(HIGH-DENSITY) This is the value for the highest density a hash table may have. When an insertion of a row into a hash table would cause the HIGH-DENSITY to be exceeded, the table will be reorganized to match the LOW-DENSITY specification. HIGH-DENSITY is an integer from 1 to an upper limit representing the density in thousandths.
The upper limit is the HASH_HI_DEN_LIM option value established at installation or overridden in TBOPT dataset at execution time. HIGH-DENSITY must be at least 1.5 times LOW-DENSITY. HIGH-DENSITY will be adjusted if it exceeds these limits.
