ORA-00054: resource busy and acquire with NOWAIT specified

翻译：ORA-00054: 资源正忙，要求指定 NOWAIT

问题如下：

1 SQL> conn scott/tiger

2 SQL> drop table student;

3 drop table student

4 

5 ORA-00054: resource busy and acquire with NOWAIT specified

解决问题思路：这个表正在被使用，有可能有lock，在dba权限下查看一下是否有locks，通过v$session，v$locked_object看看是谁锁了你想用的资源，有的话把session干掉，alter system kill session ‘sid，serial#’ 就可以了，再来drop

 1 SQL> select session_id from v$locked_object;

 2  

 3  SESSION_ID

 4  ----------

 5  92

 6  

 7  SQL> SELECT sid, serial#, username, osuser FROM v$session where sid = 92;

 8  

 9  SID SERIAL# USERNAME OSUSER

10  ---------- ---------- ------------------------------ ------------------------------

11  92 38 SCOTT kms

12  

13  SQL> ALTER SYSTEM KILL SESSION '92,38';

14  

15  System altered

16  

17  SQL> conn scott/tiger

18  Connected to Oracle Database 11g Enterprise Edition Release 11.1.0.6.0

19  Connected as scott

20  

21  SQL> drop table student;

22  

23  Table dropped

该类问题通用解决方案：

1 select session_id from v$locked_object; --首先得到被锁对象的session_id

2 SELECT sid, serial#, username, osuser FROM v$session where sid = session_id; --通过上面得到的session_id去取得v$session的sid和serial#，然后对该进程进行终止。

3 ALTER SYSTEM KILL SESSION 'sid,serial';

4 example:

5 ALTER SYSTEM KILL SESSION '13, 8';
