Understand how IBM Z operates across the enterprise.
IBM Z Systems Programming — Volume II: Program Execution and Enterprise Facilities builds on the architectural foundation established in Volume I and examines the facilities that support program execution, enterprise workloads, connectivity, storage, and system operations.
Explore program execution and recovery, interrupts, I/O architecture, channel subsystems, DASD, VSAM, catalogs, tape, JES2 and JES3, networking, VTAM, TCP/IP, CICS, IMS, Db2, DFSMS, z/OS configuration, and SMP/E.
Rather than treating these facilities as isolated technologies, this volume examines how they interact to support enterprise workloads. A problem that appears to originate in one subsystem may involve storage, workload management, networking, application design, or another interconnected component.
Ideal for: aspiring IBM Z systems programmers, working practitioners, application developers, infrastructure specialists, technical architects, and independent learners.
Experienced professionals can also use the volume as a structured technical reference for revisiting enterprise facilities and their relationships.
Professional perspective: This book provides structured technical education and professional reference. It complements hands-on work, mentoring, operational responsibility, and real-world experience; it does not replace them.
