Block Size for Duplicate Record IDs

A blocking factor for duplicate key Record IDs can be specified using the DUPQTY parameter on the CREATE INDEX command. For best performance, the DUPQTY parameter for each index should closely resemble the index's distribution of duplicates. Indexes with high duplicate content should have high DUPQTY blocking factors, while more unique indexes should have low DUPQTY blocking factors.
