did you try purge dba_recyclebin;

that should kill everyone's recyclebin.

Thanks, Joe

You can have it: Fast, Right or Cheap, pick 2 of the 3. Fast + Right is Expensive
Fast + Cheap will be incorrect.
Right + Cheap will take a while.

But emptying the recycle bin doesn’t get rid of them…

They are recycle bin objects. Query dba_recyclebin to see them..

Thanks

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  

BIN$Rxl0mZVtGWjgRAADupYzGQ==$0  

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.
