解决方法：

实际上要么就是等，等到资源释放。要么就是删除sid。

1、查询object_id

select object_id from dba_objects where object_name=UPPER('TBL_1');

-------

1199531

2、根据object_id查出session

select sid from v$lock where id1=1199531;

--------

186

3、根据sid查询SERIAL#

select serial# from v$session where sid=186;

----

57893

4、

alter system kill session '186,57893';
