HASH_JOIN_ENABLED specifies whether the optimizer should consider using a hash join as a join method. When set to FALSE, hashing is not available as a join method. When set to TRUE, the optimizer compares the cost of a hash join with other types of joins, and chooses hashing if it gives the best cost. Oracle Corporation recommends that you set this parameter to TRUE for all data warehousing applications.
