删除用户ORA-00604和ORA-00054

我执行了一个impdp，但它没有完成，因为表空间中没有空间。 我停止了impdb，现在我需要删除新建用户及其下的对象： SQL> drop user TEST cascade; drop user TGK_EXOR_IFIL_008_432 cascade * ERROR at line 1: ORA-00604: error occurred at recursive SQL level 1 ORA-00054: resource busy and acquire with NOWAIT specified or timeout expired 我没有在这个数据库上找个此用户的任何会话： SQL> select * from v$session where username = 'TEST'; no rows selected 解决： impdp要么仍在运行，要么正在回滚导入本身。 您可以尝试等待它手动完成或终止它。找到它： select o.object_name as "object_name",        s.sid as "sid",        s.serial# as "serial#",        s.username as "username",        sq.sql_fulltext as "sql_fulltext"   from v$locked_object l, dba_objects o, v$session s,        v$process p, v$sql sq   where l.object_id = o.object_id     and l.session_id = s.sid and s.paddr = p.addr     and s.sql_address = sq.address;
