There are a lot of new Advisors.  I also beleive Automatic Memory Management was new in 10g.

The New Features doc is the best place to start:
http://docs.oracle.com/cd/B19306_01/server.102/b14214/chapter1.htm

In that doc be sure to check out: Automatic SQL Tuning.

About which?

Everything is in the docs.  Just use the doc search for those terms.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Regretfully perhaps, but it's time to RTFM as recommended.  Two factoids I found useful were that the CHOOSE hint was dropped as the CBO default; and that STATSPACK was replaced with the automated workload repository (AWR). E-E and Metalink also have tons of previously asked questions about tuning.  HTH

SQL Profiles is a new feature from 10g which is managed by Oracle Enterprise Manager as part of the Automatic SQL Tuning process. Apart from OEM, SQL Profiles can be managed through the DBMS_SQLTUNE package
