Oracle RAC is a key component of the Oracle Enterprise grid architecture. The deployment of Oracle RAC requires the installation of Oracle Grid cluster infrastructure，the configuration of parameters for operating systems and shared disks，and the installation and patching of system dependency packages. Aiming at the complexity of deploying Oracle RAC，a practical method of deploying RAC based on Oracle VM templates is proposed. Oracle VM provides an innovative approach to deploying a fully configured software stack by offering pre-installed and pre-configured software images. Use of Oracle VM eliminates the installation and configuration costs. The project practice shows that using Oracle VM templates can deploy Oracle RAC within one hour，which greatly improves the efficiency and success rate. The stability of deploying RAC based on Oracle VM templates needs to be further tested in the actual production environment，but this method is very suitable for its use in the teaching environment of colleges.
