With the latest Release Update, you can now configure the database in a DB system to use OCI Identity and Access Management (IAM) authentication and authorization to allow IAM users to access the database with IAM credentials.

As of this release, IAM authentication and authorization:

• will be available to enable on newly provisioned databases in a DB system and for existing virtual machines that have been patched to set the WALLET_ROOT system parameter.
• can not be used with databases configured with Data Guard.
