How to query locked tables in ORACLE and how to unlock and release sessions

ORACLE EBS operates a certain FORM interface, or when the background database operates a certain table, it is found that it is always in a "suspended death" state. It may be that the table is locked by a certain user, causing other users to be unable to continue the operation

--锁表查询SQLSELECT object_name, machine, s.sid, s.serial# 
FROM gv$locked_object l, dba_objects o, gv$session s 
WHERE l.object_id　= o.object_id 
AND l.session_id = s.sid;

Find the locked table, unlock

--释放SESSION SQL: 
--alter system kill session 'sid, serial#'; 
ALTER system kill session '23, 1647';
