ORA-01578 error

Question

Hi,
I was trying to collect schema stats. The system occurred with ORA-01578 error.
ORA-01110: data file 7: 'M:\ORADATA\PRODORCL\DATAMDM01.DBF'
ORA-26040: Data block was loaded using the NOLOGGING option
ORA-06512: at "SYS.DBMS_STATS", line 12887
ORA-06512: at "SYS.DBMS_STATS", line 13213
ORA-06512: at "SYS.DBMS_STATS", line 13289
ORA-06512: at "SYS.DBMS_STATS", line 13249
ORA-06512: at line 2
I was trying to do:
SELECT TO_CHAR(SYSDATE, 'DD-MON-YYYY HH24:MI:SS') FROM DUAL;
begin
dbms_stats.gather_schema_stats(ownname=>'DBA',estimate_percent => 10,method_opt=>'FOR ALL COLUMNS SIZE 1',cascade=> true);
end;
Thanks

I do understand, but I have dealt with block corruption. Can you please tell me how to fix this.
I have gone through couple of documents and tried:
set serveroutput on
declare corr_count binary_integer;
begin
corr_count := 0;
dbms_repair.CHECK_OBJECT (
schema_name => 'DBA',
object_name => 'INVENTORY',
partition_name => null,
object_type => dbms_repair.table_object,
repair_table_name => 'REPAIR_TEST',
flags => null,
relative_fno => null,
block_start => null,
block_end => null,
corrupt_count => corr_count
dbms_output.put_line(to_char(corr_count));
end;
it shows :
6226
but when I do:
set serveroutput on
declare fix_count binary_integer;
BEGIN
fix_count := 0;
dbms_repair.FIX_CORRUPT_BLOCKS (
schema_name => 'DBA',
object_name => 'INVENTORY',
partition_name => null,
object_type => dbms_repair.table_object,
repair_table_name => 'REPAIR_TEST',
flags => null,
fix_count => fix_count
dbms_output.put_line(to_char(fix_count));
END;
it shows:
0
but it should be show the same 6226.
Can you please tell or provide doc for fixing this?
