DBUA can ignore Underscores with "keepHiddenParams"

The Database Upgrade Assistant (DBUA) by default will remove all underscores and events before actually doing an upgrade. This is expected behaviour as we believe that underscores or events were meant to treat misbehaviour of the database just in a specific release only. And in our experience a nice collection of underscores will at least make your upgrades run slower.

Now with Oracle Database 11.2.0.4 and Oracle Database 12.1.0.1 the DBUA has a new parameter which can be used during startup:

$> dbua -keepHiddenParams

Then it will keep the hidden/underscore parameters during and after the upgrade.
