Background
Running today’s non-critical business applications in
virtualized environments has shown to be efficient
and cost saving.
Oracle VM is the only software based virtualization solution that is fully supported and
certified for Oracle products.
Support Position for Oracle Products Running on VMware Virtualized Environments [ID 249212.1]
Oracle has not certified any of its products on VMware virtualized environments. Oracle Support
will assist customers running Oracle products on VMware in the following manner: Oracle will only
provide support for issues that either are known to occur on the native OS, or can be
demonstrated not to be as a result of running on VMware.

6
What is Virtualization?
It is a abstraction of computer hardware resources
Virtualization technology emulates
real — or physical — computing
resources, such as desktop
computers and servers, processors
and memory, storage systems,
networking, and individual
applications.
A hypervisor — also known as a
virtual machine manager
(VMM) — allows multiple “guest”
operating systems
to run concurrently on a single
physical host
computer.
Types
 Hardware Virtualization
 Full Software Virtualization
 Para virtualization
 Hardware-assisted
software virtualization
 Component or resource
virtualization

Server consolidation: A real-world example
100 Sun Fire V880 systems running
Oracle Solaris 8
17 Sun SPARC Enterprise T5240s systems
running Oracle Solaris 10
✓ Aggregate throughput performance would not change significantly for more workloads. In most cases, a single
T5240 can replace six V880s.
✓ Reduced space: 100 V880s require 50 data center racks, whereas 17 T5240s can fit in a single rack.
✓ Approximately 660,000 BTUs of heat generation would be removed from the data center.
✓ Approximately $200,000 would be saved in electricity costs per year (ignoring the cost of cooling).
✓ Acquisition costs for the new systems would be completely offset by the OPEX savings achieved in the first year.

Why run Oracle on Oracle VM?

19
Oracle VM Server Features
 High Availability: You can configure resources to restart the guests on another host if the underlying host fails.
 Live Migration: You can relocate the guests from one host to another with no loss of service.
 Load Balancing: If configured, Oracle VM automatically load balances upon guests startup
 Performance: Xen hypervisor is among the fastest forms of virtualization.
 Rapid Provisioning: Through the use of cloning and virtual machine templates, Oracle VM can quickly and
efficiently create new guest operating system.
 VM Templates: Oracle provides wide-range of preconfigured virtual machine templates.

20

24
Live Migration topics
• Guest memory contents are copied over the network from the source system to the
target while the guest continues to run
• Guest virtual machine is "suspended" for a brief period of time
• Migration times vary
• Allocate sufficient CPU resources to the control domain
• Use a fast and otherwise low-utilization network segment.
• Try to reduce the virtual machine's memory size
• Not a substitute for fault resiliency or high availability technology - you cannot live
migrate a virtual machine from a server that isn't alive

25
Advanced Policy Management of VMs
Modify for Live Migration
Dynamic Resource Scheduling (DRS)
• Live Migrate VMs based on server load
• Dynamically managed quality of service
H.A. Auto-restart
• Automatically restart VMs on failed servers

Storage Live Migration
• Support for Live Migrations of running virtual machines that have virtual disks on
local storage (Local to Local SLM)
• Built into the OCFS2 file system on x86 platforms to achieve nearly uninterrupted
uptime for virtual machines
• Note - Separate your server pool file system and your cluster heartbeat file
system – If not, SLM can disrupt the cluster heartbeat function
• Note - Configure separate channels for live migration network traffic and other
network functions such as cluster heartbeat
High Availability / Disaster Recovery

27
Cloning, Snapshot & Ksplice
• Oracle VM allows cloning of virtual machines and templates to create new copies
which can then be backed up or customized:
• Cold clone – in this case the virtual machine is completely stopped. This choice offers widest number of
supported conditions.
• Hot clone – in this case the virtual machine is running. This choice is only supported for Oracle VM Guests
with no running databases and must reside on virtual disks within an OCFS2 formatted storage repository
(OCFS2 Reflink)
• Storage snapshot
• Ksplice technology – Oracle VM to support hitless kernel updates
