Disabling SKIP_CORRUPT after using DBMS_REPAIR.SKIP_CORRUPT_BLOCKS
You can disable it with the same procedure.

begin
  dbms_repair.skip_corrupt_blocks
  (
    schema_name =&gt; '...',
    object_name =&gt; '...',
    object_type =&gt; dbms_repair.table_object,
    flags=&gt; dbms_repair.noskip_flag
  );
end;
/


dbms_repair.skip_flag enables, dbms_repair.noskip_flag disables this behaviour.
