Model 204 V7.1


The amount (percentage) of free space required on a Table X page before it can be added to the reuse queue. The minimum percent is 1, the maximum is 100.

If XREUSE is set fairly high, and Table X fills up to the point where the reuse queue is empty and there is no room to increase XHIGHPG, considerable space might still be available on most pages. To prevent a file full condition, Model 204 tries to find space to add a new record on as many as 16 randomly selected pages. Under these circumstances, increase a file or set XREUSE lower.

The Table X reuse queue is built for only unordered or entry order files for which XSIZE is greater than zero.
