I have a rollback tablespace datafile. When I look at the tablespace through GUI tool it shows 2750m allocated 1813.73m used. When I am trying to reduce the size of the datafile to 2200m I get an error:ORA-03297 'FILE CONTAINS 115845 BLOCKS BEYOND REQUESTED RESIZE VALUE'.
I've already tried to coalesce that tablespace. It didn't change anything.
What is going on? What do I do?
