Oracle Database Discussions

Hey,

my table does contain 13000000 rows.

I do have a timestamp in this table (creationdate)

I want to delete entries older than x days.

Is there a way to delete rows step by step without manual interaction

delete from x where creationdate < '31.01.11'

< '28.02.11'

< '31.03.11'

...

Something with rownum ???

Also any way of preventig redo logs ?
