HASH_HI_DEN_LIM and HASH_LOW_DEN_LIM limit the density of the index for a hash table opened. These values are designed to prevent performance problems which can occur when inappropriately high values are used when defining hash tables (can result in a lot of key collisions in the table). Other problems occur if the difference between low and high density values is too small. A ratio of two thirds is now enforced: Low density may not be greater than two thirds of high density.
HASH_HI_DEN_LIM=nnn must be between 100 and 900 (10% and 90%); the default is 900. We recommend the value be lowered to 500.
This option applies to this region’s users, regardless of which TSR they access.
This option can be specified for all tableBASE interfaces except the VTS interface.
