ChangeMan ZMF Modernization Guide

ChangeMan ZMF is a change management tool for application software releases on z/OS. It tracks all application changes, allowing for backout capabilities and impact analysis reporting. It helps organizations control and audit the software development lifecycle.

ChangeMan ZMF is a system designed to manage the software development lifecycle. It provides a structured framework for controlling changes, promoting code, and managing releases.

Organizations that develop and maintain applications on the z/OS platform, particularly those in regulated industries like banking, finance, and insurance, commonly use ChangeMan ZMF. Larger enterprises with complex application landscapes benefit most.

A company should consider ChangeMan ZMF when they need to improve control and auditability over their software development process, reduce the risk of deployment failures, and ensure compliance with regulatory requirements. It is especially useful when managing complex application dependencies.

Alternatives to ChangeMan ZMF include Endevor, ISPW, and other change management solutions tailored for the z/OS environment. Each offers a different approach to managing the software development lifecycle.

ChangeMan ZMF runs on the z/OS platform and requires specific subsystems to be active. It operates within an LPAR and is tightly integrated with the z/OS environment.

ChangeMan ZMF typically integrates with security systems like RACF, ACF2, or Top Secret for authentication and authorization. It also integrates with other development tools and deployment automation solutions.

ChangeMan ZMF uses a relational database, such as DB2, to store metadata about changes, packages, and approvals. This database is critical for tracking and reporting on the software development lifecycle.

ChangeMan ZMF exposes APIs that allow integration with other systems and tools. These APIs can be used to automate tasks, retrieve information, and trigger actions within ChangeMan ZMF.

ChangeMan ZMF provides business value by improving the reliability and speed of application deployments, reducing the risk of errors, and ensuring compliance with regulatory requirements. It also provides audit trails and reporting capabilities.

Without ChangeMan ZMF, organizations may experience increased deployment failures, longer lead times for releases, difficulty in tracking changes, and potential compliance issues. This can lead to business disruptions and increased costs.

ChangeMan ZMF helps organizations manage complex application dependencies by providing impact analysis reports and dependency tracking features. This allows developers to understand the potential impact of changes before they are deployed.

ChangeMan ZMF integrates with security systems like RACF, ACF2, and Top Secret to control access to mainframe datasets and resources. It uses role-based access control (RBAC) to manage user permissions.

ChangeMan ZMF supports various authentication methods, including password-based authentication and integration with external security managers (ESM) like RACF. It also supports multi-factor authentication.

ChangeMan ZMF provides audit logging capabilities that track all changes made to the system, including user actions, approvals, and deployments. These logs can be used for compliance and security auditing.

ChangeMan ZMF is typically deployed on-premise within the z/OS environment. It requires a dedicated team to manage and maintain the system, including monitoring, configuration, and troubleshooting.

Implementing ChangeMan ZMF requires expertise in z/OS, change management processes, and security administration. Common challenges include integrating with existing systems, configuring security settings, and training users.

Ongoing operational requirements include monitoring system performance, managing user access, applying maintenance updates, and troubleshooting issues. Regular backups of the ChangeMan ZMF database are also essential.
