Oracle Call Interface (OCI) and Oracle Database Instant Client now can retrieve a Microsoft Entra ID (formerly Azure AD) OAuth2 token directly from Entra ID instead of relying on a separate script or process to retrieve the token first. This design improves the interactive flow between the database server and the client when users connect to the database (for example with SQL*Plus).
Business Benefit: This enhancement simplifies the configuration that an end-user must perform in order to retrieve tokens. In previous releases, the end-user had to run a script to get the token from Entra ID before starting SQL*Plus or any other OCI utilities. Now, the token retrieval is part of OCI. This enhancement is similar to recent enhancements with the JDBC-thin and ODP.NET core and managed clients.
