And almost any Oracle application programmer can write a bad query that will
get Oracle to eat an IFL.
With better application choices, tens, hundreds of Linux images can run
nicely on an IFL under z/VM. But if your customers only want to run a
handful of Linux images and can accept the LPAR management (cannot quite
define a new LPAR as fast as defining a new virtual machine), then LPARs are
my recommendation.
...and you can define LPARs in advance, more than you need now. It does
not consume any CPU cycle, however it takes memory. I'm not sure about
dynamic memory re-allocations - in general it is feasible, but don't
know details.
