Manage Resource Availability with Compartment Quotas

Oracle Autonomous Database on Dedicated Exadata Infrastructure supports the compartment quotas feature of Oracle Cloud Infrastructure.

Using this feature you can restrict, on a compartment by compartment basis, the availability of the following dedicated infrastructure resources in your tenancy:

  • OCPUs available to dedicated deployments of Autonomous Data Warehouse databases.

  • ECPUs available to dedicated deployments of Autonomous Data Warehouse databases.

  • Total data storage available to dedicated deployments of Autonomous Data Warehouse databases.

  • OCPUs available to dedicated deployments of Autonomous Transaction Processing databases.

  • ECPUs available to dedicated deployments of Autonomous Transaction Processing databases.

  • Total data storage available to dedicated deployments of Autonomous Transaction Processing databases.

Note:

Quotas are enforced only for provisioning databases and manually scaling their allocated CPUs up or down.
You can manage the compartment quotas to limit the availability of a given resource in a given compartment using the set, unset and zero policy statements. These policy statements are written in a simple declarative language that is similar to the IAM policy language.
  • set: Sets the maximum number of cloud resources that can be used for a compartment.
    For example, the following statement sets atp-dedicated-ocpu-count quota to 3 OCPUs in the compartment MyCompartment : 
    set database quota atp-dedicated-ocpu-count to 3 in compartment MyCompartment
  • unset: Resets quotas back to the default service limits.
    For example, the following statement resets the quota for atp-dedicated-ocpu-count in the entire tenancy: 
    unset database quota atp-dedicated-ocpu-count in tenancy
  • zero: Removes access to a cloud resource for a compartment.
    For example, the following statement disallows use of outbound email or notifications in the compartment MyCompartment:
    Zero email-delivery quotas in compartment MyCompartment
Zero notifications quotas in compartment MyCompartment

See Sample Quotas for more such examples and Quota Policy Syntax for an explanation of the anatomy of quota statements.

Compartment quotas are available on the OCI Console's Limits, Quotas and Usage page, which you can use to automatically generate quota statements. As a prerequisite, ensure you have the appropriate permissions to create quotas. See Policy Reference for the Quotas Service for more details.
