Oracle Autonomous AI Database

Known issues for Oracle Autonomous AI Database (ADW) with Resource Analytics.

ADW creation fails with the error: Database private endpoint does not have a DNS label

Details
When creating the ADW, it fails with the error: 
com.oracle.bmc.model.BmcException: Error returned by CreateAutonomousDatabase operation in Database service.
(400, InvalidParameter, false) 
The operation failed because the ocid1.vcn.oc1.iad.... of the Autonomous Database private endpoint does not have a DNS label.

You selected a subnet that doesn't have DNS enabled. This can happen if you're on a Fast Connect or if you cleared DNS when creating the subnet.

Workaround

Create a VCN or subnet with DNS enabled.

The following service limits were exceeded: adw-total-storage-tb.

This indicates that the compartment level ADW storage limit has been exceeded.

Incorrect AutoScaling setting of Autonomous AI Database instance

Details
For Resource Analytics instances installed between 24th September 2025 and 3rd November 2025, the Autonomous AI Database instance created has the autoscale settings of Compute (ECPU) and storage set to OFF From 3rd November 2025 onwards, this setting has been changed to ON.

Workaround
Change the setting to your preference by following these steps:
  1. In the OCI Console, navigate to Autonomous AI Databases.
  2. In the left-side navigation menu, select Oracle Database.
  3. Select Autonomous AI Database.
  4. On the Autonomous AI Databases page, select the name of the database you want to manage.
  5. You can manage the scaling in two ways:
    • On the database's details page, under Resource Allocation, select Edit in the section.
    • Under the More actions menu, select Manage scaling.
  6. Configure autoscaling by selecting the corresponding checkboxes to enable or disable ECPU and storage autoscaling.

Resource Analytics can't connect to the database

Details
When the database's private endpoint is removed, Resource Analytics can no longer connect to the database and send resource updates.
Workaround
You must delete Resource Analytics and then re-create it. In the new instance of Resource Analytics, do not change the Private Endpoint setting. Instead, you can enable public access while keeping the Private Endpoint enabled.
