今天在进行测试环境导数据的时候,需要记性drop user操作。在执行drop user的时候,提示:ORA-01940: cannot drop a user that is currently connected
SQL> drop user ecity ;
drop user ecity
*
ERROR at line 1:
ORA-01940: cannot drop a user that is currently connected
问题很明显,有用户在连接,不允许drop掉该user。
问题解决,记得KILL进程前,先看看是啥进程,哪台机连过来的,能否KILL等等。测试环境还好,生产无小事。
