.

The Console opens DDL definitions directly from the NonStop and enables us to build REST/JSON definitions from those DDLs. A service is simply created by pointing to a backend application, such as a Pathway Server and once in place, it’s ready for development.

For us, this whole process required very little time and as the Web allowed us to check the API before writing any code, we could make sure that the correct data was returned from the NonStop; a function that can now be done by either a Windows developer or a NonStop developer.

With the ease of use and reliability of NuWave’s LightWave ServerTM, it helped us to then concentrate on a new look and feel for the Reflex UI.


New Reflex UI Examples:

  • Network Monitor
    • Multiple NonStop systems monitored from a single UI
  • Status Monitor
    • Alert views for all subsystems, e.g. disk, CPU, tape, TMF, SQL, files, processes, applications, MQ 8
  • Dashboard
    • Real-time performance metrics, e.g. disks, CPUs, files, processes, subvolumes, IPUs, heap

Additional Benefits

Prior to utilising LightWave ServerTM, the development of our pre-LightWave UI required regular investigations to determine why the IPM was not handling and correctly filling in the request, or coding the conversions correctly; this is no longer the case.

LightWave ServerTM performance was found to be extremely reliable, resulting in:

  • The removal of continuous in-house IPM development / maintenance
  • Minimal debug / analysis sessions

Using LightWave ServerTM Console, it is much easier to identify the dictionary IPM to generate the API, helping us to:

  • Identify the required IPM from the NonStop source code
  • Considerably reduce the frequent development and analysis discussions
  • Avoid the old IPM to C++ functions we had to implement

Previously, a NonStop developer would pass on the IPM structure from the NonStop code to a Windows developer who then integrates it into the Client code; inevitably when the code was then tested, incorrect results were obtained.

The investigation process would then most likely involve a NonStop and a Windows developer to debug each end of the communications in order to work out what and where the issue was.

With LightWave ServerTM and the new Web Interface, any issues can generally be resolved by the Windows developer with very little involvement of a NonStop developer. This has significantly helped reduce the development time.

Industry Standards

LightWave ServerTM supports Industry standard REST, JSON and HTTP, making it far easier to integrate within the new Reflex Client, which now utilises the C# and the .NET framework. As a result it requires far less code for the communication sessions between the Client and NonStop Servers, making it extremely reliable.

Due to a supplied list of request parameters and JSON replies, we have easily incorporated these within the new GUI, meaning that it’s highly unlikely there will be any future API/IPM rework requirements.


Now that we have a robust and easy-to-use communication platform, we are utilising LightWave ServerTM to refine our product set further.

With no lengthy engineering overheads, our development teams can concentrate on supplying our customers and partners with world class applications, systems, and payments monitoring solutions.

    At NuWave Technologies, our mission is to provide exceptional middleware and support at a great value to the HPE NonStop userbase. Our latest middleware products, LightWave ServerTM and LightWave ClientTM, allow customers to expose NonStop applications as REST APIs and to access REST services from their NonStop applications, respectively. Over the past two decades, NuWave has grown through new product development and forging relationships with partners that offer complementary technologies and services. We take great pride in delivering solutions that exceed our customers' expectations. NuWave can vastly improve the performance of your business. Use the form below to reach out, and let us show you how we can help. At NuWave, we have made several changes to try and do our part to protect the environment. This is of increasing importance to us given the urgency of the climate crisis. In the past couple of years, we have been able to cut down our paper use by about 90% by limiting printing, going paperless with vendors and service providers, and increasing our use of e-signatures. In 2019, we also made the decision to go completely virtual, allowing employees to work from home five days a week. This cuts back on energy use, pollution from commuting back and forth, and it reduces single-use plastic consumption. NuWave donates a portion of its proceeds to Ocean Conservancy, a nonprofit that champions science-based solutions to tackle the largest ocean conservation challenges we face. The organization believes that the ocean is at the center of the most important food, energy and resource issues of our time, and we agree! Ocean Conservancy mobilizes citizen advocates to facilitate change, and it shapes the political agenda for the ocean so sound decisions are made that sustain our planet and improve lives.

  1. Nice article. Glad to know that LightWave helped improve interfaces and hence eased GUI development.

    One comment on the description of Insider Technologies. There is no DSPP program in HPE from 2016. Instead we have the Partner ready for Technology Partners (PRfTP) program. Inside technologies may sign up for into this program.
