Goal

Theoretically, PCTUSED can be considered as low water mark and PCTFREE as the high water mark. If the space in a data block is such that there is less space left than PCTFREE, no new rows can be added in that block until the amount of space in the table is less than PCTUSED. This note provides the steps to calculate the proper value of the PCT_FREE.
