(LOW-DENSITY) This is the density to which a hash table will be set when reorganized. Reorganization is done automatically when the HIGH-DENSITY is exceeded. LOW-DENSITY is an integer from 1 to an upper limit representing the density in thousandths.
The upper limit is the HASH_LOW_DEN_LIM option value established at installation or overriden in TBOPT dataset at execution time. LOW-DENSITY must be no greater than 2/3 of HIGH-DENSITY. LOW-DENSITY will be adjusted if it exceeds these limits.
