This lets you perform space reclamation efficiently, without the high impact of unload and reload processing. Functions for rapid database changes, IOVF and SDEP extension, and more efficient unloading and reloading also help streamline your reorgs.

Examine, verify, and view reports on pointer data, including segment pointers, root addressable pointers (RAPs), and SDEP pointers. Current and historical reports can help you monitor and manage performance characteristics, space usage, and physical attributes of DEDBs. You can also use the tool to model the effect of potential DEDB changes before performing them. Auxiliary features also allow VSAM zap/dumps, reporting on SDEP space usage, and invocation of DEDB randomizing routines.
