Oracle Virtualization Templates Best Practices for Rapid Oracle Database Deployment

Oracle Virtualization application driven architecture is designed to enable rapid application deployment. With the use of Oracle Virtualization 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 Virtualization Templates for Oracle Database provide a framework that fully automates the creation of a Single Instance, Oracle Restart (Single Instance/HA) or Oracle Real Application Clusters (RAC) configurations in a Oracle VM and Oracle KVM/OLVM environments. In a matter of minutes the versatile and powerful Oracle Virtualization 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.

The templates are provided for both Oracle KVM, managed by Oracle Linux Virtualization Manager (OLVM) as well as traditional Oracle VM (Xen based) platforms.

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 test as well as production environments.

Templates for Oracle VM environments:

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

For more information about the Oracle Virtualization 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 database cluster are possible on OLVM & OVM3: Using the Deploycluster tool (OVM2: directly from Dom0), 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" (PDF) and "Oracle Database and Oracle Real Application Cluster on Oracle Linux KVM" technical white papers.

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 powering these templates for over 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!

DeployCluster Tool for Oracle KVM/OLVM and Oracle VM 3

Oracle KVM/OLVM and Oracle VM 3 users can benefit from a DeployCluster tool which fully supports Single Instance, Oracle Restart (SIHA) or RAC deployments. The tool leverages the Oracle KVM/OVIRT API and Oracle VM 3 API respectively to help speeding and automating the deployment of complex sets of VMs in a single command by creating (on OLVM), booting them up and sending the needed configuration details, and an automated Single Instance or cluster build is initiated, without requiring the user to login to any of the involved VMs, Oracle KVM Servers, Oracle Linux Virtualization Manager or Oracle VM Manager!

Documentation for Deploycluster / KVM/OLVM users:  DeployCluster Tool Deployment Guide for Oracle Linux Virtualization Manager - OLVM (PDF) 

Documentation for Deploycluster / Oracle VM 3 users: DeployCluster Tool for Oracle VM (PDF) .

Note: For Deploycluster to function properly please download and use the correct version based on the installed framework (do not mix between Oracle VM and Oracle KVM/OLVM). The tool is only officially supported with these published Oracle Virtualization Database Templates.

Use DeployCluster for Oracle KVM/OLVM version 4.x for deployments on Oracle KVM/OLVM 4 or higher;

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

Use DeployCluster for Oracle VM 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.
