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..

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
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.
