This used to be the case in Solaris 10, but in my experience Solaris 11 zones
are more like specialised chroot jails than VMWare-like virtual machines. All
running processes can be seen in the global zone. Perhaps AIX LPARs are
similar.. This is the reason that in Solaris 11, the zones and the global zone
(root zone) must always run the same version of the Solaris 11 software (no
rolling OS upgrades..). Solaris 10 is supported with a compatibility emulator
only, not with the actual Solaris 10 kernel.
I've installed Oracle in both Solaris 10 and native zones on Solaris11 , it is
quite straight-forward as you would expect.

Yes, each zone is it's own separate environment. There is a global zone as well

but the end result is very similar to VMware or other virtualized environments.
From within a zone you cannot see the other zones or even know they exist.
We are on Solaris 10 and have seen some weirdness where at low loads some
utilities such as uptime and sar show results for the zone only (as they
should) but under high load show results for the entire physical server. Don't
know if that's been fixed in Solaris 11 or not.

We're getting started on Solaris 11 and using zones and I'm not familiar with
installing Oracle inside a zone.
Is a zone basically a standard solaris installation running "virtualized"? In
other words, for each zone, do we setup the necessary limits and parameters using the
Solaris installation guide - pre-installation tasks? Or is that handled at the main
server layer and replicated down to the zones?
My initial reading suggests that each zone is a standalone operating system in a
"virtualized" environment but I'm not sure. (Also, is "virtualized" the right
term for a zone in this context?)
Thanks,
