Hello Don
It is much easier to use seg/obj. Convert 1441f to decimal and it is 82975.
seg/obj: 0x1441f csc: 0x06.8098c3ed itc: 10 flg: E typ: 1 - DATA
select owner, object_name, object_type, subobject_name from dba_objects
where data_object_id=82975 or object_id=82975;
You can also use dba :
Block header dump: 0x0404ead5
converting 0x0404ead5 to decimal : 67431125
1 select
2 dbms_utility.DATA_BLOCK_ADDRESS_FILE(&&dba)||','||
3 dbms_utility.DATA_BLOCK_ADDRESS_BLOCK(&&dba)
4* from dual
/
DBMS_UTILITY.DATA_BLOCK_ADDRESS_FILE(67431125)||','||DBMS_UTILITY.DATA_BLOCK_ADD
