My Experiences with Oracle Cloud and Oracle VM technology   9 comments

It was a great honor for me to recieve the  industry prestigeous award “2012 Oracle Excellence Award: Technologist of the Year for Cloud Architect  ”  from Oracle Mazgine. Although I received this award at Oracle OpenWorld 2012 in San Francisco in early Octorber 2012, the award was officially announced on the  Oracle Magzine’s January/Feburary 2013 issue . im08t0-awards-tech-yu-1875816 - Copy

My original backgroud was Oracle DBA and Oracle Applications DBA. My experiences was mainly  on managing large Oracle RAC databases and Oracle E-Business applications suite running on complex muitple nodes environment such an Oracle Grid.  In late 2008, as a part of addtional responsibilites of  my job, I  started  working on Oracle virtualization technology  specifically   Oracle VM  for X86-64 platform .  Since then Oracle VM has become of one of my favour technologies. Natually I started looking at the best practices of running and deployment Oracle RAC databas, Oracle E-Business  suite applications on the Oracle VM enviroment.  The Oracle OpenWorld 2009 confernece allowed me to give three presentation sessions about  my work on Oracle VM technology:

And the contents of these presentations were also published in three whitepapers:

In 2010, Oracle Introduced the Oracle E-Business Oracle VM template. I was working on  a  project  for which I needed  to  deploy Oracle E-Business Applications on Oracle VM environment . However I noticed that the Oracle EBS VM template downloaded from Oracle was a general template for the Oracle EBS vision instance. For the project, I needed to find out a way to virtualize the exisiting  production Oracle E-Business suite system that currently ran on the physical environment . That is the backround that I came up the solution to  migrate the Oracle EBS suite t to a virtual environment. As a result of the project, I put toegther a whitepaper about this solution:

and also presented this solution at several Oracle conferences:

I also worked on provisioning database and applications using Oracle Enterprise Manager’s Software library and provisioning procedures  It can be considerred the early version of Oracle Cloud application provioning methods. Built in with Oracle Enterprise Grid control 10g, this  method can  quickly provision multiple node Oracle 10g RAC . Some of the early projects were presented at Oracle OpenWorld and Collaborate conferences:

As a  part of Oracle Enetrprise Manager 12c cloud beta efforts, I worked with Oracle EM12c product engineers and product managers on a Dell | Oracle joint Oracle cloud project. This project aimed to architect and implement a privare cloud solution based on Oracle VM and managed by Oracle Enterprise Manager 12c.  By importing Oracle VM templates into the Oracle Enterprise Manager 12c’s software library, on this project we were able to  implement  the self service provisioning of applications  in the Oracle cloud environment using Oracle VM templates. The result of this project was presented at Oracle OpenWorld 2011, right after Oracle officially announced Oracle Enetrprise Manager 12c, total cloud control solution. 

In 2012, as Oracle released new version of Oracle VM 3.0, we upgraded this cloud  to Oracle VM 3.1.1 and implemented the self provisioning multiple tier applications   using Oracle virtual assembilies. the newer version of Oracle cloud was presentated at Oracle Openworld 2012:

Another area I have worked on is the Oracle database cloud based on Oracle RAC technology with or without Oracle VM:

These are some of presentations that  I have given on this area:

  1. Great work Kai…Kai the unstoppable, I would require atleast next 5 years to download and learn little bit on what is explained on the papers.

    • Hi, Ajith,

      Thank you for your comments. Believe me with your technical background, you should be able to pick up these technologies very quickly. Let me know if you need any further information. Thank you!
      Kai

  2. Congrats Kai for award ,you deserve it 🙂

  3. I like the helpful info you provide in your articles.
    I’ll bookmark your blog and check again here frequently. I’m quite sure I will
    learn plenty of new stuff right here! Good luck for
    the next!

    • Thank you for the feedbacks. I am very happy to hear that you found the information helpful.
      your feedbacks definitely motivate me to continue. Please come back to visit frequently. I should be
      adding some new contents including the new 12c database and 12c RAC once Oracle officially releases it.

  4. Hi Kai,

    Great blog and information provided.
    I wanted to ask if you would share your experience and general approach when upgrading and patching RAC nodes running as OVM guests. Once templates deployed and RAC nodes are up and running, do you threat them as any other (non-virtualized) Oracle RAC environments by patching OS, clusterware, Oracle installation, database? or maybe using Oracle EM Grid for mass-patching but still threat them as any other non-virtualized Oracle RAC from patching perspective?

    Thank you.

    • Hi, Milan,

      Thank you for visiting my blog and your comments. Yes, you are right. Once you deploy the Oracle RAC on VM, the management and upgrade and patcing processes are very similar to those running on physical (non-virtualized) servers. You can use add the host and the databases as the targets in Oracle EM and do the mass-patching. The only difference is that when you need to add storage or make any change on the network, you need to prepare the storage and network on hyperviser (VM server) level first, then expose them in the VM level before you can use them for the RAC on the VMs.

      Hope these answer you questions. Let me kno wif you have any addtional questions.

      Thanks
      Kai

  5. Hi Kai,

    Your reply perfectly answered my questions.
    Thank you very much for your time.

    Regards,
    Milan
