Re: How to remove corrupted blocks from datafile.

Did you check your disk to make sure that's not where the corruption started. There maybe some physical disk problem or file system problem. If you have some bad blocks on your disk you need to fix them first.

Hi,
I found some corrupted blocks in one of the datafile. I have created the temp table by select all the records (excluding the records in corrupted blocks) from corrupted table, and dropped the table, renamed the temp table back to original. After this when i run DBV on that file, it still shows there are some corrupted blocks in the file. i have two questions,

1> How do i calculate how many records i have lost? 2> How do i remove corrupted blocks from the blocks?

Can anyone tell me ...
Thanks in advance
Uday
