For those who are familiar with Tom Kyte and his site Ask Tom, this is now running on apex.oracle.com. Don't believe me? Then compare http://asktom.oracle.com and http://apex.oracle.com/pls/otn/f?p=100:1.
This turned out to be a fairly painless exercise. I actually moved the application about 4 months ago, created the workspace, created the ASKTOM database user, did an initial database import of his database objects and data, imported his application, changed all of the references to images and CSS's in a custom /i/asktom_i directory to be Shared Components of the application, and then worked with Global IT to setup the proper definition of this new Virtual Host and other Web Server configuration. Then it was just a simple matter of timing, to coordinate the DNS switch (which Global IT handled) and the Data Pump export and import (which Tom handled - I tried to think of someone more qualified and could not).
The switch from the old server to the new application on apex.oracle.com happened yesterday at 16:48P EDT (GMT - 04:00). Since then, roughly 16 hours ago, we've had 24,701 page views on the AskTom application. And Tom went so far as to describe the performance as "snappy".
I warned Tom that there is an ongoing issue with some users and the network performance to apex.oracle.com, and that the new AskTom would be inheriting this issue, but so far, no issues have been reported. And for the person who will undoubtedly call me out and say "apex.oracle.com is not intended for production applications", that is a correct statement - if you're not ProMED or AskTom and you don't work in my group, consider it only your playground and demonstration instance.
