Oracle 11g in Virtual Machine

Hi Gurus,
I would like to gather input from you, what is the pro and con, advantages and disadvantages for putting Oracle 11g in Virtual Machine (VMWare, Oracle VM, Virtual Box, etc.)
and will there be any licensing issue with this.
Currently we have CPU Based license for our Production and Named User license for the Dev.
thanks in advance for your time.
Lie

If you put Oracle db in VMWare then you have a non-certified configuration, and you could be alone (I mean without Oracle support) if you have a problem than Oracle support cannot reproduce in a certified configuration. I would avoid a non-certified configuration for a production environment.
So, two choices :
* go for Oracle VM
* go without VM at all

  • Oracle r12 on virtual machine

    Hi,
    I have installed Oracle r12 on virtual machine (linux) on my laptop.
    I have noticed that virtual machine loses date/time.
    How can I keep the date/time on my virtual machine in sync with my laptop date/time so that date and time in Oracle R12 is current?

  • Oracle database on virtual machine without a license

    Hi,
    Someone told me earlier that you can install Oracle on a virtual machine without buying a license. Do you know an internet link that could confirm this.
    Thanks.

    What about preconfigured virtual machines Oracle distributes? Do you have to have a license for them as well? I'm pretty sure you do, it would say in big letters if you didn't need a license...
    I not can you alter the installations by building additional instances?Yes, you can add instances (except to an XE database) for testing but you asked about licensing a server...

  • Oracle VM as virtual machine - Networking

    hi
    I have seen some docs about networking, and thus how to install oracle vm 3.2.x as virtual guest on top of the cloud stack (HA enabled).
    Is there any best practices document for networking in this fashion?
    We like to have 3 networks.
    Network management VLAN1 (local IP adresses)
    Storage Network VLAN2 (local IP adresses)
    VM Network VLAN3 (public IP's)
    While the oracle vm runs as a guest, there is only the public network wehere we can select for nic's.
    It's possible to run OVM as guest with diffrent network segment? Should we use this configuration in a production ervironment
    Thanks for your support

    I was making this too complicated... I set up a squid proxy on a different machine and it all works well.

  • Oracle tuxedo and Oracle tuxedo message queue on top of a virtual machine.

    Hi buddies.
    how is it going?
    A quick question.
    So we are going to go live  using Oracle Tuxedo 12.1.1.0 with Distinguished Bulletin Board Liaison and Oracle Tuxedo Message Queue 12.1.1.0  on top of a Virtual Machine (VMWARE) running Oracle Linux 6.2. However we want to know if there are any recommendations or mishaps in which we may face ahead by running Oracle Tuxedo on a virtual machine?
    I mean, I am wondering if I have to worry about kernel parameters, virtual machine parameters or any other thing from which could mess up everything.
    Another question.
    Does oracle also provide virtual machines certification where Oracle tuxedo would run on top of ?
    Todd Little-Oracle
    Maurice G

    Hi Bruno,
    I'm not sure what you mean with Distinguished Bulletin Board Liaison.  I'm guessing you mean a clustered or MP configuration?  And is it truly a clustered configuration or just a single machine MP configuration?
    Regarding configuration, are you using Tuxedo services as well or just Tuxedo Message Queue?  The biggest issue related to OS configuration is around IPC resources.  If you do a tmloadcf -c on your UBBCONFIG file, it will help you determine the minimum IPC resources required.  In general I suggest configuring significantly more resources than the minimum to allow for future changes and for some of the parameters for heavier loads.  In particular IPC message queue parameters are heavily dependent upon load.  So make sure the maximum message size and queue size are large enough for your anticipated workload.  You can monitor them under load using the ipcs command.
    We don't certify virtual machine environment but support them as long as the VM vendor assures compatibility, which obviously VMware and Oracle VM both do.

    this?... as in im strugeling to find any guides for running oracle on a virtual machine with windows hostThe reason you are struggling to find any such guides is because there is no reason for them to exist. Oracle only cares about what OS it is running on. If you have a windows host with a virtual Linux, and Oracle is installed on that virtual linux, then Oracle only cares about the linux. It doesn't even know about the Windows, so why should there be any guides dealing with that? Running oracle on a virtual machine is just like running it on a physical machine. That's the whole idea of virtualization.

  • Connecting one database to many virtual machines

    Hi Experts,
    We have set many Virtual Machines (VM) in Windows Server already. Each Virtual Machine will be used to install SAP module for instance VM-1 for BI, VM-2 for Solution Manager, VM-3 for IDES, VM-4 for EP, etc.
    The questions is:
    Is it possible to integrate one Data Base (Oracle) to all virtual machine? and how to do it ?
    Thank you for the respond.
    Gruesse,

    It is called "MCOD" - http://service.sap.com/mcod
    Personally I wouldn´t use such a scenario. In case you want to upgrade/patch the database all instances will be down.

  • Where can i find oracle 11g csi number

    Hi oracle Lord’s
    This is Arun, I’m facing some problem while I installing oracle 11g on my machine. I downloaded oracle 11g from the below link
    http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html.
    While I installing oracle 11g it will ask CSI Number, from where can I get the CSI number.
    Thanks in advance.
    Regards
    Arun M M

    You need to buy from your local oracle partner. This is the customer service identification number which need to log in to metalink support. But you don't need CSI to install oracle database. Avoid to check the latest patch version which need the CSI for connecting metalink.
    In this paper we will install the 11.2.0.1 release of Oracle Database 11g. This is the base distribution of Oracle Database 11g release 2. Be sure to check Oracle Support’s Metalink at http://metalink.oracle.com to see if a newer patch set has been released since this paper was published. You will need a valid Customer Service Identifier (CSI) number in order to access the Metalink website.
    Source : http://www.dbspecialists.com/oracle11glinux.html
    Also,
    2.4 Preinstallation Requirements for Oracle Configuration Manager
    During installation, you are prompted to provide information required to enable Oracle Configuration Manager. In the event that you need to place a service request with Oracle Support, the configuration information can help to provide a more rapid resolution to the service issue.
    You can enable Oracle Configuration Manager during or after installation, or choose not to enable it. To enable it during installation, you must have the following information available:
    Customer Support Identification Number (CSI) that identifies your organization
    OracleMetalink user account name
    Country code associated with your service agreement
    So, don't install OCM during the installation.

  • How to deploy oracle 11g under cold failover cluster

    Hi,
    I am trying to install oracle 11g under failover cluster environments. I am trying to find some oracle documentation about it. But not able to find one. Can anyone help me. Please i need it badly.
    we have two servers sun solaris 10. on which we have failover cluster being installed. one is active while one is passive. How can i install oracle 11g on this failover clusters. did i have to install oracle of shared SAN. what are the extra configuration i have to do please help
    Also is it wise to install 11g warehouse with fail safe or use RAC.
    regards
    Nick
    Edited by: Nick Naughty on Feb 1, 2009 4:02 AM

    thanks alot for reply.
    I am of the same point of view. but the machine i am working on is sun solaris 10 with two partitions finance and accounts which have been protected by a failed over machine having two partitions finance and accounts and i think you are right these are the same shared storage folder which are mounted on active machine as well as on passive machine.
    Now my question is if i install oracle 11g on one machine without oracle cluster then sun cluster should be able to mount the database in case the primary machine fails.
    I have tried hard to get some documentation on this top but nothing so far. please help

    Thanks :)As far as I understand it this is not really VM related.
    You have an existing linux machine .... uname -a ... with a partiocular OS and kernel and set of packages installed ....
    And a guest VM running linux ... uname -a .... with hopefully the same/similar OS and set of packages installed, similar users, directory layout etc.
    And you wish to get the Oracle (Classic RDBMS) home software cloned/migrated and an oracle database cloned/migrated.
    There's a number of different senarios here ... can i help you out .... (the answer is I could but i dont have time).
    The start point is good planning and careful notes if you are attempting to change any versions / layours etc.
    You might have stages like (this is a top of head fagpacket and perhaps not best terminology):
    - Install basic Linux software on VM guest.
    - Install additional linux packages
    - create groups, users, directories, system parameters etc.
    - Create or clone oracle home.
    - clone oracle database by eg RMAN or otherwise.
    Different forums may help different stages if necessary.

  • A few question regarding oracle Vm (and virtualizing Db 11g)

    Hi,
    I've just started evaluating Oracle vm for our next deployment.
    One of the systems I'll need to virtualize is Oracle db 11g. As far as I understand the oracle DB template only comes with ASM? I would prefer to use LVM. What is the best way to install db into virtual machine without asm? Should I start with EL 5.2 and configure it, or could I somehow use the EL that comes with the template?
    Regarding LVM: I'm planning to create different volume groups, each with just one logical volume. These volumes would be mounted to guest as /u01, /u02 ... and so on. All volumes will be created on mirrored disks/partitions. Later, I could just move, expand, strip volumes as db usage will require. Does that sound ok?
    And another question regardin oracle vm: in the manual, chapter 4.6.2 says: "Install an operating system. This may be done a number of ways.
    ■ Install an Oracle VM Server-enabled operating system from CD-ROMs...."
    Is there a list of server-enabled operating systems anywhere? And maybe more detailed explanation of this step?
    Thanks

The Database template is designed to automatically configure and provision the database with ASM and would probably take longer to dismantle.

All volumes will be created on mirrored disks/partitions. Later, I could just move, expand, strip volumes as db usage will require. Does that sound ok?It sounds OK, but ASM does all of that and more. It is also faster (particularly on Oracle VM, as it uses direct access to the disks). ASM also does automatic data levelling and striping. With 11g, I would strongly recommand ASM over LVM for your storage.
    Is there a list of server-enabled operating systems anywhere? And maybe more detailed explanation of this step?There isn't a list -- that's possibly badly worded as well. If you don't want to use one of the paravirtualized Oracle Enterprise Linux templates available on eDelivery, you can use any operating system installation CD in ISO format. Note that installations from an ISO are done as fully virtualized guests (i.e. hardware virtualized) and require Intel VT-x or AMD-s extensions to be present and enabled. Hardware virtualized guests are also not as fast as paravirtualized Linux guests.
    Oracle only certifies Database 11g running on Enterprise Linux in paravirtualized mode. The simplest way to deploy this is to use the provided templates.
