Sequential dependent part

The sequential dependent part holds sequential dependent segments from roots in all UOWs in the area.

Sequential dependent segments are stored in chronological order without regard to the root or UOW that contains the root. When the sequential dependent part is full, it is reused from the beginning. However, before the sequential dependent part can be reused, you must use the DEDB Sequential Dependent Delete utility (DBFUMDL0) to delete a contiguous portion or all the sequential dependent segments in that part.
