在alter/drop表空间时遇到错误ORA-38301,ORA-00604,purge dba_recyclebin 也不行

适用于：
Oracle Database - Enterprise Edition - Version 10.2.0.1 and later
Information in this document applies to any platform.

症状：
当你试图drop一个empty的tablespace时，遇到与recyclebin相关的错误 

SQL> drop tablespace TEST_TBS including contents and datafiles;
 drop tablespace TEST_TBS including contents and datafiles
 *
 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

尝试purge dba_recyclebin 并 offline该tablespace也不行：

SQL> purge dba_recyclebin;

DBA Recyclebin purged.

SQL> alter tablespace TEST_TBS offline;

Tablespace altered.

SQL> drop tablespace TEST_TBS including contents and datafiles;
 drop tablespace TEST_TBS including contents and datafiles
 *
 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 

原因：
查询 dba_segments显示该表空间内还有segments

SQL> select SEGMENT_NAME,SEGMENT_TYPE,owner from dba_segments where tablespace_name='TEST_TBS';

 SEGMENT_NAME                   SEGMENT_TYPE       OWNER
 ------------------------------ ------------------ ------------------------------
 BIN$Pks1AnxmMCTgQ8+Ct10wJA==$0 TABLE              ORACLE     
 BIN$Pks790fcQEzgQ8+Ct11ATA==$0 TABLE              ORACLE 

解决方案：

用该schema的owner登陆sqlplus，然后执行purge recyclebin，然后再删除drop tablespace

SQL> purge recyclebin;

SQL> drop tablespace TEST_TBS including contents and datafiles; 

若是这么还是不解决问题，最快速的变通方法就是disable掉recyclebin，再drop tablespace，再enable recyclbin

SQL> conn / as sysdba

SQL> alter system set recyclebin=off;

SQL> drop tablespace TEST_TBS including contents and datafiles;

SQL> alter system set recyclebin=on;

---提醒：11gR2里边，recyclebin貌似是静态参数。

若是上面的步骤不能解决问题，请用下面的方法：

1) sqlplus / as sysdba
2) ALTER SYSTEM SET recyclebin = OFF DEFERRED;
3) disconnect and exit sqlplus
4) sqlplus / as sysdba
5) drop tablespace........
6) sqlplus / as sysdba
7) ALTER SYSTEM SET recyclebin = ON DEFERRED; or ALTER SYSTEM SET recyclebin = ON;
