This is just a note to myself. The command adds user oracle to the vboxsf group. Don’t even try chmod or chown on the mount point, it won’t help. Replace oracle with your own uid.
sudo usermod -a -G vboxsf oracle
Make VirtualBox Shared Folder Mount read / write for a non-root User

Oracle announcing Oracle Public Cloud – First comments.
October 6, 2011 by Leave a Comment
I am at S.F. at the Oracle Open World conference right now where Larry Ellison announced the Oracle Public Cloud in an entertaining and rather fun presentation just an hour ago. To see some more photos of the event and my paparazzi shot of Sting who already showed up for some 30 seconds: check out the Facebook site of my Oracle Cloud Computing book.
Larry picked up many ideas that I published earlier this year in my cloud computing book:
He was talking a lot about migrating from one cloud to another (mostly using AWS as an example, so they seem to be on the friend list). Also he emphasized that simple multi-tenant SaaS offers such as Salesforce.com with a shared DB are not real clouds and risky (because of the shared DB 🙂 ).
When Oracle’s position about clouds was rather fluffy (should I say cloudy?) even one year ago, I now hear them talking more about elasticity, self-service, chargeback etc.
What I didn’t like: So far this does not include pay-per use yet (one of my 4 criteria of cloud computing). Larry mentioned a monthly subscription during his keynote which was confirmed in the Thu morning keynote. Yet Oracle Enterprise Manger 12c is announced to provide metering at various levels.
I will post an update here as soon as there will be more details out tomorrow.
Apart from announcing the Oracle Public Cloud also Oracle Social Media (a part of Fusion Applications) was announced. See fotos on Facebook.
AWS outage destroys EBS-based AMIs in Europe region
August 14, 2011 by Leave a Comment
I always recommend to create your own EBS-based AMIs (e.g. for running complex software such as Oracle Fusion Middleware). This hold true for the classic AMIs as well as for the converted Oracle VM templates. Never rely on the existence of AMIs provided by Oracle because:
– Oracle can change or update (or remove) them any time.
– They often don’t exist for certain AWS regions, they are S3-based or only exist based on 32-bit OEL instead of 64-bit.
– Also, the AMIs provided often don’t exist for a specific version of Oracle products.
So always create your own copy! Yet here is something to consider:
AWS broke an EBS-based AMI of mine by deleting arbitrary block in the image. This is particularly annoying since there is no easy way to create an offline copy an EBS-based AMI. You could rsync the running image to local computer but there is absolutely no support to get this done in a user-friendly way from the AWS console.
The good: They informed me in time (being in Sydney if something happens in the EU regions gives you an advantage) and sent an apology. They also replaced the deleted blocks with empty blocks.
The bad: It cost me several days to create this AMI which was an OEL EBS-based, full-blown installation of Oracle SOA Suite 11.1.1.5 (I still have to check if it will be usable after a file system check).
For a more detailed explanation of what happened take a look at Amazon’s summary of the events. It summarizes to an error in the EBS software that was overlayed with a power outage in Dublin.
Hello Amazon: Why don’t you provide an easy way to have an offline backup of EBS-based AMIs for disaster recovery?
