Abstract:

The principal objective of this paper is to demonstrate the capabilities of legacy mainframes to support and use in smart phones and mobile applications devices. Legacy mainframes are trusted backbone platforms for executing critical business transactions. They are robust, reliable, scalable, and most importantly, resilient. Mainframe ecosystems have evolved to stay relevant, and despite their bad press, they have contributed to major technology milestones in the last decade.96 of the world's top 100 banks, 23 of the top 25 US retailers, and 9 out of 10 of the world's largest insurance company’s still use mainframes. Mainframes process roughly 30 billion business transactions per day, including most major credit card transactions and stock trades, money transfers, manufacturing processes, and ERP systems. Across the globe, more people now use mobile devices as their primary means of obtaining information and requesting services over the Internet. This shift is due to the convenience of being able to carry devices wherever they go, along with their user-friendly and intuitive nature. There have been many discussions on how to integrate the different capabilities and features of mainframes with the features that are required on a mobile application. The introduction of web services capabilities in CICS Transaction Server V3 provided the fundamental building blocks of service connectivity, enabling the adoption of service-oriented architecture (SOA), and underpinning today’s mobile solutions. CICS has continued to add new capabilities to the run time. From a mobile perspective, the introduction of the CICS TS Feature Pack for Mobile Extensions provides JSON and Representational State Transfer (REST)-conforming (RESTful) web service support, further enhancing the options for enterprise applications to mobile devices. Customers around the world use CICS TS to host hundreds of millions, and in some cases billions, of transactions per day. As the number of mobile devices worldwide continues to grow, so does the variety and volume of workload that they drive. CICS has the capacity to scale up in support of this increasing mobile workload, providing an exceptional platform for hosting mobile workloads.
