Hi all,Solaris Zones are more similar to AIX WPARs.Using Solaris Zones you create virtual servers at the kernel level so basically you have one Solaris per physical server with several virtual Solaris servers.If you use e.g. Sparc server you can physically partition server and install separated Solaris in each partition (and then of course if you wish createseveral virtual servers called Solaris Zones :-) ).RegardsPrzemekOd: "De DBA" <dedba_at_tpg.com.au>Do: oracle-l_at_freelists.org; Wysłane: 9:42 Środa 2014-07-09Temat: Re: Sun Servers
Containers, zones and partitioning are used interchangeably but do
not necessarily refer to the same thing. I think it is important to
realise that machine partitioning into separate domains is (on Sun
boxes) done at the OpenBoot level, not in the OS. The Solaris zones
(in Solaris11) are merely logically separated process spaces. This
can be seen in the root zone, where all running processes including
those in zones are listed by tools such as ps(1). I believe that
Solaris Zones are comparable to AIX LPARs, at least in this respect.
In OEL you could use the OVM/Xen kernel for this purpose.
As far as I am aware (correct me if I'm wrong) when the machine is
partitioned, resources such as CPU and memory cannot be shared
between domains. When using logical partitions, a.k.a. zones, the OS
resources can be pooled and shared between zones.
The ability to partition a machine may be an advantage, depending on
your intended use. I've never seen it implemented.

Thanks Mark.
That sounds pretty cool.
One of the big selling points I got from Oracle was
the ability to partition machines.

Ronan,
we have
deployed a couple of X4-2L for a customer
- environment is 11.2.0.4 on Solaris 11.1
x86_64. I have been very impressed with
what the Solaris 11.1/Zones/ZFS
combination provides. We have the database
servers on the X4-2L mounting a ZFS
storage server over dNFS via a 10G and 1G
combiation. The X4-2L have been
provisioned with 4xF80 flash cards in them
as well that have allowed us to allocate
specific flash devices to different zones
as required. It is a very powerful and
flexible platform to deploy databases and
application servers on.

Mark

Thanks for replying Jack.
Pretty much the same move I am looking at -
Dell/Red Hat to Sun/OEL.
They will be standalone servers though not
ODA's.

We've moved all our 20+ databases from RedHat
Linux Dell servers to two new X4-2 ODAs -
Oracle Linux on Sun servers. We're happy so
far. The ODA environment is a lot more
restrictive than just a standalone server.
However, it is simpler.

Thanks Andrew.
I'll keep that in mind.
Factory install of Oracle Linux is an
option. I did all my OCP practicing and
testing on Oracle Linux and I liked it.
