用如下语句查询锁死的表:
select p.spid,
a.serial#, c.object_name, b.session_id, b.oracle_username, b.os_user_name from v$process p, v$session a, v$locked_object b, all_objects c where p.addr = a.paddr and a.process = b.process and c.object_id = b.object_id; 查询出被锁表:表解锁
alter system kill session 'sid,serial#';
alter system kill session '584,2178';
