Managing Autonomous Exadata VM Clusters

An Autonomous Exadata VM Cluster is a set of symmetrical VMs across all Compute nodes.

Autonomous Container and Database run all the VMs across all nodes enabling high availability. It consumes all the resources of the underlying Exadata Infrastructure.

After you have created the Autonomous Exadata VM Cluster, you can create up to 12 Autonomous Container Database resources on it, depending on the capacity of your Exadata Infrastructure hardware, as described in Available Exadata Infrastructure Hardware Shapes.

About Autonomous Exadata VM Clusters

  • Please contact your Oracle sales representative to understand the infrastructure upgrades required for supporting Oracle Autonomous Databases.
  • Create multiple Autonomous Exadata VM Clusters on a single Exadata Infrastructure resource.
  • Create both Autonomous Exadata VM Clusters and Exadata VM Clusters on the same Exadata Infrastructure.
  • Support for multiple VM Clusters lets you:
    • Schedule separate maintenance runs for each Autonomous VM Cluster on the same Exadata Infrastructure.
    • Choose different license models for Autonomous Databases on the same Exadata Infrastructure.
    • Create and test Autonomous Data Guard between Autonomous Exadata VM Clusters on the same Exadata Infrastructure.
    • Customize compute, storage, and memory of each Autonomous Exadata VM Cluster configuration for the intended workload.

Resource Terminology

It is important to understand the various terms used with resource allocation and usage. So, let's look at the important terms you see on the Oracle Cloud Infrastructure (OCI) console and understand what they mean:

  • Available CPUs: CPUs available for allocation to provision new Autonomous Databases or scale existing Autonomous Databases.
  • Provisioned CPUs: Total CPUs allocated for all the Autonomous Database within the Autonomous VM Cluster.
  • Reserved CPUs: Total CPUs reserved to support auto-scaling of Autonomous Databases, Autonomous Database failover on node failure, and lifecycle management of empty Autonomous Container Databases.
  • Reclaimable CPUs: Total CPUs from all terminated and scaled-down Autonomous Databases in all the Autonomous Container Databases within the Autonomous VM Cluster.Reclaimable CPUs are not returned to the Available state until Autonomous Container Database is restarted.
  • Provisionable ACDs: Number of Autonomous Container Databases that can be created in the Autonomous VM Cluster.
  • Provisioned ACDs: Number of Autonomous Container Databases that have been created in the Autonomous VM Cluster.
  • Non-provisionable ACDs: Number of Autonomous Container Databases that cannot be created because of a shortage of available CPUs in the Autonomous VM Cluster.
  • Total Storage (in TBs): Total storage allocated to the AVMC.
  • Available Storage (in TBs): Storage available for Autonomous Databases’ use in this AVMC.
  • Used Storage (in TBs): Storage currently used by Autonomous Database(s) in this AVMC.
  • Memory per CPU (in GBs): Memory allocated to the AVMC per CPU.

      All DB Servers that have the minimum resources to create an Autonomous VM Cluster are selected by default.
      1. Click Edit DB Server selection for VM placement to allocate VM resources.
      2. In the resulting Add Virtual Machines dialog, select a minimum of two database servers for VM placement. Maximum resources available for allocation per VM are based on the number of database servers selected.
        Note

        If the DB server is not added to the VM Cluster Network resources, then that DB server cannot be selected.
      3. Click Save Changes.
      Note

      The minimum and maximum values for these parameters change in relation to each other, for example, the OCPU count allocation will impact the number of ACDs you can create.

      Compute Model: Choose a compute model for your Autonomous Exadata VM Cluster resource.

      The default model is ECPU. ECPU is based on the number of cores elastically allocated from a pool of compute and storage servers.

      Click Change compute model if you wish to select OCPU. OCPU compute model is based on the physical core of a processor with hyper-threading enabled.

      Note

      The compute model chosen here will apply to all the Autonomous Container Databases and Autonomous Database instances created in this Autonomous Exadata VM Cluster resource.
      • VM Count: Number of database servers selected for the Autonomous Exadata VM Cluster. You cannot modify the VM count.
      • Maximum number of Autonomous Container Databases for the Autonomous VM Cluster: The number of ACDs specified represents the upper limit on ACDs. These ACDs must be created separately as needed. ACD creation also requires 2 available OCPUs or 8 available ECPUs per node.
      • CPU count per VM: Specify the CPU count for each individual VM. The minimum value is 5 OCPUs or 20 ECPUs per VM.
      • Database memory per CPU (GB): The memory per OCPU allocated for the Autonomous Databases in the Autonomous Exadata VM Cluster.
      • Allocate Storage for Local Backups: Check this option to configure the Exadata storage to enable local database backups.
      • Autonomous Database storage for the Autonomous VM Cluster (TB): Data storage allocated for Autonomous Database creation in the Autonomous VM Cluster.

      • No preference: The system assigns a date and start time for infrastructure maintenance.
      • Specify a schedule: Choose your preferred month, week, weekday, start time, and lead time for infrastructure maintenance.
        • Under Maintenance months, specify at least one month for each quarter during which Exadata infrastructure maintenance will take place. You can select more than one month per quarter. If you specify a long lead time for advanced notification (for example, 4 weeks), you may wish to specify 2 or 3 months per quarter during which maintenance runs can occur. This will ensure that your maintenance updates are applied in a timely manner after accounting for your required lead time. Lead time is discussed in the following steps.
        • Optional. Under Week of the month, specify which week of the month maintenance will take place. Weeks start on the 1st, 8th, 15th, and 22nd days of the month, and have a duration of 7 days. Weeks start and end based on calendar dates, not days of the week. Maintenance cannot be scheduled for the fifth week of months that contain more than 28 days. If you do not specify a week of the month, Oracle will run the maintenance update in a week to minimize disruption.
        • Optional. Under Day of the week, specify the day of the week on which the maintenance will occur. If you do not specify a day of the week, Oracle will run the maintenance update on a weekend day to minimize disruption.
        • Optional. Under Start hour, specify the hour during which the maintenance run will begin. If you do not specify a start hour, Oracle will pick the least disruptive time to run the maintenance update.
        • Under Lead Time, specify the minimum number of weeks ahead of the maintenance event you would like to receive a notification message. Your lead time ensures that a newly released maintenance update is scheduled to account for your required minimum period of advanced notification.
    2. Click Save Changes.
  6. Choose the license type you wish to use.

    Your choice affects metering for billing. You have the following options:
