I think this is happening because when you DELETE data the High Water Mark(HWM) is not lowered. Essentially
you have not gained any freespace. If possible you could export remaining data truncate table then re-import.

Correct me if I am wrong here.

Hi All,

I have deleted 3 lakhs records from a large table. But there is no effect on tablespace i.e. before I delete the data freespace in TS is 100MB , after deletion also it is showing 100MB. What could be the reason ? How to get the freespace after deleting the data ?
Thanks
rukmini
