Reclaim space in tablespace with partitions

edited Dec 18, 2016 4:00AM in Database Administration (MOSC) 2 commentsAnswered

In 11.2.0.4 data warehousing environment, a table of size 38G has its table and index partitions, sub-partitions spread among different tablespaces along with a main tablespace. All the tablespaces hosting partition and sub-partition data ONLY are highly fragmented. I believe to reclaim space i will have to execute ALTER TABLE ..MOVE command. I am not sure how much time it takes. Is it possible to re-organize particular tablespace without having any impact on actual table? Please share your thoughts and suggestions.

Thanks,
