Agenda • What is Virtualization? • What is Oracle VM ? • Why run Oracle on Oracle VM? • Oracle VM Templates for Oracle Database • Stay Connected
4 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.
5 What is Virtualization?
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 Virtualization players in market
7 Reasons for Virtualization? Server Consolidation Server Provisioning Backup/Restore Hosting/ Cloud Computing
8 Types of Hypervisors Oracle VM VMware vSphere KVM Xen Hyper-V VirtualBox VMware Fusion VMware Player VMware Workstation Guest OS Guest OS Guest OS Server Hypervisor Type 1 – Native (Bare metal) Guest OS Guest OS Guest OS Operating System Hypervisor Server Type 2 – Hosted
9 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. =
10 What is Oracle VM?

18 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 Why Virtualize with Oracle? Oracle VM Templates to shorten time to market Oracle Enterprise Manager provides complete VM and cloud lifecycle management. Rapid deployment with 100+ Oracle VM Templates Oracle Virtualization from applications to disk.
21 Oracle VM Templates Easier...Faster...Lower Cost...Fully Supported for Production Deployments • Rapid Deployment • 100+ Templates • Pre-built, pre-configured, production-ready VMs • Apps, Databases, Middleware, OS; Siebel CRM, Oracle RAC, More… • Near zero knowledge of OS, Application installation required • Automate deployment of a complete production ready 8 node RAC cluster in minutes through a simple single configuration file
22 Oracle VM Templates / Virtual Appliances Rapid Application Deployment Recent Updates: • Oracle Database – deploycluster supported on Oracle VM 3.3 •E-Business Suite • JD Edwards •PeopleSoft • etc. Start-Up in Oracle VM Pool VM 1 RAC VM 2 RAC VM NAS, SAN, iSCSI Oracle VM Servers Oracle VM Server Pool VM VM Software Delivery Cloud Download from Oracle •Pre-built, pre-configured VM •Complete Single Instance OR Clusterware, ASM, RAC installation (11gR2 or 12c) or other applications Import to Oracle VM Manager File DB/ RAC VM Customize & Save as Golden Images VM Save days or weeks in installation and configuration time VM SI
23 Oracle VM Manager - Live Migration & HA/Auto Restart Cluster VM VM VM VM Oracle VM Servers NFS, SAN, iSCSI Cluster VM VM VM VM Oracle VM Servers NFS, SAN, iSCSI Clustered Manager Browser XE, SE, EE, or RAC Database Planned Events: •E.g. maintenance or upgrades •Secure Live Migration •Zero interruption SSL Migration X Unplanned Events •E.g. Serveror VM failure •HA Auto-restart in pool •No manual intervention X HA Auto Restart mm Pool Masters assure Secure Migration or HA restarts complete in the event of a Manageroutage HA / Auto-restartLive Migration
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 Dynamic Power Management (DPM) • Automatically power-off under-utilized servers Server Pool 1 Server Pool 1 Utilization Consumption 25
26 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

    4 Background Running today’s non-criticalbusiness 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? Itis 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 Virtualization players in market

    9 Server consolidation: Areal-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. =

  • 24.
    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.
    25 Advanced Policy Managementof 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 Dynamic Power Management (DPM) • Automatically power-off under-utilized servers Server Pool 1 Server Pool 1 Utilization Consumption 25
  • 26.
    26 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.
    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
