What Is the TPF System?

The Transaction Processing Facility (TPF) system is an operating system that works with application programs to process transactions for customers in a real-time environment. For example, the TPF system can be used for computing needs such as transaction processing, network switching, and front-end processing.

The TPF system is designed for businesses and organizations that have high online transaction volumes and large networks. Because of its high capacity and high availability characteristics, the TPF system is well-suited for environments where growth is expected to be very fast or unpredictable, or where there are high peak periods of transaction activity. It is especially useful for applications that need high capacity and extremely low cost per transaction. Figure 1 shows the types of user requests and data requirements that are handled by the TPF system.
