Oracle VM Templates Best Practices for Rapid Oracle Database Deployment

Oracle VM application driven architecture is designed to enable rapid application deployment. With the use of Oracle VM Templates, sophisticated applications such as Oracle Database or Oracle Real Application Clusters (Oracle RAC) can be deployed in minutes—10x faster than with other solutions.


The Oracle VM Templates for Oracle Database provides a framework that fully automates the creation of a Single Instance, Oracle Restart (Single Instance/HA) or Oracle Real Application Clusters (RAC) configurations in an Oracle VM environment. In a matter of minutes the versatile and powerful Oracle VM Templates for Oracle Database can be cloned into any number of VMs which could be deployed as a Single Instance, Oracle Restart (Single Instance/HA) or Oracle RAC of any number of nodes.

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 are designed to provide a fast and easy way of deploying Single Instance or Oracle RAC cluster in Oracle VM for test as well as production environments. The templates are available in the following versions (ordered by template release date):

NOTE: It is supported to mix Oracle & OS disks to obtain desired combination.

For more information about the Oracle VM Templates for Oracle Database, 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. Fully automated build of a Single Instance environment or a cluster (OVM3: Using the Deploycluster tool, OVM2: directly from Dom0) are possible, including automated network setup for N-node clusters.
The final Single Instance or 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.

CLOUD NEWS: In May 2019 these templates made a transition to the Oracle Cloud! it is now possible to deploy a Single Instance (or Oracle Restart) Oracle Database on the OCI Marketplace using a similar framework presented in these templates for a decade! Enjoy a smooth transition to the Oracle Cloud and amaze everyone with a fully deployed Oracle Database in only a few clicks and a few minutes!

  • All versions of the DB/RAC Templates are fully supported on Oracle VM 3 and Oracle VM 2, subject to current support policies.
  • The Oracle VM templates use a minimal installation of Oracle Linux 7 or Oracle Linux 6 system images. 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 a Single Instance or clusters of any number of nodes which includes Oracle Clusterware, Oracle Database, and Oracle Automatic Storage Management (ASM), patched to the latest, recommended patches.
  • The environment comes loaded with Swingbench, Oracle Cluster Health Monitor, OS Watcher, ASMLib rpms, and more tools.
  • During the installation process an Oracle Single Instance or 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 DeployCluster tool which now fully supports Single Instance, Oracle Restart (SIHA) or RAC deployments. The tool leverages the Oracle VM 3 API so that given a set of VMs it quickly boots them up sends the needed configuration details, and an automated Single Instance or cluster build is initiated, without requiring the user to login to Dom0, any of the involved VMs or Oracle VM Manager.

Documentation for Oracle VM 3 users: DeployCluster Tool

Note: For Deploycluster to function properly, an OVMAPI enabled OS disk (released since 2012) must be used in an Oracle VM 3 Manager and Server framework.

Use DeployCluster version 3.x for deployments on Oracle VM 3.3/3.4 or higher; use DeployCluster version 2.x for deployments on Oracle VM 3.2 or lower.

Single Instance and Oracle 12c support comes with deploycluster version 2.0 or above.

See DeployCluster documentations for additional details.
