Thanks Dennis! I've read a couple of docs on getting enough information on the corruption.
I'd like to use DBMS_REPAIR.CHECK_OBJECT, but I'd like to know first if this would be "safe"
to run on an online production database. Could anyone comment on this?
Oh Dennis, sorry for the nightmares ;-)

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

<http://www.quest-pipelines.com/newsletter-v4/0103_C.htm> . I haven't read
it in detail, so I can't vouch for its accuracy. 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
