In this IBM® Redbooks® publication, we explain how to use the ACI™ BASE24-eps™ product on z/OS® . BASE24-eps is a payment engine that the financial payments industry uses. The combination of BASE24-eps and System z® is a competitive and attractive end-to-end retail payments solution for the finance sector.

Failure in a financial payments environment is a high-visibility customer service issue, and outages at any level have debilitating effects on customer loyalty. The entire payments cycle must be conducted in near real-time. In such an environment, high availability is a mission-critical requirement. In this guide, we demonstrate how you can achieve a high availability configuration for BASE24-eps on z/OS.

We begin by outlining the requirements of a payments system, and then we introduce the structure and functionality that the BASE24-eps product offers.We also describe the strengths and abilities of System z and z/OS and explain the technical and physical architecture of BASE24-eps on z/OS.

We guide you in designing a system layout and in installing BASE24-eps. Finally, we detail the numerous failure scenarios that we tested to verify the robustness of the solution.

BASE24-eps is an evolving product. The information that we provide in this book is specific to BASE24-eps release 08.2 and is subject to change in subsequent releases of the product.
