Needs help regarding block corruption

Question

DB Version - 11.2.0.3.0
Issue - Last backup failed due to block corruption ,message says "ORA-19566: exceeded limit of 0 corrupt blocks for file /GP/GAA01-N-P/db00/index01/GPEDWPR/bi_gpedw_fcct.dbf'
I tried to perform block recovery using RMAN but it was not present in backup, hence failed. tried in the below way also :-
RMAN> LIST FAILURE
2> ;
using target database control file instead of recovery catalog

Now how to troubleshoot ? Any help will be highly appreciated

Answer 1

First, you need to determine to which segment the block is assigned:
select segment_type,owner,segment_name
from dba_extents
where file_id=58 and 3106752 between block_id and (blockid + blocks -1);
Your action from there will depend on the type of segment. Since you have no backup, the options are limited. But there are still possibilities.
