Description

The number of bytes on a Table X page which must be free in order to store a new extension record on the page. This parameter should be set to the average extension record length, which can be determined using the TABLEX RECLEN command. The parameter effectively reserves space for the expansion of existing records on a Table X page. The minimum space reserved is 0 bytes; the maximum is 6,140 bytes.
