May 1, 2026

Concise monthly summary for 2026-05 focusing on business value and technical outcomes. Key achievement was delivering the Zos_stat Resource Type Filter for zos_stat outputs, enabling filtering by resource types (data set, file, aggregate, GDG). This enhanced automation accuracy and reporting for IBM Z OS core workloads. The effort included documentation updates, test coverage, and a changelog fragment to support release notes. A bug affecting filtering of data set attributes was fixed, improving reliability of data extraction. Filter code was refactored for clarity and maintainability, with naming aligned to zos_stat_by_type. All changes adhere to pep8 and included tests for edge cases.

June 2025: Delivered targeted improvements for the IBM z/OS Ansible collection, focusing on documentation accuracy and automation readiness. Key changes include a documentation update for zos_copy block size when is_binary is true (block size corrected to 32720) with an accompanying changelog fragment, and an enhancement to the zos_stat module to expose explicit resource type indicators (isfile, isdataset, isaggregate, isgdg) plus an exists flag. These changes improve automation reliability, resource querying, and reduce troubleshooting time for IBM Z playbooks.

Apr 1, 2025

April 2025: Delivered core z/OS resource discovery enhancements and repository hygiene improvements for ansible-collections/ibm_zos_core. The team introduced the zos_stat module for retrieving facts from z/OS resources (MVS data sets, USS files, aggregates, and generation data groups) with a rich attribute set and support for multiple resource types. Added alias resolution in zos_stat, enabling querying data sets via aliases and automatic resolution to base names, accompanied by documentation. Completed repository housekeeping by removing obsolete dev tools and updating .gitignore and CI/workflows to streamline development. No critical bug fixes were recorded in this period.

Nov 1, 2024

November 2024: Delivered automation improvements in the IBM z/OS collection. Implemented asynchronous support for zos_job_submit to enable non-blocking job submissions, including refactoring of temporary file handling and added tests to validate the new async behavior. Hardened CI/testing for Ansible collections by addressing environment variable loading and escaping issues in tests for Ansible 2.17.1, reducing flaky test runs and improving reliability. These initiatives shorten automation run times, enhance developer productivity, and increase confidence in production automation across z/OS environments.
