Table Locks

query to get the locked tables in oracle :

SELECT l.inst_id,SUBSTR(L.ORACLE_USERNAME,1,8) ORA_USER, SUBSTR(L.SESSION_ID,1,3) SID,
S.serial#,
SUBSTR(O.OWNER||’.’||O.OBJECT_NAME,1,40) OBJECT, P.SPID OS_PID,
DECODE(L.LOCKED_MODE, 0,’NONE’,
1,’NULL’,
2,’ROW SHARE’,
3,’ROW EXCLUSIVE’,
4,’SHARE’,
5,’SHARE ROW EXCLUSIVE’,
6,’EXCLUSIVE’,
NULL) LOCK_MODE
FROM sys.GV_$LOCKED_OBJECT L, DBA_OBJECTS O, sys.GV_$SESSION S, sys.GV_$PROCESS P
WHERE L.OBJECT_ID = O.OBJECT_ID
and l.inst_id = s.inst_id
AND L.SESSION_ID = S.SID
and s.inst_id = p.inst_id
AND S.PADDR = P.ADDR(+)
order by l.inst_id  ;

Or you can do the below :

 select * From v$locked_object;
select * From v$session where SID = ”;
select * from dba_objects where object_id = ”;

 Locked objects :

Select object_name, owner, object_type from dba_objects
Where object_id in (select object_id from v$locked_object);

KILL SESSION COMMAND

ALTER SYSTEM KILL SESSION ‘SID,Serial#’ IMMEDIATE;
