> 1. Do you use "set pool=" anymore, now that the dedicated-cpu feature exists?
Until Oracle develops a more rational licensing scheme you should
expect this feature to be in use. I may have many Oracle instances,
each in a separate zone, using the same pool. The sampling on this
discussion list may not give you a good idea of its use. Might
pose this question on your blog as well ?
That said, this requires manual configuration of the pool. I don't
think it would be asking too much for customers using this feature
to also set up a boot time service (SMF or RC) to disable interrupts
on all CPUs in the pool. If needed (may not always be needed).
> 2. Is it sufficient to simply disable interrupts on a zone's pset?
I like your idea of turning off interrupts for dynamic resource pools
under zoneadm/rcapd control, and leaving it a configurable item. I
would also think that when CPUs are removed from the pool that
interrupts should be turned back on unless given to a another
pool with interrupts=disabled. I would hate for several zone
reboots to turn off interrupts to all CPUs :-(
