Thanks for all the tips so far. Yes I am gathering dictionary stats and
fixed object stats right before.
Here is the output summary. I test the memory setting and processes.
And Tim I'll look for an AWR.

I have been upgrading our multiple 10g databases to 12.2 or a while now.
Here are the few things that I have come to make sure of on each upgrade:
1. Gather Dictionary and Fixed Object Stats before hand. Makes a
difference
2. 12 seems to take considerable more memory than 10 did. I have had
to raise up SGA and PGA values considerably.
3. Processes had to be raised . It seemed that the upgrades were
slower at lower processes setting
4. Larger rollbacks with more groups. I used to have 4 groups with
relatively small files in them but when I changed that to 10 groups with
larger files the upgrades sped up
Some of these suggestions may not be thought of as being something that
would cause a faster upgrade, but it did it on our setup so I leave it to
you to consider or not.

I am working on upgrading a database from 11.2.0.4 to 12.2.0.1. Single
instance non CDB. The upgrade is taking 2 hours and 50 minutes. I am
running the command line version of the upgrade and using parallel. Any
tips to make this go faster? I already have APEX 18.1 installed however I
am noticing it is becoming invalid during the upgrade and I have to
reinstall it afterwards.
Thanks
