Supporting & maintaining your IBM i applications

Are your IBM i applications no longer supported? IT staff responsible for your IBM i nearing retirement?

Do you have bespoke applications developed in-house or by third-parties that you can no longer maintain? Or maybe you’ve got a plan to ‘retire your IBM i’ in the next few years, but need help to support your applications in the meantime.

With a team of over 40 UK-based IBM i developers and specialists we can provide you with flexible support and maintenance options to meet your businesses needs; extend the life of your IBM i applications; mitigate the risks associated with unsupported applications; and ensure business continuity.

Our IBM i specialists can provide anything from a technical help desk to system monitoring, additional staff resources to a fully managed service – and everything in between.

We can carry out services at your premises, remotely or a combination of the two.

Regardless of whether your IBM i is part of your long term strategic plan or not, we can ensure that the ‘lights are kept on’ and the applications running on it keep supporting your business.



Modernising your IBM i applications

“They are brilliant systems but look dated and green screen or DOS like. we need to make it easier for new users to use the system.”

“The applications running on our IBM i are absolutely critical to our business. We need to be able to access them in a web browser – and they need to be easy to use for all our staff.”

Sound familiar?

Whether you are looking for the right IBM i development tools, some additional resources to help kick start or complete a project, or want Proximity to manage the whole project, we have unrivalled experience in developing and transforming IBM i applications.


AS400 / IBM i / iSeries application development

Bespoke business applications: IBM i & multi-platform application development

Whatever the challenge, Proximity can design and build business critical IBM i or multi-platform business applications using technologies such as PHP, Java, JavaScript, jQuery, AJAX, HTML, JSON, CSS or RPG.

Application maintenance can either be managed by your programmers, or Proximity can handle that as well.


AS400 / IBM i / iSeries Green Screen to Web GUI Mobile App

Mobile business applications: mobile App & responsive web applications

With the proliferation of mobile devices, it is increasingly important to provide access to business applications regardless of location or device.

We have experience of developing mobile applications, responsive web applications or creating web-enabled green screen applications that are also mobile-optimised.

AS400 / IBM i / iSeries Green Screen to Web GUI

Web GUI for green screens: web-based GUI for 5250 green screens

Proximity can help you bring your existing 5250 green screen applications to the web.

We can modernise existing RPG and COBOL applications to deliver a modern web-based GUI while at the same time customise emulated screens to include advanced functionality.

With PHP on the IBM i, we can develop new functions or rewrite existing ones which are blended with the 5250 functions which all run in a single browser session with no tabbing, launching or navigating required.

AS400 / IBM i / iSeries application development open source

Open source applications on the IBM i

Since IBM and Zend first introduced PHP to the IBM i in 2006 the open source language has become the most popular choice for web and mobile development on the IBM i platform. The introduction of Node.js in 2014 has added another powerful language to the open source stable on the IBM i.

Not only do Proximity design, build and maintain innovative and scalable business-critical web applications for organisations large and small across Europe and beyond, we also provide a number of tools to help developers working on the IBM i to create powerful open source applications.


AS400 / IBM i / iSeries application development BI dashboard

Business Intelligence: visualise data & make better business decisions

Having access to relevant business KPI’s can help organisations of any size make better decisions. Whether it is identifying and exploiting opportunities for growth, mitigating risks or managing day-to-day operations business intelligence (BI) tools can be invaluable.

Confronted with screen after screen of data, it can be difficult for businesses to sift through and find the meaningful and actionable. Dashboards, web reports and queries can provide organisations with real-time, web-based visual picture of your business.

Developed so that they can be accessed from a browser on any device (desktop, tablet or mobile), we design BI tools so you can view a quick snapshot and drill down into specific data sets.

Helping you get the most from your IBM i applications. Now and into the future

We’ve worked with lots of companies whose IBM i and the applications they run on it are absolutely part of their long term IT strategy. They simply work and reliably ‘do the job’ for them.

Over the years, their developers have changed bits of code on their ERP system, added a bit of functionality to their warehouse management system, or tweaked how the application deals with sales orders so that they fitted the unique nature of the business.

However, as the code has grown and the amount of data stored has increased, the task of accessing that information to drive better business decisions, or further develop those applications into the future become more difficult.

Our IBM i specialists can help you make the most of your IBM i so you can leverage that investment to ensure maximum business advantage.

By providing an opportunity for external assessment of your IBM i applications we can help improve the effectiveness of your IT ecosystem. We can help you match IT and software functions to changes in your business requirements and strategy.

Working with you and your key stakeholders, we’ll deliver documented findings covering:

  • The current state of your business, identify business drivers and explore current IT and IBM i strategy
  • Scope future plans around your IBM i, PHP, Cloud based strategies and beyond etc.
  • An inventory of current code base by type and application area (if applicable)
  • Analysis of databases and application interfaces
  • A technology road map
  • Areas for better system and software operation
  • Scope for enhancements in your IBM i ecosystem.


IBM i / AS400 Application Support & Development

Providing extra IBM i staff resources when you need them

Finding the right staff with the right skills to maintain, support and develop your IBM i applications can be difficult.

According to the results from various surveys into the state of the IBM i Marketplace over the past few years, the lack of staff with IBM i development skills is ranked amongst companies top concerns.

When skilled IBM i developers retire, or move onto another company, they take their technical knowledge with them, leaving organisation’s business-critical applications at risk. The lack of skilled resources can also mean that critical IBM i development and modernisation projects are delayed, or, in some cases postponed or cancelled.

Proximity can provide highly skilled and experienced IBM i specialists to help you bridge those skills gaps.

We can tailor our service to meet your needs – everything from supplementing your existing IT team; providing additional resources to kick start or complete a development or transformation project; or providing support on a contract basis.
