This IBM Redbooks publication is designed for a one-semester course intended to provide information systems students with the background knowledge and skills necessary to begin using the basic communications facilities of a mainframe-based system. It provides a broad understanding of networking principles and the hardware and software components necessary to allow the mainframe to participate in a high volume data communications network.  

This IBM® Redbooks® publication describes the functions of z/OS® Communications Server. z/OS Communications Server provides a set of communications protocols that support peer-to-peer connectivity functions for both local and wide-area networks, including the most popular wide-area network, the Internet.  

z/OS Communications server also provides performance enhancements that can benefit a variety of TCP/IP applications. 

Volume 2: z/OS implementation and daily maintenance, defining subsystems, IBM Job Entry Subsystem 2 (JES2) and JES3, link pack area (LPA), LNKLST, authorized libraries, System Modification Program Extended (SMP/E), IBM Language Environment 

Volume 3: Introduction to DFSMS, data set basics, storage management, hardware and software, catalogs, and DFSMS 

Volume 6: Introduction to security, IBM RACF®, digital certificates and public key infrastructure (PKI), Kerberos, cryptography and IBM z9® integrated cryptography, Lightweight Directory Access Protocol (LDAP), and Enterprise Identity Mapping (EIM) 

This site provides details about how to set up and configure a CI/CD pipeline including z/OS assets.  This site includes getting started information as well as detailed information on how to move into the pipeline. 

What exactly is DevOps - and how does DevOps' culture and practices fit into the mainframe world? 

Rosalind Radcliffe is here to answer these questions, explain why DevOps and the mainframe go together, and how taking advantage of DevOps' automation and modern ways of working can streamline your mainframe process. 

This Redbook discusses how mainframe applications can be modernized to take advantage of today’s hybrid cloud environment.  This paper presents at a high level various ways that applications can be updated or transformed to provide greater flexibility for today’s continuing business demands.  This is a good paper to start with to see how the various technologies you are learning as part of the development courses fit together within real client environments.  

If you work in the Mainframe space, you might be wondering if Git even applies to your work. In this video, Rosalind Radcliffe dispels myths, exposes lies, and sheds light on the many ways Git can bring value to your work.  

Love programming in Python?  

Then check out this video in which Rosalind Radcliffe explains why your love of the Python just might translate into a new love of the mainframe. 

Join Rosalind Radcliffe as she discusses how to turn your infrastructure into a strategic asset for AI. In this video, we'll cover the importance of modernizing your applications and optimizing your infrastructure for high-security, high-reliability, and high-throughput workloads. 

This Redbook provides the right introduction to APIs and their importance for exposing existing business function.  Again, this book is older so the products will have evolved from this point, but the fundamentals of understanding APIs remain and are valuable to learn.  

This Redbook explains how to update an existing CICS application to take advantage of capabilities such as exposing function as an API.   

This book uses a real example to help step through what you need to do with your program and in CICS.  This book will build on the basic CICS understanding.
