IBM Z zOS is a repository of sample programs and resources for the z/OS operating system community.
The repository addresses the need for tools and educational materials that extend z/OS capabilities beyond what ships with the product itself. It organizes downloadable resources across functional domains including system management facilities, automation, container platforms, health checks, security, performance analysis, and workflow management. The materials span multiple z/OS release levels and include educational modules, sample code, and utility tools written primarily in REXX.
Organizations running z/OS systems should consider this repository when seeking community-contributed tools for specific operational tasks such as performance monitoring, system configuration, security administration, or capacity planning. The collection is particularly useful for teams evaluating z/OS capabilities, migrating workloads, or automating routine administrative functions. The repository explicitly carries no warranty and receives no formal IBM support, making it suitable for non-production exploration or as a starting point for internal tool development rather than as a replacement for supported IBM products.
Development activity shows consistent engagement with the community through an open issue and pull request process. The project maintains organized categorization of materials by functional area and release level, reflecting ongoing curation of contributed resources. Contributors are invited to participate in development and share improvements, with feedback directed to a dedicated contact address or through GitHub issues.
