In case 1), the occupancy level is dependent on the integer specified. It must not fall below
the following value:
integer
Minimum occupancy level [%] = x 100.
integer+1
This means that high occupancy levels are most easily obtained if records are stored in
sorted order. High occupancy levels reduce storage space requirements for tables and
result in shorter access paths.
In order to obtain high occupancy levels by dynamic reorganization, the following must be
taken into consideration:
High values for integer
– are more acceptable for pointer arrays, sort and SEARCH key tables than for lists;
– are more acceptable for records that remain unchanged than for frequently changing
records.
Dynamic reorganization cannot be used for dynamic sets; for multi-level tables it can only
be applied on the lowest table level. Duplicates tables cannot be dynamically reorganized.
The default value for integer is 2.
