I have few huge DSO's >200 GB kind and this data is for a year. We delete (Selective Deletion) data regularly retaining 6th months rolling.
But the problem occurs when space is not released as expected and occupies Fragmented size.
Re-org is currently not an option as we have customer process challenges with BASIS.
If I create DSO partitions on month ,
1) Will space gets released , not occupying fragmented space.
DSO Loading and activation impact ( SID Gen is set to inactive)
