Use "alter table <t> enable row movement" on the table to enable row movement in a table. Oracle requires this explicitly set on a table, probably because when a row moves to another partition, it's rowid will change and may cause unexpected behaviour if your application relies on rowids (when a row migrates implicitly to another block inside a table segment, then its rowid won't change despite the fact that the actual row data moved to another block).
