RE: Export table to determine extent of block corruption

Rhojel - I'm not sure if export gives you enough information. Usually the reason to export is that if you can export, you have a good copy of the data and you can breathe a little easier. But usually export will fail on the first corrupt block. Your corrupt block may be an index block, so export might succeed.
Doing a quick Google search yields

Metalink is another way to get some good advice for a problem like this. The last time I had this problem I saved Note 34371.1, but that may be obsolete now since it was about 5 years ago. But the horror seems like yesterday. Good luck. Now you've given me nightmares.

Hi Everyone!

This is my first time to encounter data block corruption in my entire DBA life(just 2 years FYI) =-)
(this is not something to be happy about but heck of an experience).
I'd like to know the extent of information that I can get from exporting that table that I believe has the corrupted block.. will I be able to know the absolute file# (AFN), relative file# (RFN), and the block# from the error that EXP will return>

Regards,
Rhojel
