Step 3: Solve the issue

–in pfile add below lines into pfile
*.event=”10513 trace name context forever, level 2″ ## disable SMON recovery
*.event=”10231 trace name context forever, level 10″ ## skip corrupt blocks during select

–start your database from pfile

–After db up&running find corrupted blocks
select * from v$database_block_corruption;

–Also use this sql
COLUMN owner FORMAT A20
COLUMN segment_name FORMAT A30

SELECT DISTINCT owner, segment_name
FROM v$database_block_corruption dbc
JOIN dba_extents e ON dbc.file# = e.file_id AND dbc.block# BETWEEN e.block_id and e.block_id+e.blocks-1
ORDER BY 1,2;

Select * from dba_object where object_id=’xxx’;

–drop or truncate related  objects
drop index xxx

purge dba_recyclebin;
shu immediate
startup from spfile

–check database files via RMAN
RMAN> BACKUP VALIDATE CHECK LOGICAL DATABASE ARCHIVELOG ALL;

–Also use this sql
SQL->select * from v$database_block_corruption;
