删除数据库用户的时候经常会遇到这样的错误; ORA-01940: cannot drop a user that is currently connected 原因是有程序在连接我们需要删除的用户,我们删除用户之前一定要先把连接断掉; 1、查找帐号下哪些连接在运行: SELECT SID,SERIAL# FROM V$SESSION WHERE USERNAME='USERNAME'; 注意:此处需要大写 SQL> SELECT SID,SERIAL# FROM V$SESSION WHERE USERNAME='SSTEST'; SID SERIAL# ---------- ---------- 137 41813 335 25993 464 58747 500 9153 531 50402 629 9264 631 11237 664 36180 8 rows selected. 2、删除用户进程; SQL>ALTER SYSTEM KILL SESSION '137,41813'; System altered. SQL>ALTER SYSTEM KILL SESSION '33525993; System altered. 3、重新查看用户连接,并确认无连接在使用 SELECT SID,SERIAL# FROM V$SESSION WHERE USERNAME='SSCRM'; 4、删除用户 drop user sstest cascade ;
