删除Oracle数据库中的已连接用户 [英] Dropping connected users in Oracle database

问题描述

我想使用sqlplus在Oracle DB中删除一些用户，但出现错误:

I want to drop some users in Oracle DB using sqlplus but I am getting error:

SQL> DROP USER test CASCADE;
DROP USER test CASCADE
*
ERROR at line 1:
ORA-01940: cannot drop a user that is currently connected

我按照SO中的链接查找了会话-

I followed the link in SO to find out the sessions - Dropping a connected user from an Oracle 10g database schema

但是当我运行命令时，我没有得到任何结果:

But when I ran the command I am not getting any results:

SQL> select sid,serial# from v$session where username = 'test';

no rows selected

在这种情况下，请帮助我如何删除用户.

Please help me how to drop users in this case.

推荐答案

用户都是v$session中的大写字母(和数据字典视图).如果您与大写字母匹配，则应该找到要杀死的会话.

Users are all capitals in v$session (and data dictionary views). If you match with capitals you should find your session to kill.

SELECT s.sid, s.serial#, s.status, p.spid 
  FROM v$session s, v$process p 
 WHERE s.username = 'TEST' --<<<--
  AND p.addr(+) = s.paddr
 /

传递用户TEST的实际SID和SERIAL#值，然后删除用户...:

Pass actual SID and SERIAL# values for user TEST then drop user...:

ALTER SYSTEM KILL SESSION '<SID>, <SERIAL>'
