Changing the position of data in a segment
You cannot change the position of data in a segment using the reorganization utilities.
To make this kind of change, you must write your own unload and reload program, use field-level sensitivity, or use a tool, such as the IMS High Performance Pointer Checker for z/OS®, which includes a DB Segment Restructure utility.
