I'm not a DBA anymore...
Not from answering questions, but rather from being the DBA and semi-SA for the machine that was asktom.oracle.com.
Asktom.oracle.com is now synonymous with APEX.oracle.com - Joel Kallman facilitated the move (here is the story on that). So, I'm now running in a database with thousands of other applications. And - it seems a bit faster than my old hardware (which was held together with some glue and duct-tape - the drives were failing left and right...).
For some stories on APEX and the ability to handle a pretty large load - I suggest you glance at:
But now, for the first time in years, I won't be afraid to check asktom when I land and get off of the plane. If something goes wrong - the data center guys will fix it :)
And yes, the intermittent "some IE users get an error on asktom" issue was found and fixed.
