Example 3. DBX and DBY exist, DBZ is to be added

In example 3, DBY must be reorganized to add the counter field to the segment C prefix. DBIL must be specified in the control statement for DBY. DBX must be reorganized because an initial load (DBIL) of the logical parent (segment C) assumes an initial load (DBIL of the logical child).

Example 3 is shown in the following figure.

Figure 1. DBX and DBY exist, DBZ is to be added
DBX has SEG A and physical child SEG B. DB Y has SEG C. DBZ contains SEG D and physical child SEG E. Logical relationship exists between SEG B and SEG C. SEG C is to be the logical parent of SEG E.

The procedure for this example (and all conditions and considerations) is exactly the same as example 2.
