I might have missed something but, in Oracle, is there no concept of AUTO_INCREMENT? If there isn't, is there a way to create a column that resembles AUTO_INCREMENT in Oracle 11g?

It doesn’t exist out-of-the-box in Oracle.  You have to create a ‘normal’ numeric column, and create a BEFORE INSERT trigger to provide the incremented value at insert time. You would usually use a SEQUENCE to generate the values, but that is not mandatory.
