ANALYZE ... VALIDATE INDEX will put a shared lock on the table preventing
DML.
Unless you are using 9i or later, when you can use the ONLINE option.
Impact: it depends.

Subject: Validate index
Hi All,
Does validate index (pk index) enforce any exclusive lock on the table?
The reason I am asking is that we are trying to validate few indexes(to find
out fregmentation) on production (while the site is live). What could be the
impact on parent table?
Thanks
Sami
