Mainframe Navigation: z/OS Commands and ISPF Panels

Mainframes remain the backbone of global enterprise computing, yet navigating these powerful systems can feel intimidating to newcomers. This course demystifies mainframe environments, giving you the confidence to interact with z/OS systems using traditional and modern interfaces. You will transition from having zero mainframe experience to comfortably navigating the z/OS environment. By reading through clear, structured explanations, you will learn how to execute commands, manage datasets, and use standard panel interfaces. You will also explore how modern development practices are bridging the gap between traditional mainframe systems and contemporary developer workflows. What you'll learn: - Understand foundational mainframe architecture, z/OS terminology, and core system concepts. - Navigate the ISPF user interface using panels, menus, and keyboard shortcuts. - Execute TSO/E commands to manage system resources and interact with the operating system. - Create, edit, and organize partitioned and sequential datasets. - Submit and monitor batch jobs using Job Entry Subsystem (JES) commands. - Explore modern mainframe integration using Unix System Services (USS) and command-line tools. The course begins with essential terminology and structural concepts before guiding you through step-by-step written walkthroughs of TSO commands and ISPF panel navigation. You will progress from basic file operations to executing batch jobs and understanding modern mainframe access methods. This course is designed entirely for beginners with no prior mainframe experience. Anyone looking to start a career in enterprise computing or systems administration will find this foundational guide accessible and practical.
