Oracle Database 10g and Real Application Cluster certified on Sun Logical Domains (LDoms)

Oracle Database 10g and Real Application Cluster (RAC) now officially certified and supported on Sun's Logical Domains (LDoms). For details also check technology support matrix. With LDoms virtualization technology administrators can achieve great level of resource management and security level at the same time having higher utilization of servers.

Among several types of deployment I would like to mention one specifically for developers. By using LDoms now you can have single box with a number of guest domains configured as a cluster nodes. Start with making cluster on a chip.

Stay tuned for real world configuration example.

Hi Seenivasan,

By "exporting virtual disk" do you mean exporting physical LUN?

You may check BluePrint we wrote http://blogs.sun.com/pomah/entry/running_oracle_real_application_clusters . The same applies to 11g, except patches.

Hey Roman.

Trying to assist a client in consolidating from Sun USIV+ V490 servers to the T5x40 servers. 2-node Oracle 10g RAC nodes are being deployed across three different projects. So, instead of deploying 6 V490 servers (3 x 2-node RAC), we want to move them to 2 x T5x40 servers configured with 3 LDoms each, to host the three projects. IBM snuck in and presented our clients with 2 x 8-way p770 servers with 3 x LPARs each, at half the total core count as a solution. We're ready to position the Oracle/Sun and Solaris binary compatibility story. But is there something to be leery of, when positioning something like two T5240 Servers in the RAC configuration I mentioned earlier?

Thanks for any input you could provide

Hi Dante,

Thanks for the interest.
You may check the folowing document if you didn't already

We put a lot of efforts and our time to make this certification done and hopefully we were able to resolve all gotchas.

I'd like to repeat one recommendation here - is not to share one core between two domains.
