Dear All,

I have deleted a user with CASCADE option.

After deletion, the size of tablespace should be reduced.

But the tablespace size is same as before deletion of user.

Currently , that USER is deleted and not present in the database . Still space is not released after user deletion.

Please help me in the above query.

Thanks ,
Ganesh

There is no reason why dropping a schema would reduce the size of a tablespace. It might reduce the space used within a tablespace.

No, the space used in the tablespace reduces: you have more free space but the tablespace does not.
A tablespace does not shrink by itself, you have to shrink the files yourself and maybe you have to move some objects to be able to do so.
