Podpora pre Oracle nad VMware platformou

Oracle Support for VMware Virtualization

Oracle Support has been forthright about its stance toward VMware virtualization for over four years. Oracle has a support statement for VMware products and it is honored around the world. While there has been much public discussion about Oracle’s perceived position on support for VMware virtualization, VMware’s experience is that Oracle Support upholds its commitment to customers, including those using VMware virtualization to work in conjunction with Oracle products.
VMware is also an Oracle customer; our E-Business Suite and Siebel instances are virtualized; and VMware routinely submits and receives assistance with issues for Oracle running on VMware virtual infrastructure. The specifics of Oracle’s support commitment to VMware is provided by the MyOracleSupport Metalink document ID #249212.1. While prohibited from reproducing the document, we can highlight a few of the facts that Oracle Support has maintained with regard to this statement for the four-plus years of its existence:

Known issues: Oracle Support will accept customer support requests for Oracle products running on VMware virtual infrastructure if the reported problem was already known to Oracle. This is crucial! If you are running 9i, 10g, or other products with a long history, the odds are in your favor that if you find a problem, Oracle has seen it before. If they’ve already seen it, they will accept it.

New issues: Oracle Support reserves the right to ask customers to prove that “new issues” attributed to Oracle are not a result of an application being virtualized. We say―fair enough―this is essentially the same as every other ISV, to one degree or another. What is key is to look at the history of Oracle Support with regard to “new issues.”

From the perspective of MyOracleSupport, in four-plus years of tracking VMware-related issues, you will find essentially no bugs attributed to VMware ESX or vSphere with Oracle.

VMware routinely asks reference customers from around the world to share their success stories regarding submission of issues to Oracle and getting appropriate and helpful responses. As noted above, Oracle Support routinely provides support to customers running on VMware virtual infrastructure world-wide.

Oracle RAC: Oracle RAC today is “expressly not supported.” Oracle has made it clear that while it is legal to run RAC on VMware infrastructure, they are under no obligation to support it. Yet, even still, we have many customers running RAC on VMware infrastructure; it works fine, and even these customers have been able to submit issues to Oracle for resolution.

Certification: VMware vSphere is a technology that lives under the certified Oracle stack (unlike other virtualization technologies that alter OS and other elements of the stack). As a result, Oracle cannot certify VMware virtual infrastructure. However, VMware is no different in this regard than an x86 server—Oracle also doesn’t certify Dell, HP, IBM, or Sun x86 servers.
VMware recommends that customers think logically about Oracle’s support position. Test the hypothesis presented above. Begin with pre-production systems; as issues are encountered and SRs are filed, track Oracle’s response. VMware’s experience is that customers will see no difference in the quality and timeliness of Oracle Support’s response.
