Example 10. DBY exists, DBZ is to be added
In example 10, segment X might be considered a logical child if the key of segment D is at the correct location in segment X. DBY must be reorganized, because an initial load (DBIL) of the logical parent (segment D) assumes an initial load (DBIL) of the logical child.
In this example, you could use symbolic or direct pointers for segment X. Do not under any circumstances specify DBR in the control statement for DBY. If you do, the reload utility will not generate work records for segment D; the logical child pointer in segment D would never be resolved. The procedure for this example (and all conditions and considerations) is exactly the same as the procedures for example 9.
Example 10 is shown in the following figure.
