I used more ideas. but i can resolve this problem, because 

SELECT target_name FROM sysman.MGMT_TARGETS where target_type = 'oracle_emd'

 

I didn't find hosts. 

and

  exec mgmt_admin.cleanup_agent('db1:3872'); 

BEGIN 

mgmt_admin.cleanup_agent('db1:3872'); 

END; 

* ERROR at line 1: 

ORA-01403: no data found

ORA-06512: at "SYSMAN.MGMT_ADMIN", line 798 

ORA-06512: at line 1 

However i read from some forums. 

they told me "delete the TARGET_GUID from MGMT_EMD_PING and MGMT_EMD_PING_CHECK." 

I followed, but can't resolve 

So......... 

I had some idea. I found every tables, that they have "MGMT_*" names and TARGET_GUID be "CE6B5C2E232766E01D3803EB03D70128" ,


and then i deleted example

SQL> delete from MGMT_TARGET_ASSOC_INSTANCE where target_guid = HEXTORAW('CE6B5C2E232766E01D3803EB03D70128');
.
.
.

And I uploaded xml agent again
