I didn't want to open an SR just for this question. For downtime scheduling purposes -- Upgrading from Oracle 10.1.0.2, or 10.1.0.4 to 10.2.0.4 (on Solaris 5.10, (or any OS)): Does the time it takes to upgrade significantly change depending on the size of the database? e.g. Will a 200Gb database upgrade in essentially the same time window as a 20Gb database?
