What are the remaining issues with Oracle?

I'm going to finish running up an RT dev environment on my Mac tonight. 
Hopefully I'll have a good weekend of RT/Oracle hacking ahead of me. My 
institution runs on Oracle so RT isn't an option for a wider audience 
without full Oracle support.

What other Oracle tips/problems can people suggest?

This is what RT currently does under MySQL so I am guessing that it should 
be the same behaviour under Oracle. So for a search result of 10 the pages 
displayed will be: 1 - 10, 10 - 19, 19 - 28. Which is also the numeric 
count at the bottom of the Search/Listing.html page.

count(*) will only return ONLY ONE ROW - ever. Unless that count(*) query 
also has a group by clause. Since SearchBuilder doesn't use group by in its 
_DoCount then the removal of ApplyLimits for every database is a good thing.
