Hi,
I have a limited access to objects in my database ( do not have access to many tables).
I have been allocated 300GB of size in my tablespace which allows me to create my objects.
Now, I want to find out how much of this tablespace size allocated to me have been used up. I do not have access to dba_data_files or dba_segments.
Is there a way out for me? Could anyone show me a way please?
