White paper updated: Running Oracle Real Application Clusters on Oracle VM Server for SPARC 2.0

"Running Oracle Real Application Clusters on Oracle VM Server for SPARC 2.0" white paper was updated to reflect all the Changes and Improvements of Oracle VM Server for SPARC 2.0.

Some key points from white paper:

  • UltraSPARC T2, T2Plus and SPARC T3 processors only supported. T1 is not.
  • Oracle Solaris 10 09/10 (Update 9) or later is required.
  • Running Oracle RAC on Oracle VM Server for SPARC requires the use of Oracle 10g R2 (Oracle 10.2.0.4) or later with the same patch set on all nodes.
  • Link-based IPMP enables you to build IPMP group of private (and/or public) network interfaces within guest domains. No need to have host based routing anymore!
  • With Memory Dynamic Reconfiguration you may add more memory to guest domain while database instances are running. When going down, don't go below SGA+PGA or you may end up with swapping.
  • How to setup Jumbo Frames example given.
  • Pay attention to Availability white papers mentioned in the Reference section.

The authors would like to thank Daniel Dibbets, Sridhar Kn, Rahim Mau, Wataru Miyoshi, Khader Mohiuddin, Ezhilan Narasimhan, Gia-Khanh Nguyen and Uday Shetty.

Script to check CPU cores ownership on Oracle's Sun SPARC Enterprise T-Series systems

There are few scripts in my test lab which I am using while running tests. While most of them are very specific, there is one which may be of interest for you. This script allows you to verify if any CPU core is shared between two or more logical domains. читать дальше...

Running Oracle Real Application Clusters (RAC) on Sun Logical Domains (LDoms)

BluePrint of Running Oracle Real Application Clusters (RAC) on Sun Logical Domains is available now. In this blueprint you will find step-by-step configuration example of two nodes in two guest domains located on two separate boxes. Use it as starting point to build your own cluster.

This article discusses running Oracle Real Application Clusters (RAC) on servers configured with Sun™ Logical Domains (LDoms). Sun LDoms virtualization technology allows the creation of multiple virtual systems on a single physical system, and enables fine-grained assignment of CPU and memory resources to an Oracle RAC workload. When deployed on Sun's CoolThreads™ technology-based servers, with up to 256 threads per system, this solution provides a powerful platform for both development and production environments. In development environments, multiple Oracle RAC nodes can be deployed on the same physical server to reduce hardware costs, while a production environment can place each Oracle node on a separate physical server for increased availability.

The authors would like to thank Sridhar Kn, Ezhilan Narasimhan, Gia-Khanh Nguyen, Uday Shetty from Sun Microsystems, as well as Rahim Mau, Khader Mohiuddin from Oracle Corporation for their contributions during the certification of Oracle on Sun Logical Domains.

Configuring Oracle ASM in Solaris Container with Solaris Volume Manager.

We have learned how to configure Oracle in ASM in Solaris Container. For this we setup our container with raw device access. While this works good it is not good idea to expose device names into container. Virtualized OS administrator should not know about devices in global container. And being attached to special device is not giving flexibility. In this exercise we will migrate from raw device onto SMV metadevice. читать дальше...
