One of my dbf file is corrupted (Please see the attachment). So i have used below query to find the corrupted tables/indexes.
select owner, segment_name, segment_type
where file_id = 10 and
90 between block_id and block_id + blocks - 1;
This query output is no records.
After that i have used one more below mentioned query to find the objects in dbf file.
SELECT SEGMENT_TYPE,SEGMENT_NAME FROM V$DATAFILE V ,DBA_EXTENTS D WHERE
V.FILE#=D.FILE_ID AND NAME='E:\ORACLE\ORADATA\SFMS\SFMS_BRACH\SFMS_ARCH_NDX1.DBF';
The output of the below query returns no records.
I have used one more query to find corrupted file 10.
SELECT * FROM DBA_ROLLBACK_SEGS WHERE FILE_ID=10;
the output of the above query no records.
So finally i have decided recovery data till cancel (as per some google search),but i dnt have idea how to recovery till cancel method.
So please let me know how to correct my current issue. Also provide me step by step details of recovering data till cancel method. Other then this, if any other method you knows to correct my problem,please reply me ASAP.
I am not able to find this corrupted file 10 in datafile,segmentfile,tempfile.
