Perfect. !!!
In order to save some time you can update the statistics of sys schema
before hand. So that it doesn't do it in between the upgrade.

Funny you should ask. I just (3:05pm to 3:30pm EST) ungraded a
10.2.0.4.3 database to 11.1.0.7.0 that was about 15GB. And, now i'm
about to upgrade a 171GB database. I'll mail the list with the timing.
I would guess that 10.1 to 10.2 would be even quicker then what i'm
doing.

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?
