Dataset Optimizer

Dataset Optimizer's architecture comprised several key components: data collectors, analysis engines, and reporting modules. Data collectors gathered information from z/OS SMF records and VSAM datasets. Analysis engines processed this data to identify performance bottlenecks and fragmentation.

Reporting modules generated reports for users. Communication between components was primarily through internal z/OS mechanisms. The product used VSAM datasets to store configuration data and collected performance metrics.

It did not typically rely on external databases. Administrative interfaces were provided through ISPF panels and batch jobs. User management was handled through z/OS security systems like RACF, ACF2, or Top Secret.

Key commands included `ANALYZE` for identifying fragmentation and `REPORT` for generating utilization reports. Configuration was managed through parameter files and JCL procedures. Dataset Optimizer supported z/OS security features for authentication and authorization, including RACF, ACF2, and Top Secret.

It used z/OS security access control lists (ACLs) to manage access to datasets and functions. Role-based access control (RBAC) was implemented through z/OS security profiles. Audit trails were generated through SMF records, capturing user activity and system events.
