Effect of RPA on Mainframe Automation

RPA or Robotic Process Automation is a new form of business process automation that automates tedious and repetitive processes of traditional IT companies. The rapid adoption of the technology can largely be owed to its high ROI (Return on Investment). The technology can also be used in conjunction with AI for better modernisation efforts. The industry has grown largely in the past few years. UiPath, a major RPA organisation, recently went public and has reported a market capitalisation of over $32 billion. RPA has become popular due to its ability to imitate human behaviour. Software robots can understand and interpret the information displayed on screens and can respond with human-like responses. However, robots can do the process faster and more consistently than any human.


RPA makes businesses streamline their workflows, making them more profitable, flexible, and responsive. As mundane tasks can be delegated to the computer, employee satisfaction also improves, leading to higher productivity. The software is also more accurate than its human counterparts and saves tremendous costs.

Other Opportunities

It is obvious now that RPA has many benefits for businesses and cannot be overlooked. However, there are other business aspects that can benefit from RPA systems: mainframes. Mainframes are ubiquitous in the business world. They perform some very critical tasks for the world’s largest organisations. For instance, the banking sector heavily depends on mainframes. 92 of the 100 top banks use mainframes. However, the mainframe needs to be modernised, and that would be expensive. This is where RPA comes in.

RPA interacts with mainframes for data extraction and analysis. Screen scraping is primarily used. However, multi-screen configurations and complex processes limit its applications. Hence, screen scraping becomes highly inefficient and cannot scale well in many environments. However, the implementation of integration software can help. HostBridge Technology’s JavaScript Engine, developed 20 years ago, allow integration and orchestration with IBM mainframes.

Another challenge faced when using RPA for mainframes is the lack of APIs. Mainframes usually use only a limited number of APIs that cannot be used for efficient screen scraping. Additionally, mainframes usually use applications like CICS to handle huge workloads of transactions.

Hence, integrating RPA with the mainframes is the most efficient approach. For example, imagine an attended bot that can only be activated by the end-user with a specific action. In such a scenario, a human would perform the first few tasks of a manual process and, based on the responses, and the bot will complete the next 15 to 20 steps in a matter of seconds. Of course, these bots may not automate end-to-end tasks. However, they will accelerate a large chunk of the manual process that may be executed thousands of times a day. Hence, integrating bots into the mainframe provides a scalable, high-performance integration path that avoids the shortcomings of screen-scraping.

In any case, the opportunity for RPA integration with the mainframe is enormous. But, the pandemic has pushed most businesses online and created an urgency for this. Though RPA technology and integration have improved over the years, there is still much room for innovation.
