Log onto the segment owner via sqlplus and issue a "purge recyclebin" command. Thse will go away.  

You didn't say - but you are 10g. Now when you drop anything, it goes into the recyclebin.

Rather annoying if you ask me!

Subject: Weird Objects in DBA_SEGMENTS

I have spent the morning cleaning out a tablespace in an attempt to reclaim 800 GB of space and clean up my production data warehouse. To this end... I ran a BUNCH of  

ALTER TABLE <table> move tablespace <tablespace>;  

It "appeared" clean... nothing in dba_tables or dba_indexes.  

However, my life can't be that simple.  

The paranoid dba on my left shoulder urged me to look at dba_segments... so I did.  

select owner, segment_name, partition_name, tablespace_name, segment_type from dba_segments where tablespace_name = 'STAGEDAT01';  

there are a bunch of segments named similar to  


They "apparently" are tables and indexes.  

There are, however, apparently no actual extents... because

select * from dba_extents where tablespace_name = 'STAGEDAT01';

returns only the plan table that I want to drop anyway  

anyone have any ideas on what these BIN segments are?  

Thanks in advance.
