Dealing with orphan lob

Question

Oracle 10.2.0.4 EE on HP-UX 11.23
I seem to have "acquired" an orphaned lob:
SQL> select object_type, object_name
  2  from dba_objects
  3  where owner='OPS$STEVENSE';
OBJECT_TYPE         OBJECT_NAME
LOB                 SYS_LOB0000120564C00036$$
  1  select segment_name, segment_type from dba_segments
  2* where owner='OPS$STEVENSE'
SQL> /
SEGMENT_NAME                   SEGMENT_TYPE
BIN$UH6CiZpAVujgRAAaSwaUUg==$0 TABLE
BIN$hDEyxtzAG7vgRAAaSwaUUg==$0 TABLE
SYS_IL0000120564C00036$$       LOBINDEX
SYS_LOB0000120564C00036$$      LOBSEGMENTTwo tables in the recyclebin? Could the lobs be orphaned from a DROP TABLE?
The segments listed in my query on dba_segments don't show up in the recyclebin:
SQL> select object_name, original_name, type from recyclebin;
SQL> /
OBJECT_NAME                    ORIGINAL_N TYPE
BIN$crNFpQ4GNb3gRAAaSwaUUg==$0 DBSRROWN   TABLE
BIN$crNFpQ4FNb3gRAAaSwaUUg==$0 MR_TBL     TABLE
BIN$crNFpQ4ENb3gRAAaSwaUUg==$0 DEFROLES   TABLE
BIN$crNFpQ4DNb3gRAAaSwaUUg==$0 DEFUSERS   TABLE
BIN$crNFpQ4CNb3gRAAaSwaUUg==$0 DBSRRRPT   TABLE
BIN$crNFpQ4BNb3gRAAaSwaUUg==$0 DBSRREXP   TABLE
BIN$crNFpQ4ANb3gRAAaSwaUUg==$0 DBSRRIN    TABLE
7 rows selected.What about dba_lobs?
SQL> select table_name, segment_name
  2  from dba_lobs where owner='OPS$STEVENSE';
TABLE_NAME                     SEGMENT_NAME
BIN$hDEyxtzAG7vgRAAaSwaUUg==$0 SYS_LOB0000120564C00036$$Looks like my lob belongs to a table that has been dropped, but is no longer in the recyle bin.
Any suggestions on how to clean this up?

I do'nt know whether it is relevant or not:
"I think you may have done your purge and your recreate in difference schema, as the purge should have made it impossible to do a 'flashback table to before drop'. If that's not the case, then something went wrong with the purge if it hid the table from the flashback, but didn't actually drop it from the database."
LOB indexes are not dropped when drop a table

Girish SharmaThat discussion looked almost identical to my situation. I had dropped a table, but when I tried to flashback to before drop, it told me the table wasn't in the recyclebin. I had not purged the recycle bin, and the DROP had occurred only a few minutes before. All very strange. Looks like I'll have to open an SR. Fortunately, this is just housekeeping and not a pressing matter.
