Example 7: Reducing the size of realms

You can reduce the size of a realm by initially relocating records and small tables in the realm toward the beginning of the realm online in a RELOCATE run (see “Example 2: Relocation of all possible pages using the standard procedure”).

You can then reorganize the DBTT sections, CALC areas and set occurrences located at the back of the realm which cover several pages offline using the BREORG utility routine.

Finally you can also use BREORG to release the pages which have become free at the back of the realm and thus reduce the size of the realm.
