RE: Database Verification

I would do all three. A good backup stategy is only good if you read all your data all the time. You can have corrupt data that doesn't get read and doesn't cause a problem for weeks, month, years. By that time you have no backup that does not contain corrupt data. Export to a null file to speed things up a little, just keep the log file. DBVerify is very useful.

Pui Ho,

   The only way you can be 'proactive' concerning corruption is to have a sound backup strategy - if you really feel nervous about your hardware, first change it, and then use archive logging and the rest; export is a bad solution, because it will be long to restore. By definition, a corruption doesn't give any warning (it's even worth than earthquakes). If you want to be very reactive, set something to regularly scan your alert.log file.
