need archivelog for logminer

 Below is the last_ddl_time:

select LAST_DDL_TIME,CREATED from dba_objects where object_name='DOWNLOADS';

LAST_DDL_TIME        CREATED

23-JUL-2013 11:03:33 23-JUL-2013 11:03:33

Now I want to know what ddl was issued on this table

For this logminer can give me an answer but how do I restore the archived log file of this time?
