drop tablespace 的问题[@more@]有个tablespace没有用了，我想drop，可是报这样的error，麻烦帮忙看看，谢谢

SQL> show user
USER is "SYSTEM"
SQL> DROP TABLESPACE LCMA_MSR_IDX INCLUDING CONTENTS AND DATAFILES;
DROP TABLESPACE LCMA_MSR_IDX 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


这个tablespace的一些信息
select * from dba_segments where TABLESPACE_NAME='LCMA_MSR_IDX';
查询结果
BIN$GDkE9DvZHYDgQKoKQAFzpQ==$0

SELECT * FROM user_recyclebin;
BIN$FvVN6LQu9PPgQKoKQAE16g==$0
BIN$Fy8uRfbs17jgQKoKQAEChw==$0
BIN$IuRP7VaBUMvgQKoKPwFDzQ==$0
BIN$IuRP7VaCUMvgQKoKPwFDzQ==$0
BIN$GRHUVW3LaljgQKoKPwEJlQ==$0
BIN$GDkE9DvaHYDgQKoKQAFzpQ==$0
BIN$GRHUVW3JaljgQKoKPwEJlQ==$0
没有上面查出来的值，这个怎么回事？我要怎么样才能drop 这个tablespace？
