DevOps automation is often associated only with tools that work with Virtual Machines at the hypervisor or operating system level. Automation is a key technique used to differentiate the DevOps model from the traditional operational model and it can be expanded to work beyond the VMs. In Oracle VM (OVM) environments, much of the automation is provided via Enterprise Manager, but there are other options. In March of 2017, Oracle released Oracle Database Enterprise Edition 12.2 for on-premises clients. This new database version included many new features for the DBA, as well as a few tools that enable DevOps type of automation practices to be driven by the Database Administrator.

One of these new abilities is a feature called “VM Manager Agent for Grid Infrastructure”. This new ability that is built into Oracle Clusterware allows it to add virtual machines as a Clusterware resources, managed through the RESTful API interface built into the Oracle VM Manager. This enables the Clusterware to manage a VM as a Clusterware resource, without requiring any interaction with the VM guest OS, effectively turning the VM into a black box to the DBA. An example use case is stopping and starting a VM running Oracle Database Firewall by using Oracle Clusterware.
