查看对像锁
SELECT a.LOCKED_MODE, b.object_name, b.object_type
FROM v$locked_object a, user_objects b
WHERE a.OBJECT_ID = b.object_id;
查看DML锁
SELECT username,
v$lock.sid,
trunc(id1 / power(2, 16)) rbs,
bitand(id1, to_number('ffff', 'xxxx')) + 0 slot,
id2 seq,
lmode,
request
FROM v$lock, v$session
WHERE v$lock.TYPE = 'TX'
AND v$lock.sid = v$session.sid
AND v$session.username = USER;
查看DDL锁
有一个意义非凡的视图可用于查看这个信息，即 DBA_DDL_LOCKS 视图
select session_id sid, owner, name, type, mode_held held, mode_requested request
from dba_ddl_locks;
