Description: The number of times that hash join data exceeded the available sort heap space.
Usage: At the database level, if the percentage of "Hash Join Small Overflows" is greater than 10% of this value, then you should consider increasing the sort heap size. Values at the application level can be used to evaluate hash join performance for individual applications.
