Hi,
Two of the datafiles are experiencing data block corruption and recovery of the files not repairing the block corruption.

sql 'alter database datafile 2, 8 offline';
   restore datafile 2, 8;
   recover datafile 2, 8;
   sql 'alter database datafile 2, 8 online';



The media recovery finishes succesfully with no warnings.
But, after recovery when I try :

validate check logical datafile 8,2;



it shows again the block corruptions. I've tried recovery several times, and the same appears when I query V$database_block_corruption.
I also tried the same with
RMAN > Repair Failure
and the result is still the same.

I tried RMAN incremental and full after this and both of them failed

ORA-00600: internal error code, arguments: [17114], [0x2B58288E0BB8], [], [], [], [], [], []
ORA-00600: internal error code, arguments: [17147], [0x2B58288E0BB8], [], [], [], [], [], []




It seems the datafiles are not recovered and the block corruption exists after restore and recovery.

One of these datafile is from sysaux. and the DB version is 11g standard edition.

Talk to oracle support. This is a known bug.

Hi Mahesh,
Thanks for the info.

As an workaround; as RMAN backup is not possible, is it possible to build another DB will full expdp?
if yes, can you please shade some light on the steps can be followed to do the activity?

Thanks

Would be.
Nothing special here.
Just export and import (exp or expdp) like any other database ( hopefully there are no issues exporting it).
Just google for examples.

Hi Mahesh,

How about if I
1. Take SYSAUX and other corrupted datafile TBS export backup;
then
2. Drop the TBS
3. and import them on place.

will that help removing the block corruption?

Thanks.

a couple of points

1) DBV can identify the specific bad blocks within the datafile.
2) if you have the block number of a bad block you can determine which object, if any, uses that block
3) After knowing the object name, owner & type, in some cases that single object can be reconstructed manually.

4) AFAIK with V11 the SYSAUX tablespace is integral to the DBs operation.
5) do not believe you can remove all objects from it, drop it, & then rebuild SYSAUX

Hi BlackSwan,

I tried it but returned no rows. So I tried the following:

declare
nrows number;
badsegs number;
begin
badsegs:=0;
nrows:=0;
for i in (select file#,block# from v$database_block_corruption) loop
begin
insert into segment_corrupted select owner, segment_name, segment_type from 
dba_extents where file_id=i.file# and i.block# between block_id and block_id + 
blocks -1;
end;
nrows:=nrows+1;
end loop;
commit;
if nrows>0 then
dbms_output.put_line('List of segments affected by corruption');
end if;
for i in (select distinct owner, segment_name, segment_type from 
segment_corrupted) loop
dbms_output.put_line(i.segment_type||' '||i.owner||'.'||i.segment_name);
badsegs:=badsegs+1;
end loop;
dbms_output.put_line('Total blocks corrupted: '||to_char(nrows)||'. Total 
segments affected: '||to_char(badsegs));
end;
/

select * from segment_corrupted


And below is the output:

Hi Blackswan,

I attempted this earlier, but the problem is IOT.
it throws the following error:

ORA-28650: Primary index on an IOT cannot be rebuilt 


Thanks

URL above provides steps to remove & re-create SYSMAN schema.
I suspect this system has hardware or OS flaws & I would not trust it to run any Production DB

Thanks for the nice link. I'll try that on test and also
I agree with not executing the same in production.

Thanks for your continuous help.
