Oracle has NEW Virtual Machine Templates


The Simplicity of the Oracle Stack

Oracle beliefs in a total solution for your IT environment, they call it the Oracle Stack and you can explain it very difficult and stammering about or just introduce it with a small overview like the video below.


Oracle Real Application Clusters

Lower the Cost of Computing

Oracle Real Application Clusters (RAC) supports the transparent deployment of a single database across a cluster of servers, providing fault tolerance from hardware failures or planned outages. Available as an option with Oracle Database 11g, Oracle RAC is a key component of Oracle's private cloud architecture.

Oracle Real Application Clusters Overview

Oracle VM Templates

Oracle Real Application Clusters (RAC) 11g  Release 2 (x86 32-bit & 64-bit)


Oracle RAC is an option to the award-winning Oracle Database Enterprise Edition. Oracle RAC is a cluster database with a shared cache architecture that overcomes the limitations of traditional shared-nothing and shared-disk approaches to provide highly scalable and available database solutions for all your business applications. Oracle RAC is a key component of the Oracle Enterprise grid architecture.
The templates provide an easy and fast way of deploying an Oracle RAC cluster in Oracle VM for test as well as production environments. The templates are designed to build clusters of any number of nodes, while by default a 2-node cluster is created. The templates are available in the following versions (ordered by template release date):
  • Oracle RAC 11g Release 2, including Oracle Grid Infrastructure Patch Set two Update #2 (11.2.0.3.2) & Oracle Linux 6 Update 2, available from My Oracle Support under Patch number 13818831 for 32-Bit & 64-Bit Linux [Jun 2012]
  • Oracle RAC 11g Release 2, including Oracle Grid Infrastructure Patch Set one Update #6 (11.2.0.2.6) & Oracle Linux 5 Update 8, available from My Oracle Support under Patch number 14000016 for 32-Bit & 64-Bit Linux [May 2012]
  • Oracle RAC 11g Release 2, including Oracle Grid Infrastructure Patch Set two (11.2.0.3.0) & Oracle Linux 5 Update 7, available from My Oracle Support under Patch number 12694014 for 32-Bit & 64-Bit Linux [Sep 2011]
  • Oracle RAC 11g Release 2, including Oracle Grid Infrastructure Patch Set one Update #2 (11.2.0.2.2) & Oracle Linux 5 Update 6, available from My Oracle Support under Patch number 11836831 for 32-Bit & 64-Bit Linux [Jul 2011]
  • Oracle RAC 11g Release 2, including Oracle Grid Infrastructure Bundle Patch #2 and Oracle Database Patch Set Update #4 (11.2.0.1.4) & Oracle Linux 5 Update 5, available via Oracle Oracle Software Delivery Cloud [Apr 2011]
  • Oracle RAC 11g Release 2, including Oracle Grid Infrastructure Patch Set one (11.2.0.2.0) & Oracle Linux 5 Update 4, available from My Oracle Support under Patch number 10113572 for 32-Bit & 64-Bit Linux [Sep 2010]
  • Oracle RAC 11g Release 2, including Oracle Grid Infrastructure Bundle Patch #2 and Oracle Database Patch Set Update #2 (11.2.0.1.2) & Oracle Linux 5 Update 4, available via Oracle Oracle Software Delivery Cloud [Aug 2010]



Oracle Template Deployment


For more information about the latest Oracle Grid Infrastructure and Oracle RAC templates for Oracle VM refer to My Oracle Support note ID 1185244.1
The entire installation is automated, requesting minimal information (e.g. node names, IP addresses, etc.) from the user when guests are booted. Fully automated build of cluster (OVM2: directly from Dom0, OVM3: Using the Deploycluster tool) are also possible, including automated network setup for N-node clusters. The final cluster configuration adheres to the best practices for production systems (assuming the production implementation was chosen) as described in the "Oracle Real Application Clusters in Oracle VM environments" technical white paper.




Oracle VM HA and Oracle RAC

Template Highlights

  • NEW: Deploycluster tool provides fully automated end-to-end Oracle Real Application Clusters deployments on Oracle VM 3
  • All versions of the RAC Templates are fully supported on Oracle VM 2 and Oracle VM 3.
  • The Oracle VM templates use a minimal installation of Oracle Linux 5.4, 5.5, 5.6, 5.7, 5.8 or 6.2 system images for either 32-bit or 64-bit. Only basic RPM packages are installed.
  • Mixing and matching the OS and the Oracle disks is supported and easy to achieve.
  • The Oracle VM templates can be used to build clusters of any number of nodes using Oracle Database 11g Release 2, which includes Oracle 11g Rel. 2 Clusterware, Oracle 11g Rel. 2 Database, and Oracle Automatic Storage Management (ASM) 11g Rel. 2, patched to the latest, recommended patches.
  • The environment comes loaded with Swingbench, Oracle Cluster Health Monitor, OS Watcher, and more tools.
  • During the installation process an Oracle RAC database instance is created on all nodes by default.
  • Any number of nodes or instances can be added or removed from the cluster using a single command.

DeployCluster Tool

Oracle VM 3 users can benefit from the newly available DeployCluster tool to help further with cluster creation automation using the RAC Templates. The tool leverages the Oracle VM 3 API so that given a set of VMs it quickly boots them up sends them the needed configuration details, and an automated cluster build is initiated, without requiring the user to login to Dom0, any of the involved VMs or Oracle VM Manager.
