SELECT s.username,

decode(l.type,'TM','TABLE LOCK',

'TX','ROW LOCK',

NULL) LOCK_LEVEL,

o.owner,o.object_name,o.object_type,

s.sid,s.serial#,s.terminal,s.machine,s.program,s.osuser

FROM v$session s,v$lock l,dba_objects o

WHERE l.sid = s.sid

AND l.id1 = o.object_id(+)

AND s.username is NOT Null
