On HP you have hard partitions (NPARS) (on rp8400, rp7410 and Superdome) and VPARS (virtual partitions) on any machine running 11i+ The VPARS do have some dynamic reconfigurables - the last time I used them which was just over a year ago you could reassign CPUs on the fly but playing with RAM required a reboot.
We used this technology to enable us to use one Superdome for both QA and DR. We had three hard partitions and split each of these into two VPARS. We could assign most CPUs and most of the RAM to the QA VPARS but if we needed to invoke DR then we could switch it over so that most of the resources were in the DR VPAR (this would of course require a reboot). A bit mind boggling but very cool and it worked flawlesly!
It's very weird have two sessions on two VPARS which are on the same machine (a machine without harware partioning like an N-class) and rebooting one partition in one session whilst Oracle runs flawlessly on the other!!!!
