Re:How does one manually corrupt a database (database file, redo logs and backups)

I believe a simple way to corrupt an oracle datafile, redolog, controlfile 
could be:

echo "<somewhat string>" >> oracle_file

This should alter the file offset (I don't know if this is the correct 
technical term) for every binary file and thus making it corrupted towards and 
Oracle db.
The command should also work for both unix and windows.

Alessandro
