I'd like to do some block media recovery testing in RMAN. It seems that the
Linux/Unix "dd" command would be an obvious choice to corrupt an Oracle
datafile block, but has anyone documented a controlled test like this? Try
to not reinvent the wheel, if possible.
I'm thinking of targeting specific objects in the database to corrupt. It
doesn't seem difficult to get a relative block and "dd" an empty block in its
place on a test instance, but if someone's already beaten this path...
