Splitting the unloaded database data set

The FABIUNLS utility is used to speed up the database reorganization while converting databases randomized with DFSHDC40 into databases randomized with the Sequential Subset Randomizer.

FABIUNLS splits an unloaded database data set into multiple data sets as input to the IMS HD Reorganization Reload utility. The split data sets are sorted in the ascending order of subset ID so that a large databases can be reloaded in a reasonable amount of time.
