Oracle Apps: Kill a Locked session through Toad

Query All the Locked sessions using below SQL and based on your OBJECT find the session locking it

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 


Kill the session by below ALTER statement. To perform this operations you need to have full db access, if you face issue, check with your DBA.

ALTER SYSTEM KILL SESSION 'sid,serial#' IMMEDIATE;
