drop user 报错ora-00604

问题描述：

SQL> show user

USER is "SYS"

SQL> drop user efmis_zhongyang cascade;

drop user efmis_zhongyang cascade

*

ERROR at line 1:

ORA-00604: error occurred at recursive SQL level 1

ORA-38301: can not perform DDL/DML over objects in Recycle Bin

排查问题思路：

sql_trace跟踪sql：

SQL> alter session set sql_trace=true;

Session altered.

SQL> drop user efmis_zhongyang cascade;

drop user efmis_zhongyang cascade

*

ERROR at line 1:

ORA-00604: error occurred at recursive SQL level 1

ORA-38301: can not perform DDL/DML over objects in Recycle Bin

SQL> alter session set sql_trace=false;

Session altered.

通过以下语句确认跟踪文件位置：

select d.value || '/' || lower(rtrim(i.instance, chr(0))) || '_ora_' ||

p.spid || '.trc' trace_file_name

from (select p.spid

from sys.v$mystat m, sys.v$session s, sys.v$process p

where m.statistic# = 1

and s.sid = m.sid

and p.addr = s.paddr) p,

(select t.instance

from sys.v$thread t, sys.v$parameter v

where v.name = 'thread'

and (v.value = 0 or t.thread# = to_number(v.value))) i,

(select value from sys.v$parameter where name = 'user_dump_dest') d;

/u01/oracle/diag/rdbms/orcl/orcl/trace/orcl_ora_15959.trc

查看跟踪文件有如下信息：

EXEC #46948114736296:c=5999,e=5848,p=0,cr=26,cu=3,mis=0,r=0,dep=1,og=4,plh=0,tim=1459587911014685

ERROR #46948114738488:err=604 tim=1459587911014757

通过ERROR #46948114736296:err=38301可以得到oracle要执行语句为：

=====================

=====================

可以从上看到现在删除用户efmis_zhongyang要删除的是回收站对象"EFMIS_ZHONGYANG"."BIN$LR983/P8HqDgUyQDqMBbSw==$0"

登录SQL> conn efmis_zhongyang/1
