Are those missing tables - IOTs?
If so, you will not see them as table segments, they will show up as index
segments.

Hi,
I found this out the hard way to: dba_tables, all_tables, and user_tables also include views. Of course, views don't have segments.

They don't seem to be views, they are tables
SQL select view_name from user_views where view_name like 'DR$%';

Hi,

I think you will find that these tables
are index-organized-tables. The table

user_tables do not include views.

'PRCPV%';
TABLE_NAME

Guang Mei,

I don't know what naming convention Oracle
used for the intermedia IOTs - possibly they
left them to default.
Start with:
select table_name, index_name
from user_indexes
where table_name = '{one of the missing tables}'
;
You may find that there is a primary key index
with a name
