Obtaining statistics from each subset with Sequential Subset Statistics

The Sequential Subset Statistics (SS-STATS) routine (FABISTAT) provides database administrators with statistical information, which is useful in determining how much relative space in the root addressable area needs to be allocated to each subset.

For each subset, SS-STATS provides statistics about the number of database roots and about the total length of database segments within the subset.

The SS-STATS is provided as an exit routine of the IMS High Performance Unload database unload utilities (that is, FABHURG1 and FABHFSU).
