Oracle VM Templates теперь доступны для платформы SPARC

Oracle VM Templates предоставляют возможность быстрого развертывания предварительно установленных и настроенных образов операционных систем. Используя Oracle VM Templates, вы избавляетесь от необходимости устанавливать и настраивать операционную систему и программное обеспечение. До недавнего времени такая возможность существовала только на платформе x86. С сегодняшнего для Oracle VM Templates доступны и для SPARC.

С выходом Oracle VM Manager 3.2 появилась возможность обнаруживать в сети сервера SPARC с технологией виртуализации Oracle VM Server for SPARC, и управлять виртуальными машинами точно так же как и Oracle VM Server for x86. Таким образом использовать все преимущества Oracle VM Templates.

Для получения большей информации рекомендую прочитать Oracle VM Templates now available on SPARC platform. Посетите Oracle Software Delivery Cloud чтобы загрузить доступные OVM Templates.

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.
