An advantage the Oracle cloud provides over other clouds when using Oracle databases is that they include transparent data encryption free by default for all versions of the database and you do not need to license it separately. By default a cloud database uses encryption…

KVm is a type 2 Hypervisor. It runs as an application inside a full fledged operating system. Thus the hypervisor layer is not as thin as in a dedicated type 1 hypervisor like Vsphere ESXi. Given that it does seem to be comparatively lightweight comapred to other such…

Hi Jaari, it seems itcentralstation is the one who has lumped both solutions under the same category sine they come from the same vendor. ideally there should have been two separate categories Oops actually Oracel VM virtualbox is what Oracel calls virtualbox now :)…

Basically if you want to run any oracle database or packaged product OVM is compatible. If its windows OVM runs in HVM ( hardware emulated mode) which is not as good as PVM in some respects .

I would like to see improved I/O and latency , hvmlite support. I love the fact that now we can go with hugepages even with the limitations we have because if yiou want to run a database then hugepages is the way to go. Of course now with Exalogic and PCA using OVM oracle…

Hi, It does seem to me that a few of your points are overly harsh, for example you say that Oracle database is a single point of failure. It was possible to migrate the database to a RAC instance if you needed that sort of high availability however it is also important to…

P>S I assume you are referring to instance caging when talking about every database not being able to see every cpu. that is not entirely accurate since instance caging does not pin processes to cpus but instead keeps a tab on the total used cpu by a processs and prevents it…

What is the use case of Vblock over Exadata ? Given that vblock uses vmware which means you need to devote the whole vblock to oracle db from a licensing perspective is this really a good choice for a database ?

So as is clear the integrated support is definitely a plus point. Also if you are an all oracel shop you get the Oracel vm support free with the support of your Oracle hardware server like a conventional sunfire x6-2 .

There is a great comparison of Vmware vs physical vs OVM by flashdba. Remember that he used all flash storage hence real world values will have smaller variance as disk itself will introduce latencies that are similar for all.. having said that the difference between OVM and…

Yes use of Oracle VM is certified. In fact you can get both standard images a well as exalogic specific images for EBS in case you are using the special Exalogic versionof OVM that connects via infiniband.

Definitely the fact that oracle recognizes OVM as a trusted partition that can be used to reduce overall licensing is a major advantage compared to other x86 virtualization techniques.Since today's chips have insane numbers of cores sometimes this is the only way to keep…

I think hands down it's Exadata since for the front end apps it's just another Oracle database which means everything under the sun is compatible with it.
