Irrelevant thoughts of an oracle DBA

oracle unbreakable linux with Wim Coekaerts

Filed under: linux,Oracle VM — Freek D'Hooge @ 0:26

Today we had an Oracle partner meeting with Wim Coekaerts.
For those who don’t know who Wim Coekaerts is, he is vice president of Linux Engineering for Oracle (and originating from Belgium, but living in the US for more then 10 years now) and is also known as Oracle’s Mr. Linux.
Needless to say that when I received an inventation to attend a partner meeting with him, I was quickly to confirm my presence.

The presentation that Wim gave was divided into 2 parts: Oracle unbreakable linux and Oracle VM. Both parts where very interesting and at the end we had more then enough time to ask questions.

Some key points that I have written down:

Enterprise linux:
  • Oracle did not launched oracle enterprise linux to bully Redhat or to push Redhat out of the market.
    They came with their own linux support because they felt that oracle customers where not helped sufficiently by Redhat support. As oracle software can be freely downloaded for testing and this is not possible with Redhat linux, oracle came with an own rebuild.
  • Oracle Enterprise linux is not a separate fork and never will be. It is, and stays completely compatible with Redhat linux.
    In fact, when oracle tests its software, they don’t differentiate between Oracle Enterprise linux and Redhat linux as os platform.
  • Oracle did not include an option to the installer to provide it with “preset” options suited to host an oracle database (needed rpm’s, kernel parameters, …), because they did not want to create the appearance that they are creating a fork.
    Instead oracle created the “oracle validated configuration” rpm. When installing this rpm, it will also install all rpm’s necessary, creates the oracle user and sets the kernel parameters and user os limites.
  • Linux (32bit) is the reference platform for all development.
    It is also the platform for all internal servers.
Oracle VM:
  • Wim claimed (and a paper about this would be appearing soon) that an oracle database running in oracle VM will perform at about 90% compared to running it on a real server. With VMware this would only be 70%.
  • You no longer have to license your database for all physical processors on the oracle VM server, but only the number of cpu’s defined in the guest.
    According to Wim there should be a document about this on the oracle site, but the document I found stated that this was only true when using hard partitioning with Oracle VM (
    I will check this further.
  • The license policy for oracle on vmware was not going to change.
  • Grid control 11g will have buildin functionality to manage Oracle VM servers (deploying guests, performing life migrations, …), but the VM-Manager will not disappear.
  • The oracle supplied guest images will be certified for production use somewhere during the second half of this year.
    This would mean that you could download a database image from the oracle site and use it as a production database.

That was about it.
After the presentation I felt more assured that OEL would be here to stay and that the compatibility between Redhat linux and OEL would not disappear in the future.
Not to sure about Oracle VM though, I’m still a little bit anxious of running production databases in a virtualized environment (according to my shrink I have a problem with losing control).

  1. […] father of the whole linux story within Oracle. I agree completely with what Freek already posted in his blog (he attended as well). On top of that I want to add some personal thoughts as […]
