With the alert.log you are incorrect. Oracle only get a handle on the file when it
writes to it. The rest of the time, it does not need nor keep a handle on the
alert.log. You can move or delete the file and neither Oracle nor the OS care. A new
alert.log will be created as soon as Oracle needs to write to one.
