SELECT SESS.SID,
       SESS.SERIAL#,
       LO.ORACLE_USERNAME,
       LO.OS_USER_NAME,
       AO.OBJECT_NAME,
       LO.LOCKED_MODE
  FROM V$LOCKED_OBJECT LO, DBA_OBJECTS AO, V$SESSION SESS
 WHERE AO.OBJECT_ID = LO.OBJECT_ID
   AND LO.SESSION_ID = SESS.SID;

//alter system kill session 'sid,serial#' 
ALTER SYSTEM KILL SESSION '1973,19979';
