Virtualizing whole infrastructure - vmware, virtualbox, oracle vm ?

Hello All,
We have the project of virtualizing the infrastructure (consisting of DBs and iASs on Red hat 4.6 (no RAC or ASM)).
I have used vmware and know the procedure: you install vmware server, you create VMs, install an OS, access the VM, and then install what is required. Similar on virtualbox.
1 - Is VMware or virtualbox certified for oracle? or only Oracle VM?
2 - The procedure on Oracle VM is the same? After installing the VM Server, can we create VMs on any OS? Or are we limited to templates?
I visiited

and
note Certified Software on Oracle VM [ID 464754.1]
but didn't come up with any clarifications.
Any help is much apprecciated.
Thank you.

UPDATE well , I suppose that the note
Oracle Linux Support Policies for Virtualization and Emulation [ID 417770.1]
answers my questions #1. "no for vmware/virtualbox. yes for oraclevm".

There are two important points that you should understand:
1. Oracle tries to spread FUD (fear, uncertainty, and doubt) and running Oracle database on VMWare. They suggest that they don't support it, but they DO support it, when they're pinned down. We've been all through this at my workplace. The situation is: If you run Oracle on VMWare, and have a problem, and open a service request with Oracle, IF (and this is a big IF) Oracle thinks the problem you're having may be caused by running on VMWare, they MAY require you to show that the problem exists on a non-VMWare platform. But almost ALL problems you'll have with the database will not fall under that "IF".
2. But here is the killer reason why you might not want to used VMWare: If you run Oracle DB on VMWare, you must license EVERY core in that box. If you think about how many cores are in a small 2-socket server (the ones we just bought have TWELVE), the cost to license Oracle on a $10,000 server may be far more than you can afford. And if you can't fully load up all those cores, or if you are running things besides Oracle on those cores, you're paying for cores you can't use. HOWEVER, on Oracle VM, you pay ONLY for the cores that you allocate to the virtual machine(s) that are running Oracle DB.

Migrate from vmware to oracle virtual machine having some error

Hi
I am migrating the vmware with oracle virtula machine for that I have downloaded the OVFTool and run the following command
ovftool.exe c:/../vmware.vmx d:/../vmware.ovf
successfully I am able to migrate .vmx to .ovf file.
then when I opened the same .ovf file with OVM and its creates the anithere .vmdk files.
but then after when I try to reboot the same its gives the following error
Error Loading operationg system
Please guide am I missing anything in migration ????

Thank you for the information. The link you have mentioned is about migration the environment of a machine to a VM. But i'm looking for migrating an Oracle Database 11g from a Physical Machine (Linux x86) to a Virtual Machine( Linux x86) created using Oracle VM. Can you help me out in this.
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.

VMWare: 1 Oracle installation per virtual server, or 1 separate install

The scenario is that we are going to put our support benches on VMware.
The question is: should we have 1 oracle installation per virtual server or a separate virtual server for oracle.
If we go for the 1 oracle installation per virtual server, this mimics our customer environment.
If we install oracle separately, then we have to run two virtual machines. One for Oracle(with one instance per customer) and one for the Product which connects to the appropriate instance.
Looking at it I'm inclined to go for the 1 orcale installation per virtual server, as this will allow for easier maintenance and upgrade paths.
Apart form disk space , are there any other drawbacks?
Are there any advantages to having oracle on a separate virtual machine?

VMWare is not supported for Oracle, so if this is to mimic a customer environment, then you should be aware of this. In my personal experience I have not seen any noticeable difference from the testing and learning point of view.
Installing Oracle on VMWare at the end of the day will consume the resources of the server where the VM is hosted, so it is all up to the CPU and memory resources you have in your host server. A drawback is the hard disk speed, the lower the more noticeable performance reduction, so be aware of this. It is advisable, you should make sure you have installed the VMWare tools.

Manual conversion from VMware to Oracle VM

Hi,
Could anyone please give me a detailed procedure about converting a machine from VMware to Oracle VM format?
Our VMware machine have the "-flat.vmdk" format and OVM manager is not converting them. I was advised that I need to do the whole procedure manually.
Thanks in advance for your help,
Sam.

Guys, I am happy to advise that we got a solution for this problem.
For all those who are unable to convert from WMare to OVM because of the extension *-flat.vmdk just contact Oracle support and ask for a patch for BUG 9569399.
Regards.

Solaris 10 virtual machine for VMware

I've tried the "Solaris 10 OS, AMD x64 Platform - Solaris Enterprise System Virtual Machine for VMware (Solaris 10 11/06) 3.0". I've d/l the virtual appliance for vmware one can find from there : http://developers.sun.com/solaris/downloads/solaris_apps/index.jsp#vmware
I encountered 2 problems :
The first was the network (netcard) wasn't recognised at all. It's strange because the settings should be the same for every vmware virtual machines. It may be because I'm running the latest version from vmware (10.0.2). The default option was NAT, and I tried the others as well. All other systems I'm using with vmware are working correctly, including the opensolaris "Nexenta".
The second one was with the screen resolution, it was excessively huge, around 2800 x 2000. I couldn't change it in the gnome desktop (the option had no effect). I managed to change it by altering the /etc/X11/xorg.conf file. The same was for the keyboard settings, I couldn't switch to azerty (french) keyboard. I had to change it in xorg.conf file.

im new to vmware too, but just wan to share my experience with you.

Need to know if Firefox 6 is compatible with Citrix XenApp Server 6 running on Windows Serve r2008 R2 virtualized on a VMWare environment. Thanks in advance!

We are setting up a new environment for a client based on Citrix XenApp Server 6 running on Windows Server 2008 R2 which is virtualized on a VMWare hypervisor. Client uses Firefox and we need to know if it is going to work or not. If not, what is the root cause (i.e. XenApp, Windows Server 2008 R2, virtualization).
Thanks again! :)

I only ask because, in the past we were able to install a related product, InDesign CS5 in Citrix. In fact, Adobe had published documentation for doing exactly that: here. I just haven't seen anything similar for Illustrator CS6 and wanted to check.

Virtual Box or VMWare?

I have a MacBook Pro 15" and I need either Virtual Box or VMWare for college to be able to complete one of my computer science classes.
Which one would you guys recommend? I'm getting a lot of mixed results whenever I read reviews.
Thanks!

For me, I found Parallels to be a better fit than VMWare Fusion. Since Virtual Box is free, and VMWare & Parallels both offer free trials, why not just try them all out and see which one works better for you?

Mountain Lion procedure to clean up (shrink) a Snow Leopard virtual machine under VMware Fusion 5.0.3

Procedure to clean up (shrink) a Snow Leopard virtual machine under VMware Fusion 5.0.3
1.     Backup your existing Mac OS X Snow Leopard virtual machine
2.     Right click the Mac OS X Snow Leopard virtual machine
                    Click Show Package Contents
                    If there are a number of Virtual Disk files then Fusion is allocating space for the virtual machine in 2 GB segments
                    Close the Package Contents folder
3.     If the Snow Leopard virtual machine is segmented then convert it to a single Virtual Disk.vmdk as follows:

So if the vendor doesn't provide an uninstall program or instructions, we're just stuck with stuff we may no longer need?
Pretty much. You can always erase your hard drive and reinstall the OS. Some people may attempt to talk you through manually deleting files. I try very hard to avoid doing that because 100% of the time, the person I'm trying to help can't find the files and, instead, starts randomly deleting required system files. Then you have no choice but to reinstall the OS.

Infrastructure suggestion for Oracle RAC and Dataguard

Hello,
We are working on migration business proposal and need to suggest HA and DR infrastructure solution with Oracle 11G databases. I am thinking to suggest Oracle 11g RAC and Dataguard to meet this requirement. We also wanted to cover Dev, Test and Pre Prod along with Prod in new environment. Can someone suggest cost effective, stable and scalable infrastructure for this requirement
Best regards,
Venkat

In terms of cost ? Perhaps.
In terms of performance? NO.
Bear in mind I'm not trying to sell anything here, but in my experience hardly anything matches the performance of Exadata. It has specific features for the DB such as de iDB protocol which enables the offloading of queries to the exadata storage servers. More unique features include: storage indexes, HCC compression, smart flash cache... It's all a matter of how much you want to spend.
Yes, you can have all your servers on the same box if you want, just make sure it is not a single point of failure. (Have appropriate safeguards in place in case of power failure, Data center catastrophes, etc). In case of LPARs on the same box, be aware of one server over-utilizing resources which would affect the other LPARs (configurable).
More info on Exadata: http://www.oracle.com/technetwork/server-storage/engineered-systems/exadata/dbmachine-x3-twp-1867467.pdf
If your company has a tight budget you might also look at your options with Database appliance: http://www.oracle.com/technetwork/server-storage/engineered-systems/database-appliance/documentation/oracle-db-appliance…
Database appliance has more flexibility in terms of licensing and it's also a complete hardware solution from oracle for Databases.

How can OSX 10.7 be virtualized in a VMware Hypervisor 5 envrionment?

I'm trying to virtualize an OSX 10.7 instance in my VMWare Hypervisor 5.0 cluster. I'm having issues getting the install to run (it just hangs when the virtual machine trys to boot the image). Is this something that's supposed to be supported?
My grounds for this installation are to help create a more robust Lion Server infrastructure to support numerous mobile devices.

I do not have a MAC. I'm running an Intel based server using Xeon CPUs.
Just an FYI: VMware added support for installing ESX5 to Macs so that you could legally run OSX VMs with the ESX hypervisor. The catch is that for the moment only the Apple Xserve 3,1 is on the compatibility list. I'm assuming that VMware is testing Mac Pros to add to the compatibility list and many are hoping that Minis will get added also. But since Apple stopped selling Xserves and with the uncertainty regarding the Mac Pro's future, and both Apple and VMware's policy of not discussing future plans, anyone interested in OSX vms on ESX is kinda in a bind.
Going outside of a type 1 hypervisor, you can get a Mac, install a type 2 hypervisor like Parallels or VMware Fusion, then you can still legally have OSX VMs. If you're already running ESX, then you are arguably better off getting Fusion since the virtual machines are compatible between Fusion and ESX. (Mostly anyway, or at least easier to convert between Fusion and ESX.)

VMWARE vs ORACLE VM -- an important question

The xen hypervisor does not present the same driver for hardware devices such as nic, scsi controller which means that we would have to manage device drivers like we do with the different operating systems (win and lin/unix) whereas, VMWARE presents a virtual driver to all the operating systems and it appears as the same driver. Basically, vmware virtualizes the hardware presented to virtual machines where virtual machines running on oracle vm will need native drivers.
Is the above statement correct.....Do we need separate drivers for guest OS in oracle VM ??

user13673517 wrote:

In the case of emulated devices, they are generic IDE/SCSI controllers and the a Realtek NIC. All certified guest OSs for Oracle VM have these drivers built-into the base OS installation. For paravirtualized devices, Linux and Solaris already contain the device drivers for these devices and we provide the PV Drivers for Windows software for Windows.
This is similar to VMware Tools, to provide optimized device drivers for the devices on the system.
