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.

Overview

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 for 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 Oracle KVM managed by Oracle Linux Virtualization Manager (OLVM).
 

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.

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.
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 Database and Oracle Real Application Cluster on Oracle Linux KVM" technical white papers.

Template Highlights

  • Deploycluster tool provides fully automated end-to-end Single Instance and Oracle Real Application Clusters deployments on Oracle KVM/OLVM.
  • All versions of the DB/RAC Templates are fully supported on Oracle KVM/OLVM, subject to current support policies.
  • The Oracle Virtualization templates use a minimal installation of Oracle Linux 9 and Oracle Linux 8 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 Virtualization 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 for Oracle KVM/OLVM

Oracle KVM/OLVM users can benefit from a DeployCluster tool which fully supports Single InstanceOracle Restart (SIHA) or RAC deployments. The tool leverages the Oracle KVM/OVIRT API to help speeding and automating the deployment of complex sets of VMs in a single command by creating, 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 Virtual Machines, Oracle KVM Servers or Oracle Linux Virtualization Manager.

Documentation for Deploycluster / KVM/OLVM users

Note: The tool is only officially supported with these published Oracle Virtualization Database Templates.
