Upgrade mit underscores Parametern

Normal wird beim Upgrade alle underscores Parametern gelöscht. Dies kann nun seit geändert werden.

Hier habe ich das gefunden:

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 and Oracle Database 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.
