SELECT B.OBJECT_NAME, B.OWNER, C.SID,C.SERIAL#,C.OSUSER, C.MACHINE, C.TERMINAL
  FROM V$LOCKED_OBJECT A, DBA_OBJECTS B, V$SESSION C
 WHERE A.OBJECT_ID = B.OBJECT_ID
  AND A.SESSION_ID = C.SID
  AND c.STATUS='INACTIVE'
  AND C.TYPE='USER'
  ORDER BY 1;
 

--解锁语句 
DECLARE
  V_SQL VARCHAR2(500);
  CURSOR C_SESSION IS
    SELECT B.OBJECT_NAME,
        B.OWNER,
        C.SID AS SESSION_ID,
        C.SERIAL# AS SERIAL#,
        C.OSUSER,
        C.MACHINE,
        C.TERMINAL
    FROM V$LOCKED_OBJECT A, DBA_OBJECTS B, V$SESSION C
    WHERE A.OBJECT_ID = B.OBJECT_ID AND A.SESSION_ID = C.SID
      AND C.STATUS = 'INACTIVE' AND C.TYPE = 'USER'
    ORDER BY 1;
BEGIN
  FOR GET_SESSION IN C_SESSION
    LOOP
      BEGIN
        V_SQL:='ALTER SYSTEM KILL SESSION '''||GET_SESSION.SESSION_ID||','||GET_SESSION.SERIAL#||''' IMMEDIATE';
