Virtualizing Oracle eBS installed in Oracle VM Server

  • 1.  Virtualizing Oracle eBS installed in Oracle VM Server

    I'm planning to test virtualizing Oracle eBS 12.1.3 using Delphix 4.2 engine. My test source eBS installation is using Oracle VM Server as an host environment like in the graphics below.

    Source of the graphics: http://docs.oracle.com/cd/E16538_01/ovm/acrobat/EBusinessSuiteOVMDeploymentGuide.pdf

    I found in Delphix documentation (http://docs.delphix.com/display/DOCS42/Supported+EBS+Versions" href="http://docs.delphix.com/display/DOCS42/Supported+EBS+Versions">http://docs.delphix.com/display/DOCS42/Supported+EBS+Versions) following note:
    https://d2r1vs3d9006ap.cloudfront.net/s3_images/1181133/RackMultipart20150331-32630-a55x3m-ScreenHunter_931_Mar._31_11.12_inline.jpg?1427793144" src="https://higherlogicdownload.s3.amazonaws.com/DELPHIX/UploadedImages/88b75a67aa0e4db6ae69d40cb38434ca_RackMultipart20150331-32630-a55x3m-ScreenHunter_931_Mar._31_11.12_inline.jpg">
    Does it mean that it is useless to start such experiment because it won't work at all?
    How should I understand this note?

    Piotr,
    The note refers to provisioning a virtual EBS instance from an EBS instance that has already been virtualized in Delphix (i.e. a Copy of a Copy). Delphix doesn't care whether an operating system runs on virtual hardware or physical.

    I've got it now. This is good news. Thanks for clarification.

    Piotr,

    There's additional complexity in provisioning from a virtual EBS instance (i.e. making a copy from a copy) that Delphix does not handle today, but the UI does not prevent one from doing so.

    We do not recommend provisioning from virtual EBS instances at this time.  In future, this limitation might be lifted.

    I have some questions related to my EBS cloning tests. This is DE 4.2.1.0.

    (1)
    I have prepared target hosts as OEL6.4 VMs. When I register such VM instance as an environment I get following error message

    I tried to find information about standard location of "sshd_config" required by Delphix engine but I didn't find it neither in docs nor in community posts. What is the standard location for "sshd_config"?

    (2)
    Despite existing listener configuration in db host I get following error message.


    My environment

     
    You can see there properly discovered listener. This listener is working. I can connect to the database from outside without problems.

    How can I get rid of this error?

    Regards,
    Piotr

    Piotr,

    Oracle docs indicate a default file location of "/etc/ssh/sshd_config", but that if the SSHD daemon is started with the "-f" switch, another file location can be specified.  Running the UNIX/Linux command "ps -eaf | grep sshd" might reveal whether the daemon is reading from a non-standard location for the configuration file.

    As for the listener problem, I'm not quite sure what produces that fault, but looking at your screenshot and noticing that your listener is using non-standard port 1522, can you check that database instance to ensure that the Oracle initialization parameter LOCAL_LISTENER is set appropriately?

    Please let us know what you find?

    Thanks!

    Tim,

    I think I managed to get rid of both problems. It turned out that my target host had wrong format of /etc/hosts file. After changing to Oracle's recommended form error messages disappeared. Example of my current /etc/hosts on apps tier.

    127.0.0.1       localhost.localdomain   localhost
    ::1     localhost6.localdomain6 localhost6
    192.168.0.124   ebstarget20.kolibero.local ebstarget20
    192.168.0.123   ebstarget10.kolibero.local  ebstarget10

    So the problem was outside Delphix.
