  A step-by-step Console walkthrough for putting compute and database resources on a fixed start/stop timetable. If you run development, test, or demo workloads on Oracle Cloud Infrastructure (OCI), some of those resources almost certainly sit idle for large parts of the day and night. OCI Resource Scheduler lets you put them on a fixed timetable — automatically stopping compute instances and databases when nobody needs them, and starting them again before the work day begins. This post walks through creating a schedule end to end in the OCI Console, based on a real auto-start/stop setup with separate application and database nodes. NOTE: I didn’t provide exact screenshots from the console to protect confidential data. What Resource Scheduler does Resource Scheduler is an OCI service for automatically starting and stopping resources on a recurring schedule. It supports compute instances and autonomous databases, and the Console notes that other resource types may be suppo...

  Introduction Oracle VM Server for x86 was a long-standing Oracle virtualization platform for running Linux, Oracle Solaris, and Microsoft Windows virtual machines on x86 hardware. For many Oracle customers, it became a familiar platform for Oracle Database, middleware, and application workloads. The platform decision has changed. Oracle VM 3 moved beyond its Premier and Extended Support periods and is now in Sustaining Support. Oracle’s Lifetime Support Policy lists Oracle VM 3 with Premier Support ending in March 2021, Extended Support ending in June 2024, and Sustaining Support continuing indefinitely. For enterprise production environments, that support status makes Oracle VM Server for x86 a legacy platform rather than a recommended foundation for new deployments. Oracle’s current x86 virtualization direction is based on Oracle Linux KVM, managed by Oracle Linux Virtualization Manager, commonly called OLVM. Oracle describes OLVM as a server virtualization management p...
