MS SQL expert needs to learn Oracle

Hello,

I have been using MS SQL Server for about 8 years now. I am about to begin a new position at a company that uses Oracle as well. I would like to quickly get up to speed on Oracle. Can anyone here point me to any resources (online, books, training courses) that might get me started?

I don't need to learn the basics of database design or the SQL language. Mostly just the Oracle specific flavor of SQL, how to perform the various administrative tasks, different functionality in Oracle from SQL Server and of course and "gotchas" to look out for.

For any live training courses, I am in the Philadelphia area and would prefer not to travel to Timbuktu for a week. (ok, I'd actually love to travel to Timbuktu for a week, but I don't really have the time)

	Thanks!
