VirtualBox 4.1.18 Released…

VirtualBox 4.1.18 has been released. It’s a maintenance release and the downloads and changelogs are in the normal places.

It’s been about 2 years since I switched across to VirtualBox (when the shared virtual disks feature was introduced). In that time there have been loads of updates to the product. In the same time frame, VMware Server has had zero releases. I still get a lot of people writing to me about issues with VMware Server installations. I immediately tell them to ditch it. :)

PS. I’ve got nothing against VMware’s paid-for offerings, which do get updates. I just don’t see the point in using them when VirtualBox is free and works great for me.

VirtualBox 4.1.16 Released…

VirtualBox 4.1.12 Released…

Just a couple of weeks after the last release, to make sure we didn’t think it was an April fools joke, Oracle waited until April 2nd to release VirtualBox 4.1.12 into the wild. :)

You can see the changelog here.

Happy upgrading.

OUGN Spring meeting 2012

I had the great pleasure to spend the better part of last week at the Norwegian Oracle User Group’s spring conference. Martin Nash and I helped promote the Real Application Cluster platform on the attendees’ laptop in a program called RAC Attack.  RAC Attack has its home on the wikibooks website http://racattack.org where the whole program is documented and available for self-study. The purpose of the hands-on labs which Jeremy Schneider started a few years ago is to allow users to get practical experience installing Oracle Linux, Grid Infrastructure and the RDBMS binaries before creating a two node database. Following the database creation a practical session ensues which explains certain HA concepts with RAC such as session failover. We are planning on greatly enhancing the lab session as we go along. If you have any suggestions about what you would like to see covered by us then please let us know!

Oracle 11gR2 RAC on Oracle Linux 6.1 using VirtualBox…

It’s all a bit last minute, but today I decided to do an Oracle 11gR2 (11.2.0.3) RAC installation on Oracle Linux 6.1 using VirtualBox. The 11.2.0.3 patch has fixed all of the installation issues related to RAC on OL6.1, so it was pretty smooth. The procedure can be seen here.

As noted in the article, the screen shots of the GI and DB installers are from an 11.2.0.1 article. I’ll update these screen shots when I get back from OpenWorld. Like I said, it was all a bit last minute. :) Normally I wouldn’t put an article like this live (and you can see it’s not on the homepage yet), but I get lots of questions about this subject, so I thought I would make it available to make my life easier.

Cheers

PS. There is no suitable oracle-validated package available for this at the moment, so the prerequisites have to be done manually.




VirtualBox Cloning: A minor warning…

The cloning feature in VirtualBox was a welcome addition, but there are a couple of fringe issues to be aware of:

  • If you use the cloning feature to clone a VM that has shared disks (like in a VM RAC setup), the shared disks are also cloned, so you end up with a new VM that is not accessing the original shared disks, but has a new set. I’ve put a note about this in my VirtualBox RAC articles and suggested you still use the old method of cloning the virtual hard disk manually. I guess for most people this is not a big deal.
  • The virtual disks of a clone get placed in the default location. Once again, not a big deal unless you try to spread your virtual disks onto different spindles to get better performance.

Like I said, these are very edge-case issues and not a reason for most people to avoid the cloning feature.

11gR2 RAC on Windows 2008 using VirtualBox…

As I’ve mentioned before, I’ve kinda ignored the fact that any operating system other than Linux (specifically Oracle Linux) exists. It’s quite easy to do when you are working with Oracle products and you get to choose your own environment. :)

As a vague nod to the fact that Windows does actually exist, I’ve finally got round to updating my Windows virtual RAC article.

Windows 2008 is an unusual operating system in some respects. The RAC installation is pretty simple really, but finding some of the config dialogs is a complete nightmare. Chains of menus, dialogs, buttons and hyperlinks to get you to the dialog you need. What’s worse, some of the menus are hidden unless you remember to “Alt” or “Alt+N”. Crazy! If I was using Windows on a regular basis I think I would just memorize all the dialog program names and start them directly from the Run menu. It’s got to be easier than traversing that nightmare. I remember when Windows was considered the easy option. It doesn’t feel like the case anymore. :)

In related news, yesterday I got an invite from Jeremy Schneider to help out at RAC Attack at OOW 2011. That should be fun. See you there! :)
