Oracle VM Blog: 64bit RAC is Now Certified!

I'm sure many of you are interested to know that 64bit Oracle RAC 10.2.0.4 is now certified on Oracle VM in addition to the previously cerrtified 32bit RAC.

As a result, the RAC-on-Oracle VM whitepaper has been updated to reflect this as well as generally updated to reflect the latest in best practices and configuration guidelines. The updated paper can be found here:
http://www.oracle.com/technology/products/database/clusterware/pdf/oracle_rac_in_oracle_vm_environments.pdf

Note that you can also navigate to it from the Oracle VM OTN whitepapers page here...

Some of the new content in the updated whitepaper:

  • Support for 64-bit Oracle RAC on Oracle VM

  • Support for CPU over-committing

  • Oracle RAC versus the OVM HA feature

  • Detailed VCPU allocation rules and examples

  • More info on supported storage for RAC in a OVM environment

  • Setting diagwait and how to prevent clock skewing

  • OCFS2 in the guest domain example
  •  

    RAC on Oracle VM is of high interest amongst our customers as they see it as a way to improve development and testing (create a multi-node RAC on a single physical server for development and functional verification), but also as a way to insulate the RAC nodes from the specifics of the underlying hardware to allow more flexibility for that hardware to change over time without requiring a change to the RAC configuration.

    Comments:

    What's happening with certifying other hypervisors for Oracle RAC, or any other Oracle product? right now it looks like we're being locked in to Oracle products only.

    Hi Ian, Thank you for your question! We do support several server virtualization and partitioning technologies with our database, not just Oracle VM. An overview of these is provided at: http://www.oracle.com/technology/products/database/clustering/certify/db_virtualization_support.pdf Regards, Adam
