IMS Space Management Utilities

The architecture of IMS Space Management Utilities was centered on the z/OS operating system. The main components included the HD pointer checker, the database segment restructure utility, and the space monitor. These components operated within the z/OS environment and communicated through system services and datasets.

The HD pointer checker analyzed IMS databases for data integrity, identifying and reporting pointer errors. The segment restructure utility reorganized database segments to optimize storage and improve performance. The space monitor tracked database space utilization, providing insights into storage needs.

SPACE`. Configuration involved specifying datasets, control parameters, and operational thresholds. The utilities did not expose any APIs or use network protocols, as they operated within the z/OS environment.

The primary storage mechanism was the IMS database itself, with datasets used for input, output, and configuration. This product is not supported. The recommended approach is to migrate to IMS System Utilities or third-party alternatives, which provide similar functionality with updated interfaces and features.

These alternatives offer enhanced capabilities and are actively maintained.
