See above (HASH_HI_DEN_LIM—High Density Limit for Hash Indexes).
HASH_LOW_DEN_LIM=nnn must be between 10 and 600; the default is 600. We recommend the value be lowered to between 200 and 300.
This option applies to this region’s users, regardless of which TSR they access. (An exception to this is a situation where a Release 6.0.3 or higher release application accesses a Release 6.0.2 or lower release VTS-TSR—in this case the region’s density limits are ignored.)
This option can be specified for all tableBASE interfaces except the VTS interface.
