Row lock: How to find a row that is locked in Oracle

Here is the nice script for finding the row lock (hoping you will find the locked objects easily) 

select	do.object_name
,	row_wait_obj#
,	row_wait_file#
,	row_wait_block#
,	row_wait_row#
,	dbms_rowid.rowid_create (1, ROW_WAIT_OBJ#, ROW_WAIT_FILE#, 
				ROW_WAIT_BLOCK#, ROW_WAIT_ROW#)
from	v$session s
,	dba_objects do
where	sid=&sid
and s.ROW_WAIT_OBJ# = o.OBJECT_ID ;

select * from tablename where rowid='';

Notes on ROW_WAIT_* columns in v$session,
ROW_WAIT_OBJ#
NUMBER
Object ID for the table containing the ROWID specified in ROW_WAIT_ROW#

ROW_WAIT_FILE#
NUMBER
Identifier for the datafile containing the ROWID specified in ROW_WAIT_ROW#. This column is valid only if the session is currently waiting for another transaction to commit and the value of ROW_WAIT_OBJ# is not -1.

ROW_WAIT_BLOCK#
NUMBER
Identifier for the block containing the ROWID specified in ROW_WAIT_ROW#. This column is valid only if the session is currently waiting for another transaction to commit and the value of ROW_WAIT_OBJ# is not -1.

ROW_WAIT_ROW#
NUMBER
The current ROWID being locked. This column is valid only if the session is currently waiting for another transaction to commit and the value of ROW_WAIT_OBJ# is not -1.

-Thanks
