Comment on Oracle versus RedHat and VMware by Lenz Grimmer

Lenz Grimmer — Fri, 27 Apr 2012 15:33:18 +0000

Hi J, I just recently stumbled over this blog post and wanted to clarify two things, if you don’t mind.

You wrote: “Oracle’s Unbreakable Kernel is based off of RedHat’s Kernel.” – this is actually not the case. The Unbreakable Enterprise Kernel is derived from a recent version of mainline Linux, we try to minimize the number of patches we apply on top of it. The UEK will be updated to a new version from mainline every 12-18 months and is fully maintained and supported by Oracle.

With regards to the missing vmv_pvscsi driver – this was indeed a bug (as noted in the release notes) that was addressed in later errata releases of the Unbreakable Enterprise Kernel ( ELSA-2011-2010 for OL5/6: http://oss.oracle.com/pipermail/el-errata/2011-March/002008.html and http://oss.oracle.com/pipermail/el-errata/2011-March/002014.html)

Comment on Not all Oracle databases require a license by Leslie Agoras

I was curious if you ever considered changing the page layout of your website? Its very well written; I love what youve got to say. But maybe you could a little more in the way of content so people could connect with it better. Youve got an awful lot of text for only having 1 or 2 pictures. Maybe you could space it out better?

Comment on Oracle VM compared to VMware vSphere: Part 1 by J

Just as an aside to your comment, although I had concerns regarding the vSphere 5 licensing when it was first announced (and subsequently revised), I have yet to have any of the vRAM licensing restrictions actually effect my clients.

Hi
I’ve been using VMware products for a few years now, and the new Vsphere 5 licensing has made me look at alternatives like Oracle’s VM Server. I don’t have a dog in the race between Oracle and VMware, I’m not favoring either vendor.
But I will say that the OVM 3.0 is absolutely the worst piece of junk I’ve ever seen.it simply doesn’t work correctly.if you do manage to get things set up, you’ll still get
screen errors for various odd reasons ( Java?)..
the web interface OVM is garbage when compared to Vsphere..and for the $495 one-time licensing fee for Vsphere Essentials, it is WELL worth it..
with Oracle you get what you ( don’t ) pay for; it’s is free for a reason..because it is 100% pure junk…
download the 60-day trial version of Vsphere and compare it to the OVM and OVS..
there’s an old saying “if you can’t party with the Big Boys, don’t bother showing up”. Oracle needs to take that to heart..this OVS/OVM product is simply not ready for prime time..

Comment on Why Oracle VM isn’t enterprise ready by J

You can take snapshots of Oracle databases with both Oracle VM and VMware. It’s well tested and works fine as a crash-consistent machine image (if you’re not snapshoting the memory). I also believe Oracle on windows (and I know SQL server on windows) under VMware supports VSS.

Hello,
I;m new to vmware and oracle VM , up to now virtualization was solaris zones ( sparc / x64)
I have started with Vmware esx5 and ORACLE_VM 3.03
There is no doubt vmware beats oracle vm in the administration and management of the infrastrcture .
vmware vsphere management is logical and makes sense , it does a lot behind the scene for you and it WORKS !!
oracle_vm management is all but logical , documentation is incomplete and done for experts !! after more then a week of work , I installed my first Virtual machine. Now I’m trying to start the console of that machine for 2 days .
Tried using I.E on windows / Firefox on Windows , never got it working.
I eventually had it running using firefox on solaris !!
but it is not consistemt , sometimes it works sometime it just do no start !! no message no nothing.
I really wonder if companies are using oracle vm in a production environment ..
I have seen a lot of doc on oracle VM 2.2 but 3.xxx seems to be new and full of bugs …
Really disapointing ..

Comment on On Oracles commitment to Linux by Charlie Johnson

Has there been any news from Oracle on RH6? It’s now 2012 and rh6 is at 6.2. From the conversations I have had with Oracle, they are still making no comment or commitment to RH6. Has anyone heard anything one way or another?

I’ve had that experience once. I got the SR duty managed immediately and the issue was then taken care of satisfactorily. Analysts (and even occasionally DBAs) get things wrong once in a while.
