    I’ve just study how is it with reorganization in DB2 10.5, because online table reorg by auto maintenance was suspended (limited to table lower then 1kB) and now is recommended use ITC tables for archived tables and hold free space in table if is are only repeatedly cleaned. Free space will be reused by new records.

    There are good docs about it:
