Monitor database space utilization

IBM® IMS Tools Base for z/OS® IMS Tools Knowledge Base provides an infrastructure for common information repositories for IMS system management. It provides centralized management of various types of repositories.

The reports that are generated by the IMS Database Solution Pack products can be stored in a repository. You can search historical copies of those reports by database name, date and time, or other search criteria.

Threshold criteria for detecting database exceptions and recommendations can also be defined and stored in a repository. These resources are used by the Smart Reorg utility of IMS Database Reorganization Expert and IMS Online Reorganization Facility to provide the conditional reorganization capability. Jobs with this capability enabled collect database statistics data and store the data in the Sensor Data repository. The data is evaluated against the threshold criteria to decide whether to reorganize the database.

Two components of IMS Database Solution Pack take advantage of the Sensor Data repository: IMS High Performance Pointer Checker and IMS High Performance Image Copy. You can generate sensor data as a by-product of running your normal IMS HP Pointer Checker and IMS HP Image Copy jobs. This functionality is called the Integrated Database Sensor function.

Additionally, IMS Database Solution Pack includes Stand-alone Database Sensor, whose sole function is to collect and print sensor data. These components, when used together with IBM IMS Tools Base for z/OS Autonomics Director and IMS Administration Foundation features of IBM Unified Management Server for z/OS, provide a comprehensive database space monitoring environment.
