How to do it with Oracle SQL Developer: In the Left pane, under the connections you will find "Sequences", right click and select create a new sequence from the context sensitive pop up. Fill out the details: Schema name, sequence_name, properties(start with value, min value, max value, increment value etc.) and click ok. Assuming that you have a table with a key that uses this auto_increment, while inserting in this table just give "your_sequence_name.nextval" in the field that utilizes this property. I guess this should help! :)
