Does Azure hosted Databricks Unity catalog support wallet based Oracle Connection?

Question

I have a Databricks Unity catalog in my Azure Databricks Service workspace, and I'm trying to create a connection to an Oracle Autonomous Database (ADB). In the Workspace UI, the "Create Connection → Oracle" option only accepts hostname / port / service name.

However, Oracle Autonomous Database does not support direct hostname-based connections. It requires a wallet-based (credentials file) connection instead.

Steps to reproduce:

Sign in to https://portal.azure.com

Open the Azure Databricks workspace → Launch Workspace

In the left panel, open Catalog

Click the + icon next to “Catalog”

Choose Add a connection

Select Oracle

The form does not provide any field to upload an Oracle wallet or configure wallet-based authentication.

Question

Does Unity Catalog in Azure currently support wallet-based Oracle Autonomous Database connections?
If yes, where should the wallet be uploaded?
If no, is this feature on the roadmap?

Thanks.

Hi @sarvesh Kulkarni

Thank you for contacting to Microsoft QA.

I see you’re trying to establish a connection between your Azure Databricks Unity Catalog and an Oracle Autonomous Database, but you're hitting a snag with the wallet-based authentication requirement. Let's break it down.

Currently, Unity Catalog in Azure Databricks does not support wallet-based connections directly from the UI when creating an Oracle connection. The "Create Connection → Oracle" option primarily focuses on hostname/port/service name configurations, which do not facilitate the wallet-based approach required by Oracle ADB.

Options You Can Consider:

JDBC Connection: You might want to use a JDBC Unity Catalog connection, which allows for more flexibility in connecting to external databases. You would need to set this up in a way that accommodates wallet-based authentication.

Contact Support: Since the wallet-based authentication is a specific Oracle requirement not currently handled through the UI, it would be prudent to contact Azure support to confirm if there is a workaround or if this feature is on the roadmap for future releases.

Follow-Up Questions:

To assist you better, here are a few follow-up questions:

• Have you explored using JDBC connections with any custom configurations to see if that suits your requirements?
• Are you aware of any existing API or CLI methods in Databricks that might allow you to set up wallet-based authentication indirectly?
• Would you need help with specific configurations for setting up JDBC, or are you looking for guidance on a different aspect?
