RE: Datafile Corruption ........... or Not ------> Solved.

I really did not think you could recreate an object in the same tablespace once corrupted blocks were found .... I was wrong. It was a group of 20 indexes. Rachel told me offline to just drop and recreate the indexes. I did that and things worked just fine.

The only other time I had this problem was a table .... and it was rough to recover.

Thanks for everyones help.

Hi,

Find the corrupted object by the following statement:

Select segment_name, segment_type
from dba_extents
where file_id=<your_file#> and
<your_block#> between block_id and block_id + blocks -1

• If it's index, recreate it.
• If not, recover the datafile
• if no backup, tell us

regards...
