PIE/TSO Performance Group Manager

The architecture of PIE/TSO Performance Group Manager is centered around its ability to manage TSO performance at the application level. The main components include a CLI for administrative tasks, configuration files for defining application groups and performance settings, and integration with z/OS WLM for resource management. The CLI provides the primary interface for administrators to define application groups, assign them to performance groups, and monitor performance metrics.

Configuration files store the definitions of application groups and their associated performance group settings. These files are read by the system during initialization and whenever changes are made. The system integrates with z/OS security for authentication and access control, leveraging existing security profiles.

Communication between components is primarily through z/OS system calls and APIs. The system does not introduce its own encryption; it relies on the underlying z/OS security features. The product's design emphasizes ease of use and integration with existing z/OS environments, providing a streamlined approach to application-level performance management.

The system uses z/OS logging and auditing facilities for tracking configuration changes and user actions.
