6. Find the file and block using the above dba..
undef dba
select
dbms_utility.DATA_BLOCK_ADDRESS_FILE(&&dba)|| ', '||
dbms_utility.DATA_BLOCK_ADDRESS_BLOCK(&&dba)
from dual
/

Subject: From row to datafile
List - Does anyone know how to relate a database row to the datafile
where it is stored? Here is the situation: we are going to test the
recovery of a database, removing a few data files and then recovering
them from RMAN backup. These data files store image blobs out-of-line. I
would like to be able to list a few images from a particular data file
so after recovery we could retrieve those images. There are some queries
for dealing with database corruption where you can take a given file and
block and relate it back using dba_segments and sys.uet$. I 'm not sure
how to work for a specific row or with out-of-line blobs. Any ideas
appreciated.
