Add Users To Specific Consumer Groups In Autonomous Database (Doc ID 2929587.1)

Last updated on MARCH 01, 2023

Applies to:

Autonomous Database on Shared Infrastructure - Version N/A to N/A
Information in this document applies to any platform.


Resource Managers or Consumer Groups or Service names are the integral part of Autonomous Databases as they manage the workload based on the performance characteristics of the Application. Autonomous Database comes with 5 preconfigured database services, HIGH, MEDIUM, LOW, TP and TPURGENT. The services control the priority of the sessions when the system is under resource pressure and some control the parallel degree used. By default, queries will execute serially when connected to the TP, TPURGENT and LOW services.
Users can specify a parallel degree on an object or uses optimizer hints to trigger parallel execution to be used when connected to the TP and TPURGENT services. Queries will be automatically executed in parallel when sessions are connected to the HIGH and MEDIUM services.

For detail, pls check manage concurrency

There are cases where we see a lot of application users misusing the consumer groups to their advantage and in doing so leading to performance overhead in the database.
So here in this blog we are going to show how to restrict users to certain consumer groups using database vault built into autonomous database.
One of the many security capabilities built into Autonomous Database is Database Vault. Database Vault implements powerful, unique security controls that restrict access to application data by privileged database users and enforce context-aware policies for data access by any user. Database Vault reduces the risk of insider and outside threats and addresses common compliance requirements.
