I'm doing a direct upgrade from 11.5.9.CU2 to R12 (probably CU3). I got to the point where the db objects are upgraded and received the following message:
There are now 126521 jobs remaining (current phase=A3):OK, then. When I upgraded from 11.5.3 to 11.5.9, the object upgrade portion took about 26 hours, but I was on a slower box (Sun 2x900 with 8G RAM) and Oracle 22.214.171.124. Now I'm on a Sun 4x1200 with 16G of RAM and Oracle 10.2.0.3. This is only my first attempt at upgrading and I'll look at the AWR stats after to see where my bottlenecks were during the upgrade.
6 running, 951 ready to run and 125564 waiting
Any guesses on how long this upgrade run will take?
