3 3 Benefits of Running Oracle on VMware

4 Why Deploy Oracle Databases on VMware? Oracle Licensing DB Consolidation Consolidate licensing Potentially Increase utilization of Oracle licenses (Depends on degree of consolidation) Reduce hardware costs by > 50% Consolidate servers by 4X 20X DB On Demand Provision databases on demand Minutes to provision in production and in the lab Quality of Service Increase application Quality of Service Scale dynamically Built-in high availability and simple disaster recovery Security Complete isolation between systems on the same host Protects databases and applications against network-based threats 4 4

5 VM Density Is Critical in Virtual Environment 1:1 1:1 1:1 Physical World 1:1 1:1 1:1 Many:1 Virtual World VM density matters! 1:1 relationship between applications and hardware Relevant cost metric = cost per server Many:1 relationship between applications and hardware Relevant cost metric = cost per application 5

6 Distributed Resource Scheduler Automatically balances load across ESX Clusters 6

7 VMware High Availability (HA) Protects VMs and automatically restarts VMs in the event of: Host failure VM failure (loss of heartbeat) 7

8 vsphere 4.1 and 5.0 App-Aware HA VMware HA VMware HA Resource Pool Resource Pool vsphere vsphere vsphere vsphere Protect against hardware failures Protect against app failures App-aware HA bridges the gap with app-level clustering Automated availability for both hardware and software failures Third-party agents detect application and operating system failures (for example, Symantec ApplicationHA) Invoke VMware HA through Application Health Monitoring API 8

9 vcenter Site Recovery Manager for Simple, Reliable DR VMware vcenter Site Recovery Manager complements vsphere to provide the simplest and most reliable disaster protection and site migration for Oracle Database and applications Site A (Primary) VMware Site Recovery vcenter Server Manager VMware vsphere Site B (Recovery) VMware Site Recovery vcenter Server Manager VMware vsphere Provide cost-efficient replication of applications to failover site Simplify management of recovery and migration plans Servers Servers Automate failover, failback, and migration processes for reliable recovery 9

21 Oracle Databases on VMware Key Benefits Rapid Provisioning 21

22 Accelerate Time-to-Market for Business-Critical Apps 3 Run more tests faster Test 4 Move changes into production Production 2 1 vapp Exact copy of production Archive for fast rollback vsphere vapp vsphere vsphere vapp Faster testing of multitier applications More accurate testing on exact production copy Lower cost testing infrastructure Reduce storage footprint by over 60% 22

23 Rapid Provisioning of Oracle Databases Provisioning Simple and rapid Use Golden Images to provide on-demand Oracle DB servers QA Dev/Test Reports DBAs can deploy Oracle DB server with no additional skills Ideal for Test and Dev Clone, transfer, and share environments easily, take system snapshots, or restore to previous state Automate SDLC with VMware vcloud Director Database virtual machine libraries Central repository of virtual machine images Virtual machine images with different DB and OS Storage leases help to reclaim space from expired images 23

24 Oracle Databases on VMware Key Benefits Compliance 24

25 Retention Periods Reproducing the Data and Audit Trail What if I need to reproduce a six year old legacy environment? Not as simple as locating the backup and recovering the database Need to recreate the entire hardware-software stack What OS? What application version? What database version? What patch level? On what hardware? If not, it is almost guaranteed transactions will not produce identical results Failed audit 25

26 Using vsphere for Compliance Purposes Cloning a fully virtualized database server captures the entire VM VM can be cloned and stored in a virtual vault/archive Then powered on in the event of an audit or discovery request Significantly simplifies environment regeneration process Hardware independent regeneration and recovery There is no single answer or magic solution to achieve compliance Capturing whatever solution suits a customer s environment in a VM is a powerful step towards compliance OS VMware vsphere 4.1 Clone OS 26

33 Oracle s Support Statement (Tech Note: ) 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. If a problem is a known Oracle issue, Oracle support will recommend the appropriate solution on the native OS. If that solution does not work in the VMware virtualized environment, the customer will be referred to VMware for support. When the customer can demonstrate that the Oracle solution does not work when running on the native OS, Oracle will resume support, including logging a bug with Oracle Development for investigation if required. If the problem is determined not to be a known Oracle issue, we will refer the customer to VMware for support. When the customer can demonstrate that the issue occurs when running on the native OS, Oracle will resume support, including logging a bug with Oracle Development for investigation if required. NOTE: Oracle has not certified any of its products on VMware. For Oracle RAC, Oracle will only accept Service Requests as described in this note on Oracle RAC and later releases. 33

34 How to Read Oracle s Support Statement Certification Oracle doesn t Certify Below OS Examples: Sun, HP, IBM, EMC, NetApp, Cisco, Dell, F5, Brocade, Intel, AMD Certification for VMware Not Required No changes to OS Support Known Issues Unknown Issues Rare Oracle Prefers Work Around Reproduce in Another Physical Env May Be Necessary Even W/O VMware RAC support Added on Nov 8 th 2010 Ask for List of Unknown Issues You Have Ever Experienced Contact Oracle Support (Not Sales) 34

35 Oracle on VMware is Better Supported Than Physical VMware will Own Your Oracle Support Issue For Known Issues VMware is Supported For Unknown Issues Option 1: Move Virtual To Physical Much Simpler than Physical To Physical Option 2: Switch VMware to OVM In-place reboot of Oracle using OVM in the Same HW No third-party license is required Option 3: Maintain Physical/Virtual using Dataguard Dataguard License is Required Many Customers Have Support Addendums 35

36 Oracle Licensing For VMware Example A VMware vsphere Distributed Resource Scheduler (DRS) cluster with Oracle 4 blades, each with 4 CPU cores and each virtual machine is 2 vcpu (2-core) vcenter Cluster 1 Oracle DB vmotion vcenter Cluster 2 Solution Both Oracle hosts must be licensed for all 8 cores on 2 blades Same for physical or virtual: (8 cores) x (0.5 x86 factor) = 4 licenses Free to move that Oracle database virtual machine to and from Host 1 and Host 2 Do not let Oracle Database virtual machines migrate to App Host 3 or App Host 4! Isolate VMware vcenter logical clusters, or DRS 4.1/5.0 host affinity rules See Gartner Research Doc ID #G for similar guidance 36
