Mainframe computers play a central role in the daily operations of many of the worlds largest corporations. Batch processing is still a fundamental, mission-critical component of the workloads that run on the mainframe and a large portion of the workload on IBM® z/OS® systems is processed in batch mode. This IBM Redbooks® publication is the second volume in a series of four in which we describe new technologies introduced by IBM to facilitate the use of hybrid batch applications that combine the best aspects of Java and procedural programming languages such as COBOL. This volume specifically focuses on the z/OS batch runtime. The audience for this book includes IT architects and application developers, with a focus on batch processing on the z/OS platform.

Mainframe computers play a central role in the daily operations of many of the world's largest corporations, and batch processing is a fundamental part of the workloads that run on the mainframe. A large portion of the workload on IBM® z/OS® systems is processed in batch mode. Although several IBM Redbooks® publications discuss application modernization on the IBM z/OS platform, this book specifically addresses batch processing in detail. Many different technologies are available in a batch environment on z/OS systems. This book demonstrates these technologies and shows how the z/OS system offers a sophisticated environment for batch. In this practical book, we discuss a variety of themes that are of importance for batch workloads on z/OS systems and offer examples that you can try on your own system. The audience for this book includes IT architects and application developers, with a focus on batch processing on the z/OS platform.
